肩关节镜下缝线锚钉修复合并关节盂唇前后延伸撕裂的严重SLAP损伤

目的探讨肩关节镜下缝线锚钉修复合并关节盂唇上部从前到后的损伤（SLAP）的疗效。方法 2007年至2009年,结合体格检查、MRI和关节镜诊断为关节盂唇前后沿伸撕裂的SLAP损伤患者12例,关节镜下采用缝线锚钉治疗。其中SLAP-Ⅴ型损伤（Bankart损伤＋SLAPⅡ型损伤）7例,SLAP-Ⅷ型损伤（SLAPⅡ型损伤合并后下方盂唇撕裂）3例以及一种新的SLAP损伤类型2例,即SLAPⅢ型损伤＋前后盂唇撕裂并脱位。术前及术后随访采用ASES评分及Constant-Murley功能评估。结果所有患者平均随访27个月。术前及终末随访ASES评分为（77.4±3.7）分vs（94.3±2.6）分,两者比较差异有统计学意义（t=28.1,P〈0.05）;Constant-Murley评分为（78.1±4.6）对（93.9±3.7）分（t=28.9,P〈0.05）。术后无一例患者发现再脱位,且均重返伤前工作岗位。结论随着肩关节镜技术的不断进步,肩关节盂唇严重损伤的修复更加有效、微创及简便。

Arthroscopic capsulolabral reconstruction of the severe superior labrum anterior-posterior lesion with anterior or/and posterior extensive tear

Objective To investigate the efficacy of arthroscopic capsulolabral reconstruction of the severe superior labrum anterior posterior (SLAP) lesion with anterior or/and posterior extensive tear. Methods From 2007 to 2009, 12 shoulders in 12 patients were diagnosed as SLAP lesion with anterior or/ and posterior extensive tear by physical examination, magnetic resonance image and arthroscopy. Seven cases were Type Ⅴ SLAP lesion described as a superior labral tear confluent with an anterior-inferior labral tear, or Bankart lesion. Three cases were Type Ⅷ SLAP lesion described as an avulsion of the biceps anchor (type Ⅱ SLAP) with extensive labral tear posteriorly along the glenoid. Two cases were a new type of SLAP lesion described by us as a bucket-handle tear of superior labrum with extensive labral tear posteriorly along the glenoid with a normal biceps tendon and an intact biceps anchor, while the avulsed labrum was dislocated. All cases were treated with an arthroscopic capsulolabral reconstruction. Shoulders were evaluated preoperatively and postoperatively by the American Shoulder and Elbow Surgeons (ASES) scoring system and standard subjective scales for stability, strength, function, and range of motion. Results 12 shoulders were analyzed at a mean follow-up time of 27 months. The mean ASES score improved from 77.4 to 94.3 (t=28.1, P<0.05). There were significant improvements in stability, pain, function, and range of motion based on standardized subjective scales (t=28.9, P<0.05). No shoulder required revision surgery for recurrent instability. All patients were able to return to job. Conclusions Arthroscopic capsulolabral reconstruction is an effective and reliable treatment for glenohumeral instability due to severe complex SLAP lesions. Successful return to sport is a reasonable expectation.
