The extended flexor carpi radialis approach for partially healed malaligned fractures of the distal radius

Abstract Purpose The aim of the study is to evaluate the safety and utility of the extended flexor carpi radialis (FCR) exposure and volar locking plate fixation for partially healed malaligned fractures of distal radius. Materials and methods Thirty-five patients with a partially healed malaligned fracture of the distal radius had realignment of the fracture using an extended FCR approach (release of the insertion of the brachioradialis and dorsal periosteum) and volar locked plate and screw fixation. Results Retrospective review an average of 20 months after the index operation patients identified an average wrist extension of 68°, flexion of 64°, pronation of 84° and supination of 85°. Radial inclination, volar tilt and ulnar variance significantly improved compared to preoperative radiographs. All fractures healed, and there were no infections, implant loosening or breakage or tendon ruptures. Conclusions This study demonstrated that the extended FCR approach is safe and effective as a treatment method for nascent malunions of the distal radius.
