Orthotic device and exercise regime for flexor pollicis longus tendon repair in cases with possible Linburg–Comstock anomaly

Abstract

The Linburg–Comstock anomaly is a variation on normal anatomy of the flexor pollicis longus of the thumb and the flexors of the index finger. If not recognised this may contribute to complications after a flexor pollicis longus repair. This article looks at a case where the anomaly may have led to re-rupture of the tendon repair and proposes an orthosis and exercise regime to manage this anatomical variant.
