Extensor Indicis Proprius Transfer to Supplement Replacement Arthroplasty of the Rheumatoid Hand

Abstract

A new procedure is described to cope with the rotation deformity so often seen after replacement arthroplasty of the destroyed metacarpophalangeal joints in rheumatoid arthritis. The same procedure, in combination with a similar transfer to the ring and little fingers, but using extensor digiti minimi as the motor, can be used as a suspension procedure to stabilise the early unstable metacarpophalangeal joint.

Thirty hands have been treated with the longest follow-up of two-and-a-half years; so far the results have been encouraging.
