<p><strong>Background: </strong>Seymour fractures are open, distal phalangeal physeal fractures with an associated nail-bed injury that occur in pediatric patients<sup>1</sup>. Although first described in the finger, an equivalent injury can occur in the distal phalanx of the great toe, often via a direct axial load at the apex of the toe, resulting in Salter-Harris type-I or II or juxta-epiphyseal fractures with a concomitant nail-bed laceration<sup>2-12</sup>. Closed reduction and splinting were initially recommended in these fractures<sup>1</sup>; however, they are now commonly treated with formal irrigation and debridement and the administration of prophylactic antibiotics in the acute setting in order to minimize the risk of complications such as infection<sup>10-12</sup>. To our knowledge, there are no detailed resources describing this surgical technique.</p><p><strong>Description: </strong>With the patient in the supine position, a nonsterile tourniquet is applied, the operative foot is thoroughly cleansed and prepared in a sterile field, and the operative extremity is exsanguinated. A digital block is then administered. With use of blunt instruments, the nail plate is removed or lifted to allow visualization of the underlying structures. A lacerated nail bed, or germinal matrix, will likely be observed, appearing as a glistening and highly vascularized soft-tissue structure at the proximal end of the nail, responsible for nail growth. Small incisions near the extension creases of the distal interphalangeal joint may be required to retract the eponychial fold and inspect the laceration and fracture site. Next, thorough irrigation and debridement are performed to clean the fracture site and remove any contaminants or nonviable tissues. The fracture is then manually reduced under direct visualization, ensuring proper alignment of bone fragments. Any interposed soft tissue, such as the germinal matrix or periosteum, is extricated from the fracture site with use of fine instruments. If the fracture is deemed unstable, percutaneous pinning with 0.045-in or 0.062-in Kirschner wires is performed to stabilize the fracture. Kirschner wires are inserted through the skin and driven across the fracture site and distal interphalangeal joint. Appropriate placement of pins is confirmed on fluoroscopy, and the nail bed is repaired with use of absorbable sutures. In cases with gross contamination or osteomyelitis, it is prudent to avoid pin fixation. A sterile dressing is applied, and the foot is immobilized in a well-padded short-leg cast or splint to protect the fracture and pin and to maintain alignment. Postoperatively, the patient is given a short course of oral antibiotics (e.g., cephalosporin) to prevent infection. Radiographic images are obtained at the first regular follow-up appointment (within 1 week postoperatively), and the Kirschner wires are removed once sufficient healing has occurred (typically 4 to 6 weeks postoperatively).</p><p><strong

<p><strong>Background: </strong>Hip decompression effectively treats early-stage osteonecrosis of the femoral head (ONFH) by slowing disease progression and potentially delaying joint replacement. Biological adjuvants like bone marrow aspirate concentrate (BMAC) and platelet-rich plasma (PRP) support bone regeneration and improve outcomes<sup>1-7</sup>. The present video article demonstrates a simple, coreless hip decompression technique with BMAC and PRP injection for early-stage ONFH.</p><p><strong>Description: </strong>The procedure is performed in the same operating room setting as traditional core decompression, with the patient supine on a radiolucent table for fluoroscopic guidance. One or both legs are draped free for access to the iliac crests. Bone marrow is harvested percutaneously from the anterior superior iliac crest with a trocar needle kit, centrifuged, and prepared for injection. We recommend precoating needles and syringes with 1:1,000 heparin to prevent clotting. The BioCUE System (Zimmer Biomet) is typically utilized for centrifugation. Hip decompression is performed with use of a trocar and cannula (PerFuse System; Zimmer Biomet), with subsequent injection through the cannula into the femoral head. A 0.5-cm skin incision is made. The trocar is placed lateral to the femur and advanced percutaneously through the lateral femoral cortex, with a starting point proximal to the lesser trochanter. The trocar is then advanced along the femoral neck into the necrotic region by performing mallet strikes on the instrument's strike cap. Anteroposterior and frog-leg lateral views assist in positioning the trocar within the necrotic area. Internal leg rotation, which aligns the patella upward, helps position the trocar horizontally parallel to the floor. Positioning is adjusted using repeated imaging as needed. Once the patient is positioned, the trocar is removed, leaving the cannula in place. With the cannula retracted 1 cm, a 30-mL syringe is utilized to inject BMAC and PRP into the necrotic lesion. Because of sclerotic resistance, substantial pressure is needed, but retraction of the cannula helps. Following injection, the cannula is withdrawn another 1 cm, and demineralized bone matrix is injected to prevent escape of the BMAC.</p><p><strong>Alternatives: </strong>Alternative treatments for ONFH include traditional core decompression with a sliding hip screw drill or an X-REAM device (Stryker), both of which carry a higher risk of fracture because of the larger diameter of the tract and require limited weightbearing postoperatively. Bone-cement injection can stabilize the femoral head but lacks regenerative properties. Core decompression with either BMAC or PRP alone, rather than in combination, also serves as an alternative treatment strategy. Open approaches, like osteotomy, are more invasive, have longer recovery times, and may complicate future hip arthroplasty if unsuccessful.</p><p><strong>Rationale: </strong>This technique enabl
背景:髋关节减压通过减缓疾病进展和潜在延迟关节置换术有效治疗早期股骨头骨坏死(ONFH)。生物佐剂如骨髓浓缩液(BMAC)和富血小板血浆(PRP)支持骨再生并改善结果1-7。本视频文章演示了一种简单的无芯髋关节减压技术,采用BMAC和PRP注射治疗早期ONFH。描述:该手术在与传统核心减压相同的手术室环境中进行,患者仰卧在放射光台上进行透视指导。一条或两条腿披挂,以便接触髂嵴。用套管针套装从髂前上嵴经皮采集骨髓,离心,准备注射。我们建议在针头和注射器上预先涂上1:10 000的肝素以防止凝血。BioCUE系统(Zimmer Biomet)通常用于离心。使用套管针和套管(PerFuse System; Zimmer Biomet)进行髋关节减压,随后通过套管注入股骨头。做一个0.5厘米的皮肤切口。套管针置于股骨外侧,经皮进入股骨外侧皮质,起始点在小转子近端。然后将套管针沿股骨颈推进到坏死区域,用木槌敲击套管针的打击帽。正位和蛙腿侧位视图有助于将套管针定位在坏死区域内。腿内旋转,使髌骨向上,有助于定位套管针水平平行于地板。根据需要使用重复成像来调整定位。一旦病人就位,将套管针取出,留下插管。将套管缩回1cm,用30ml注射器将BMAC和PRP注射到坏死病灶内。由于硬化阻力,需要大量的压力,但收回套管有帮助。注射后,将套管再拔出1cm,注入脱矿骨基质以防止BMAC逃逸。替代方案:ONFH的替代治疗方法包括滑动髋关节螺钉钻或X-REAM装置(Stryker)的传统核心减压,这两种方法都有较高的骨折风险,因为束直径较大,并且术后需要有限的负重。骨水泥注射可以稳定股骨头,但缺乏再生特性。单独使用BMAC或PRP进行核心减压,而不是联合使用,也可以作为一种替代治疗策略。开放入路,如截骨,侵入性更大,恢复时间更长,如果不成功,可能会使未来的髋关节置换术复杂化。原理:该技术可实现微创髋关节减压和辅助细胞治疗或移植,通常无需使用动力器械。这种方法避免了由于电动工具产生的热量而损伤骨骼的风险,保护了BMAC注射部位。患者通常在同一天出院,并允许立即完全负重,即使是双侧手术。预期结果:髋关节减压治疗ONFH的成功率不同8,9,但加入BMAC或PRP可能会改善结果1-3。Houdek等人报道,在35个髋关节中,减压加BMAC和PRP治疗皮质激素诱导的ONFH, 88%的患者在3年时避免了THA, 70%的患者在7年时避免了THA。1级或2级Kerboul角患者有90%的生存率,强调了BMAC和PRP的益处。重要提示:将套管针插入外侧皮质,定位于股脊远端和小转子近端,以减少医源性转子下骨折的风险。避免离软骨下皮质小于5mm,以防止关节面破裂或塌陷,尤其是偏心病变。如果在注射过程中出现阻力,将套管向外侧缩回几毫米以增加输送空间并降低压力。缩略语:BMAC =骨髓抽吸浓度onfh =股骨头骨坏死prp =富血小板血浆ap =正反位ortha =全髋关节置换术co =协会研究循环骨性分类mri =磁共振成像

背景:原发性骨肿瘤常发生在胫骨近端,是仅次于股骨远端的第二大常见部位1。治疗的挑战包括靠近神经血管结构、软组织覆盖范围有限、膝关节伸展受限以及术后并发症。本视频文章描述胫骨近端切除治疗骨肿瘤和假体重建联合内侧腓肠肌皮瓣。描述:胫骨近端切除采用前内侧入路。在确定切除水平后,将肿瘤整体切除,留下宽阔的自由边缘。使用大假体进行重建,腓肠肌内侧皮瓣用于覆盖假体和重建伸肌装置。替代方法:同种异体骨关节移植和同种异体移植物-假体复合材料允许骨储备的修复和宿主肌腱、韧带和囊的直接生物再附着。自体植骨采用腓骨作为供体部位。可以根据患者的解剖结构设计定制的植入物。当肿瘤广泛累及神经血管束时,应考虑截肢。理由:与其他治疗方法相比,大型假体重建具有以下优点:技术简单,立即负重,固定时间短。此外,大型假体没有同种异体移植物相关并发症的风险,如骨不连、骨折、软骨下塌陷、关节软骨退变和不稳定。预期结果:与同种异体移植重建相比,金属内假体患者并发症和截肢率较低,患者生存率较高7,9,10。自1977年以来,技术和设计的进步有助于减少骨-假体界面的机械应力,降低机械或结构失败率3,11,12。然而,尽管在设计上取得了进步,在所有保肢手术中,胫骨近端假体重建仍然表现出最不利的结果和功能,并伴有最高的并发症率1,9-11。研究报告5年生存率为45%至82%,10年生存率为45%至78% 1,13,感染和松动的翻修率为5年40%至15年73% 1,10,13。各种技术被用于连接膝关节伸肌机制并为胫骨近端重建提供覆盖7,8,10,14,15。各种研究都强调了将伸肌机制直接附着在大型假体上的重要性,这有助于最初的机械稳定性,对愈合和瘢痕形成至关重要7,10,16。带蒂肌皮瓣,特别是腓肠肌内侧或外侧,通常用于供血以帮助伤口愈合和生物重建伸肌机制7-9。尽管一些患者出现伸展滞后,但在随访期间观察到功能逐渐改善17。在我们225例胫骨近端切除的经验中,大型假体重建在5年和10年的存活率分别为82%和78%,使用固定和旋转铰链没有任何差异。然而,根据肌肉骨骼肿瘤学会(MSTS)系统17衡量,使用旋转铰链后,良好或极好的功能预后率明显更高。正如预期的那样,感染是最常见的并发症,发生27例(12%),其次是无菌性松动(13例,6%)、伸肌机制断裂(6例,3%)、假体断裂(4例,1.6%)和伤口开裂(4例,1.6%)1。重要提示:术前评估和影像学检查。进行彻底的病史和体格检查,评估综合征或家族史的证据,并利用影像学研究来评估肿瘤。患者体位和切口计划。患者仰卧位,确保胫骨近端有充分通路。准备并包扎病人;通过包括活检道在内的前内侧入路将切口置于肿块中心,并进行纵向切口。切除腓肠肌瓣。在确定近端血管后,继续解剖腓肠肌皮瓣,这通常是直接和快速的(即使在肿瘤切除后)。软组织的解剖及肿瘤切除边缘的确定。保护和收缩腓肠肌内侧皮瓣,然后分离和保护腘血管和胫后血管。深度清扫和关节切除术。如果分期和术前计划显示关节内没有肿瘤,则应进行关节内膝关节切除术。 经髌旁入路行关节切开术,在靠近股骨附着物处切开十字韧带。肿瘤切除。肿瘤标本经周向释放后,确定截骨水平,解剖与胫骨近端相连的任何剩余结构,以切除整个肿瘤。检查和止血。评估止血情况并送标本作病理分析。准备重建阶段,关闭手术部位。胫骨近端模数内假体重建。肿瘤巨型内假体因其多功能性、能够产生良好的功能结果、能够立即承重以及可能的成本效益而具有吸引力。伸肌机构重建。常用的入路包括内侧腓肠肌皮瓣。监测和术后护理。术后监测至关重要。严格的康复方案,全面伸展固定4周,然后渐进活动3个月,对于保证更好的功能效果至关重要。首字母缩写:GCT =巨细胞肿瘤hiv =人类免疫缺陷病毒hbv =乙型肝炎病毒hcv =丙型肝炎病毒-随访ct =计算机断层扫描mri =磁共振成像pet =正电子发射断层扫描suv =标准化摄取值echt (ISG/OS2) =化疗ymtx - hd =大剂量甲氨蝶呤ecdp =顺铂adm =多柔比星mftr = Kotz模块化股骨-胫骨重建系统hmrs = Howmedica模块化切除系统gmrs =全球模块化替代系统

<p><strong>Background: </strong>Extensor indicis proprius (EIP) transfer augmented with proximal extensor pollicis longus (EPL) stump lengthening restores thumb extension and optimizes function in cases of chronic EPL tendon ruptures, which impair hand dexterity and fine motor skills. Traditional EIP-to-EPL transfers often disrupt the natural oblique course of the EPL around the Lister tubercle, leading to functional deficits<sup>1-3</sup>. This dual-tendon transfer preserves anatomical alignment and improves thumb biomechanics, enhancing extension strength and the adduction moment arm at the carpometacarpal (CMC) joint.</p><p><strong>Description: </strong>The procedure involves 3 incisions over the index finger metacarpal neck, Lister tubercle, and dorsal thumb metacarpophalangeal joint.

背景:拇固有伸肌(EIP)转移与近端拇长伸肌(EPL)残端延长相结合,可恢复慢性拇固有伸肌肌腱断裂患者的伸展和功能优化,后者损害了手灵巧性和精细运动技能。传统的eip -EPL转移通常会破坏李斯特结节周围EPL的自然斜向路线,导致功能缺陷1-3。这种双肌腱转移保持解剖对齐,改善拇指生物力学,增强了手掌骨关节的伸展强度和内收力臂。手术包括食指掌骨颈、李斯特结节和拇指掌指关节背上的3个切口。取下EIP肌腱,将其远端残端与指跖伸肌缝合,并将近端残端取出进行转移。暴露远端和近端EPL残端,使用l形桡骨切口延长近端EPL,保留1厘米蒂用于翻转。将EIP和延长的EPL肌腱通过皮下,并使用粉状编织和增强技术涂覆到远端EPL。该手术在全清醒局部麻醉(WALANT)下进行,可以进行动态术中调整。术后使用夹板4周,随后使用可拆卸夹板4至8周,12周时停用。替代方案:手术替代方案包括桡腕短伸肌转移至外踝,手指小伸肌转移至外踝,肱桡肌转移至外踝,以及使用掌长肌移植物修复外踝。理由:与其他肌腱转移相比,EIP转移具有解剖学上的接近性和最小的供区发病率。然而,由于矢量错位,独立的EIP转移可能会降低伸展强度和活动范围4-7。目前描述的双转移技术通过保留EPL的天然路径,减少粘连和提高生物力学效率来解决这些限制。这项技术在需要高水平拇指功能的患者中特别有利,在减少残余缺陷的同时保留精细的运动控制和伸展力量。预期结果:该手术可改善拇指伸展、拇指内收和整体手部功能。Stirling等人1证明EIP-to-EPL转移提高了QuickDASH(缩短版手臂、肩膀和手的残疾问卷)得分(从29.7到15.2;p = 0.05),患者满意度高,无并发症。我们的增强方法建立在这些结果的基础上,减少了生物力学损失,保持了角度对齐,最大限度地降低了粘连风险,旨在实现更好的整体主动运动和功能恢复。在我们对15例患者的研究中,11例患者的结果被评为良好,4例患者的结果被评为一般,平均DASH评分为5.5。重要提示:在EPL延长时保留1厘米的椎弓根,以保持血管通畅并促进翻转。避免过紧,防止指间关节僵硬。确保一个光滑的皮下隧道,以减少摩擦和粘连。避免EPL方向不对准,这会影响拇指的伸展和内收。缩略语:EPL =拇长伸肌cmc = carpometacarpalEIP =拇固有伸肌ecrb =桡腕短伸肌edm =指短伸肌ibr = brachioradialisTAM =总主动运动mcp = metcarpophalangealip = interphalangealWALANT =全清醒局麻edc =指长伸肌

Background: Hemi-hamate osteochondral grafting is a surgical technique that is utilized to reconstruct the proximal interphalangeal (PIP) joint in cases of unstable dorsal fracture-dislocation with >50% articular surface involvement. However, hemi-hamate osteochondral grafting can be technically challenging, has been reported to have various technical modifications, and can lead to complications such as overstuffing of the joint. This surgical technique article describes successful PIP joint reconstruction with use of a hemi-capitate osteochondral graft, which may offer a viable alternative to hemi-hamate osteochondral graft.

Description: A volar approach to the PIP joint is utilized, and a trapezoidal incision is made. The skin, subcutaneous tissue, and neurovascular bundles are carefully retracted. The flexor tendon sheath is opened, and adhesions are released to expose the volar plate. The volar plate and collateral ligaments are reflected. The finger is hyperextended to expose the joint. Damaged cartilage and bone fragments are removed, and healthy cartilage is preserved. The capitate-3rd and -4th metacarpal joints are localized with use of fluoroscopy. A transverse incision is made over the joints, and the extensor retinaculum is incised. The capitate is exposed, and the required graft is marked and predrilled. An osteotomy is performed to harvest the graft. The capitate graft is trimmed and placed into the defect in the middle phalanx base. The graft is temporarily pinned with use of a Kirschner wire and then is secured with 2 bicortical screws. The middle phalanx is reduced, and free movement is confirmed. The volar plate is sutured to the collateral ligament. The flexor tendon sheath is passed beneath the flexor tendons to allow free gliding movements over the newly laid graft. The skin is sutured.

Alternatives: Hemi-hamate osteochondral graft is the most common alternative to hemi-capitate osteochondral graft.

Rationale: The capitate bone may offer several advantages over the hamate bone for PIP joint reconstruction. The capitate has a more uniform articular surface that closely resembles the middle phalanx base, which may reduce the risk of overstuffing1, Additionally, harvesting a graft from the capitate may be less likely to cause donor-site morbidity compared with harvesting from the hamate.

Expected outcomes: Hemi-capitate osteochondral graft is a promising technique for PIP joint reconstruction. In our previous article1, the patient achieved good PIP joint movement and stability at the time of the latest follow-up. The osteochondral capitate graft united well, and there were no signs of graft collapse or resorption. The patient had good range of motion and minimal pain, and was able to return to his previous work.

Important tips: Careful attention should be paid to graft size and placemen

背景:半钩骨软骨移植是一种用于重建近端指间关节(PIP)的手术技术,用于不稳定背侧骨折脱位,关节面受累50%。然而,半钩骨软骨移植在技术上具有挑战性,据报道需要进行各种技术修改,并可能导致并发症,如关节过度填充。这篇外科技术文章描述了使用半头骨软骨移植成功重建PIP关节,这可能是半钩骨骨软骨移植的可行替代方案。描述:采用掌侧入路进入PIP关节,并做一个梯形切口。小心地缩回皮肤、皮下组织和神经血管束。打开屈肌腱鞘,释放粘连,暴露掌侧板。掌板和副韧带被反射。手指过度伸展,暴露关节。受损的软骨和骨碎片被移除,健康的软骨被保留。利用x线透视定位掌骨第3和第4关节。在关节上做一个横向切口,切开伸肌支持带。露出头状骨,标记并预钻所需的移植物。进行截骨手术以获取移植物。将头状骨移植物修剪并置入中间指骨基部的缺损处。移植物暂时用克氏针固定,然后用2枚双皮质螺钉固定。中间方阵缩小,可以自由活动。掌侧板被缝合在副韧带上。屈肌腱鞘在屈肌腱下方通过,允许在新铺设的移植物上自由滑动。皮肤缝合好了。替代方案:半钩骨软骨移植是半头骨软骨移植最常见的替代方案。理论依据:在PIP关节重建中,头骨可能比钩骨有几个优势。头状骨具有更均匀的关节表面,与中指骨基部非常相似,这可以减少过度填充的风险1。此外,与钩骨相比,从头状骨移植移植物可能更不容易引起供体部位的发病率。预期结果:半头骨软骨移植是一种很有前途的PIP关节重建技术。在我们之前的文章1中,患者在最近一次随访时获得了良好的PIP关节运动和稳定性。骨软骨头状骨移植物愈合良好,无移植物塌陷或吸收的迹象。患者有良好的活动范围和最小的疼痛,并能够恢复他以前的工作。重要提示:应仔细注意移植物的大小和位置,以确保适当的关节一致性和稳定性。术后早期活动对防止关节僵硬很重要。缩略语:K-wire =克氏线;ds =指浅屈肌;dash =手臂、肩膀和手的残疾;vas =视觉模拟量表。

<p><strong>Background: </strong>Transfer of intercostal nerves to the radial nerve branch innervating the long head of the triceps muscle for elbow extension is indicated in patients with traumatic brachial plexus palsy that is either the pan-plexus type or C5-C7 palsy with no triceps muscle function. The procedure aims to restore triceps muscle function through the use of the intercostal nerves, which are expendable nerves, as donors.</p><p><strong>Description: </strong>The procedure is performed by first identifying the third to fifth intercostal nerves and coaptating them to the radial nerve branch innervating the long head of the triceps muscle. Three intercostal nerves are utilized because our previous study revealed that the use of 2 intercostal nerves resulted in poor outcomes<sup>1</sup>. Additionally, 3 intercostal nerves are comparable in size to the recipient nerve<sup>2</sup>. To identify the intercostal nerves, a curved incision is made over the sixth rib to the medial side of the arm, detaching the pectoralis major and minor from their distal insertion. The intercostal nerves are dissected from the inferior border of the third to fifth ribs. The radial nerve branch innervating the long head of the triceps muscle can be found distal to the teres major muscle as the first branch from the radial nerve via the same incision, at the medial side of the arm<sup>3</sup>. Subsequently, the 3 intercostal nerves are coaptated to the radial nerve branch to the long head of the triceps muscle.</p><p><strong>Alternatives: </strong>A deficit in active elbow extension may be deemed acceptable for certain patients who are amenable to utilizing gravity for performing such extensions. Nonoperative treatment could be contemplated for individuals falling into this category. Alternative surgical approaches may include nerve transfers utilizing other donor nerves, such as the ulnar or thoracodorsal nerves, or tendon transfer procedures.</p><p><strong>Rationale: </strong>Although active elbow extension may not be the primary focus when treating brachial plexus injury, a lack of active elbow extension affects various daily activities, such as overhead tasks, the use of a walking aid, and reaching for objects on a table<sup>4</sup>. Consequently, reanimating the muscle through the use of expendable donor nerves appears to be a suitable approach, particularly in young and active patients, aiming to restore function and enhance overall quality of life.

背景:外伤性臂丛神经麻痹(无论是泛臂丛型还是无三头肌功能的C5-C7型)的患者,都需要将肋间神经转移到支配肱三头肌长头的桡神经分支以伸展肘关节。该手术旨在利用肋间神经作为供体,恢复肱三头肌的功能。肋间神经是一种可消耗的神经。描述:该手术首先识别第三至第五肋间神经,并将其与支配肱三头肌长头的桡神经分支连接。我们使用了三条肋间神经,因为我们之前的研究显示使用两条肋间神经会导致不良的结果1。此外,肋间神经的大小与受体神经相当2。为了识别肋间神经,在第六肋骨上做一个弯曲的切口到手臂内侧,将胸大肌和胸小肌从远端插入处分离出来。肋间神经从第三到第五肋骨的下边缘被剥离。支配肱三头肌长头的桡神经分支位于大圆肌的远端,是桡神经的第一个分支,经过同样的切口,位于手臂内侧3。随后,3肋间神经与桡神经分支连接到肱三头肌的长头。替代方案:对于某些能够利用重力进行主动肘关节伸展的患者,主动肘关节伸展的缺陷可能被认为是可以接受的。对于属于这一类的个体,可以考虑非手术治疗。可选择的手术方法包括利用其他供体神经进行神经转移,如尺神经或胸背神经,或肌腱转移手术。理由:虽然主动肘部伸展可能不是治疗臂丛损伤的主要重点,但缺乏主动肘部伸展会影响各种日常活动,如头顶任务、助行器的使用和伸手取桌子上的物体4。因此,通过使用可消耗的供体神经来恢复肌肉活力似乎是一种合适的方法,特别是在年轻和活跃的患者中,旨在恢复功能并提高整体生活质量。因此,我们推荐将此手术作为其他手术干预措施的辅助,以帮助活动度高的患者恢复肘关节伸展以进行日常活动。预期结果:在我们之前的研究中,该方法显示了令人满意的结果1,2,与其他研究结果一致,报告了57%至80%的患者的良好结果5,6。在我们之前的研究中,65%的患者获得了良好的运动功能(医学研究委员会3至4级),没有观察到供体部位的发病率或呼吸系统并发症2。影响满意结果的负面因素包括超重(体重指数bbb25 kg/m2)7,8,手术手是非优势手2,以及从受伤到手术的时间过长9。重要提示:该手术推荐用于出现泛神经丛麻痹和上神经丛麻痹缺乏三头肌功能的患者。在后一种情况下,必须通过一系列检查、肌电图和术中神经刺激来确认三头肌肌肉缺损。既往肋骨骨折不作为手术禁忌症10。然而,有胸腔引流插入史的患者应谨慎,因为可能会损伤肋间神经。对于根撕脱伤,建议尽早手术治疗。纤维蛋白胶的使用可以考虑促进神经的适应。接受这种和其他臂丛手术的患者应充分了解相关的风险和益处。患者承诺参与术后康复是必要的。缩略语:ICN =肋间神经emrc =医学研究委员会。

The procedure aims to restore triceps muscle function through the use of the intercostal nerves, which are expendable nerves, as donors.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Description: &lt;/strong&gt;The procedure is performed by first identifying the third to fifth intercostal nerves and coaptating them to the radial nerve branch innervating the long head of the triceps muscle. Three intercostal nerves are utilized because our previous study revealed that the use of 2 intercostal nerves resulted in poor outcomes&lt;sup&gt;1&lt;/sup&gt;. Additionally, 3 intercostal nerves are comparable in size to the recipient nerve&lt;sup&gt;2&lt;/sup&gt;. To identify the intercostal nerves, a curved incision is made over the sixth rib to the medial side of the arm, detaching the pectoralis major and minor from their distal insertion. The intercostal nerves are dissected from the inferior border of the third to fifth ribs. The radial nerve branch innervating the long head of the triceps muscle can be found distal to the teres major muscle as the first branch from the radial nerve via the same incision, at the medial side of the arm&lt;sup&gt;3&lt;/sup&gt;. Subsequently, the 3 intercostal nerves are coaptated to the radial nerve branch to the long head of the triceps muscle.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Alternatives: &lt;/strong&gt;A deficit in active elbow extension may be deemed acceptable for certain patients who are amenable to utilizing gravity for performing such extensions. Nonoperative treatment could be contemplated for individuals falling into this category.

<p><strong>Background: </strong>Achieving adequate exposure can be difficult in cases of revision total hip arthroplasty (THA). Splitting the gluteus maximus muscle with use of a Kocher-Langenbeck approach is the most common technique when performing a posterior approach to the hip. However, superior exposure of the ilium is limited by the superior gluteal neurovascular bundle (SGB). Additionally, postoperative abductor weakness has been associated with this approach.</p><p><strong>Description: </strong>The extensile posterior approach (Adelaide approach) mobilizes the gluteus maximus muscle posteriorly and the gluteus medius muscle anteriorly to expose the ilium superior to the sciatic notch while minimizing the risk of injury to the SGB and preserving abductor function. Above the greater trochanter, the skin incision extends in a straight line toward the halfway point between the iliac tuberosity and the posterior superior iliac spine. It is helpful to find and protect the perforator vessels to identify the anterior edge of the gluteus maximus and develop a plane between the gluteus maximus and medius. The fascial incision is made with a slight Z shape for a modified Gibson approach. The gluteus maximus tendon is transected and the muscle is reflected posteriorly to expose the gluteus medius. The gluteus medius is elevated off the posterior gluteal line proximally to distally. The superior aspect of the SGB and transverse ligament are exposed, and the anterior aspect of the transverse sciatic notch ligament is released. The gluteus medius is mobilized anteriorly to expose the SGB, which is easier in a proximal-to-distal direction. Following the mobilization of the SGB, cage flanges can be passed underneath or augments bridged over the SGB without placing the SGB under undue tension.</p><p><strong>Alternatives: </strong>Nonoperative treatment should be attempted first, depending on the diagnosis and the patient's associated natural history. Once nonoperative treatment has been exhausted and revision THA is indicated, the traditional posterior, anterior, and direct lateral approaches can also be considered.

背景:在翻修全髋关节置换术(THA)的病例中,获得足够的暴露是困难的。采用Kocher-Langenbeck入路分离臀大肌是髋后入路手术中最常用的技术。然而,上显露髂骨受到臀上神经血管束(SGB)的限制。此外,术后外展肌无力与该入路有关。描述:可伸后入路(Adelaide入路)调动臀大肌后方和臀中肌前方,暴露坐骨切迹上方的髂骨,同时将SGB损伤的风险降至最低,并保留外展肌功能。在大转子上方,皮肤切口沿直线向髂粗隆和髂后上棘之间的中点延伸。识别臀大肌的前缘,在臀大肌和中肌之间形成一个平面,有助于发现和保护穿支血管。为改良的Gibson入路,筋膜切口呈轻微的Z形。横切臀大肌肌腱,肌肉向后反射露出臀中肌。臀中肌从臀后线近端到远端升高。显露骶胫束的上侧面和横韧带,释放坐骨横切迹韧带的前侧面。将臀中肌向前移动以暴露骶髂肌,这在近端到远端方向上更容易。在调动SGB之后,保持架法兰可以在SGB下面通过或在SGB上增加桥架,而不会使SGB承受过度的张力。替代方案:根据诊断和患者相关的自然病史,应首先尝试非手术治疗。一旦非手术治疗已经结束,需要进行THA翻修,也可以考虑传统的后路、前路和直接外侧入路。如果术中评估显示需要修改股骨假体,则前路入路股骨暴露有很大困难,并且与较高的医源性骨折风险相关。直接外侧入路通常会导致术后外展肌无力和Trendelenburg步态。传统的后入路使臀上神经处于较高的损伤风险,这可能导致术后外展肌无力。理由:翻修THA的常见适应症包括骨溶解、局部组织不良反应、复发性不稳定和无菌性髋臼松动。充分的暴露对于THA重建至关重要,同时将医源性神经损伤的风险降至最低。预期结果:在9例papprosky 3B缺损患者(5例骨盆不连续)中,术中肌电图显示所有患者均保留了臀肌的神经支配,术后外展功能良好。相比之下,在接受传统Kocher-Langenbeck入路的9例患者中,7例(78%)存在持续性外展肌无力。重要提示:分离并在SGB周围放置一个血管环,以允许臀中肌的充分活动,而不会对神经造成过度的紧张。缩略语:SGB =臀上神经血管束tha =全髋关节置换术fda =联邦药物管理局asis =髂前上棘sis =髂后上棘egt =大粗隆g =臀肌ddh =髋关节发育不良/p =状态后突=年龄stso =粗隆下缩短截骨肌ps =后上突nv =神经血管it =粗隆间肌电图

<p><strong>Background: </strong>Seymour fractures are a unique type of pediatric distal phalangeal fracture that can be easily misdiagnosed as a simple nail-bed injury or mallet finger<sup>1-3</sup>. Because of this potential for misdiagnosis, clear communication with consulting physicians regarding physical examination findings, such as nail plate avulsion and radiographic findings, is necessary. Seymour fractures involve the open physis and the germinal matrix, which become interposed in the fracture site, increasing the likelihood of infection. Open fractures are often displaced as a result of the distracting forces of the extensor and flexor tendons. This displacement, combined with the frequent association of nail bed lacerations, creates a high risk of complications such as infection and nonunion<sup>1-3</sup>. If left untreated or inadequately treated, these complications can lead to further surgery, prolonged antibiotic use, and potentially long-term impairment of hand function and cosmesis.</p><p><strong>Description: </strong>The procedure is performed with the patient under local anesthesia and with a glove tourniquet applied at the base of the operative finger. With use of blunt instruments such as a Freer elevator and a hemostat, the nail plate is carefully removed, and an eponychial flap is elevated proximally to expose the germinal matrix and fracture site. The interposed germinal matrix tissue at the fracture site is delicately elevated as a proximally based flap, fully revealing the fracture site for thorough irrigation, debridement, and reduction. Fracture fragments typically achieve anatomical alignment spontaneously upon removal of the interposed germinal matrix tissue. Reduction is verified visually and on fluoroscopy. The germinal matrix flap is meticulously sutured to the nail bed with use of 6-0 or 7-0 absorbable sutures, ensuring proper fracture alignment and correction of the pseudo-mallet deformity. For cases with instability, a 1.2- or 1.0-mm Kirschner wire may be placed retrogradely across the fracture and distal interphalangeal joint for additional stability. To support the repair, the nail plate or a substitute material may be temporarily placed beneath the eponychial fold; however, the nail plate is usually removed to reduce the risk of infection. The eponychial flap is reapproximated with simple interrupted sutures, and the procedure is concluded with the application of sterile, nonadherent dressings. The operative finger is immobilized with use of a below-the-elbow splint. All fracture reductions should be confirmed on postoperative radiographs.</p><p><strong>Alternatives: </strong>Alternative nonoperative treatments for Seymour fractures include closed reduction and splinting and/or the use of antibiotics.

背景:西摩骨折是一种独特类型的儿童远端指骨骨折,很容易误诊为简单的甲床损伤或槌状指1-3。由于有误诊的可能,与咨询医生就体检结果(如甲板撕脱和x线检查结果)进行明确的沟通是必要的。西摩骨折涉及开放的物理和生发基质,它们会介入骨折部位,增加感染的可能性。开放性骨折常因伸肌腱和屈肌腱的分散力而移位。这种移位,再加上甲床撕裂,造成感染和不愈合等并发症的高风险1-3。如果不及时治疗或治疗不当,这些并发症可能导致进一步的手术,长期使用抗生素,并可能导致手部功能和美容的长期损害。描述:该手术是在局部麻醉下进行的,在手术手指的底部使用止血带。使用较钝的器械,如弗里尔升降机和止血钳,小心地取出甲板,近端抬高一个髁突瓣以暴露生发基质和骨折部位。在骨折部位插入的生发基质组织作为近端基瓣被精致地抬高,充分显示骨折部位,以便彻底冲洗、清创和复位。骨折碎片通常在去除中间的生发基质组织后自发地实现解剖对齐。复位是目测和透视证实的。使用6-0或7-0可吸收缝线将生发基质皮瓣精心地缝合到甲床上,确保正确的骨折对齐和假槌状畸形的矫正。对于不稳定的病例,可以逆行放置1.2或1.0 mm克氏针穿过骨折和远端指间关节,以增加稳定性。为了支持修复,甲板或替代材料可以暂时放置在肘襞下;但是,通常会移除甲板以减少感染的风险。用简单的间断缝合线重新缝合颧瓣,手术结束时使用无菌、非粘附敷料。用肘下夹板固定手术手指。所有骨折复位应在术后x线片上确认。其他方法:西摩骨折的非手术治疗方法包括闭合复位、夹板和/或使用抗生素。其他手术治疗包括切开复位和使用克氏针和甲床修复内固定。原理:这种治疗西摩骨折的技术强调细致的甲床修复和选择性克氏针固定。不像单纯的夹板有骨不愈合和指甲畸形的风险,也不像常规的克氏针使用会增加感染和生长障碍的风险,我们的方法在实现稳定性和最小化并发症之间取得平衡。对于开放性骨折,彻底清创和使用抗生素是预防感染的首要措施。在不稳定或移位骨折中,当闭合复位不充分时,克氏针固定可确保骨折的稳定性。甲床修复是必不可少的,以防止畸形和促进最佳愈合。这种标准化的方法提供了平衡的策略,确保解剖复位、稳定性和感染风险最小化,特别是在开放性、不稳定或涉及钉床的骨折中。预期结果:经过适当的治疗,大多数患有西摩骨折的儿童都能完全康复,没有长期的问题。然而,重要的是要意识到潜在的并发症,如感染,指甲畸形,或生长障碍。研究表明,西摩骨折的早期治疗可显著降低并发症的风险。最近的一项研究发现,在受伤后48小时内早期清创和去除植入组织可将感染风险降低72%1。同样,在受伤后24小时内早期使用抗生素可使感染风险降低79%1-3。当使用早期清创和抗生素时,感染的风险降低了70%1。重要提示:疑似西摩骨折的儿童,有挤压伤的历史到指尖和开放的物理。仔细的临床检查是至关重要的,以避免误诊为简单的甲床损伤或锤状指。影像学评价对于确诊和评估骨折移位是必要的。用手指止血带实现无血现场,优化可视化。细致的甲床修复是防止指甲畸形和促进愈合的关键。对于不稳定的病例,1.2-或1。 0-mm克氏针可逆行穿过骨折和远端指间关节以增加稳定性。误诊或延误治疗可导致显著的并发症和长期发病率。不充分的清创和冲洗可增加感染和骨髓炎的风险。生发基质处理不当会导致指甲畸形或生长紊乱。不稳定的固定或过早的活动可导致不愈合或不愈合。鉴定和仔细提取插入的生发基质组织在技术上要求很高。实现小的移位碎片的稳定固定是具有挑战性的。预防长期并发症,如指甲畸形和生长障碍需要细致的手术技术和术后护理。我们密切监测愈合情况,并为患者提供手部治疗方面的指导,以帮助他们恢复手指的完整运动和功能。缩略语:PIP =近端指间;dip =远端指间。

Medial Approach Derotational Humeral Osteotomy in Patients with Brachial Plexus Birth Palsy. 臂丛分娩性麻痹患者内侧入路肱骨旋转截骨术。

<p><strong>Background: </strong>Medial-approach derotational humeral osteotomy is indicated in patients with brachial plexus birth palsy (BPBP) who have internal rotation contracture, a condition that substantially limits upper-extremity function and creates cosmetic concerns as a result of excessive internal rotation<sup>1</sup>. This procedure enhances the range of motion of the arm by surgically externally rotating the humerus, thereby facilitating essential activities such as bringing the hand to the mouth and neck without the need for compensatory movements. In addition, the medial approach offers cosmetic benefits; the incision along the inner arm is less conspicuous than those of traditional lateral approaches. The anteromedial humeral surface provides an ideal site for secure plate fixation, which promotes stability and optimal healing<sup>2</sup>.</p><p><strong>Description: </strong>Preoperative evaluation is critical to determine the precise degree of humeral rotation required. Both active and passive ranges of motion are measured-with special emphasis on shoulder adduction-to quantify available glenohumeral rotation. The active arc of internal rotation is recorded from the end range of passive external rotation, and the additional external rotation necessary for functional tasks (e.g., touching the back of the head), including scapulothoracic contributions, is determined passively. The operative plan involves calculating the degree of correction by subtracting the patient's active external rotation from the total required rotation, ensuring that adequate internal rotation is preserved for midline functions such as reaching the beltline. The goal is to achieve neutral glenohumeral alignment with restored external rotation, typically with a correction of approximately 60° to 70°.The procedure begins with the application of an arm tourniquet to minimize bleeding. A medial incision is made over the intermuscular septum and midshaft of the humerus while carefully protecting the ulnar and median nerves and brachial vessels. The intermuscular septum is identified and excised. The ulnar nerve is retracted posteriorly, whereas the median nerve and brachial artery are retracted anteriorly, thereby reducing the risk of nerve compression. The humeral diaphysis is then exposed, and the periosteum is elevated at the planned osteotomy site. A 6 to 8-hole plate (typically 2.7 or 3.5 mm) is temporarily applied, and proximal bicortical screws are inserted. A Kirschner wire is placed in the distal fragment to mark the desired correction angle, with its position verified via goniometry and visual assessment.

背景:内侧入路旋转肱骨截骨术适用于有内旋挛缩的臂丛分娩性麻痹(BPBP)患者,这种情况严重限制了上肢功能,并且由于过度内旋而造成美观问题1。该手术通过向外旋转肱骨来增强手臂的活动范围,从而促进基本活动,如将手伸向口部和颈部,而不需要代偿性运动。此外,医学方法提供美容方面的好处;沿臂内侧切口较传统外侧入路切口不明显。肱骨前内侧面为安全钢板固定提供了理想的位置,可促进稳定性和最佳愈合2。描述:术前评估对于确定所需肱骨旋转的精确程度至关重要。测量主动和被动的运动范围,特别强调肩部内收,以量化可用的肩关节旋转。从被动外旋结束范围记录主动内旋弧度,并被动确定功能任务(如触摸后脑勺)所需的额外外旋,包括肩胛骨的贡献。手术计划包括通过从所需的总旋转中减去患者的主动外旋转来计算矫正程度,确保为中线功能保留足够的内旋转,例如到达腰线。目标是在恢复外旋的情况下实现肩关节中立对准,通常矫正约60°至70°。首先使用手臂止血带以减少出血。在肱骨肌间隔和肱骨中轴处做内侧切口,同时小心地保护尺神经、正中神经和肱血管。肌间隔被识别并切除。尺神经向后牵开,正中神经和肱动脉向前牵开,从而减少了神经压迫的风险。然后暴露肱骨骨干,在计划截骨部位抬高骨膜。暂时使用6至8孔钢板(通常为2.7或3.5 mm),并插入近端双皮质螺钉。将克氏针放置在远端碎片中以标记所需的矫正角度,并通过角测量和视觉评估验证其位置。取下钢板后,使用振荡锯进行截骨。旋转肱骨使螺钉孔与克氏针对齐,重新应用钢板,使用标准加压螺钉技术完成最终固定2。备选方案:备选方案包括盂肱关节重建和外旋截骨。后者在三角粗隆上方进行,以改善外旋。基本原理:与其他治疗方法相比,内侧入路有几个明显的优势。由于内侧切口不太明显,增强了日常活动的功能定位,并提供了一种技术上直接的截骨复位和固定方法,从而改善了美观。肱骨的前内侧面有利于钢板的固定,确保稳定的固定和可预测的愈合。这些优点使得该手术特别适合需要功能和外观改善的BPBP的年龄较大的儿童和青少年1,2。预期结果:接受此手术的患者通常会有明显的外旋改善,导致手到嘴和手到脖子的运动更容易,这是日常活动所必需的。例如,Abzug等人1记录了截骨后外旋平均增加44°,而其他研究也类似地报道了肘关节屈曲和整体肢体对齐的增强2。尽管偶尔会出现并发症,如增厚性疤痕需要翻修,不完全矫正需要重复截骨,或肱骨骨干骨折远端到平台3,该手术被认为是相对安全的,具有很高的功能和美学满意度。然而,避免过度矫正是至关重要的,这可能导致固定的外旋姿势,从而导致功能丧失。重要提示:进行彻底的评估,包括影像学检查,以确定畸形的程度,并计划必要的旋转程度。与患者和家属讨论手术计划、预期结果和潜在风险。精确执行内侧切口,以尽量减少神经损伤和优化美容效果。确保细致的解剖以保护尺神经、正中神经和肱动脉。 在截骨部位切开骨膜以保留愈合潜力。使用克氏针和测角仪准确标记和验证校正角度。选择合适的钢板,在截骨前用近端双皮质螺钉固定。旋转后重新应用钢板,确保最终固定前对准。缩略语:BPBP =臂丛出生麻痹针=克氏针。
{"title":"Medial Approach Derotational Humeral Osteotomy in Patients with Brachial Plexus Birth Palsy.","authors":"J Terrence Jose Jerome","doi":"10.2106/JBJS.ST.24.00016","DOIUrl":"10.2106/JBJS.ST.24.00016","url":null,"abstract":"&lt;p&gt;&lt;strong&gt;Background: &lt;/strong&gt;Medial-approach derotational humeral osteotomy is indicated in patients with brachial plexus birth palsy (BPBP) who have internal rotation contracture, a condition that substantially limits upper-extremity function and creates cosmetic concerns as a result of excessive internal rotation&lt;sup&gt;1&lt;/sup&gt;. This procedure enhances the range of motion of the arm by surgically externally rotating the humerus, thereby facilitating essential activities such as bringing the hand to the mouth and neck without the need for compensatory movements. In addition, the medial approach offers cosmetic benefits; the incision along the inner arm is less conspicuous than those of traditional lateral approaches. The anteromedial humeral surface provides an ideal site for secure plate fixation, which promotes stability and optimal healing&lt;sup&gt;2&lt;/sup&gt;.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Description: &lt;/strong&gt;Preoperative evaluation is critical to determine the precise degree of humeral rotation required. Both active and passive ranges of motion are measured-with special emphasis on shoulder adduction-to quantify available glenohumeral rotation. The active arc of internal rotation is recorded from the end range of passive external rotation, and the additional external rotation necessary for functional tasks (e.g., touching the back of the head), including scapulothoracic contributions, is determined passively. The operative plan involves calculating the degree of correction by subtracting the patient's active external rotation from the total required rotation, ensuring that adequate internal rotation is preserved for midline functions such as reaching the beltline. The goal is to achieve neutral glenohumeral alignment with restored external rotation, typically with a correction of approximately 60° to 70°.The procedure begins with the application of an arm tourniquet to minimize bleeding. A medial incision is made over the intermuscular septum and midshaft of the humerus while carefully protecting the ulnar and median nerves and brachial vessels. The intermuscular septum is identified and excised. The ulnar nerve is retracted posteriorly, whereas the median nerve and brachial artery are retracted anteriorly, thereby reducing the risk of nerve compression. The humeral diaphysis is then exposed, and the periosteum is elevated at the planned osteotomy site. A 6 to 8-hole plate (typically 2.7 or 3.5 mm) is temporarily applied, and proximal bicortical screws are inserted. A Kirschner wire is placed in the distal fragment to mark the desired correction angle, with its position verified via goniometry and visual assessment. Following removal of the plate, an oscillating saw is utilized to perform the osteotomy. The humerus is rotated to align the screw holes with the Kirschner wire, the plate is reapplied, and final fixation is achieved with use of standard compression screw techniques&lt;sup&gt;2&lt;/sup&gt;.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Alternatives: &lt;/strong&gt;Alternatives include glenohumeral jo","PeriodicalId":44676,"journal":{"name":"JBJS Essential Surgical Techniques","volume":"15 3","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12348377/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144875890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
