Transtarsal Amputation
Pronunciation: trans-TAR-sal
A partial-foot amputation performed through the tarsal bones, preserving the heel pad and some midfoot structures.
Full Definition
A transtarsal amputation removes the forefoot and a portion of the midfoot at the level of the tarsal bones, leaving a functional heel pad and plantar skin for weight-bearing. It is less common than Lisfranc or Chopart amputations but may be preferred when tissue preservation allows. Prosthetic management typically involves a custom foot orthosis or partial-foot prosthesis to restore push-off and gait mechanics. Editors must distinguish transtarsal amputation from Lisfranc (tarsometatarsal) and Chopart (midtarsal) amputations, which have specific eponymous names in clinical documentation. Consistent use of the anatomical level descriptor is important in surgical and rehabilitation records.
Usage
Usage note: Do not use interchangeably with 'Chopart amputation' or 'Lisfranc amputation'; each denotes a distinct anatomical level. Verify level with the surgical record when editing.
