Occult Interpositional Rotator Cuff - an Extremely Rare Case of Traumatic Rotator Cuff Tear

Traumatic interposition of a rotator cuff tendon in the glenohumeral joint without recognizable glenohumeral dislocation is an unusual complication after shoulder trauma. Here we report the clinical and imaging presentations of a 17-year-old man with trapped rotator cuff tendons in the glenohumeral joint after a bicycle accident. The possible trauma mechanism is also discussed.     

Rotator Cuff Problems Among Top Athletes

A rotator cuff injury can be devastating to a professional athlete's career. In this article, comments from the athletic trainers or physicians of athletes like Jim McMahon give a firsthand view of how pros are treated.     

肩袖破裂的影像诊断

肩袖，又称旋转肌袖，对肩关节起主要的稳定作用。肩袖破裂为肩部疼痛的主要原因之一，但在临床上许多病例往往被误诊为肩周炎，而Ｘ线平片又不能很好地显示肩袖发生的病变。笔者通过对５１例肩痛患者肩关节造影和造影后ＣＴ扫描检查，发现肩袖完全破裂１０例，部分破裂７例。认为，肩关节造影为诊断肩袖破裂的重要方法，ＣＴ肩关节造影不仅能提高诊断正确率，而且能提供更多的病变情况，有利于决定手术和手术方法的选择。     

关节镜下三联松解术结合肩袖修复治疗肩袖损伤合并冻结肩的疗效观察

目的 观察关节镜下三联松解术结合肩袖修复应用于肩袖损伤合并冻结肩患者的疗效。方法 选取2016年6月-2021年6月收治的肩袖损伤合并冻结肩患者60例,随机将其分为对照组和研究组,每组患者30例。对照组予以关节镜下三联松解术治疗,研究组予以关节镜下三联松解术结合肩袖修复治疗。比较两组临床指标、视觉模拟评分法(VAS)、肩关节评分(UCLA)、肩肘外科协会(ASES)评分、临床疗效。结果 研究组患者在术中、术后的临床指标及各项评分均优于对照组;并且研究组的治疗总有效率(93.33%)高于对照组(70.00%),差异突出(P<0.05)。结论 关节镜下三联松解术结合肩袖修复能促进肩袖损伤合并冻结肩患者康复,有效降低术中出血量,减少了患者疼痛感,具有较好的肩关节功能改善。     

Gadolinium MR Arthrography of the Rotator Cuff

Conventional magnetic resonance imaging (MRI) of the rotator cuff has not done well in distinguishing partial-thickness tears from tendonitis or small, full-thickness tears. However, these are important distinctions for orthopedic surgeons who are deciding whether to operate and what type of surgery to perform on a patient with suspect rotator cuff pathology. Gadolinium magnetic resonance arthrography (MRA) involves injecting dilute gadolinium into the shoulder under fluoroscopy. Subsequent multiplanar T1-weighted fat-suppressed fast spin echo combined with T2-weighted fast spin echo and short tau inversion recovery (STIR) produces images that can accurately differentiate absence of tear from partial-thickness tear and from small, full-thickness tear; as a fringe benefit, this combination of sequences can identify the inflammation associated with tendonitis. Furthermore, the technique differentiates articular from bursal surface partial-thickness tears, and it accurately quantitates the size of full-thickness tears to help surgeons choose between arthroscopic versus open surgery.
