Transmetatarsal Amputation
- Chopart Amputations:
- General Considerations:
- all viable plantar skin with normal or protective sensation should be preserved;
- intact longitudinal rays in a partial forefoot amputation should be preserved;
- ankle dorsiflexions should be preserved or transplanted, if necessary,
to provide balanced motion at the ankle joint;
- the stump end should be covered with plantar skin to prevent break
down with wt bearing and toe off, or the end of the stump should
by modified by recognized plastic surgical techniques;
- skin grafting should be applied only to the non weight bearing border or dorsum of the foot;
- Ray Amputations:
- w/ ray amputations, the first metatarsal ray may be amputated, w/ only
moderate loss of foot function;
- some argue that medial and lateral longitudinal forefoot amputations in
diabetics are highly (80%) successful;
- others (Wagner) argue that only lateral longitudinal amputations are successful
and that medial forefoot amputations should be abandoned due to a higher
rate of recurrent infection;
- if base of the fifth metatarsal is resected, peroneus brevis insertion
should be reinserted into the cuboid;

- Metatarsal Disarticulations:
- usually need a toe filler to keep the shoe from collapsing;
- since the arches are intact, wt bearing is sufficient but may be
supplemented with an arch support;
- results in bony anterior section which can be difficult to fit
- arch often flattens out over time causingn further wt bearing
problems;
- toe filler may be OK, but often molded arch support is added;
- extended steel shank may add protection during roll over;
- Prosthetic Considerations at Different Amputation Levels;
- Longitudinal Ray Amputations:
- usually lose balance and some wt bearing;
- in many cases no prosthesis is needed;
- molded arch support may help distribute wt bearing more evenly;
- Toe Amputations:
- usually need no prosthetic treatment;
- soft filler may be used but does little;
- loss of great toe eliminates push off, esp. at higher cadences;
