Is arthrodesis still a good indication for non-inflammatory arthrosis of the wrist?☆

OBJECTIVE The aim of this study was to objectively and subjectively evaluate wrist function after total arthrodesis, among patients with sequelae of non-inflammatory arthritis who were treated with rigid internal fixation using a DCP plate. METHODS Thirty-two patients with sequelae of non-inflammatory degenerative arthritis were treated using total arthrodesis of the wrist. Of these, two patients were treated with Kirschner wires and four discontinued the treatment, thus leaving 26 patients. The indication for arthrodesis of the wrist was the presence of intracarpal pathological conditions: eight wrists presented sequelae from fractures of the distal radius; 13 had sequelae from fractures of the scaphoid; and five had sequelae from Kienbock's disease. The cases were evaluated using the visual analogue scale (VAS), the muscle strength test, the Jebsen-Taylor functional test and the Buck-Gramcko test. RESULTS It was observed that there were no significant differences at the level of 5%, in the variables of grip strength, VAS, Jebsen-Taylor functional test or Buck-Gramcko/Lohmann test, between the pathological conditions. CONCLUSION Total arthrodesis of the wrist using a plate in the dorsal region was shown to be a safe and efficient technique for patients with different types of pathological arthrosis of the wrist, since it did not cause any important functional incapacity and brought great pain relief.
