Ceramic trapezio-metacarpal arthroplasty: Probably half is better than full.

Trapezio-metacarpal arthroplasty is one of the several treatment options available for painful first carpo-metacarpal (CMC) osteoarthritis of hand. In India, we have only Moje ceramic implants available for CMC arthroplasty. Although the literature cites high frequency of loosening and failure with use of Moje ceramic prostheses, all these studies describe results with total carpometacarpal arthroplasty. We expected that hemi-arthroplasty alone, by virtue of trapezium preservation leading to optimal capsular and ligament tensioning will provide good outcome. We wish to present first case of long-term successful outcome of Moje hemi trapezio-metacarpal arthroplasty from India as well as internationally.
