COMPRESSION ARTHRODESIS OF THE SMALL JOINTS OF THE HAND

A number of techniques for achieving small joint arthrodesis in the ha nd combine various forms of internal fixation with external cast or sp lint immobilization. Rates of arthrodesis in most cases are quite high . However, the prolonged period of adjacent joint immobilization from casting tan extend rehabilitation time and limit hand function during healing. Compression arthrodesis has been used effectively in a number of larger joints, such as the knee and ankle, Miniaturization of exis ting external fixation compression devices now enables the application of this principle to the small joints of the hand. A series of 20 met acarpophalangeal and interphalangeal joints underwent arthrodesis in w hich a miniature external fixation/compression frame was used. Ninetee n of 20 joints demonstrated complete primary arthrodesis within 6 week s; one fibrous union developed in a distal interphalangeal joint and n o postoperative deformities occurred. Complete stabilization was provi ded by the fixator, thus allowing immediate postoperative adjacent joi nt function.
