Abstract

Fosbury flop tears (FFTs) are a type of rotator cuff tear characterized by the tendon flipping upon itself and adhering medially. These tears have been observed arthroscopically as either bursal-sided partial-thickness tears (BSPTTs) or full-thickness tears (FTTs), though the mechanism leading to FFTs in these tear types remains unclear. This study aimed to investigate the clinical features, acromial morphology, and treatment outcomes of FFTs, stratifying patients into BSPTT and FTT groups. We included patients with small-to-medium-sized supraspinatus tendon tears who underwent arthroscopic rotator cuff repair (ARCR). Those with BSPTTs were categorized as Group P, and those with FTTs as Group F. Variables such as age, sex, diabetes mellitus status, critical shoulder angle (CSA), lateral acromial angle (LAA), sagittal and coronal acromion morphologies, Japanese Orthopaedic Association (JOA) score, and retear rate were evaluated. Group P consisted of 13 patients, primarily younger males with traumatic tears, while Group F included 40 patients, with a higher proportion of females. There were no significant differences between the groups in CSA, LAA, JOA scores, or retear rates. Both groups had a high prevalence of double-floor type osteophytes in coronal acromial morphology. FFTs were frequently observed in both BSPTTs and FTTs, particularly in patients with double-floor osteophytes. BSPTTs with FFTs may be more common in younger patients with trauma. Overall, ARCR outcomes for FFTs were similar between BSPTTs and FTTs, suggesting similar efficacy in treatment across these tear types.

肩峰形态和病因的综合分析肩袖撕裂在Fosbury翻脱撕裂:部分厚度撕裂与全层撕裂法囊侧。
背翻撕裂(FFTs)是一种肩袖撕裂,其特征是肌腱自身翻转并向内侧粘连。关节镜下观察到这些撕裂为囊侧部分厚度撕裂(bsptt)或全厚度撕裂(FTTs),尽管这些撕裂类型导致fft的机制尚不清楚。本研究旨在探讨FFTs的临床特征、肩峰形态和治疗效果,并将患者分为BSPTT组和FTT组。我们纳入了接受关节镜下肩袖修复术(ARCR)的小到中等大小的棘上肌腱撕裂患者。bsptt组为P组,FTTs组为f组。对年龄、性别、糖尿病状况、临界肩角(CSA)、肩峰外侧角(LAA)、肩峰矢状和冠状形态、日本骨科协会(JOA)评分、复归率等进行评价。P组有13例患者,主要是年轻的男性外伤性撕裂,而F组有40例患者,女性比例较高。两组在CSA、LAA、JOA评分或复发率方面无显著差异。两组在冠状峰形态上均有较高的双层骨赘患病率。在bsptt和FTTs中都经常观察到fft,特别是在双层骨赘患者中。bsptt合并fft可能在年轻的创伤患者中更常见。总体而言,bsptt和FTTs治疗fft的ARCR结果相似,表明这些泪液类型的治疗效果相似。
