Early Mobilization Versus Splinting After Surgical Management of Distal Radius Fractures.

backgroundAfter the surgical management of distal radius fractures (DRF) in older patients, further treatment with a splint often follows. It is unclear whether early mobilization might be superior to splinting in this group of patients, as it is in others. In this prospective, randomized, controlled trial, we attempted to determine whether early mobilization yields better outcomes.

methods50 patients over age 70 with DRF were included in the trial. Group A (the splint group) was treated with postoperative immobilization, group B with early mobilization. Clinical follow-up examinations were performed at 2, 6, and 12 weeks and at 6 and 12 months. X-rays were obtained preoperatively, postoperatively, at 6 weeks, and at 6 months. The primary outcome parameter was the modified Mayo Wrist Score (MMWS) at 6 weeks.

resultsAt 6 weeks, the functional outcome was better to a statistically significant extent in group B (MMWS; 65/100 vs. 55/100 [q25 : 55/40 - q75 : 70/70; p = 0.025]). No difference between the two groups was demonstrable in their further clinical course. The estimated regression model revealed a statistically significant effect of the method of treatment (p = 0.023). There were no differences in hand strength or in x-ray findings. DISCUSION: Early mobilization is associated with better wrist function on initial follow-up, without any demonstrable disadvantage with respect to secondary dislocation. The psychological benefit and protective function of wrist splinting in patients who are in danger of falling should nonetheless be investigated in further studies.
