Background: The purpose of this study was to determine the impact of surgeon volume on outcomes following ankle fracture fixation. Methods: Over 7 years, 362 patients who met inclusion criteria (>18 years with rotational ankle fractures) were identified and treated by orthopaedic surgeons at several hospitals within an academic medical center and were retrospectively reviewed. Surgeons that completed less than 24 ankle fixations per year (<90th percentile) during the study period were classified as low-volume (LV) and surgeons completing 24 or more ankle fixations per year (>90th percentile) were classified as high-volume (HV). Chart review was conducted to gather data regarding perioperative, radiographic, inpatient, and long-term outcome data (average 12-month follow-up). Results: One hundred thirty-four patients (37.0%) were treated by LV surgeons and 228 (63.0%) were treated by HV surgeons. Although both cohorts had a similar breakdown of fracture patterns ( P = .638), the LV cohort had a greater incidence of open fractures ( P = .024). No differences were found regarding wait time to surgery, surgery duration, and LOS. Radiographically, more patients in the HV cohort achieved anatomic mortise after surgery (96.5% vs 89.6%, P = .008). Patients in the LV cohort took longer to heal radiographically (4.27 ± 2.4 months vs 5.59 ± 2.9 months, P < .001), and also had higher rates of reoperation and hardware removal ( P < .05). Lastly, all cost variables were lower for high-volume surgeons ( P < .05). Conclusion: In this single-center study, we found that patients treated by LV surgeons took 30% longer to heal radiographically and had greater reoperation rates than those treated by HV surgeons. Additionally, patients treated by high-volume surgeons had more anatomic postoperative radiographic ankle mortise reductions and was less cost-effective than when performed by high-volume surgeons. Level of Evidence: Level III, retrospective comparative study.

Introduction: The purpose of this study was to evaluate patient outcomes following a standardized algorithmic approach to ankle mortise stabilization, following rotational fracture, utilizing direct repair of the posterior malleolus in the prone position. Methods: Eighty consecutive patients with unstable rotational ankle fractures that involved the posterior malleolus were analyzed. All underwent direct repair of the posterior malleolus regardless of size through a posterolateral approach. Electronic records were retrospectively reviewed for demographic information, initial injury and operation details, healing status, and complications. Preoperative and postoperative radiographs were obtained to assess the initial injury and healing was determined both by radiographic and clinical progress at follow-up visits. Results: Average posterior malleolus fragment width was 8.1 ± 3.7 mm (range = 2.1-19.9 mm) and percentage of the articular surface was 23.6% (range = 7.1%-56.7%) on the lateral radiograph. Overall, 80/80 (100%) patients healed their ankle fractures by a mean 2.9 ± 1.1 months. Only 1 (1.3%) patient required transsyndesmotic fixation following posterior malleolus repair. Mean range of ankle motion was as follows: dorsiflexion 20° ± 10°, plantarflexion 34° ± 10°, inversion 8° ± 4°, and eversion 7° ± 4°. Seventy-nine patients (98.8%) had an anatomic mortise reduction. Nine patients (11.3%) had a superficial wound complication, 3 patients (3.8%) had dysesthesia in the sural nerve distribution, and 1 patient (1.3%) lost reduction of the medial malleolus. Conclusion: Patients who undergo direct repair of the posterior malleolus in the prone position can expect a high rate of healing with superficial wound breakdown being the biggest problem, which was associated with an ankle fracture dislocation. Posterior malleolus fixation may obviate the need of transsyndesmotic stabilization. Levels of Evidence: Retrospective Level IV
