    肩袖部分厚度撕裂(PTRCT)的患者通常伴有二头肌肌腱长头(LHBT)的病理。为了同时解决这两个条件,在关节镜肩袖修复术(RCR)时,可进行肱二头肌长头肌(LHB)腱切开术或肌腱固定术.这项研究旨在比较经肌腱RCR并发LHB肌腱固定术或肌腱切开术后的术后肩关节活动范围(AROM)和并发症。
    共有90例PTRCT患者符合本研究的纳入标准。接受撕裂完成和修复的患者,翻修手术,或LHB肌腱的开放性修复被排除。患者被分层为肌腱切开术,关节镜胸上肌腱固定术,或没有二头肌手术队列,并且在年龄上倾向匹配1:1:1,性别,身体质量指数,和吸烟状况。主要结果测量包括AROM前屈,绑架,外部旋转,6周时内旋,3个月,术后6个月。最终随访时严重僵硬的发展和肩袖再撕裂的发生率被记录为次要结果。
    当比较肌腱切开术和肌腱固定术时,发现肌腱切开术患者在3个月前屈曲时AROM增加(153.2°vs.130.1°,P=.004),外展(138.6°vs.114.2°,P=.019),和外部旋转(60.4°vs.43.8°,P=.014),向前屈曲的差异在6个月时仍然显着(162.4°与149.4°,P=.009)。队列之间任何平面的恢复间隔率都没有显着差异。此外,组间症状性再撕裂率无显著差异(P=0.458).严重术后僵硬率接近,但在肌腱切开术(4.2%)和肌腱固定术(29.2%)队列之间没有达到统计学意义(P=0.066)。吸烟状况是严重僵硬的显著预测指标(比值比,13.69;P=.010)。
    尽管队列之间的绝对AROM存在显着差异,对于接受PTRCT关节镜下经肌腱RCR的患者,没有发现进行肌腱切开术或肌腱固定术的决定对AROM恢复率有差异.值得注意的是,然而,短暂性僵硬并发症更常见于吸烟者,数据趋势表明,接受LHB肌腱固定术的患者发生僵硬的风险增加.总的来说,术后僵硬可能是多因素的,可归因于患者和手术特定因素,LHB肌腱切开术可能更适合有术后僵硬危险因素的患者。
    UNASSIGNED: Patients with partial thickness rotator cuff tears (PTRCTs) often present with concurrent pathology of the long head of the biceps tendon (LHBT). To address both conditions simultaneously, long head of the biceps (LHB) tenotomy or tenodesis can be performed at the time of arthroscopic rotator cuff repair (RCR). This study aims to compare postoperative shoulder active range of motion (AROM) and complications following transtendinous RCR with concurrent LHB tenodesis or tenotomy.
    UNASSIGNED: A total of 90 patients with PTRCTs met inclusion criteria for this study. Patients who underwent tear-completion-and-repair, revision surgery, or open repair of the LHB tendon were excluded. Patients were stratified into tenotomy, arthroscopic suprapectoral tenodesis, or no biceps operation cohorts and were propensity matched 1:1:1 on age, sex, body mass index, and smoking status. Primary outcome measures included AROM in forward flexion, abduction, external rotation, and internal rotation at 6 weeks, 3 months, and 6 months postoperatively. The development of severe stiffness and rates of rotator cuff retear at final follow-up were recorded as secondary outcomes.
    UNASSIGNED: When comparing the tenotomy and tenodesis cohorts, tenotomy patients were found to have increased AROM at 3 months in forward flexion (153.2° vs. 130.1°, P = .004), abduction (138.6° vs. 114.2°, P = .019), and external rotation (60.4° vs. 43.8°, P = .014), with differences in forward flexion remaining significant at 6 months (162.4° vs. 149.4°, P = .009). There were no significant differences in interval rates of recovery in any plane between cohorts. Additionally, there were no significant differences in rates of symptomatic retears between groups (P = .458). Rates of severe postoperative stiffness approached but did not achieve statistical significance between tenotomy (4.2%) and tenodesis (29.2%) cohorts (P = .066). Smoking status was a significant predictor of severe stiffness (odds ratio, 13.69; P = .010).
    UNASSIGNED: Despite significant differences in absolute AROM between cohorts, the decision to perform tenotomy or tenodesis was not found to differentially affect rates of AROM recovery for patients undergoing arthroscopic transtendinous RCR for PTRCT. Notably, however, transient stiffness complications were more commonly observed in smokers, and data trends suggested an increased risk of stiffness for patients undergoing LHB tenodesis. Overall, postoperative stiffness is likely multifactorial and attributable to both patient- and procedure-specific factors, and LHB tenotomy may be more appropriate for patients with risk factors for developing stiffness postoperatively.

    虽然研究评估了肩关节功能恢复和症状缓解的比较率,肱二头肌肌腱切开术和肌腱固定术之间的比较术后并发症发生率尚待评估。本研究的目的是使用国家管理数据库对肱二头肌肌腱切开术和肌腱固定术后30天的并发症发生率进行全面调查。从而为临床医生和患者就肱二头肌长头肌腱病变的最佳手术方法做出明智的决策提供有价值的见解。
    查询了国家外科质量改进计划数据库,以分析与肱二头肌肌腱切开术和肌腱固定术相关的术后并发症发生率和指标。提取了2012年至2021年的患者数据,评估相关变量以识别和比较这两种手术方法。调整和未调整的分析用于分析患者的人口统计学,合并症,手术时间,逗留的长度,再入院,不良事件,和每年的手术量,随着使用趋势,跨队列。
    总共11,527名患者中,264(2.29%),6826(59.22%),和4437(38.49%)进行了肌腱切开术,采用开放式修复的肌腱固定术,和关节镜修复的肌腱固定术,分别。肌腱切开手术时间([平均值±SD]:66.25±44.76分钟)短于开放肌腱固定术(78.83±41.82)和关节镜下肌腱固定术(75.98±40.16)。相反,与开放性肌腱固定术(.08±1.55)和关节镜下肌腱固定术(.12±2.70)相比,肌腱切开术患者的住院天数(0.88±4.86天)更长.对人口统计学和合并症进行多变量逻辑回归控制表明,接受肌腱固定术的患者不太可能再次入院(调整后的比值比[AOR]:0.42,95%置信区间[CI]:0.17-0.98,P=0.050)或维持严重不良事件(AOR:0.27,95%CI:0.13-0.57,P<.001),但同样可能发生轻微不良事件(AOR:0.87,CI:0.21-3.68,P=.850),与接受肌腱切开术的患者相比。最后,比较2012-2021年的使用率,发现与开放性肌腱固定术(从41.0%到57.3%)和关节镜下肌腱固定术(52.8%到41.64%;P趋势=.001)相比,肌腱切开术的比例显著下降(从6.2%到1.0%).
    据我们所知,这是第一个大型国家数据库研究,调查二头肌长头肌腱病变的各种手术治疗之间的术后并发症发生率。我们的结果表明,肌腱固定术产生的严重不良事件较少,再入院率低于肌腱切开术。我们还发现肌腱切开术的手术时间较短。这些发现支持近年来肌腱固定术相对于肌腱切开术的使用增加。
    UNASSIGNED: While studies have assessed comparative rates of restoration of shoulder function and alleviation of symptoms, comparative systemic postoperative complication rates between biceps tenotomy and tenodesis have yet to be assessed. The purpose of the present study was to use a national administrative database to perform a comprehensive investigation into 30-day complication rates after biceps tenotomy versus tenodesis, thus providing valuable insights for informed decision-making by clinicians and patients regarding the optimal surgical approach for pathologies of the long head of the biceps tendon.
    UNASSIGNED: The National Surgical Quality Improvement Program database was queried to analyze postoperative complication rates and metrics associated with biceps tenotomy and tenodesis. Patient data spanning from 2012 to 2021 was extracted, with relevant variables assessed to identify and compare these two surgical approaches. Adjusted and unadjusted analyses were utilized to analyze patient demographics, comorbidities, operative times, lengths of stay, readmissions, adverse events, and yearly surgical volume, along with trends in usage, across cohorts.
    UNASSIGNED: Of 11,527 total patients, 264 (2.29%), 6826 (59.22%), and 4437 (38.49%) underwent tenotomy, tenodesis with open repair, and tenodesis with arthroscopic repair, respectively. Tenotomy operative times ([mean ± SD]: 66.25 ± 44.76 minutes) were shorter than those for open tenodesis (78.83 ± 41.82) and arthroscopic tenodesis (75.98 ± 40.16). Conversely, tenotomy patients had longer hospital days (0.88 ± 4.86 days) relative to open tenodesis (.08 ± 1.55) and arthroscopic tenodesis (.12 ± 2.70). Multivariable logistic regression controlling for demographics and comorbidities demonstrated that patients undergoing tenodesis were less likely to be readmitted (adjusted odds ratio [AOR]: 0.42, 95% confidence interval [CI]: 0.17-0.98, P = .050) or sustain serious adverse events (AOR: 0.27, 95% CI: 0.13-0.57, P < .001), but equally likely to sustain minor adverse events (AOR: 0.87, CI: 0.21-3.68, P = .850), compared with patients undergoing tenotomy. Lastly, comparing utilization rates from 2012 to 2021 revealed a significant decrease in the proportion of tenotomy (from 6.2% to 1.0%) compared to open tenodesis (from 41.0% to 57.3%) and arthroscopic tenodesis (52.8% to 41.64%; P trend = .001).
    UNASSIGNED: To our knowledge, this is the first large national database study investigating postoperative complication rates between the various surgical treatments for pathologies of the long head of the biceps tendon. Our results suggest that tenodesis yields fewer serious adverse events and lower readmission rates than tenotomy. We also found a shorter operative time for tenotomy. These findings support the increased utilization of tenodesis relative to tenotomy in recent years.

    特发性马蹄内翻足常见于1/1000的儿童。皮拉尼计分系统,包括足中挛缩评分和足后挛缩评分,传统上用于评估马蹄内翻足畸形的严重程度。Ponseti协议用于马蹄内翻足畸形的治疗。该研究旨在使用Ponseti方案评估马蹄内翻足治疗的结果,并将结果与最初的Pirani评分相关联。
    82名1周至2岁有128名特发性马蹄足的儿童被纳入研究。在招募时使用Pirani评分系统对马蹄内翻足畸形的严重程度进行评分。根据Ponseti方案,每周进行连续操作和石膏应用,无论是否进行跟腱肌腱切开术。
    平均初始皮拉尼评分为3.6±0.9。使用的平均模型数为5.9±1.3(范围:4-9个模型)。在51.56%的足部进行了肌切开术。与“无肌腱切开术”组相比,需要进行肌腱切开术的组需要更多的管模,因此需要更长的治疗时间。顺服组的足部复发率为2%,而不符合使用足外展支具的组的复发率为69%.随访6个月成功率为84.4%。
    Ponseti方案是治疗特发性马蹄内翻足的极好方法,Pirani评分系统可用于评估初始严重程度和结局.最初的皮拉尼评分与治疗持续时间相关。
    UNASSIGNED: Idiopathic clubfoot occurs commonly in children with a prevalence of 1 in 1000. The Pirani scoring system, which consists of a midfoot contracture score and hindfoot contracture score, is traditionally used in assessing the severity of clubfoot deformity. Ponseti protocol is used in the management of clubfoot deformity. The study aimed to evaluate the outcome of the management of clubfoot using the Ponseti protocol and to correlate the outcome with the initial Pirani score.
    UNASSIGNED: Eighty-two children aged 1 week-2 years with 128 idiopathic clubfeet were recruited into the study. The severity of their clubfoot deformities was scored using the Pirani scoring system on recruitment. They were managed with weekly serial manipulation and cast application with or without tendon-Achilles tenotomy according to Ponseti protocol.
    UNASSIGNED: The average initial Pirani score was 3.6 ± 0.9. The average number of casts used was 5.9 ± 1.3 (range: 4-9 casts). Tenotomy was done in 51.56% of the feet. The group that required tenotomy required more casts and as such longer duration of treatment than the \"no tenotomy\" group. There was a relapse rate of 2% in the feet of the compliant group, whereas the relapse rate was 69% in the group that was not compliant with the use of foot-abduction brace. The success rate at 6 months follow-up was 84.4%.
    UNASSIGNED: Ponseti protocol is an excellent method of management of idiopathic clubfoot, and the Pirani scoring system was useful in assessing the initial severity and the outcome. The initial Pirani score correlates with the duration of treatment.

    超声(US)可以指导和确认马蹄内翻足跟腱的经皮释放。然而,这种技术可能并不总是可用的;因此,外科医生报告了肌腱释放的感觉(\"点击\"或\"pop\")和汤普森标志可以证明他们是敏感和可靠的确认肌腱完全释放。这项研究的目的是比较旨在检测外科医生报告的“点击”或“流行”感觉的临床操作的可重复性,以及在经皮跟腱切开术中手术释放后的汤普森体征与US患者相比。对特发性马蹄内翻足的连续患者进行了横断面可重复性研究。所有患者均计划在镇静下使用标准的经皮跟腱切开术在手术室进行腱切开术。将外科医生报告的手术感觉(\“click\”或\“pop\”)和汤普森体征与美国对切口的评估进行比较。最终的Pirani评分用于预测复发风险,并与石膏模型的数量和年龄相关。30名患者的45英尺受到影响。18名(60%)男性。年龄范围:1至60个月。记录了38名患者的“点击”或“流行”的感觉,美国确认了37例患者的完全释放,灵敏度(Se)为0.95,特异性(Sp)为0.63。在2次评估中,33例和36例患者的Thompson体征均为阳性,Se值分别为0.87和0.92,Sp值分别为0.88和0.75。皮拉尼的最终比分,复发风险的预测因子,曲线下面积为0.80(95%CI=0.63-0.97;P=0.005),Se=0.78,并且Sp=0.56,具有2.75的截止点。跟腱松解感和Thompson征有较高的敏感性,患病率,准确度,和后测概率。根据临床体征确认肌腱释放可能会阻止US的使用。
    Ultrasound (US) can guide and confirm percutaneous release of the achilles tendon in the clubfoot. However, this technique may not always be available; therefore, surgeons\' reported feelings of tendon release (\"click\" or \"pop\") and the Thompson sign could demonstrate that they are sensitive and reliable for confirming complete tendon release. The purpose of this study was to compare the reproducibility of clinical maneuvers that aim to detect the reported \"click\" or \"pop\" sensation by the surgeon and the Thompson sign after surgical release in percutaneous achilles tenotomy compare with US in patients with clubfoot. A cross-sectional reproducibility study of consecutive patients with idiopathic clubfoot was conducted. All the patients were scheduled to undergo tenotomy in the operating room using the standard percutaneous achilles tenotomy technique under sedation. The surgeon\'s reported surgical sensation (\"click\" or \"pop\") and Thompson signs were compared to the US assessment of the cut. The final Pirani score was used to predict recurrence risk and was correlated with the number of plaster casts and age. Forty-five feet were affected in 30 patients. Eighteen (60%) men. Age range: 1 to 60 months. The sensation of \"click\" or \"pop\" was recorded in 38 patients, and complete release was confirmed by US in 37 patients, for a sensitivity (Se) of 0.95 and specificity (Sp) of 0.63. Thompson signs were positive in 33 and 36 patients at 2 evaluations, with Se values of 0.87 and 0.92 and Sp values of 0.88 and 0.75, respectively. The Pirani final score, a predictor of recurrence risk, had an area under the curve of 0.80 (95% CI = 0.63-0.97; P = .005), Se = 0.78, and Sp = 0.56, with a cutoff point of 2.75. The feeling of achilles tendon release and Thompson sign had high sensitivity, prevalence, accuracy, and posttest probability. The confirmation of tendon release based on clinical signs could prevent the use of US.

    背景:治疗马蹄内翻足的Ponseti方法包括采用连续铸造的初始治疗,并在需要时进行achlototenaction切开术,接下来是维持阶段,包括用足外展矫形器(FAO)治疗至少四年。本研究旨在检查持续时间,当然,和儿童马蹄内翻足矫形治疗的结果。
    方法:321名马蹄内翻足儿童,出生于2015年至2017年,在瑞典小儿骨科质量登记册(SPOQ)中注册,纳入这项前瞻性队列研究。提取有关畸形特征和矫形治疗的数据。对于患有双侧马蹄内翻足的儿童,分析中包括一只脚.
    结果:在288名患有孤立性马蹄内翻足的儿童中,274名儿童(95.5%)接受了粮农组织的处方,100名儿童(35%)在4岁之前改变了矫形器类型。在33名非孤立马蹄内翻足的儿童中,25名儿童(76%)被指定为粮农组织,21名儿童(64%)在4岁之前改变了矫形器类型。220名孤立性马蹄内翻足的儿童(76%),28名非孤立性马蹄内翻足的儿童(84%)继续矫形治疗,直到4岁或更长时间。在患有孤立马蹄内翻足的儿童中,在4岁之前结束矫正治疗的儿童(n=63)出生时的皮拉尼评分低于在4岁/4岁之后结束矫正治疗的儿童(n=219)(p=0.01).在4岁之前结束矫形治疗的儿童中,改变矫形器类型更为常见(p=0.031)。
    结论:瑞典大多数马蹄内翻足患儿在维持阶段接受FAO治疗。在4岁之前结束矫形治疗的儿童中,改变矫形器类型的儿童比例显着增加,诊断时的皮拉尼评分显着降低。有必要进行长期随访研究,以充分了解如何优化,个性化,关于足部受累和畸形严重程度的矫形治疗。

    BACKGROUND: The Ponseti method for treating clubfoot consists of initial treatment with serial casting accompanied by achillotenotomy if needed, followed by the maintenance phase including treatment with a foot abduction orthosis (FAO) for at least four years. This study aimed to examine the duration, course, and outcome of orthotic treatment in children with clubfoot.
    METHODS: 321 children with clubfoot, born between 2015 and 2017, registered in the Swedish Pediatric Orthopedic Quality Register (SPOQ), were included in this prospective cohort study. Data on deformity characteristics and orthotic treatment were extracted. For children with bilateral clubfoot, one foot was included in the analysis.
    RESULTS: Of the 288 children with isolated clubfoot, 274 children (95.5%) were prescribed an FAO, and 100 children (35%) changed orthosis type before 4 years of age. Of the 33 children with non-isolated clubfoot, 25 children (76%) were prescribed an FAO, and 21 children (64%) changed orthosis type before 4 years of age. 220 children with isolated clubfoot (76%), and 28 children with non-isolated clubfoot (84%) continued orthotic treatment until 4 years of age or longer. Among children with isolated clubfoot, children ending orthotic treatment before 4 years of age (n = 63) had lower Pirani scores at birth compared to children ending orthotic treatment at/after 4 years of age (n = 219) (p = 0.01). It was more common to change orthosis type among children ending orthotic treatment before 4 years of age (p = 0.031).
    CONCLUSIONS: The majority of children with clubfoot in Sweden are treated with an FAO during the maintenance phase. The proportion of children changing orthosis type was significantly greater and the Pirani score at diagnosis was lower significantly among children ending orthotic treatment before 4 years of age. Long-term follow-up studies are warranted to fully understand how to optimize, and individualize, orthotic treatment with respect to foot involvement and severity of deformity.

    大黄蜂,也被称为先天性马蹄内翻足是一种普遍的儿童疾病,如果不治疗,会导致长期的不适和损害。Ponseti技术,旨在实现正确的脚部定位,被广泛接受。这项研究调查了马蹄内翻足严重程度(皮拉尼评分)的影响,患者年龄,以及有效治疗所需的铸件总数的初始操作和铸件重量。
    进行了一项前瞻性研究,涉及40例特发性马蹄内翻足患者,根据Ponseti方法进行了操作和铸造。患者年龄,体重,和脚皮拉尼评分评估了实现70°外展所需的模型总数。
    大多数参与者是4-6个月的男性婴儿,中位年龄为4.5个月。其中一半在第一次就诊时体重在3.00至4.99公斤之间,平均体重为3.20公斤。双侧马蹄内翻足受累很常见(57.5%)。PiraniHFCS2.0-3患儿通常需要经皮张力切开术(87.5%,P值0.05)。平均而言,患者需要5个管型(范围3-9)。平均皮拉尼总分右脚为4.71,左脚为4.61。该研究报告了较高的皮拉尼总分与所需的演员数之间呈正相关。
    Pirani评分系统在评估马蹄足严重程度和预测治疗成功方面非常准确。它是铸型总数和经皮肌腱切开术需求的唯一最重要的预测指标。
    UNASSIGNED: Clubfoot, also known as congenital talipes equinovarus is a prevalent childhood ailment that, if untreated, can lead to long-term discomfort and impairment. The Ponseti technique, aimed at achieving corrected foot positioning, is widely accepted. This study investigated the influence of clubfoot severity (Pirani score), patient age, and initial manipulation and casting weight on the overall number of casts needed for effective treatment.
    UNASSIGNED: A prospective study was carried out involving 40 idiopathic clubfoot patients where manipulation and casting were performed following the Ponseti method. Patient age, weight, and foot Pirani score were evaluated concerning the total number of casts needed to achieve 70° of abduction.
    UNASSIGNED: The majority of participants were male infants aged 4-6 months, with a median age of 4.5 months. Half of them weighed between 3.00 and 4.99 kg at their first hospital visit, with a median weight of 3.20 kg. Bilateral clubfoot involvement was common (57.5%). Children with Pirani HFCS 2.0-3 often required percutaneous tenotomy (87.5%, p value 0.05). On average, patients needed 5 casts (range 3-9). The mean total Pirani scores were 4.71 for the right foot and 4.61 for the left foot. The study reported a positive correlation between higher total Pirani scores and the required number of casts.
    UNASSIGNED: The Pirani scoring system is highly accurate in assessing clubfoot severity and predicting treatment success. It emerged as the single most significant predictor for both the total number of casts and the need for percutaneous tenotomy.

    背景:马蹄内翻足是一种常见的先天性畸形。Ponseti技术,包括早期矫正操作,然后应用长腿铸型和跟腱切开术,被广泛接受为首选治疗。手术后肌腱快速愈合已有文献记载,但是关于长期肌腱结构和特性的方面尚不清楚。文献中已经描述了三例先前接受过马蹄内翻足治疗的青少年跟腱断裂。由于破裂在这个年龄段是罕见的事件,有人推测可能与以前的手术相关.该研究的主要目的是比较接受马蹄内翻足治疗的患者跟腱的超声检查结果,仅接受铸造治疗的患者和接受手术(经皮肌腱切开术或Z形成形术延长术)的患者之间的差异。
    方法:有22名无症状患者(34英尺),中位年龄为12岁,以前治疗过马蹄内翻足,本研究招募的患者;患者在随访门诊期间接受了跟腱超声检查。
    结果:与单独使用石膏治疗的肌腱相比,随着手术肌腱的低回声区域的存在,观察到更大的厚度和更多的结构改变(p值:分别为0.0498和<0.001)。这些超声发现表明肌腱疼痛,如在肌腱病中看到的。
    结论:无症状马蹄足手术患者存在超声改变,需要仔细控制肌腱病的外在因素,以降低皮下破裂的风险。
    BACKGROUND: Clubfoot is a common congenital deformity. The Ponseti technique, involving early corrective manipulations followed by applying long leg casts and Achilles tenotomy, is widely accepted as the preferred treatment. Rapid tendon healing after surgery has been documented, but the aspect regarding long-term tendon structure and properties is not known. Three cases of Achilles tendon rupture in adolescents previously treated for clubfoot have been described in the literature. As rupture is a rare event in this age group, a possible correlation with previous surgery has been hypothesized. The primary aim of the study was to compare the ultrasound findings of the Achilles tendon in patients treated for clubfoot, between patients treated with casting alone and with patients who underwent surgery (percutaneous tenotomy or Z-plasty lengthening).
    METHODS: There were 22 asymptomatic patients (34 feet) with a median age of 12 years, previously treated for clubfoot, that were recruited for this study; the patients underwent an Achilles tendon ultrasound examination during a follow-up outpatient visit.
    RESULTS: A greater thickness and increased number of structural alterations with the presence of hypoechoic areas of the operated tendons compared with those treated with plaster alone were observed (p-value: 0.0498 and <0.001, respectively). These ultrasound findings were indicative of tendon suffering, as seen in tendinopathies.
    CONCLUSIONS: The presence of ultrasound alterations in asymptomatic patients operated on for clubfoot requires careful control of the extrinsic factors of tendinopathy in order to reduce the risk of subcutaneous rupture.

    背景:在肩部手术中经常进行二头肌肌腱长头的肌腱固定术,和全缝合锚钉作为固定方法变得越来越流行。然而,关于全缝线锚钉的最终失效载荷和皮质肱骨插入点的最佳插入角度仍然存在不确定性。
    目的:本研究的目的是比较经常用于肱二头肌肌腱固定术的三种类型的全缝合锚钉的生物力学特性。此外,在猪肱骨模型中观察到两种不同插入角度的影响。
    方法:三种类型的全缝线锚钉的极限失效载荷和失效模式(1.6FiberTak®,1.9FiberTak®,2.6FiberTak®,在12只新鲜冷冻的猪肱骨中以90°和45°的插入角度评估了适用于胸肌下二头肌肌腱固定术的Arthrex®)。锚固件以随机方式在沿着二头肌沟的三个不同插入部位均匀交替插入,并且将缝合线带围绕杆打结以进行拔出测试。总的来说,在通用试验机(Zwick&Roell)中评估了36个锚。
    结果:与1.9FiberTak®(677.8N±57.7N;426.3N±167.0N)相比,2.6FiberTak®在90°插入角(944.0N±169.7N;537.0N±308.8N)下显示出更高的极限失效载荷,p值:0.0080)和1.6FiberTak®(733.0N±67.6N;450.0N±155.8N,p值:0.0018)。所有类型的锚在90°插入角下比在45°插入角下显示出明显更高的极限破坏载荷和更小的标准偏差。主要失效模式是锚杆拔出。只有2.6FiberTak®锚在以90°插入角度放置时显示缝合线断裂作为主要失效模式。
    结论:所有三种全缝合锚钉都是适用于胸肱二头肌下肌腱固定术的固定方法。关于我们的数据,我们建议90°作为最佳插入角度。
    结论:外科医生应了解锚钉尺寸和全缝线锚钉插入角度的影响,以优化最终失效载荷并实现牢固固定。
    BACKGROUND: Tenodesis of the long head of the biceps tendon is frequently performed in shoulder surgery, and all-suture anchors have become more popular as fixation methods. However, uncertainty still exists regarding the ultimate load to failure of all-suture anchors and the best insertion angle at a cortical humeral insertion point.
    OBJECTIVE: The purpose of this study was to compare the biomechanical characteristics of three types of all-suture anchors frequently used for biceps tenodesis. In addition, the influence of two different insertion angles was observed in a porcine humeri model.
    METHODS: The ultimate load to failure and failure mode of three types of all-suture anchors (1.6 FiberTak®, 1.9 FiberTak®, 2.6 FiberTak®, Arthrex®) applicable for subpectoral biceps tenodesis were evaluated at 90° and 45° insertion angles in 12 fresh-frozen porcine humeri. The anchors were inserted equally alternated in a randomized manner at three different insertion sites along the bicipital groove, and the suture tapes were knotted around a rod for pullout testing. In total, 36 anchors were evaluated in a universal testing machine (Zwick & Roell).
    RESULTS: The 2.6 FiberTak® shows higher ultimate loads to failure with a 90° insertion angle (944.0 N ± 169.7 N; 537.0 N ± 308.8 N) compared to the 1.9 FiberTak® (677.8 N ± 57.7 N; 426.3 N ± 167.0 N, p-value: 0.0080) and 1.6 FiberTak® (733.0 N ± 67.6 N; 450.0 N ± 155.8 N, p-value: 0.0018). All anchor types show significantly higher ultimate loads to failure and smaller standard deviations at the 90° insertion angle than at the 45° insertion angle. The major failure mode was anchor pullout. Only the 2.6 FiberTak® anchors showed suture breakage as the major failure mode when placed with a 90° insertion angle.
    CONCLUSIONS: All three all-suture anchors are suitable fixation methods for subpectoral biceps tenodesis. Regarding our data, we recommend 90° as the optimum insertion angle.
    CONCLUSIONS: The influence of anchor size and insertion angle of an all-suture anchor should be known by the surgeon for optimizing ultimate loads to failure and for achieving a secure fixation.

    异位骨化(HO),软组织如肌腱和肌肉内骨的病理形成,是严重损伤引起的明显并发症。虽然软组织损伤是HO发育所必需的,创伤诱导HO的具体分子病理学仍是个谜.先前的研究在肌腱HO的早期阶段检测到异常的自噬功能。然而,自噬是否支配HO产生过程尚待确定。这里,采用创伤诱导肌腱HO模型研究自噬与肌腱钙化的关系。在肌腱切开术的早期阶段,据观察,自噬通量显著受损,阻断自噬通量促进了更猖獗的钙化的发展。此外,Gt(ROSA)26sor转基因小鼠模型实验揭示了溶酶体酸功能障碍是自噬通量受损的主要原因。刺激V-ATPase活性恢复溶酶体酸功能和自噬通量,从而逆转肌腱HO。本研究表明,自噬-溶酶体功能障碍在肌腱损伤阶段引发HO,对HO具有潜在的治疗靶向意义。
    Heterotopic ossification (HO), the pathological formation of bone within soft tissues such as tendon and muscle, is a notable complication resulting from severe injury. While soft tissue injury is necessary for HO development, the specific molecular pathology responsible for trauma-induced HO remains a mystery. The previous study detected abnormal autophagy function in the early stages of tendon HO. Nevertheless, it remains to be determined whether autophagy governs the process of HO generation. Here, trauma-induced tendon HO model is used to investigate the relationship between autophagy and tendon calcification. In the early stages of tenotomy, it is observed that autophagic flux is significantly impaired and that blocking autophagic flux promoted the development of more rampant calcification. Moreover, Gt(ROSA)26sor transgenic mouse model experiments disclosed lysosomal acid dysfunction as chief reason behind impaired autophagic flux. Stimulating V-ATPase activity reinstated both lysosomal acid functioning and autophagic flux, thereby reversing tendon HO. This present study demonstrates that autophagy-lysosomal dysfunction triggers HO in the stages of tendon injury, with potential therapeutic targeting implications for HO.

    这项回顾性观察性研究评估了两种不同手术方法治疗冻结肩(粘连性囊炎)的疗效。本研究旨在比较疗效,安全,2种治疗方式的恢复时间。该研究包括50例诊断为肩周炎并在Seyhan州立医院接受治疗的患者。根据所接受的治疗将患者回顾性分为2组。第1组包括25名患者,他们在麻醉下接受了标准的封闭操作,一种涉及肩关节被动运动以撕裂紧实的囊并扩大运动范围(ROM)的技术。第2组,包括25名患者,除了开放囊切除术和肱二头肌肌腱囊松解术外,还接受了闭合操作。开放性囊切除术包括手术切除囊以减轻炎症,二头肌肌腱胶囊释放通过部分去除肌腱胶囊来解决慢性二头肌肌腱炎。人口统计信息数据,操作细节,术前和术后情况,收集并分析患者报告的结局.数据分析显示,闭合手法与开放囊切除术和肱二头肌肌腱囊松解术相结合更有效地减轻疼痛,增加ROM,和提高生活质量比单独封闭操作。讨论通常会详细说明结果与现有文献的比较,临床意义,以及该研究的任何潜在限制。结果表明,密闭式手法结合开放囊切除术和肱二头肌肌腱囊松解术在减轻疼痛方面优于单独的密闭式手法,增加ROM,提高生活质量。
    This retrospective observational study evaluated the efficacy of 2 different surgical approaches for the treatment of frozen shoulder (adhesive capsulitis). This study aimed to compare the efficacy, safety, and recovery times of the 2 treatment modalities. Fifty patients diagnosed with frozen shoulder and treated at Seyhan State Hospital were included in the study. The patients were retrospectively divided into 2 groups based on the treatment received. Group 1 consisted of 25 patients who underwent standard closed manipulation under anesthesia, a technique involving passive movements of the shoulder joint to tear the tight capsule and expand the range of motion (ROM). Group 2, which included 25 patients, underwent closed manipulation in addition to open bursectomy and biceps tendon capsule release. Open bursectomy involves surgical removal of the bursa to alleviate inflammation, while biceps tendon capsule release addresses chronic biceps tendonitis by partially removing the capsule of the tendon. Data on demographic information, operative details, preoperative and postoperative conditions, and patient-reported outcomes were collected and analyzed. Data analysis revealed that the combination of closed manipulation with open bursectomy and biceps tendon capsule release was more effective in reducing pain, increasing ROM, and improving quality of life than closed manipulation alone. The discussion would typically elaborate on how the results compare with existing literature, the clinical implications, and any potential limitations of the study. The results showed that the method that combined closed manipulation with open bursectomy and biceps tendon capsule release was better than closed manipulation alone in terms of reducing pain, increasing ROM, and improving quality of life.
