Effect of Lymphedema Treatment for Management of Acute Pilon Fractures.

Abstract

Pilon fractures are high-energy injuries that often result in considerable edema and compromise of the soft tissue envelope of the ankle. These injuries are typically staged with an external fixator until the soft tissue is amenable for definitive fixation. This study was conducted to determine the effects of lymphedema treatment for the management of pilon fractures. Patients who underwent open reduction and internal fixation of pilon fractures between 2007 and 2014 at the authors' level II trauma center were identified by Current Procedural Terminology codes indicative of placement of an external fixator (20690) and open reduction and internal fixation of a pilon fracture (27826, 27827, or 27828). The primary efficacy endpoint to determine negative outcomes was 90 days after definitive fixation. Eighty-two patients with 84 pilon fractures met inclusion criteria. Forty-eight ankles (57%) received lymphedema treatment. There were no significant differences in population demographics between the control and treatment groups. Median times to internal fixation in the control and treatment groups were 20 days (inter-quartile range, 15.5-30 days) and 11 days (interquartile range, 6-18 days), respectively. This difference was statistically significant (P=.001). Additionally, there was no significant difference in the overall incidence of wound complications between the control and treatment groups (P=.246). Compression wrapping for posttraumatic edema was effective in reducing the time needed for soft tissues to be appropriate for definitive surgical fixation of pilon fractures without increasing the risk of wound complications. These promising results warrant future study. [Orthopedics. 2017; 40(4):e668-e674.].
