Proximal focal femoral deficiency is a congenital transverse deficiency in which the femur is globally smaller with a typical proximal deformity at the hip that may include distal involvement of knees, leg, and feet. Congenital femoral deficiency (CFD) describes a broader spectrum of longitudinal deficiency inclusive of proximal focal femoral deficiency. CFD may also include lateral distal femoral hypoplasia, knee cruciate ligament deficiency, rotational instability, patellar dislocation, fibular hemimelia, ray absence, and contralateral limb involvement. Treatment intends to maximize function by limb equalization and deformity correction ranging from nonsurgical management using prosthetics to amputation and may include lengthening, shortening, and complex limb reconstruction. Management decisions depend on overall severity and the patient and family's preferences and priorities. Owing to its complexity, CFD is best treated by clinicians with considerable deformity treatment experience who can help guide decision making and embark on a treatment course that will maximize the functional outcome.
近端局灶性股骨缺乏症是一种先天性的横向缺乏症,其中股骨整体较小,髋部典型的近端畸形可能包括远端累及膝盖、腿和足。先天性股骨缺损(CFD)描述了更广泛的纵向缺损,包括近端局灶性股骨缺损。CFD还可能包括外侧股骨远端发育不全、膝关节交叉韧带缺乏、旋转不稳定、髌骨脱位、腓骨半缺、射线缺失和对侧肢体受累。治疗旨在通过肢体平衡和畸形矫正来最大限度地发挥功能,从使用假肢的非手术治疗到截肢,可能包括延长、缩短和复杂的肢体重建。管理决策取决于总体严重程度以及患者和家属的偏好和优先事项。由于其复杂性,CFD最好由具有丰富的畸形治疗经验的临床医生进行治疗,他们可以帮助指导决策并开始治疗过程,从而最大化功能结果。

Distal radius fractures are the most common type of upper extremity fractures, and their incidence is increasing. There has been a rise in the surgical treatment of distal radius fractures, primarily with volar locking plate fixation. Although this procedure is commonly done among orthopaedic surgeons, the role of pronator quadratus repair after fixation remains controversial. The pronator quadratus serves as a secondary forearm pronator and a dynamic stabilizer of the distal radioulnar joint. Aside from a functional role, repair of the pronator quadratus has been proposed to serve as a biologic barrier between the volar locking plate and the flexor tendons to minimize tendon irritation. In this narrative review, we discuss the current treatment trends, the surgical approach for volar locking plate treatment of distal radius fractures, and the anatomy and function of the pronator quadratus. We discuss the case for and against the repair of the pronator quadratus, both for function and prevention of flexor tendon irritation and rupture. The preponderance of high-level evidence demonstrates no benefit to pronator quadratus repair for pain relief or function. The current evidence does not conclusively support or refute pronator quadratus repair as a biologic barrier from the flexor tendons.
桡骨远端骨折是上肢骨折中最常见的类型,其发病率呈上升趋势。桡骨远端骨折的手术治疗越来越多,主要采用掌侧锁定钢板固定。虽然这种手术在骨科医生中很常见,但固定后旋前方肌修复的作用仍然存在争议。旋前方肌作为前臂第二旋前肌和远端尺桡关节的动态稳定器。除了功能性作用外,已提出修复旋前方肌作为掌侧锁定钢板和屈肌腱之间的生物屏障,以减少对肌腱的刺激。在这篇叙述性回顾中,我们讨论了目前的治疗趋势,掌侧锁定钢板治疗桡骨远端骨折的手术入路,以及旋前方肌的解剖和功能。我们讨论的情况下,支持和反对修复旋前方肌,既功能和预防屈肌腱刺激和断裂。高水平证据的优势表明,方旋肌修复对缓解疼痛或功能没有好处。目前的证据并不能决定性地支持或反驳方旋肌修复作为屈肌腱的生物屏障。

Evaluation and Management of Adolescents With a Stiff Flatfoot. 青少年僵硬扁平足的评估与处理。
Pub Date : 2022-04-26 DOI: 10.5435/JAAOS-D-21-00448

While flatfeet are normal in children, persistence into adolescence with associated pain or asymmetry warrants additional evaluation. Rigidity of a flatfoot deformity, whether a clinical report or evident on examination, should raise suspicion for pathology. The differential diagnosis includes tarsal coalition, neurogenic planovalgus, and peroneal spasticity. History must include pointed inquiry into birth and neurologic histories to probe for a source of central spasticity. Examination must include standing assessment of hindfoot and midfoot alignment. Hindfoot rigidity may be assessed by the double limb heel rise test and manual examination. Radiographs should include standing ankle (anterior-posterior and mortise) and whole foot (anterior-posterior, external rotation oblique, and lateral) images. Magnetic resonance imaging is more sensitive for identifying coalitions and better characterizes adjacent cartilage, subchondral edema, and tendon pathology, yet CT better characterizes the anatomy of a bony coalition. Conservative treatments are pathology-dependent and play a more prominent role in neurogenic or peroneal spastic flatfoot. Surgical management of coalitions is centered on coalition resection coupled with arthrodesis in the case of a talocalcaneal coalition with a dysplastic subtalar joint; concomitant planovalgus reconstruction is considered on a case-by-case basis.
虽然扁平足在儿童中是正常的,但持续到青春期并伴有相关的疼痛或不对称需要额外的评估。平足畸形的僵硬,无论是临床报告还是检查上的证据,都应该引起病理学的怀疑。鉴别诊断包括跗骨联合、神经源性平外翻和腓骨痉挛。病史必须包括对出生和神经病史的针对性调查,以探索中枢痉挛的来源。检查必须包括站立评估后足和中足对齐。后脚刚性可通过双足跟高试验和手工检查来评估。x线片应包括站立踝关节(前后位和榫位)和全足(前后位,外旋斜位和侧位)图像。磁共振成像对鉴别关节联合更敏感,能更好地表征邻近软骨、软骨下水肿和肌腱病理,而CT能更好地表征骨联合的解剖结构。保守治疗是病理依赖的,在神经源性或腓骨痉挛性扁平足中发挥更突出的作用。对于距跟关节联合伴距下关节发育不良的情况,联合手术治疗的重点是联合切除联合关节融合术;伴随的平外翻重建应视具体情况而定。

Thumb metacarpophalangeal (MCP) joint hyperextension is a well-established sequela of advanced carpometacarpal (CMC) joint arthritis. This deformity results in poor patient function because the ability to perform key pinch is negatively affected. For this reason, surgeons must consider the presence of an MCP deformity when addressing CMC arthritis. A variety of nonsurgical and surgical interventions have emerged. Surgical treatments can be grouped into four main categories: (1) volar plate advancement/capsulodesis, (2) tendon transfer and tenodesis, (3) sesamoidesis, and (4) arthrodesis. Surgical intervention is based on both the degree of deformity present and the surgeon preference. This review aims to clarify indications for various treatments of MCP joint hyperextension, outline commonly performed procedures, and report the published outcomes and potential complications of these interventions.
拇指掌指骨(MCP)关节过伸是晚期掌指骨(CMC)关节关节炎的一种公认的后遗症。这种畸形导致患者功能差,因为执行键捏的能力受到负面影响。因此,外科医生在治疗CMC关节炎时必须考虑是否存在MCP畸形。各种非手术和手术干预措施已经出现。手术治疗可分为四大类:(1)掌侧钢板推进/包膜固定术,(2)肌腱转移和肌腱固定术,(3)鞘成形术,(4)关节融合术。手术干预是基于存在的畸形程度和外科医生的偏好。本综述旨在阐明各种MCP关节过伸治疗的适应症,概述常用的治疗方法,并报告已发表的治疗结果和这些干预措施的潜在并发症。

Knowledge of anatomy and physiology of the meniscus is essential for appropriate treatment. The unique anatomy of the medial and lateral meniscus and blood supply play an important role in decision making. Controversy exists regarding the optimal treatment of meniscal tears including débridement, repair, root repair, and transplantation. The unique tear location and morphology thus plays an essential role in determination of appropriate treatment. Repair is generally advised in tear types with healing potential to preserve meniscal function and joint health.

Periprosthetic joint infection is a rare but potentially devastating complication of shoulder arthroplasty. The most conservative treatment approach is a two-stage revision involving interval placement of an antibiotic cement spacer. The purpose of this study was to contextualize the use of antibiotic spacers in the current treatment paradigm of shoulder periprosthetic joint infection and to review the history of shoulder spacers, the different types (eg, stemmed versus stemless and prefabricated versus handmade), the antibiotic composition and dosage, and their efficacy and complications.
肩关节周围感染是肩关节置换术中一种罕见但具有潜在破坏性的并发症。最保守的治疗方法是两阶段的翻修,包括间隔放置抗生素水泥隔离剂。本研究的目的是在当前肩关节假体周围感染的治疗范例中使用抗生素隔离剂,回顾肩关节隔离剂的历史,不同类型(例如,有柄与无柄,预制与手工),抗生素成分和剂量,以及它们的疗效和并发症。

Multiple meniscal repair techniques exist, and successful healing and excellent patient outcomes have been reported with a variety of all-inside and open techniques. Increased awareness and recognition of root tears and meniscocapsular separations are topics of recent interest. The ideal treatment of these injuries remains uncertain, and definitive recommendations regarding their treatment are lacking. Postoperative protocols regarding weight bearing and range of motion are controversial and require future study. The role of biologics in the augmentation of meniscal repair remains unclear but promising. An evidence-based individualized approach for meniscal repair focusing on clinical outcomes and value is essential.
存在多种半月板修复技术,各种全内和开放技术均已报道成功愈合和良好的患者预后。提高意识和认识的根撕裂和半月板囊分离是最近感兴趣的话题。这些损伤的理想治疗方法仍然不确定,并且缺乏关于其治疗的明确建议。术后关于负重和活动范围的方案是有争议的,需要进一步的研究。生物制剂在增强半月板修复中的作用尚不清楚,但很有希望。循证个体化半月板修复方法关注临床结果和价值是必不可少的。

Spinal cord stimulators (SCSs) and intrathecal pain pumps (IPPs) are implantable devices used in the management of chronic pain or spasticity. Complications, such as infection, lead migration/failure, cerebrospinal fluid leak, neurologic injury, and other medical complications, can occur after placement and may require surgical intervention. Orthopaedic surgeons may encounter patients with these devices and should have a basic understanding of their function. In addition, they should be aware that patients may have residual stenosis or deformity contributing to their symptoms; thus, spine surgery referral may be indicated. If a patient with a SCS or IPP is undergoing revision spinal surgery, a preoperative discussion regarding retention versus removal of the device is imperative because indications for device retention, revision, and removal are complex. This review summarizes potential complications and intraoperative considerations concerning the proper perioperative management of SCSs/IPPs and will provide evidence-based data regarding management strategies for these devices.
脊髓刺激器(scs)和鞘内疼痛泵(ipp)是用于治疗慢性疼痛或痉挛的植入式装置。并发症,如感染、铅迁移/衰竭、脑脊液泄漏、神经损伤和其他医学并发症,可在放置后发生,可能需要手术干预。骨科医生可能会遇到使用这些装置的患者,他们应该对其功能有一个基本的了解。此外,他们应该意识到,患者可能有残留的狭窄或畸形导致他们的症状;因此,可能需要脊柱外科转诊。如果患有SCS或IPP的患者正在进行脊柱翻修手术,术前关于保留或移除器械的讨论是必要的,因为器械保留、修复和移除的适应症是复杂的。本综述总结了SCSs/ ipp围手术期管理的潜在并发症和术中注意事项,并将为这些装置的管理策略提供循证数据。

Currently, no studies exist on transgender patients undergoing orthopaedic procedures within the orthopaedic literature at large. This echoes a trend within medicine in general, where despite their unique characteristics, transgender patients are largely ignored in medical research. As gender reassignment surgery becomes more commonplace and these patients' age into joint arthroplasties, orthopaedic surgeons will rapidly be faced with treating this patient group. Unique considerations include medical comorbidities commonly associated with the patient population, deep vein thrombosis risk while on cross-gender hormone therapy, surgical positioning considerations, and social support implications after surgery. In addition, risk reductions for possible future gender reassignment surgeries include consideration for extended perioperative antibiotics and diligent surveillance for implant ingrowth issues. An emphasis is placed on being comfortable with transgender patients to ensure equal access to health care while ensuring understanding and accuracy in describing the risks of surgery that are unique to this patient population.
目前,在骨科文献中没有关于变性患者接受骨科手术的研究。这与医学界的一个普遍趋势相呼应,尽管跨性别患者具有独特的特征,但他们在医学研究中基本上被忽视了。随着性别再分配手术的日益普及和这些患者进入关节置换术的年龄,骨科医生将迅速面临治疗这一患者群体的问题。独特的考虑因素包括通常与患者人群相关的医疗合并症,接受跨性别激素治疗时的深静脉血栓形成风险,手术体位考虑因素以及手术后的社会支持影响。此外,降低未来可能的性别重置手术的风险,包括考虑延长围手术期抗生素和对种植体生长问题的密切监测。重点放在与跨性别患者相处时感到舒适,以确保平等获得医疗保健,同时确保理解和准确描述这一患者群体特有的手术风险。
