Minimal invasive screw fixation and early mobilization of acute scaphoid fractures in the middle third: operative technique and early functional outcome.
Fractures of the scaphoid are relatively common injuries. Differentiation between stable and unstable fractures (Herbert classification) cannot always be made with conventional radiographs and should be additionally evaluated by computed tomographic scan. Under most circumstances, minimal invasive surgery with cannulated screws is currently the treatment of choice. Cast immobilization is not necessary. This article describes the technique of fracture fixation in the middle third of the scaphoid from a palmar approach and early functional outcomes. The outcome assessment included measurement of active range of motion as well as grip strength and the Disability of the Arm, Shoulder and Hand questionnaire as a measurement of activities of daily living. Fifty-four patients with acute scaphoid fractures were treated with minimal invasive screw fixation between April 2001 and January 2005. All patients in this retrospective study received a preoperative computed tomographic scan before surgery. Bony consolidation was found in 52 cases after 6 weeks; 2 patients required reosteosyntheses. The results demonstrate that minimal invasive screw fixation leads to satisfying functional outcomes within a few weeks.
