Syme Amputation
Pronunciation: SYME (rhymes with 'time')
A disarticulation at the ankle joint with retention of the heel fat pad, providing a weight-bearing residual limb.
Full Definition
A Syme amputation is a surgical procedure involving disarticulation at the tibiotalar (ankle) joint with careful preservation of the heel fat pad, which serves as a durable weight-bearing surface. Named after Scottish surgeon James Syme, it results in a longer residual limb than a standard transtibial amputation and allows for limited end-bearing ambulation without a prosthesis. The prosthetic challenges include the bulbous distal end and restricted space for prosthetic componentry. In clinical documents, 'Syme' should always be capitalised as an eponym; editors should not lowercase it.
Usage
Usage note: Always capitalise 'Syme' as an eponym. Do not use 'syme' in lowercase, even in informal clinical notes.
