title: Long-term assessment of proximal row carpectomy for chronic perilunate dislocations.
abstract: Twelve patients with chronic stage III or stage IV perilunate dislocations were managed over the past 7 years by proximal row carpectomy. All dislocations were untreated or incompletely reduced for a minimum of 8 weeks after injury. The mean time from injury to definitive treatment was 15 weeks (range, 8 weeks to 6 months). Surgical management was inclusive of a dual dorsal and volar approach. Median nerve decompression, lunate excision, and capsuloligament repair was performed volarly and scaphoid and triquetrum carpectomy was accomplished dorsally. Temporary radio capitate K-wire fixation during early soft tissue healing was uniformly performed. All patients were evaluated at an average postoperative duration of 40 months (range, 28 months to 7 years). Marked relief of wrist pain and median nerve dysesthesias was routinely achieved. Effective wrist range of motion and grip strength were restored. Untreated stage III and IV chronic perilunate dislocation treated by proximal row carpectomy eliminates pain and restores function to a severely injured wrist.
