Introduction of limb reservation operation for an infected and all muscles and intermuscular vessels necrosed leg / 解放军医学杂志

ABSTRACT

Objective to study the factors of delaying survival of the ankle and foot which were linked with leg only by skin, fascia and tibia after all the infected and inactivated muscles and intermuscular vessels had been removed, and to study the effect of artery blood supply reconstruction to avoid the necrosis and ischemia contracture of the foot. Methods The leg was linked with ankle and foot by the tibia which was covered only by skin and fascia after all the muscles, interosseous membrance, intermuscular vessels and fibula had been removed. And then the artery blood supply for the injured limb was reconstructed by stages. Results The sense of haphalgesia, with normal temperature and color, recovered in the injured limb 7 months after operation, no contracture and deformity happened in the food muscles and joint, and the patient may smooth stand and walk with a stick freely. Conclusion The necrosis and ischemia contracture of foot was delayed by reticular collateral circulation among skin, deep and superficial fascia and tibia of the injured limb, although the blood supply was very little after all the muscles and intermuscular vessels had been removed because of infection and necrosis. Finally the injured limb was reserved successfully by artery blood supply reconstruction. The clinical effect was satisfactory.
