Ankle Disarticulation: An Underutilized Approach to Staged Below Knee Amputation-Case Series and Surgical Technique.

The staged approach to below knee amputation has proven to be an effective method of achieving functionality after amputation and reducing risk for postamputation complications. Transtibial or "guillotine" amputations are often used as the first-stage amputation. Disarticulation at the ankle joint is an alternative method that can be used with favorable results and benefits. These include rapid infection decompression while minimizing the blood loss of traditional tibial osteotomy. Here we describe our operative technique, perioperative management, and indications for this surgical procedure.
