Insight of the Knot of Henry: A Case Report

Tendon transfer of flexor digitorum longus tendon(FDLT) or flexor hallucis longus tendon(FHLT) into the tibialis posterior tendon is carried out in patients with tibialis posterior dysfunction. FDLT and FHLT are connected in the region of the Knot of Henry. The present study has investigated the anatomical variations of this tendinous interconnection. The results could be used to determine which of two tendons should be transected proximal to the region of knot of henry in surgical treatment of tibialis posterior dysfunction. The transaction of FDLT /FHLT proximal to region of Knot of Henry for repair of tibialis posterior dysfunction would result in retention of function of the hallux and lesser digits in majority of cases.
