Percutaneous pinning versus volar locking plate internal fixation for unstable distal radius fractures: a...

This meta-analysis compared outcomes between percutaneous pinning/wiring and open reduction internal fixation (ORIF) with locking plates for treatment of unstable distal radius fractures. Medline, Cochrane, EMBASE, and Google Scholar were searched through December 30, 2015. Twenty randomised controlled trials (RCTs) and non-randomised two-arm studies were included. Outcomes included scores of Disabilities of the Arms, Shoulders and Hands (DASH), visual analogue scale (VAS) pain, and patient rated wrist evaluation (PRWE) score, as well as range of motion (ROM) and complication incidence. ORIF/plating was associated with lower DASH scores but longer procedure time, while there was no difference between the two methods with respect to VAS pain score and PRWE score. The overall incidence of complications, including complex regional pain syndrome, was higher with pinning/wiring, though the incidence of carpal tunnel syndrome and nerve defects was not different. Supination and grip strength were better with ORIF. Radiographically, ulnar variation was greater with pinning/wiring. These results suggest that ORIF/plating is the preferred method of managing unstable distal radius fractures.
