title: Limited arthrodesis for scaphoid nonunion.
abstract: A new surgical technique is described for the treatment of longstanding scaphoid nonunions with established degenerative changes and carpal malalignment. The technique is based on natural history and biomechanical studies and includes the excision of the distal scaphoid fragment and a limited arthrodesis that incorporates the proximal pole of the scaphoid, the lunate, and the capitate. Six men were treated with the procedure for symptomatic chronic scaphoid nonunions, and all limited arthrodeses fused. Pain relief was good to excellent, and range of motion averaged 50% of the contralateral side.
