Abstract
A non-constrained total joint prosthetic replacement device for metatarso-phalangeal joint. A first component comprises a convex-bearing surface and a rearwardly projecting stem configured to be received in the resected metatarsal bony shaft, and a second component includes a concave-bearing surface and a stem configured to be received within the resected phalangeal bony shaft. A non-bearing intermediate land offsets the convex-bearing surface of the first component from the stem, allowing a full range of anatomical motion notwithstanding the presence of bony overgrowth.
