Sixty-two patients underwent resection of the distal ulna because of pain or limited motion after wrist trauma. The median length of resection was 23 mm. Injury to the distal radioulnar joint occurred primarily during fractures of the distal radius. Followup time averaged 87 months. The primary surgical indication was pain, but some procedures were performed in an effort to increase motion. All patients improved after surgery. Three patients had residual pain, 25 had mild pain, and 34 had no pain. Supination was greatly improved, with only modest improvement in other wrist motions. Four patients developed ulnar translation of the carpus (from 1 to 3 mm). Pseudoarticulation and ulnar regrowth of the carpus were noted, but neither pseudoarticulation nor regrowth was clinically symptomatic. Grip strength improved significantly after surgery, the average from 45.3 to 78.9% of the unaffected wrist. The presence or absence of radiocarpal arthritis preoperatively had no significant effect on the patients' estimates of results. Overall, 51 patients (82%) had satisfactory results. The primary gains were pain relief, increased supination, and increased strength.
62例患者因腕部创伤后疼痛或活动受限接受了尺骨远端切除术。切除的中位长度为23毫米。桡尺远侧关节损伤主要发生在桡骨远端骨折时。随访时间平均为87个月。主要手术指征是疼痛，但也有一些手术是为了增加活动度而进行的。所有患者术后均有改善。3例患者仍有残留疼痛，25例有轻度疼痛，34例无疼痛。旋后功能明显改善，其他腕关节活动仅略有改善。4例患者出现腕骨尺侧移位（1至3毫米）。观察到腕骨假关节形成和尺侧再生长，但假关节形成和再生长均无临床症状。术后握力显著提高，平均从不影响侧腕关节的45.3%提高到78.9%。术前是否存在桡腕关节炎对患者对结果的评估没有显著影响。总体而言，51例患者（82%）取得了满意的结果。主要收获是疼痛缓解、旋后增加和力量增强。
