Preservation of lower extremity amputation length using muscle perforator free flaps.
Coverage of any lower extremity amputation stump must be durable to resist external forces, well contoured, and thin enough for proper shoewear or prothesis fitting. Preservation of bone length to maximise the ability to ambulate is also of paramount importance. If local soft tissues are inadequate to fulfil these prerequisites, consideration of a microsurgical tissue transfer is a reasonable option, especially to cover bone or save a major joint. Muscle perforator free flaps, as shown in this series of eight patients using four different donor sites, are a versatile alternative for the necessary soft tissue augmentation. Multiple choices are available and often even from the involved lower extremity to minimise further morbidity. The vascular pedicles of this genré of flaps are relatively exceedingly long and of respectable calibre to facilitate reaching an appropriate recipient site. They can be sensate if desired. Of course, muscle function is by definition preserved. Complications are minimal and usually related to the reason for the amputation in the first place.
