Surgical distractors designed to provide a force that produces noninvasive separation of the ankle joint (i.e., distraction) while allowing access to the joint space. These distractors typically consist of an adjustable force mechanism that may include clamps, screws, levers, and a strap attached to the foot; the mechanism may be attached to the operating table (e.g., on a leg holder) or other type of support. Gross adjustment rotating the bar, constant distraction, and fine adjustment are possible using this mechanism; some distractors include a device (dynamometer) to measure the retraction force applied to the joint. Ankle distractors are intended for use during ankle and/or foot surgical procedures, including ankle and foot arthroscopy, ligament repair, and ankle arthrodesis.
