Combined Plating of Intra-Articular Distal Radius Fractures, a Consecutive Series of 74 Cases

Background The distal radius fracture (DRF) is themost common fracture in adults. For unstable intra- articular fractures, the choice of treatment is often operative. The optimal choice of fixation remains a matter of discussion. Question/Purpose Can combined volar and dorsal plating, using a dorsal frame plate, achieve a good functional and radiographic 1-year outcome in intra-articular DRFs? Methods In a retrospective cohort study, we evaluated 74 consecutive patients operated with combined plating using a volar plate and a dorsal frame plate. The DRFs were operated between 2016 and 2017 and all cases were AO type C intraarticular fractures. The primary outcome was patient- reported outcome measures including radiographic examination 1 year postoperatively. Secondary outcome measures included wrist range of motion, visual analog scale (VAS) pain scores, and hand grip strength. Results The median patient-rated wrist evaluation score was 18 points; the quick disabilities of the arm, shoulder, and hand score was 14.8 points. The median Batra radiographic score was 88. Wrist extension was 76% of the uninjured side, flexion was 74%, pronation was 94%, and supination was 94%. VAS pain scores were 0 at rest and 2 during activity. Hand grip strength was 82% compared with the uninjured side. The radiographic outcome according to Batra did not correspond to the patient-reported outcome. Patients older than 60 years had significantly better QuickDASH (quick disabilities of the arm, shoulder, and hand) and PRWE scores (patient-rated wrist evaluation scores) and less pain during activity compared with younger patients despite similar radiographic outcome. There were no tendon ruptures; hardware removal was performed in 21 of the 74 patients. Conclusion The radiographic outcome did not correspond to the functional outcome 1 year postoperatively. Older patients report less pain and better functional outcome compared with younger patients. There were no tendon ruptures and the frequency of hardware removal was acceptable. Complex intra-articular DRFs AO type C can be managedwith volar and dorsal frame-plate fixation to restore distal radius anatomy and achieve a good functional outcome.
