Abstract
OBJECTIVES: To assess the healing and radiographic outcomes of displaced and comminuted talar neck fractures treated with medial position screws augmented with lateral minifragment plate fixation. DESIGN: Retrospective case series. SETTING: Two level I trauma centers. PATIENTS: The records of 26 patients with displaced and comminuted talar neck fractures who underwent open reduction and internal fixation with medial-sided position screws augmented with lateral minifragment plates. INTERVENTION: Surgery consisted of medial and lateral approaches to the talus, fixation with a laterally placed minifragment plate, and screw construct augmenting sagittal-plane-oriented, medial-sided position screws. MAIN OUTCOME MEASUREMENTS: The incidences of nonunion, malunion, avascular necrosis, post-traumatic arthritis, and symptomatic implants. RESULTS: Nonunion occurred in 3/26 (11.5%) displaced and comminuted talar neck fractures. There were no instances of malunion. Avascular necrosis developed in 7/26 (27%) cases. Post-traumatic arthritis was the most common complication affecting 10/26 (38%) tali. The subtalar joint was most commonly affected. There were no instances of hardware removal due to symptomatic medial impingement. CONCLUSIONS: Lateral minifragment plate fixation augmenting medially placed sagittal plane position screws provides a length stable construct that prevents talar neck shortening and malunion. Medial position screws can help avoid secondary surgeries for removal of symptomatic implants due to medial impingement as is common with medially based minifragment plates. This fixation strategy should be considered in the setting of displaced and comminuted talar neck fractures. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
