Ulnocarpal abutment or the ulnocarpal impaction syndrome occurs when excessive loads exist between the distal ulna and ulnar carpus. This overloading occurs as a result of the distal ulnar articular surface being more distal than the ulnar articular surface of the distal radius. This situation has been termed positive ulnar variance, and it can quickly lead to ulnar-sided wrist degenerative changes and functional losses. Patients often have vague, ulnar-sided complaints of chronic pain and swelling with an insidious onset that does not correlate with any specific traumatic event. Many procedures have been developed to alleviate this condition, but the gold standard for correcting positive ulnar variance is the ulnar shortening osteotomy. The goals of the shortening procedure are to relieve pain and prevent arthritis by reestablishing a neutral or slightly negative ulnar variance. We describe a new plate and compression system in which an oblique ulnar diaphyseal osteotomy is both completed and stabilized through the same jig-based system.
尺腕撞击或尺腕撞击综合征发生于尺骨远端与尺侧腕骨之间存在过度负荷时。这种过载是由于尺骨远端关节面比桡骨远端的尺侧关节面更靠远端所致。这种情况被称为正尺骨变异，它可迅速导致尺侧腕关节退行性改变和功能丧失。患者常出现尺侧慢性疼痛和肿胀的模糊症状，起病隐匿，与任何特定创伤事件无关。已经开发了许多手术来缓解这种情况，但纠正正尺骨变异的金标准是尺骨短缩截骨术。缩短手术的目标是通过重建中性或轻度负尺骨变异来缓解疼痛并预防关节炎。我们描述了一种新的钢板和加压系统，其中尺骨干斜形截骨术通过同一基于夹具的系统完成并固定。
