Failed Reconstruction of the Extensor Pollicis Longus in a Patient with a Major Variation of the Extensor Indicis Proprius Tendon: A Case Report

摘要

Tendon transfer with extensor indicis proprius (EIP) has been performed widely for reconstructing ruptures of the extensor pollicis longus because of its simplicity and clinical outcome. We experienced a rerupture of the extensor pollicis longus restored by incorrect tendon transfer because of a major unrecognized variation in the anatomy of the EIP. Surgeons should perform such transfer with a detailed knowledge of the possible anatomical variations to avoid such serious complications.
