Amputation through the tibia and fibula, commonly known as a below knee (BK) amputation, is a surgical procedure that involves the removal of the leg below the knee joint. This procedure is one of the most frequently performed major limb amputations and is typically indicated in cases where the leg is severely damaged due to trauma, infection, or vascular disease. The surgical technique involves careful planning and execution to ensure that the remaining limb is suitable for prosthetic fitting post-operation. The procedure begins with marking incision lines on the skin, followed by the incision of the skin and underlying soft tissues. Surgeons meticulously dissect down to the muscle, identifying and isolating muscle compartments, as well as neurovascular structures, which include various nerves and blood vessels. This careful dissection is crucial to prevent nerve damage and ensure proper healing. The procedure culminates in the resection of the bones, followed by the creation of muscle and skin flaps to cover the amputation site, ultimately preparing the patient for prosthetic rehabilitation.
