Tibialis anterior tendon transfer using bone anchor for dynamic supination in congenital talipes equinovarus.

Abstract

Tibialis anterior tendon transfer (TATT) is a recognised procedure for the treatment of recurrent congenital talipes equinovarus. The most common technique in use requires three skin incisions and breaching of the plantar tissues, risking pressure areas and damage to neurovascular structures. There have been no studies showing the clinical results of the use of a bone anchor to secure the tendon without drilling through the lateral cuneiform. This study presents the largest series of outcomes for such a procedure. Retrospective case series. Electronic records for all children under 18 undergoing TATT with anchor fixation included. Outcomes recorded were a failure of the tendon transfer and complications. Seventy-seven feet were identified in 61 children with a male-to-female ratio of 2.5:1, the average age at surgery of 5.6 years, and an average follow-up of 4.4 years. There were no cases of pullout of the anchor. Seventy-six cases (98.7%) had no recurrence of dynamic supination on follow-up. No revision surgery was required. Consistently reliable, reproducible and safe fixation of the tibialis anterior tendon in TATT can be achieved using a bone anchor for the treatment of dynamic supination in children with clubfeet following correction using the Ponseti method and is a quick and straightforward alternative method to traditional techniques.
