BackgroundFlexor tendon rupture is a rare but major complication associated with volar plate fixation of distal radius fractures.Materials And MethodsWe performed a systematic review to evaluate the demographics, clinical profile, treatment and outcome of flexor tendon rupture following volar plate fixation of distal radius fracture. Electronic searches of the MEDLINE, EMBASE, and Cochrane databases for systematic reviews and conference proceedings were performed. Studies were included if they reported flexor tendon rupture (partial or complete) as a complication of distal radius fracture plating (all levels of evidence).ResultOur search yielded 21 studies. There were 12 case reports and 9 clinical studies. A total of 47 cases were reported. There were 11 males and 23 females (n = 16 studies). The mean age was 61 years old (range 30-85). The median interval between the surgery and flexor tendon rupture was 9 months (interquartile range, 6-26 months). Twenty-nine plates were locking and 15 were nonlocking (n = 20 studies). FPL was the most commonly ruptured tendon (n = 27 cases, 57 %), with FDP to index finger being the second most common (n = 7 cases, 15 %). Palmaris longus tendon graft and primary end-to-end repair were the most common surgical methods used in cases of FPL tendon rupture.ConclusionFlexor tendon rupture is a recognised complication of volar plating of distal radius fracture. Positioning of the plate proximal to the "watershed" line and early removal of the plate in cases with plate prominence or warning symptoms can reduce the risk of this complication.
