Biomechanical studies have shown that a long, centrally placed screw is favourable in scaphoid fracture fixation. A volar percutaneous transtrapezial approach was developed to facilitate central screw placement. The purpose of this study was to evaluate radiographic changes at the ST-joint at long term follow up in patients where this approach was used. Results were graded with use of the visual analogue scale (VAS) and modified Mayo wrist score. Radiographs of both hands, comprising an anteroposterior, lateral and 45 degrees pronated oblique view were obtained. Degenerative changes at the ST-joint were staged according to the modified Eaton & Glickel classification.Introduction
