Replacement arthroplasty of the ulnar head is indicated primarily for stiffness and pain as a consequence of rheumatoid, degenerative, and posttraumatic arthritis of the distal radioulnar joint. It is also successfully used in the setting of previous failed excisional arthroplasty of the distal ulna. A distal ulnar hemiarthroplasty, which anatomically recreates the native ulnar head by employing an eccentric design, is discussed. The surgical technique includes a dorsal approach and careful repair of the soft tissue stabilizers.
尺骨头置换关节成形术主要适用于因桡尺远侧关节类风湿性、退行性和创伤后关节炎导致的僵硬和疼痛。它也成功应用于先前尺骨远端切除关节成形术失败的情况。本文讨论了一种采用偏心设计在解剖学上重建天然尺骨头的尺骨远端半关节成形术。手术技术包括背侧入路和仔细修复软组织稳定器。
