Objective: The application progress of medical absorbable haemostatic material (MAHM) in hemostasis during orthoapedic surgery was reviewed, in order to provide reference for clinical hemostasis program.

Methods: The domestic and foreign literature on the application of MAHM for hemostasis in orthopedic surgery was extensively reviewed and summarized.

Results: According to biocompatibility, MAHM can be divided into oxidized cellulose/oxidized regenerated cellulose materials, chitosan and its derivatives materials, starch materials, collagen and gelatin materials, and fibrin glue materials, etc., which can effectively reduce blood loss when used in orthopedic surgery for hemostasis. Each hemostatic material has different coagulation mechanism and suitable population. Oxidized cellulose/oxidized regenerated cellulose, chitosan and its derivatives, starch hemostatic material mainly stops bleeding by stimulating blood vessel contraction and gathering blood cells, which is suitable for people with abnormal coagulation function. Collagen, gelatin and fibrin glue hemostatic materials mainly affect the physiological coagulation mechanism of the human body to stop bleeding, suitable for people with normal coagulation function.

Conclusion: Reasonable selection of MAHM can effectively reduce perioperative blood loss and reduce the risk of postoperative complications, but at present, single hemostatic material can not meet clinical needs, and a new composite hemostatic material with higher hemostatic efficiency needs to be developed.

目的综述医用可吸收止血材料(MAHM)在骨科手术止血中的应用进展,为临床止血方案提供参考:方法:广泛查阅并总结了国内外有关医用可吸收止血材料(MAHM)在骨科手术止血中应用的文献:结果:MAHM按生物相容性可分为氧化纤维素/氧化再生纤维素材料、壳聚糖及其衍生物材料、淀粉材料、胶原蛋白和明胶材料、纤维蛋白胶材料等,用于骨科手术止血可有效减少失血量。每种止血材料都有不同的凝血机制和适用人群。氧化纤维素/氧化再生纤维素、壳聚糖及其衍生物、淀粉止血材料主要通过刺激血管收缩和聚集血细胞来止血,适合凝血功能异常的人群。胶原蛋白、明胶和纤维蛋白胶止血材料主要通过影响人体生理凝血机制来止血,适用于凝血功能正常的人群:合理选择 MAHM 可有效减少围术期失血量,降低术后并发症风险,但目前单一止血材料已不能满足临床需求,需要开发止血效率更高的新型复合止血材料。

Objective: To review the research progress on bone repair biomaterials with the function of recruiting endogenous mesenchymal stem cells (MSCs).

Methods: An extensive review of the relevant literature on bone repair biomaterials, particularly those designed to recruit endogenous MSCs, was conducted, encompassing both domestic and international studies from recent years. The construction methods and optimization strategies for these biomaterials were summarized. Additionally, future research directions and focal points concerning this material were proposed.

Results: With the advancement of tissue engineering technology, bone repair biomaterials have increasingly emerged as an ideal solution for addressing bone defects. MSCs serve as the most critical "seed cells" in bone tissue engineering. Historically, both MSCs and their derived exosomes have been utilized in bone repair biomaterials; however, challenges such as limited sources of MSCs and exosomes, low survival rates, and various other issues have persisted. To address these challenges, researchers are combining growth factors, bioactive peptides, specific aptamers, and other substances with biomaterials to develop constructs that facilitate stem cell recruitment. By optimizing mechanical properties, promoting vascular regeneration, and regulating the microenvironment, it is possible to create effective bone repair biomaterials that enhance stem cell recruitment.

Conclusion: In comparison to cytokines, phages, and metal ions, bioactive peptides and aptamers obtained through screening exhibit more specific and targeted recruitment functions. Future development directions for bone repair biomaterials will involve the modification of peptides and aptamers with targeted recruitment capabilities in biological materials, as well as the optimization of the mechanical properties of these materials to enhance vascular regeneration and adjust the microenvironment.

目的综述具有募集内源性间充质干细胞(MSCs)功能的骨修复生物材料的研究进展:方法:广泛综述了近年来国内外关于骨修复生物材料的相关文献,尤其是那些旨在招募内源性间充质干细胞的生物材料。总结了这些生物材料的构建方法和优化策略。此外,还提出了该材料未来的研究方向和重点:结果:随着组织工程技术的发展,骨修复生物材料日益成为解决骨缺损的理想方案。间充质干细胞是骨组织工程中最关键的 "种子细胞"。从历史上看,间充质干细胞及其衍生的外泌体一直被用于骨修复生物材料;然而,间充质干细胞和外泌体来源有限、存活率低等挑战以及其他各种问题一直存在。为了应对这些挑战,研究人员正在将生长因子、生物活性肽、特异性适配体和其他物质与生物材料相结合,开发出促进干细胞募集的构建物。通过优化机械性能、促进血管再生和调节微环境,有可能创造出有效的骨修复生物材料,促进干细胞招募:结论:与细胞因子、噬菌体和金属离子相比,通过筛选获得的生物活性肽和适配体具有更强的特异性和靶向募集功能。骨修复生物材料的未来发展方向将包括在生物材料中修饰具有定向募集功能的多肽和适配体,以及优化这些材料的机械性能,以促进血管再生和调整微环境。

Objective: To analyze the accuracy of prosthesis size selection in Naton robot-assisted medial unicondyle knee arthroplasty by comparing the actual prosthesis size used during operation and the preoperative planning.

Methods: The clinical data of 100 patients (110 knees) who underwent Naton robot-assisted medial unicondylar knee arthroplasty between June 2023 and July 2024 was retrospectively analyzed, including 47 knees on left side and 63 knees on right side. There were 37 males (40 knees) and 63 females (70 knees) with a mean age of 65.4 years (range, 59-71 years). Body mass index was 22.2-28.6 kg/m 2 (mean, 25.4 kg/m 2). The disease duration ranged from 1 to 8 years (mean, 3.4 years). Preoperative planning was performed by Naton robotic surgical system based on lower limb CT data. The final prosthesis size after osteotomy was recorded and compared with the preoperative plan to analyse whether it was consistent with the preoperative plan, as well as the situation of knee flexion and extension gaps (<0.5 mm, >2.0 mm) corresponding to the different models of prostheses.

Results: During operation, 5 patients (5 knees) were treated with traditional UKA due to mechanical arm failure, software obstacles, significant bone amputation bias, or loose reference frame, and were excluded from the final analysis. The remaining 95 patients (105 knees) successfully received Naton robot-assisted surgery, and no related complications occurred. The prosthesis size was consistent with the preoperative plan in 101 knees (96.2%) on the femur side, 100 knees (95.2%) on the tibia side, and 97 knees (92.4%) on both femur and tibia sides. The prosthesis size was inconsistent in 3 cases (2.86%) on the femur side alone, 4 cases (3.81%) on the tibial side alone, and 1 case (0.95%) on both femur and tibial sides. Among the prostheses with different models, the flexion and extension gaps were less than 0.5 mm in 3 knees, the flexion gap was less than 0.5 mm and the extension gap was more than 2.0 mm in 3 knees, and the flexion gap was more than 2.0 mm and the extension gap was less than 0.5 mm in 2 knees.

Conclusion: The accuracy of prosthesis size selection for Naton robot-assisted medial unicondylar knee arthroplasty is relatively high.

目的通过比较手术中实际使用的假体尺寸与术前规划,分析纳顿机器人辅助内侧单髁膝关节置换术中假体尺寸选择的准确性:回顾性分析2023年6月至2024年7月期间接受纳顿机器人辅助内侧单髁膝关节置换术的100例患者(110膝)的临床资料,其中左侧47膝,右侧63膝。其中男性 37 人(40 个膝关节),女性 63 人(70 个膝关节),平均年龄 65.4 岁(59-71 岁)。体重指数为 22.2-28.6 kg/m2(平均 25.4 kg/m2)。病程为1至8年(平均3.4年)。纳顿机器人手术系统根据下肢CT数据进行术前规划。记录截骨后假体的最终尺寸,并与术前计划进行比较,分析其是否与术前计划一致,以及不同型号假体对应的膝关节屈伸间隙(2.0毫米)的情况:在手术过程中,有5名患者(5个膝关节)因机械臂故障、软件障碍、截骨偏差大或参考框架松动等原因而采用传统UKA进行治疗,并被排除在最终分析之外。其余95名患者(105个膝关节)成功接受了纳顿机器人辅助手术,未发生相关并发症。股骨侧101个膝关节(96.2%)、胫骨侧100个膝关节(95.2%)、股骨和胫骨侧97个膝关节(92.4%)的假体尺寸与术前计划一致。3例(2.86%)仅股骨一侧的假体尺寸不一致,4例(3.81%)仅胫骨一侧的假体尺寸不一致,1例(0.95%)股骨和胫骨两侧的假体尺寸均不一致。在不同型号的假体中,3个膝关节的屈伸间隙小于0.5毫米,3个膝关节的屈伸间隙小于0.5毫米且伸展间隙大于2.0毫米,2个膝关节的屈伸间隙大于2.0毫米且伸展间隙小于0.5毫米:结论:Naton机器人辅助内侧单髁膝关节置换术的假体尺寸选择准确性相对较高。

Objective: To evaluate the positional relationship between protective channel and sural nerve while treating acute Achilles tendon rupture with channel assisted minimally invasive repair (CAMIR) technique based on anatomical observations of cadaver specimens.

Methods: Twelve adult cadaveric lower limb specimens (6 left, 6 right) were utilized. A CAMIR device was implanted at a distance of 4 cm from the proximal end of the specimen to the Achilles tendon insertion. The skin was incised along the tendon's medial side, the sural nerve was dissected, and the positional relationship with the protective channel was observed. The distance from the sural nerve-Achilles tendon intersection to the calcaneal insertion, the vertical distance between protective channel and the calcaneal insertion, and the horizontal distance between the sural nerve and protective channel were measured by using vernier caliper.

Results: Anatomical examination demonstrated a variable positional relationship between the sural nerve and protective channel, with the sural nerve positioned above (8 specimens) or below (4 specimens) the protective channel. The distance from the sural nerve-Achilles tendon intersection to the calcaneal insertion was (105.67±14.94) mm, the vertical distance between protective channel and the calcaneal insertion was (93.20±9.57) mm, and the horizontal distance between the sural nerve and protective channel was (0.31±0.14) mm.

Conclusion: The use of CAMIR technique for the treatment of acute Achilles tendon rupture can effectively avoid iatrogenic injury to the sural nerve.

目的根据对尸体标本的解剖观察,评估在使用通道辅助微创修复(CAMIR)技术治疗急性跟腱断裂时,保护性通道与鞍神经之间的位置关系:方法:利用 12 个成人尸体下肢标本(左侧 6 个,右侧 6 个)。从标本近端到跟腱插入处 4 厘米处植入一个 CAMIR 装置。沿肌腱内侧切开皮肤,解剖硬神经,观察其与保护通道的位置关系。使用游标卡尺测量了腓肠神经-跟腱交叉点到小腿内侧插入点的距离、保护性通道和小腿内侧插入点之间的垂直距离以及腓肠神经和保护性通道之间的水平距离:解剖学检查显示,腓肠神经和保护性通道之间的位置关系各不相同,腓肠神经位于保护性通道上方(8 例标本)或下方(4 例标本)。硬神经-跟腱交点到小腿内侧的距离为(105.67±14.94)毫米,保护性通道和小腿内侧之间的垂直距离为(93.20±9.57)毫米,硬神经和保护性通道之间的水平距离为(0.31±0.14)毫米:结论:使用 CAMIR 技术治疗急性跟腱断裂可有效避免对硬脊膜神经的先天性损伤。

Objective: To review the application of cell derived decellularized extracellular matrix (CDM) in tissue engineering.

Methods: The literature related to the application of CDM in tissue engineering was extensively reviewed and analyzed.

Results: CDM is a mixture of cells and their secretory products obtained by culturing cells in vitro for a period of time, and then the mixture is treated by decellularization. Compared with tissue derived decellularized extracellular matrix (TDM), CDM can screen and utilize pathogen-free autologous cells, effectively avoiding the possible shortcomings of TDM, such as immune response and limited sources. In addition, by selecting the cell source, controlling the culture conditions, and selecting the template scaffold, the composition, structure, and mechanical properties of the scaffold can be controlled to obtain the desired scaffold. CDM retains the components and microstructure of extracellular matrix and has excellent biological functions, so it has become the focus of tissue engineering scaffolds.

Conclusion: CDM is superior in the field of tissue engineering because of its outstanding adjustability, safety, and high bioactivity. With the continuous progress of technology, CDM stents suitable for clinical use are expected to continue to emerge.

目的:回顾细胞衍生脱细胞细胞外基质(CDM)在组织工程中的应用:综述细胞衍生脱细胞细胞外基质(CDM)在组织工程中的应用:方法:广泛查阅并分析了与脱细胞细胞外基质在组织工程中的应用相关的文献:CDM是细胞及其分泌产物的混合物,通过体外培养细胞一段时间,然后对混合物进行脱细胞处理。与组织衍生脱细胞细胞外基质(TDM)相比,CDM 可以筛选和利用无病原体的自体细胞,有效避免了 TDM 可能存在的免疫反应和来源有限等缺点。此外,通过选择细胞来源、控制培养条件和选择模板支架,可以控制支架的组成、结构和机械性能,从而获得所需的支架。CDM 保留了细胞外基质的成分和微结构,具有良好的生物学功能,因此成为组织工程支架的重点:结论:CDM 在组织工程领域具有突出的可调性、安全性和高生物活性。随着技术的不断进步,适合临床使用的 CDM 支架有望不断涌现。

Objective: To analyze the impact of robot assistance on the restoration of limb length and offset distance in total hip arthroplasty (THA).

Methods: A retrospective analysis was conducted on the clinical data of 316 patients who underwent unilateral primary THA between September 2019 and August 2023. Among them, 117 patients underwent robot-assisted THA (group A), and 199 patients underwent conventional THA (group B). There was no significant difference between the two groups in the gender, age, or side of the hip replacement ( P>0.05); but there was a significant difference in the preoperative diagnosis ( P<0.05). The leg length discrepancy (LLD) and global offset (GO) dfference were measured on preoperative anteroposterior pelvic X-ray films, and absolute values were used for comparison between groups.

Results: The operations in both groups were successfully completed. Postoperative imaging measurements showed that the LLD and GO dfference in group A were significantly lower than those in group B ( P<0.05). Among them, group A had 32 cases (27.4%), 5 cases (4.3%), and 0 case (0) of LLD>3 mm, >5 mm, and >10 mm, respectively, while group B had 115 cases (57.8%), 75 cases (37.7%), and 22 cases (11.1%), respectively; and the differences in above indicators between groups were significant ( P<0.05). Group A had 40 cases (34.2%), 3 cases (2.6%), and 0 case (0) of GO dfference>5 mm, >10 mm, and >20 mm, respectively; group B had 103 cases (51.8%), 54 cases (27.1%), and 7 cases (3.5%), respectively. There was no significant difference in the proportion of patients with GO>20 mm between groups ( P>0.05), while there were significant differences in other indicators between groups ( P<0.05).

Conclusion: Compared with traditional THA, robot assisted THA has more advantages in restoration of limb length and offset distance.

目的分析机器人辅助对全髋关节置换术(THA)中肢体长度和偏移距离恢复的影响:对2019年9月至2023年8月期间接受单侧初次全髋关节置换术的316例患者的临床数据进行回顾性分析。其中,117 名患者接受了机器人辅助 THA(A 组),199 名患者接受了传统 THA(B 组)。两组患者在性别、年龄、髋关节置换侧等方面无明显差异(P>0.05);但在术前诊断(PResults:两组手术均顺利完成。术后影像学测量结果显示,A组的LLD和GO差值明显低于B组(分别为P3 mm、>5 mm和>10 mm,B组分别为115例(57.8%)、75例(37.7%)和22例(11.1%);组间上述指标差异显著(分别为P5 mm、>10 mm和>20 mm,B组分别为103例(51.8%)、54例(27.1%)和7例(3.5%)。GO>20毫米的患者比例组间差异无学意义(P>0.05),而其他指标组间差异有学意义(P结论:与传统THA相比,机器人辅助THA在恢复肢体长度和偏移距离方面更具优势。

Objective: To investigate the effect of different degrees of wound eversion on scar formation at the donor site of anterolateral thigh flaps by a prospective clinical randomized controlled study.

Methods: According to the degree of wound eversion, the clinical trial was designed with groups of non-eversion (group A), eversion of 0.5 cm (group B), and eversion of 1.0 cm (group C). Patients who underwent anterolateral femoral flap transplantation between September 2021 and March 2023 were collected as study subjects, and a total of 36 patients were included according to the selection criteria. After resected the anterolateral thigh flaps during operation, the wound at donor site of each patient was divided into two equal incisions, and the random number table method was used to group them ( n=24) and perform corresponding treatments. Thirty of these patients completed follow-up and were included in the final study (group A n=18, group B n=23, and group C n=29). There were 26 males and 4 females with a median age of 53 years (range, 35-62 years). The body mass index was 17.88-29.18 kg/m 2 (mean, 23.09 kg/m 2). There was no significant difference in the age and body mass index between groups ( P>0.05). The incision healing and scar quality of three groups were compared, as well as the Patient and Observer Scar Assessment Scale (POSAS) score [including the observer component of the POSAS (OSAS) and the patient component of the POSAS (PSAS)], Vancouver Scar Scale (VSS) score, scar width, and patient satisfaction score [visual analogue scale (VAS) score].

Results: In group C, 1 case had poor healing of the incision after operation, which healed after debridement and dressing change; 1 case had incision necrosis at 3 months after operation, which healed by second intention after active dressing change and suturing again. The other incisions in all groups healed by first intention. At 6 months after operation, the PSAS, OSAS, and patient satisfaction scores were the lowest in group B, followed by group A, and the highest in group C. The differences between the groups were significant ( P<0.05). There was no significant difference between the groups in the VSS scores and scar widths ( P>0.05).

Conclusion: Moderate everted closure may reduce the formation of hypertrophic scars at the incision site of the anterior lateral thigh flap to a certain extent.

目的通过前瞻性临床随机对照研究,探讨不同程度的伤口外翻对大腿前外侧皮瓣供区瘢痕形成的影响:根据伤口外翻程度,临床试验设计了不外翻组(A 组)、外翻 0.5 厘米组(B 组)和外翻 1.0 厘米组(C 组)。收集2021年9月至2023年3月期间接受股骨前外侧皮瓣移植手术的患者作为研究对象,根据选择标准共纳入36例患者。在手术中切除大腿前外侧皮瓣后,将每位患者供体部位的创口分为两个相等的切口,采用随机数字表法进行分组(n=24),并进行相应的处理。其中 30 名患者完成了随访,并纳入最终研究(A 组 18 人,B 组 23 人,C 组 29 人)。其中男性 26 人,女性 4 人,中位年龄为 53 岁(35-62 岁)。体重指数为 17.88-29.18 kg/m2(平均为 23.09 kg/m2)。组间年龄和体重指数无明显差异(P>0.05)。比较了三组的切口愈合和疤痕质量,以及患者和观察者疤痕评估量表(POSAS)评分[包括POSAS的观察者部分(OSAS)和POSAS的患者部分(PSAS)]、温哥华疤痕量表(VSS)评分、疤痕宽度和患者满意度评分[视觉模拟量表(VAS)评分]:C 组中有 1 例术后切口愈合不良,清创换药后愈合;1 例术后 3 个月切口坏死,积极换药并再次缝合后第二意向愈合。各组的其他切口均以第一意向愈合。术后 6 个月,B 组的 PSAS、OSAS 和患者满意度评分最低,A 组次之,C 组最高,组间差异有显著性(PP>0.05):结论:适度的外翻闭合可在一定程度上减少大腿前外侧皮瓣切口处增生性疤痕的形成。

<p><strong>Objective: </strong>To investigate the effectiveness of modified temporomandibular joint disc reduction and suture with tragus incision assisted by arthroscopy for temporomandibular joint anterior disc displacement (ADD).</p><p><strong>Methods: </strong>A clinical data of 30 patients (45 sides) with temporomandibular joint ADD, who met selective criteria and were admitted between September 2022 and February 2024, was retrospectively analyzed. Among them, 15 patients (23 sides) were treated with temporomandibular joint disc reduction and suture via small incision (open operation group), and 15 patients (22 sides) with modified temporomandibular joint disc reduction and suture with tragus incision assisted by arthroscopy (arthroscopy group). There was no significant difference in gender, age, disease duration, affected side, Wilkes-Bronstein stage, preoperative visual analogue scale (VAS) score, maximal interincisal opening (MIO), and temporomandibular joint dysfunction index (DI), craniomandibular index (CMI), palpation index (PI), and other baseline data between groups ( <i>P</i>>0.05). VAS score, MIO, and temporomandibular joint function indicators (PI, DI, CMI) of patients were recorded at 3 months after operation, and the difference (change value) of the above indicators between pre- and post-operation was calculated. At 1 week after operation, MRI was performed to evaluate the reduction of the articular disc compared to the preoperative image. The results were classified as excellent, good, and poor, with excellent and good being considered effective reduction. The condition of condyle process repair was observed by cone beam CT (CBCT) at 3 months after operation.</p><p><strong>Results: </strong>All incisions healed by first intention in the two groups. All patients were followed up 3-18 months (mean, 8.2 months). Facial nerve injury occurred in 3 cases in the open operation group and 1 case in the arthroscopy group, all of which returned to normal after physiotherapy and drug treatment. At 3 months after operation, MIO and VAS scores of both groups significantly improved when compared with those before operation ( <i>P</i><0.05), and temporomandibular joint function indicators (PI, DI, CMI) significantly decreased ( <i>P</i><0.05). The change values of MIO and temporomandibular joint function indicators in arthroscopy group were significantly higher than those in open operation group ( <i>P</i><0.05). There was no significant difference in the change value of VAS score between groups ( <i>P</i>>0.05). There was no recurrence during follow-up. Postoperative MRI review showed that the effective reduction rate of joint disc was 95.65% (22/23) in the open operation group and 95.45% (21/22) in the arthroscopy group, with no significant difference between groups ( <i>P</i>>0.05). Postoperative CBCT found that early and timely effective reduction of joint disc was conducive to condyle process repair and reconstruction.</p><p><strong>Conc
目的研究改良颞下颌关节椎间盘减压缝合术与外耳道切口辅助关节镜手术治疗颞下颌关节前椎间盘移位(ADD)的有效性:回顾性分析2022年9月至2024年2月期间收治的符合选择标准的30例(45侧)颞下颌关节ADD患者的临床资料。其中,15 名患者(23 侧)采用小切口颞下颌关节盘减压和缝合术(开放手术组),15 名患者(22 侧)采用改良颞下颌关节盘减压和缝合术(外耳道切口,关节镜辅助)(关节镜组)。两组患者的性别、年龄、病程、患侧、Wilkes-Bronstein分期、术前视觉模拟量表(VAS)评分、最大颏间隙(MIO)、颞下颌关节功能障碍指数(DI)、颅下颌关节指数(CMI)、触诊指数(PI)及其他基线数据均无明显差异(P>0.05)。术后3个月记录患者的VAS评分、MIO、颞下颌关节功能指标(PI、DI、CMI),计算上述指标在术前与术后的差异(变化值)。术后 1 周进行核磁共振成像,评估关节盘与术前图像相比的缩小情况。结果分为优、良、差三个等级,其中优和良为有效缩小。术后 3 个月,通过锥形束 CT(CBCT)观察髁突修复情况:结果:两组患者的所有切口均以第一意向愈合。所有患者均接受了 3-18 个月(平均 8.2 个月)的随访。开放手术组和关节镜手术组分别有 3 例和 1 例患者出现面神经损伤,经过物理治疗和药物治疗后均恢复正常。术后3个月,两组患者的MIO和VAS评分均较术前明显改善(PPPP>0.05)。随访期间无复发。术后 MRI 复查显示,开放手术组关节盘有效缩小率为 95.65%(22/23),关节镜组为 95.45%(21/22),组间差异无显著性(P>0.05)。术后 CBCT 检查发现,早期及时有效地缩小关节盘有利于髁突的修复和重建:结论:关节镜辅助下的改良颞下颌关节盘减张缝合术创伤小、术后并发症少、早期疗效好,在ADD的治疗中效果明显。
