Comparison of Outcomes and Complications of 1- and 4- week Cast Immobilization after Distal Radius Surgery

Background & Aims: Metaphysical distal radius fractures are common fractures account for almost half of the fractures in Orthopaedic Emergencies. According to different studies, 1-6 weeks cast immobilization after distal radius surgery has been recommended. The aim of this study was to compare outcomes and complications of short-term and long-term immobilization treatment methods. Methods: In a randomized clinical trial, 50 patients with metaphysical distal radius fractures and extra joint or intra joint fractures without comminution referred to the Emergency Unit of Shohada Hospital in Tabriz, Iran who were treated by percutaneous pinning were selected and divided into two groups of immobility for one week (group 1) and immobility for four weeks (group 2). Results: Loosing of pins was not seen in any of the groups. There were no significant differences in intensity of pain, infection at the site of pins and range of motion improvement between the two groups. Most of the patients in group two like group one have gained their ability in three months, but 1.5 month after the treatment return of motions in the early motion group was significantly faster. Conclusion: According to these findings, there is no difference in final therapeutic and functional outcomes between 1- and 4- week post operative immobility. Earlier initiation of movements after one week is not associated with more complications in comparison to late initiation of movements, but patients return to their daily activities earlier.
