Syme Prosthesis.
This is one of the lower limb prosthesis which can be fitted to an amputee,where by the amputation is between tibia/fibula and talus this accompany with reshaping of tibia and fibula to remove sharp edges of medial and lateral malleoli.

Syme prosthesis can be fabricated in two ways.
(i) Prosthesis with hard outer socket and inner soft (soft liner) like in trans tibial prosthesis,as the distal end of the stump is wider than the mid-third area,the inner socket is cut to enable the stump distal end to go through in the socket..

(ii) Prosthesis with hard socket but with a soft cap at the distal end .Normally the socket used to have an opening cap posteriorly to easy donning of the prosthesis.

Advantages of the Syme Prosthesis.
The user can bear weight 100% at the distal end of the stump without or with minimal pain especially when calcaneous bone is fused to tibial (pirogoff).

Disadvantage of Syme Prosthesis.
Brings complications when fabricating of the prosthesis since the stump is too long,the assembling of the prosthetics foot and ankle block to the socket becomes difficult as the sound limb becomes shorter than the amputated side.
