POST-TRAUMATIC COMBINED FLEXION OF THE THUMB, INDEX AND MIDDLE FINGER AFTER INTRINSIC MUSCLES RECONSTRUCTION OF THE HAND: A CASE REPORT

Abstract

We report a case in which simultaneous flexion of the thumb, index and middle finger occurred 6 months after the surgical reconstruction of the adductor (AM) and first dorsal interosseous (IO) muscles. An anomalous connection in the form of tendon slip associated to fibrous adhesions between the flexor pollicis longus (FPL) tendon, flexor digitorum profundus indicis (FDPI) and middle finger (FDPM) tendons were found. Either ultrasound (US) examination or magnetic resonance imaging (MRI) were unable to detect the site of adhesion. Excision of the slip and radical tenosynoviectomy led to early functional recovery.
