Background: The timing of surgery for closed ankle fracture is controversial. Conventional teaching recommends either immediate surgery or a delay of 5–7 days in order to minimise soft tissue complications. However, there have been no large studies to produce clear guidelines and the literature is conflicting. Some authors suggest that delayed surgery results in increased risk of wound complications, less satisfactory rate of anatomical reduction, increased hospital stay and health service cost.

Objective: We aimed to determine whether surgery can be safely performed in an intermediate time frame with respect to soft tissues complications.

Method: We performed retrospective analysis of case notes and plain radiographs of 85 patients undergoing open reduction and internal fixation for closed ankle fractures at our unit in 2004. Data was analysed using the StatView statistical analysis program. Continuous variables were assessed for association with wound complication by means of an unpaired t-test. Nominal variables were assessed using Fisher’s exact test.

Results: The overall rate of infection in our population of 85 patients was 9.4%. This comprised 7 superficial wound infections and one deep infection. Patients were classified into early (within 1 day), intermediate (between 2–6 days) and delayed (after 6 days) groups according to the time delay prior to surgery. Only 1 patient in the intermediate surgery group developed infection compared to 6 in the delayed group and this was statistically significant (p = 0.046).

Conclusion: We suggest that with experience, meticulous soft tissue handling and good operative technique, delaying surgery until swelling has subsided is unnecessary in the majority of patients and is associated with a higher risk of wound complication.
