Prosthetic Hemi-Arthroplasty for Post-Traumatic Articular Cartilage Loss in the Proximal Interphalangeal Joint

Abstract

This article discusses the indications, contra-indications, and technique for proximal interphalangeal joint prosthetic hemi-arthroplasty in the setting of sub-acute or chronic post-traumatic articular cartilage loss. Two case examples are provided: one for replacement of the head of the proximal phalanx, the other for replacement of the base of the middle phalanx.This procedure serves as a recently available alternative to fusion, silicone total joint replacement, total joint arthroplasty with unlinked surface replacements, volar plate arthroplasty, hemi-condylar osteochondral autograft reconstruction, or free vascularized joint transfer.

In vitro comparison of wear characteristics of PyroCarbon and metal on bone: Shoulder hemiarthroplasty

“…Favorable outcomes have been reported for use of PyC for interposition and hemiarthroplasty in the hand and wrist. [8][9][10][11][12][13] Similarly, promising results have been demonstrated using PyC as the articulating surface for radial head replacements. [14][15][16][17] Short-term follow-up of PyC shoulder hemiarthroplasty has been reported.…”
