Combined Open and Percutaneous Plating for the Treatment of Pilon Fracture.

Background: With the advent of percutaneous plating techniques and anatomical locking plates, open plating combined with percutaneous plating may be a feasible option to reduce pilon fracture soft-tissue complications. The purpose of this study was to evaluate the outcomes of a combined open and percutaneous plating approach for the treatment of pilon fracture.

Methods: Forty-two consecutive patients treated with a combined open and percutaneous plating approach between March of 2010 and February of 2020 for pilon fracture were reviewed retrospectively. The study population consisted of four female patients and 38 male patients with an average age of 47.5 years (range, 15-71 years). The mean follow-up duration was 25.7 months (range, 12-48 months). The combination of a small anterolateral approach and a small anteromedial approach (or a small direct medial approach) was used in all cases. A small posterolateral approach or a small posteromedial approach was added as necessary.

Results: The average ranges of ankle sagittal motion and hindfoot coronal motion at 1 year postoperatively were 43.3° (range, 30°-60°) and 47.7° (range, 40°-55°), respectively. The mean 1-year postoperative visual analogue scale score and American Orthopaedic Foot and Ankle Society score were 0.90 (range, 0-4.0) and 94.5 (range, 78-100), respectively. All patients except one achieved bony union. The mean time to union (except in the one case of nonunion) was 4.5 months (range, 3-8 months). Minor wound breakdown occurred in five cases using combined approaches, but these eventually healed with local wound care. There were no major soft-tissue complications and no instances of deep infection.

Conclusions: A combined open and percutaneous plating approach is a feasible option for the treatment of pilon fracture. This combined plating technique involving a combination of a small anterolateral approach and a small anteromedial approach (or a small direct medial approach) yielded satisfactory outcomes without major soft-tissue complications.
