Bone closure | Amputation technique

Bone closure

The bone is closed by sutured strips of periosteum (periosteum strips), but the bone is also lengthened and stabilised by periosteum or bone chips. The aim is to protect the tibia and fibula, for example, at the lower leg, from compression by the prosthesis by means of a stable bone connection. During the operation, the patient must usually be treated under general anaesthesia.

A tourniquet is necessary for reasons of clarity and to avoid greater blood loss during major amputations. A tight cuff, which is placed above the amputation area, is used to keep the blood out of the operated area. However, if the cuff is applied too long, tissue loss may occur.

At the end of the operation, one or more drainage tubes are inserted into the operating area to collect the wound fluid from the muscles and bone surface. After a few days, the drainage can be withdrawn again. With the help of a pressure bandage, the wound can be adequately treated. If there is a risk of infection, as may be the case after trauma or vascular disease, antibiotics should be given prophylactically during or before the operation.
