Timing of Open Reduction and Internal Fixation of Ankle Fractures

Background. Unstable ankle fractures are treated with open reduction internal fixation (ORIF) to prevent posttraumatic arthritis. Typically, ORIF is performed as an ambulatory surgery several days to a few weeks after injury. It is unclear what effect this delay may have on functional outcome. This study aimed to assess the effect of timing of ankle ORIF on wound complications and functional outcome. Methods. A retrospective review of 121 patients who underwent ankle ORIF was performed. A total of 58 patients had a follow-up of at least 24 months. Time between injury and surgery greater than 14 days was defined as "delayed." Demographic variables, injury characteristics, length of surgery, and postoperative stay were documented. Comparison of demographic variables, wound complications, and functional outcome determined by Foot and Ankle Outcome Score (FAOS) was performed. Results. 118 patients were included. The duration between injury and surgery was 6 days in the "early" group and 19 days in the "delayed" group. There were no significant differences in demographic variables, injury characteristics, and length of surgery between the groups. Wound complications in the early and delayed groups were 5% and 11.8%, although this difference was not statistically significant. Among 58 patients who had a follow-up of at least 24 months, the median follow-up time was 38 (range, 24-76) months. Each subscale of FAOS demonstrated no significant difference. Conclusion. Ankle ORIF more than 14 days after injury did not significantly increase the rate of wound complication, nor did it impair ultimate functional outcome in this group.
