Requirements for a metacarpophalangeal joint prosthesis for rheumatoid patients and suggestions for design

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Requirements for a metacarpophalangeal joint prosthesis for rheumatoid patients are defined and suggestions for a new design are described. The reason for designing such a prosthesis is to propose a better solution for the most required indication of a metacarpophalangeal joint artificial replacement. The most important clinical requirement is the ability to perform a task even in the absence of any significant capsulo-ligamentous structure, because it is likely that most patients will require the arthroplasty in a late stage of the disease. A self-stable prosthetic articulation and circular cross-sectional stems are suggested; the latter may bring an advantage in improved transfer of stresses at the stem-bone interface. To cope with the requirement of a self-stable design, allowing limited but long-lasting load bearing, a limitation in the range of motion of the implant is suggested.
