ObjectivesThe purpose of this study was to compare the pain scores and the rates and doses of opioid use in patients undergoing volar locked plate fixation of intra-articular distal radius fractures using or not postoperative immobilization.MethodsThis was a prospective randomized controlled trial. Thirty-nine patients with distal radius fractures scheduled to receive volar plate fixation were randomly assigned to receive a short forearm splint for two weeks postoperatively or conventional bandage with early wrist mobilization. Thirty-six patients completed the follow-up. The outcome measurements included pain scores (0-10 points); rates and doses of tramadol use; DASH score; wrist range of motion; patient satisfaction; and complication rates. The last follow-up assessment was performed at 6 months.ResultsThe pain scores were similar between the groups during hospital stay, as well as after hospital discharge within the first week and in subsequent assessments up to six months. The rates of tramadol use were greater in the No splint group during hospital stay, but this difference was not statistically significant (No splint = 65%; Splint = 47%; p = 0.296). Likewise, the doses of tramadol intake were higher in the No splint group during hospital stay (No splint = 218 mg; Splint = 167 mg; p = 0.273) and after discharge (2nd day: No splint = 112 mg; Splint = 75 mg; p = 0.286), with no statistically significant differences. The functional results and complication rates were similar between the groups.ConclusionsIn this study, there was a trend to a greater use of tramadol in patients who did not use immobilization and started early wrist mobilization after volar locked plating of distal radius fracture, compared with patients who were immobilized for two weeks. The pain scores were similar but may have been influenced by the unbalanced use of opioids between the groups. The functional results and complication rates were not influenced by the use of immobilization.Level Of EvidenceTherapeutic Level I.Copyright © 2018 Elsevier Ltd. All rights reserved.
