A series of 42 total shoulder arthroplasties and four humeral hemiarthroplasties were performed with either the English-McNab or Neer prosthesis. Retrospective follow-up study averaged five years with a three-year minimum. Preoperative diagnoses included rheumatoid arthritis, osteoarthritis, posttraumatic arthritis, rotator cuff arthropathy, avascular necrosis, failed prosthesis, and congenital dislocation. Postoperatively, pain improved in 94% of shoulders, and active range of motion improved an average of 42 degrees in abduction and 47 degrees in forward flexion. Rotator cuff lesions were correlated with poorer postoperative function. Complications developed in four shoulders (9%) and consisted of humeral component protrusions (two shoulders), loosened prosthesis (one shoulder), and unrecognized, preoperative tuberculous infection (one shoulder). Fifteen glenoid components (36%) and six humeral components (13%) developed lucent lines roentgenographically, but only one glenoid component developed migration.
使用英式-麦克纳布（English-McNab）或尼尔（Neer）假体进行了一系列42例全肩关节置换术和4例肱骨半关节置换术。回顾性随访研究平均为期五年，最短为三年。术前诊断包括类风湿性关节炎、骨关节炎、创伤后关节炎、肩袖关节病、缺血性坏死、假体失败和先天性脱位。术后，94%的肩部疼痛得到改善，主动活动范围外展平均改善42度，前屈平均改善47度。肩袖损伤与术后功能较差相关。4例肩部（9%）出现并发症，包括肱骨部件突出（2例肩部）、假体松动（1例肩部）和术前未识别的结核感染（1例肩部）。15个肩胛盂部件（36%）和6个肱骨部件（13%）在X线片上出现透亮线，但只有1个肩胛盂部件发生移位。
