OBJECTIVES: To review a case series of patients with posterior pilon variant fracture using a novel approach, focusing on demographic data, injury pattern, surgical results based on computed tomography (CT) scan, and short-term complications.
DESIGN: Consecutive case series.
SETTING: Level I trauma center.
PATIENTS/PARTICIPANTS: Twenty-five patients with posterior pilon fracture.
INTERVENTION: Posterior pilon fracture open reduction and internal fixation.
MAIN OUTCOME MEASUREMENTS: Parameters measured included age, sex, type of fracture, surgical technique, anatomical reduction, and complications.
RESULTS: Twenty-five patients sustained a posterior pilon fracture, accounting for 13.4% of all operatively treated ankle fractures with median follow-up of 21.7 months. The average age of patients was 42 years (22-62); 19/25 (76%) were female, and 6/25 (24%) were male. A modified posteromedial approach was used in 18/25 (72%) patients. Persistent syndesmotic instability was present in 11/25 (44%) patients after posterior malleolar stabilization. Quality of reduction was assessed under CT scan in 19 patients, with 15/19 (78.9%) having anatomic reduction. We report 2/25 (8%) patients with early wound problems and 7/25 (20%) with short-term complications during follow-up.
CONCLUSION: Posterior pilon variant fracture appears to be less common than previously reported. Most fractures can be satisfactorily treated through a modified posteromedial approach. Albeit obtaining posterior malleolar fracture rigid fixation, syndesmotic instability was more prevalent than expected. The short-term complication rate was low.
LEVEL OF EVIDENCE: Therapeutic level IV.
