总结西南地区军队人员复发性肩关节脱位的临床特征。

根据国际疾病分类编码ICD-10，检索解放军联勤保障部队第九二〇医院病例系统，时间范围：2010年1月1日至2019年12月31日，临床诊断关键词包括：肩关节脱位、复发性肩关节脱位、肩关节盂唇前下方的Bankart损伤、肩关节上盂唇前向后(SLAP)损伤及肩胛盂盂唇损伤。回顾性采集复发性肩关节脱位患者的临床特征：如性别、年龄、首次脱位时间、脱位侧别、首次处理方式、脱位次数、脱位原因、脱位方式、职业性质、合并伤、手术方式，术后康复等。术前及末次随访肩关节各项评分采用配对t检验进行比较。

西南地区军队人员共计815例复发性肩关节脱位，男女比例为6.1 ∶1。脱位年龄以30岁以下为主(77.3%)。左右比例为0.9 ∶1。最常见的脱位方式是前脱位(98.2%)。脱位原因最常见为400 m障碍跑(32.5%)，其次为训练摔伤及撞伤(23.9%)。绝大多数患者初次脱位时采取保守治疗。几乎所有患者均合并有肩关节其他损伤。与术前相比，末次随访时美国肩肘外科医师协会评分(ASES)及肩关节功能Rowe评分明显提高(t＝12.470、42.804，均为P<0.05)。

西南地区军队人员复发性肩关节脱位好发于30岁以下的年轻男性，主要由400 m障碍及训练摔伤、过顶投掷运动引起，以前脱位为主，常常合并有肩关节其他损伤，手术治疗效果良好。

To summarise a clinical characteristics analysis in recurrent shoulder dislocation among military personnel in Southwest China.

According to International Classification of Diseases Code ICD-10, medical record system of the 920th Hospital of Joint Logistics Support Force was searched, from 1st January, 2010 to 31st December, 2019, for the patients with recurrent shoulder dislocation. The included keywords extracted from diagnosis were: shoulder dislocation, recurrent shoulder dislocation, Bankart lesion, injury of the superior labrum anterior and posterior (SLAP) and glenoid labrum lesion. Clinical characteristics of the patients with recurrent shoulder dislocation were collected, including gender, age, first dislocation time, side of dislocation, method of primary treatment, number and cause of dislocation, type of dislocation, occupation, combined injury, surgical treatment and method of rehabilitation. The generally used assessment scores for shoulder before surgery and at the last follow-up were compared by paired t test.

A total of 815 patients who suffered recurrent shoulder dislocation, with a male to female ratio at 6.1 ∶1.0. Majority of patient was under 30 years of age (77.3%). There was a 0.9 ∶1 ratio for left and right dislocation. The anterior shoulder dislocation was the most common dislocation (98.2%). The most common cause of shoulder dislocation was 400m obstacles course training (32.5%), followed by training falls and collisions (23.9%). Most of the patients received a conservative treatment for the first dislocation. Almost all the patients were suffered other injuries of shoulder. Comparing with shoulder conditions before surgery, the scores of the American Shoulder and Elbow Surgeons (ASES) rating scale and Rowe shoulder function scale were significantly improved at the final follow-up, and the difference was statistically significant (t=12.470, 42.804, both P<0.05).

Recurrent shoulder dislocation among servicemen in Southwest China is common in young men under 30 years old. It is mainly caused by 400 m obstacles training, falling and overhead throwing. An anterior dislocation is the main type of shoulder dislocation, and it often combines with other shoulder injuries. Surgical treatment is effective for shoulder dislocation.
