Forefoot amputation. A trans-metatarsal amputation is the surgical amputation / removal of all the toes along with partial removal of the associated metatarsal long bones. Achilles tendon lengthening may be performed at the same time or sometime after to minimize the forefoot pressures that may result with this type of procedure.
Transmetatarsal Amp. For a transmetatarsal amputation, the front part of the foot is removed anywhere from just behind the ball of the foot to about the midpart of the arch. The bones cut through are the metatarsals and this is how this procedure garners its name. A flap is created to achieve closure of the site. Many times we add the lengthening of the achilles to reduce pressure on end of the amputation stump.
