METHODS: In this prospective randomized study, 20 patients underwent proximal row carpectomy or four-corner fusion to treat wrist arthritis and their functional results were compared. The midcarpal joint was free of lesions in all patients. RESULTS: Both proximal row carpectomy and four-corner fusion reduced the pain. All patients had a decreased range of motion after surgery. The differences between groups were not statistically significant. CONCLUSIONS: Functional results of the two procedures were similar as both reduced pain in patients with scapholunate advanced collapse/scaphoid non-union advanced collapse (SLAC/SNAC) wrist without degenerative changes in the midcarpal joint.engopenAccessArthritisDegenerativeWrist injuriesCarpal bonesArthrodesisWrist jointscapholunate advanced collapsescaphoid nonunionslac-wristintercarpal arthrodesisdegenerative arthritismidcarpal arthrodesissnac-wristexcisionarticleCopyright HOSPITAL CLINICAS, UNIV SAO PAULO10.1590/S1807-59322011000100010Medicine, General & Internal
