Early Retrieval of Spanning Plates Used for Fixation of Complex Fractures of the Distal Radius.

Background  Spanning plates are being increasingly used for the treatment of complex fractures of the distal radius. The traditional recommendation is to leave the hardware in place for at least 12 weeks. Questions/Purpose  This study assesses the comparative outcomes of spanning plates removed at or before 10 weeks. We hypothesized that acceptable healing and functional outcomes can be achieved with earlier hardware removal to allow for earlier range of motion, rehabilitation, and return to function. Patients and Methods  All patients treated for a comminuted, intra-articular distal radius fracture with a temporary spanning plate were identified. Outcomes of bridge plates removed before 10 weeks were compared with plates removed after 12 weeks. Twenty patients in the short duration cohort were compared with 40 patients in the long duration cohort. Results  All fractures healed and there were 10 complications (4 short duration, 6 long duration) and 2 reoperations (1 short duration, 1 long duration) in the study population. There were no significant differences in final Quick-DASH scores (27.4 short duration, 20.9 long duration) or radiographic alignment. Mean values for wrist extension and ulnar deviation were significantly worse in the long duration cohort, although these differences are of unclear clinical significance. Conclusion  It may be safe to remove spanning bridge plates earlier than what is traditionally recommended. Plate removal at or before 10 weeks did not detract from healing or radiographic alignment. Prospective investigations assessing the optimal duration of fixation for this technique are needed. Level of Evidence  This is a Level IV study.
