The incidence and location of heterotopic bone formation following total shoulder arthroplasty were evaluated in 58 Neer Mark-II total shoulder replacements. One year after surgery, 45% had developed some ectopic ossification. In six shoulders (10%) the ossifications roentgenographically bridged the glenohumeral and/or the glenoacromial space. There was no correlation between shoulder pain and the development of ossification. Shoulders with grade III heterotopic bone formation had a limited range of active elevation compared with shoulders without or with only a milder lesion. Men and patients with osteoarthritis of the shoulder joint were significantly disposed to the development of heterotopic bone. Heterotopic bone formation following total shoulder arthroplasty is frequent, but disabling heterotopic ossifications seem to be rare.
对58例Neer II型全肩关节置换术患者进行评估，以确定全肩关节置换术后异位骨形成的发生率和位置。术后1年，45%的患者出现了一些异位骨化。在6例（10%）肩部，X线显示骨化连接了盂肱关节和/或盂肩峰间隙。肩部疼痛与骨化的发生之间没有相关性。与没有或仅有较轻病变的肩部相比，III级异位骨形成的肩部主动抬高范围受限。男性和患有肩关节骨关节炎的患者异位骨形成的倾向明显更高。全肩关节置换术后异位骨形成很常见，但致残性异位骨化似乎很少见。
