Short Term Outcomes Following Open Reduction Internal Fixation Surgery for a Distal Radius Fracture: 2 Week Versus 4 Week Immobilization. A Retrospective Analysis.

Abstract

The study was a retrospective cohort analysis for a 41 month period; from January 2013 to May 2016. It is suggested that patients following a distal radius fracture (DRF) achieve a comparable outcome at 3 and 6 months post surgery regardless of the time they begin mobilization. In previous studies there has been limited analysis of outcomes within the initial 3 months: functional return, time taken from work and use of therapy resources are key outcomes which have not formally been investigated in previous studies. To analyze short term outcomes of patients following open reduction internal fixation (ORIF) for a DRF. A retrospective cohort analysis was conducted to determine primarily if there is a difference in time from work, number of therapy appointments, cost of therapy materials, time to discharge from therapy and secondarily range of motion (ROM) and grip strength (GS); when measured in patients who begin mobilization prior to 2 weeks compared to those who begin mobilization at 4 or greater weeks post surgery. Patients mobilized early were discharged from hand therapy significantly quicker (p = 0.033) and returned to work significantly faster (p = 0.019) than those mobilized later. Patients who began mobilization at 2 weeks or earlier post surgery had significantly greater wrist extension/flexion arc at 4 weeks (p < 0.001) and 6 weeks (p < 0.001) and rotation at 4 weeks (p < 0.001). Patients who begin mobilization at 2 weeks or earlier following ORIF for a DRF will lose less time from work and will be discharged sooner from hand therapy. They will additionally have increased ROM in the early post surgery phase.
