Abstract
Anterior locking plate fixation of the distal radius is a common procedure with reliable results. Failure of fixation is sometimes seen. The aim of the present study was to identify the reasons for failure. In total, 517 cases met the study inclusion criteria. Of them, 23 cases had failure of fixation (4.4%). Failure analysis generated qualitative data. Subsequent thematic analysis identified the primary mode of failure and contributing factors. Primary modes were identified as failure to support all key fracture fragments (n = 20), wrong choice of implant (n = 1), failure of union (n = 1) and poor bone quality (n = 1). Contributing factors were errors in plate positioning, fracture reduction, implant selection and screw configuration, as well as fracture pattern complexity and poor bone quality. Most failed fixations had a primary mode and two or three contributing factors. Overall anterior plating is reliable with a low rate of surgical failure. Knowledge of failure modes will aid operative planning and prevent failure.
