Effective treatment of posttraumatic and postoperative edema in patients with ankle and hindfoot fractures: A randomized controlled trial comparing multilayer compression therapy and intermittent impulse compression with the standard treatment with ice

摘要

Background: After ankle and hindfoot fractures, edema has a major impact on the time for surgical intervention and may increase the risk of wound complications and infection postoperatively. The aim of this study was to evaluate the efficacy of multilayer compression and intermittent impulse compression therapy in reducing ankle and hindfoot edema compared with the standard treatment with elevation and ice. Methods: This was a randomized, controlled, single-blinded clinical trial using a repeated-measures design. Fifty-eight patients with unilateral fractures of the ankle or hindfoot were randomized into the cold pack (control) group, the bandage group, or the impulse compression group and were analyzed according to the intention-to-treat principle. The primary outcome was the reduction of edema as measured with the figure-of-eight-20 method. Results: Preoperatively and postoperatively, there were significant differences in edema reduction between the bandage group and the control group. After two days of intervention, the median preoperative edema reduction in the control group was -2.0 mm (-5%) compared with -11.0 mm (-23%) in the bandage group (p < 0.017), and -0.3 mm (0%) in the impulse compression group (p > 0.017). Postoperatively, after two days, the median edema changes were +3.5 mm (+7%) in the control group compared with -7.3 mm (-22%) in the bandage group (p < 0.017) and +5.0 mm (+46%) in the impulse compression group (p > 0.017). Conclusions: Multilayer compression therapy results in a faster reduction of ankle and hindfoot edema, although with less ankle dorsiflexion on postoperative day three than the control group, and can be recommended as an alternative treatment. Intermittent impulse compression applied without any extra compression by stockinette or bandage and without elevation in off-session periods cannot be recommended as a superior alternative to the treatment with ice.
