Transtibial Amputation With Fibulectomy and Fibular Collateral Ligament-Biceps Reconstruction: Surgical Technique and Clinical Experience.

Objectives: To describe our clinical experience and surgical technique of transtibial amputation with fibulectomy and fibular collateral ligament-biceps reconstruction for management of, particularly short, transtibial amputations with proximal fibula prominence, overt instability, or inadequate soft-tissue coverage.
Design: Retrospective review.
Setting: Level II trauma center.
Patients: Twelve consecutive patients who underwent transtibial amputation with fibulectomy and fibular collateral ligament-biceps reconstruction between 2008 and 2021.
Intervention: We reviewed patient medical records, radiographs, and clinical photographs.
Main Outcome Measurements: Complications, instability, and pain.
Results: Eight patients underwent acute transtibial amputation with fibulectomy and reconstruction, whereas 4 patients underwent amputation revision with fibulectomy and reconstruction for chronic pain. All 12 patients were men, with a median age of 39 years (interquartile range, 33-46). All injuries were due to high-energy mechanisms, including improvised explosive device (n = 8), rocket-propelled grenade (n = 2), gunshot wound (n = 1), and motor vehicle accident (n = 1). After a median follow-up of 8.5 years (interquartile range, 3.4-9.3), there was one complication, a postoperative suture abscess. No patients had subjective lateral knee instability after the procedure, and the average pain scores decreased from 4.75 to 1.54 ( P = 0.01). All patients returned to regular prosthesis wear and maintained independent functioning with activities of daily living.
Conclusions: Our experience with fibulectomy and fibular collateral ligament-biceps reconstruction demonstrated no subjective or clinical postoperative instability and may be a useful adjunct for managing transtibial amputations with fibular instability or prominence, pain, or skin breakdown at the fibular head.
