Low-Profile Partial Foot Prosthesis

MARY WILLIAMS CLARK, MD*, ANDRICHARD ROSENBERGER, CPO (DECEASED)Charlottesville, Virginia


Most devices available for fitting patients with partial foot amputations incorporate an ankle-foot orthosis to improve weight transfer at toe-off, but this inhibits ankle motion. Some patients and families view AFOs as being bulky and therefore uncosmetic. Our objective was to develop an aesthetically pleasing prosthesis allowing good gait in an active child. The design includes a flexible Silastic liner covered by a foot prosthesis with a rigid proximal brim, anterior opening, and flexible toe. The trimlines do not extend above the malleoli.

A 5-year-old girl with a Lisfranc level, and a 16-year-old boy with a Chopart level (with a transferred anterior tibialis into the talar neck) have worn the prosthesis for 3 and 2 years respectively, and are both pleased with the fit, appearance, and function. We are satisfied with their gaits.
