Treatment of Distal Radius Fracture: Does Early Activity Postinjury Lead to a Lower Incidence of Complex Regional Pain Syndrome?

Background: The optimal treatment for a distal radius fracture (DRF) remains an ongoing discussion. This study observed whether early activity postinjury can lead to the prevention of type 1 complex regional pain syndrome (CRPS-1). Method: Patients who underwent nonoperative treatment for a DRF were invited to participate in this study. Patients followed an exercise program with progressive loading exercises at home immediately after cast removal. After a minimum of 3 months, patients were interviewed by telephone to determine the presence of disproportionate pain. If present, the patients were seen during a clinical consultation to determine whether they had CRPS-1, using the Budapest Diagnostic Criteria. Results: Of the 129 patients included in this study, 12 reported disproportionate pain, and none were diagnosed with CRPS-1. The incidence of CRPS-1 was zero in this study. Conclusion: A more active treatment approach seems to lower the incidence of CRPS-1. A larger randomized study is necessary to strengthen the evidence.
