Samenvatting

Marginal fracture types of the distal radius may require volar plate positioning distal to the watershed line. Subsequently, plate prominence with direct friction with the flexor tendons occurs which is associated with flexor tendon pathology. Standard plate removal can be proposed. This cohort study examined clinical outcome, patient satisfaction and ultrasonographical assessment of the relation of the flexor pollicis longus (FPL) and the volar rim after standard plate removal. Twenty patients with volar plate prominence after osteosynthesis for distal radius fractures were included. Plate removal was performed at least 4 months after initial surgery. The mean age was 60 years (range 39–84). The average delay from hardware removal to assessment was 2.9 years (range 1.0–5.0 years). Mean flexion, extension and radial deviation were significantly decreased (p ' 0.05) compared to the contralateral side, while ulnar deviation, pro- and supination and grip strength were not. Mean QuickDASH score was 21.5. 85% of patients described their result as good to excellent. 80% would undergo the intervention again. During ultrasonography, distance from FPL to volar rim remained significantly decreased compared to the uninjured side in neutral and flexed position (p ' 0.05) despite plate removal. The largest distance between the FPL and the volar cortical bone, which is mainly occupied by the pronator quadratus, did not differ. In this study, the range of motion and FPL distance to the distal radius normalized only partially compared to the uninjured wrist after standard plate removal.
