Pain Management during Rehabilitation after Distal Radius Fracture Stabilized with Volar Locking Plate: A Prospective Cohort Study

Introduction. Internal fixation with volar locking plate (VLP) was widely adopted as a first-line choice in treatment of distal radius fracture (DRF). Methods. Total 315 patients with distal radius fracture receiving VLP fixation were included for analysis in this study. The rehabilitation protocol was started immediately after surgery for all patients. During the initial two weeks after surgery, 149 patients received 200 mg celecoxib twice per day, 89 received buprenorphine transdermal patch at 5 μg/h, and 77 received 13 mg codeine plus 200 mg ibuprofen twice per day for pain management. Visual analog scale (VAS) scores of pain at rest, daily activity, and rehabilitative exercise were measured, respectively, every week according to the experiences of the past week in the initial six weeks after surgery. Functional outcomes including range of motion (ROM) for extension, flexion, pronation, supination, ulnar and radial abduction, the disabilities of arm, shoulder, and hand (DASH) score and the validated patient rated wrist evaluation (PRWE), and grip strength were collected at one, three, and six months after surgery. Results. We showed that patients receiving transdermal buprenorphine and codeine/ibuprofen had decreased VAS scores during rehabilitative exercise, better compliance to the rehabilitation program, and thus faster functional recovery. Conclusions. We recommend transdermal buprenorphine or codeine/ibuprofen for pain management during rehabilitation after distal radius fracture stabilized with VLP.
