腕关节神经支切断与假体置换治疗月骨缺血性坏死

目的防止月骨缺血性坏死后腕骨排列进行性紊乱，缓解腕痛，增加握力，改善功能。方法１９９２年１月～１９９７年１月，采用腕关节神经支切断，月骨假体置换术治疗月骨缺血性坏死６例。结果术后随访最短１０个月，最长５４个月，平均随访时间３２个月，优良率８３．３％。结论骨间前、后神经腕关节支切断术联合月骨假体置换术治疗月骨缺血性坏死，术后能获得无痛的关节。腕关节神经支切断联合假体置换是治疗月骨缺血性坏死的一种效果较好的方法

RESECTION OF NERVE OF WRIST COMBINING REPLA CEMENT OF LUNATE WITH BONE CEMENT PROSTHESIS IN TREATMENT OF KIENBOCK'S DISEASE

OBJECTIVE: There are various methods used to treat the Kienbock's disease with various outcomes. This study investigated the effect of combining acrylic lunate prosthesis replacement with resection of articular branches to wrist from anterior and dorsal interosseous nerve. METHODS: From January 1992 to January 1997, six cases were included. All of the patients were in stage III according to Lichtman's classification. Besides replacement of the acrylic lunate prosthesis, segment of the pure sensory branches from anterior and posterior interosseous nerves were resected. RESULTS: Follow-up for 10 to 54 months (an average of 32 months) the pain was relieved in all patients except one. The range of movement of wrists were as followings: The extension of the wrist was 20 to 35 degrees (an average of 26 degrees) and flexion was 20 to 35 degrees (an average of 32 degrees). There was no improvement in radial and ulnar deviation. CONCLUSION: Lunate prosthesis replacement combined with resection of articular branches to wrist resulted in a painless wrist and was a satisfactory method.
