Combined volar and dorsal plating for complex comminuted distal radial fractures.
PURPOSE
To review outcomes of combined volar and dorsal locked plating for AO type-C3 complex comminuted distal radial fractures.


METHODS
Records of 24 patients aged 17 to 77 (mean, 53.3) years who underwent combined volar and dorsal locked plating for AO type-C3 distal radial fractures with volar and dorsal metaphyseal and intra-articular comminution were reviewed. 21 were closed fractures, and 3 were Gustilo-Anderson type-1 open fractures. Bone union, volar tilt, radial inclination, radial height, range of motion, grip strength, and any complications were assessed by a single hand surgeon.


RESULTS
After a mean follow-up of 17 (range, 14-25) months, the mean palmar flexion was 49º (range, 30º-80º), dorsiflexion was 52º (range, 30º-80º), supination was 86º (range, 60º-90º), pronation was 77º (range, 30º-90º), radial deviation was 16º (range, 5º-30º), and ulnar deviation was 27º (range, 10º-50º). The mean grip strength of the injured hand was 69.2% of the uninjured side. The mean time to radiological union was 3.9 (range, 2.5-6.0) months; no patient had non-union. At the time of union, the mean volar tilt was 5º (-22º-14º), radial inclination was 18.6º (8º-28º), and radial height was 8.5 mm (5.0 mm-13.6 mm). One patient had collapse of the dorsal fragment resulting in a dorsal tilt of 22º and limited (30º) forearm pronation. The severity of dorsal metaphyseal comminution had not been recognised and bone grafting was not performed. The patient also had minor complications of little finger flexor tendon irritation and carpal tunnel syndrome. She underwent implant removal and carpal tunnel release at 8 months. One patient had implant-related extensor digitorum communis irritation. Another patient had non-specific chronic wrist pain, which was resolved at one year. No patient had infection, tendon rupture, or complex regional pain syndrome. Four patients underwent implant removal, including 2 who had no implant-related problems.


CONCLUSION
Combined volar and dorsal plating enables early mobilisation and good outcome for certain complex comminuted distal radial fractures.
