Transtarsal Amputation
Pronunciation: trans-TAR-sal
An amputation performed through the tarsal bones of the foot, preserving the heel pad and a portion of the foot.
Full Definition
A transtarsal amputation is a partial-foot amputation level in which the surgical transection occurs through the tarsal region, distal to the ankle joint. Common examples include the Chopart and Lisfranc amputations, each named for the anatomical joint level involved. Because the heel pad and portions of the foot are retained, gait and balance considerations differ substantially from more proximal levels. Editorial caution is warranted when distinguishing transtarsal from transmetatarsal amputation; both are partial-foot levels but involve different anatomical landmarks and prosthetic management strategies.
