Seven men mean age 37 years (range 24-45) who had destroyed metacarpophalangeal joints as a result of pyogenic infection underwent reconstruction of the joint with osseointegrated silicone implants. The interval from infection to reconstruction varied from 5 months to 13 years. At mean follow-up 10 (8-12) years postoperatively the titanium fixtures were all well osseointegrated. The silicone spacer had fractured in one case. The extension lag was 16 (10-20) degrees and the range of movement (ROM) 34 (30-40) degrees. Our data confirm previous observations about the successful long-term osseointegration of titanium fixtures used for the attachment of joint prostheses in the hands of patients with rheumatoid arthritis or osteoarthritis. We conclude that titanium fixtures can be used successfully to fix joint mechanisms for reconstruction of small joints after pyogenous arthritis of the hand and can be used for fixation of joint mechanisms in such cases.
7名平均年龄37岁（范围24 - 45岁）的男性因化脓性感染导致掌指关节破坏，接受了骨整合硅胶植入物的关节重建手术。从感染到重建的间隔时间为5个月至13年。术后平均随访10（8 - 12）年，钛固定装置均实现良好的骨整合。1例硅胶间隔物发生断裂。伸展滞后为16（10 - 20）度，活动范围（ROM）为34（30 - 40）度。我们的数据证实了之前关于钛固定装置在类风湿性关节炎或骨关节炎患者手部成功长期骨整合的观察结果。我们得出结论，钛固定装置可成功用于手部脓性关节炎后小关节重建的关节机构固定，并可用于此类病例的关节机构固定。
