Abstract
Transfer of the extensor indicis proprius was carried out in 28 patients with chronic loss of the extensor pollicis longus. The patients were evaluated after intervals ranging from 4 months to 5 years, and 23 (82 percent) showed excellent recovery of long thumb extensor function, although 9 of these did lose as much as 30 degrees of flexion at the interphalangeal joint. There were two failures (7 percent), and two patients were lost to follow-up. One patient ruptured the juncture of the transfer but responded well to reattachment. There were not complications attributed to removal of this tendon from the index finger.
