    Abstract:
    INTRODUCTION: Optimal fixation for highly comminuted distal radius fractures remains a major treatment challenge for orthopaedic surgeons. Dorsal distraction plating can serve as an improved fixation technique by allowing reduction under ligamentotaxis, providing a dorsal buttress, addressing proximal comminution, and allowing for early weightbearing in polytrauma patients. The aim of this study was to review current literature regarding treatment of distal radius fractures treated with dorsal distraction plating. METHODS: We performed a literature search in Pubmed and EMBASE databases to identify all studies analyzing use of dorsal distraction plating. Case reports, biomechanical and anatomic cadaver studies were excluded from analysis. Primary outcome measures were range of motion (ROM) at final follow up, grip strength, and radiographic parameters. RESULTS: Eight studies were included in the final analysis. Pooled mean ROM after dorsal distraction plating was found to be 47.6° of flexion, 50.5° of extension, 76.0° of pronation, and 74.2° of supination. Pooled mean grip strength was 79.1% compared to the uninjured contralateral limb. Pooled mean volar tilt was 3.6°. Overall radial height was maintained at an average of 10.5 mm with a pooled mean loss of only 3.8 mm in length. Mean radial inclination was found to be 19.4 mm with patients having a mean ulnar variance of 0.5 mm. DISCUSSION & CONCLUSION: Treatment of comminuted intra-articular distal radius fractures with dorsal distraction plating yielded excellent outcomes with very low complication rates, and has several advantages over volar plating and/or external fixation for these fractures. Necessity of plate removal remains a negative feature of this technique.
