Contemporary demographics and complications of patients treated for open ankle fractures

Open ankle fractures are rare injuries with a high likelihood of wound complications and subsequent infections. There is limited information about the complications and outcomes of these injuries in different age groups. The aim of this study was to assess the contemporary demographics and complications related to this injury. We performed a chart review of all the 3030 patients treated for ankle fractures at a Level 1 trauma centre from 2006 to 2011.137 (4.5%) patients had an open ankle fracture. The demographic data, injury mechanism, comorbidities, and fracture type were collected. Treatment, complications, length of stay and number of outpatient visits were also recorded. The mean age of the patients was 60 years and 56% were women. Most fractures were Weber type B with a medial sided wound (93%). Only 20% of the fractures were the result of high-energy trauma, and 31% were Gustilo grade III injuries. Immediate internal fixation was performed in 82% of patients, and the wound was primarily closed in most cases (80%). The incidence of postoperative wound necrosis and deep infection was 18% and 17%, respectively. There were more deep infections if pulsatile lavage was used during the wound debridement (p = 0.029). About 14 (10%) patients required a flap reconstruction to cover the soft-tissue defect. Every other patient (54%) had a complication, and 21 patients (15%) suffered a long-term disability related to the injury. The number complications did not differ for nighttime and daytime operations (p = 0.083). High-energy injuries were more common in younger patients (p < 0.001) and these patients also had more lateral sided open wounds than older patients (p = 0.002). Interestingly, younger patients also had significantly more complications (p = 0.024), suffered more often from chronic pain (p = 0.003), and required more flap reconstructions (p = 0.026), reoperations (p = 0.026), and outpatient clinic visits (p = 0.006). Open ankle fractures have a high complication rate and often require multiple surgical procedures. In young patients these injuries are more likely to be the consequence of high-energy trauma leading to more complications and subsequently increased healthcare resource utilisation.
