Split distal flexor pollicis longus tenodesis: long-term results

Abstract

A thumb lacking intrinsic muscle function but having extrinsic flexion will hyperflex in the interphalangeal joint giving a positive Froment's sign. This can effectively be prevented with split flexor pollicis longus tenodesis. The mean postoperative range of motion in the IP joint of 39 hands was 28 (18)° and 23 (20)° six and 12 months postoperatively. The procedure makes arthrodesis (temporary or permanent) superfluous. This procedure can be recommended strongly.
