Syme's Amputation
Pronunciation: SYMZ am-pyoo-TAY-shun
A surgical disarticulation at the ankle joint that retains the heel pad, resulting in a residual limb that may require a specific prosthetic-orthotic interface rather than a standard prosthesis.
Full Definition
Syme's amputation involves disarticulation at the tibiotalar joint with preservation of the heel pad, which provides end-bearing capacity to the residual limb. Because the patient retains partial foot function and a weight-bearing stump, the prosthetic or orthotic management differs significantly from a transtibial (below-knee) amputation. Editors in orthotics documentation must take care to render the possessive eponym correctly as 'Syme's' (with apostrophe-s), following standard eponym conventions. It is commonly confused with a Chopart or Lisfranc amputation, which are more distal partial-foot procedures that typically require orthotic rather than prosthetic management.
Usage
Usage note: Always render with the possessive apostrophe-s: 'Syme's'. Some style guides permit dropping the possessive for eponyms; verify house style before amending.
