Abstract
Introduction
The delayed presentation of Achilles tendon rupture is common, and is a difficult problem to manage. A number of surgical techniques have been described to treat this problem. We describe the use of Flexor Hallucis Longus (FHL) transfer to augment the surgical reconstruction of the delayed presentation of achilles tendon rupture.
Materials and Methods
Fourteen patients with chronic tendo-Achilles rupture, presenting between April 2008 and December 2010, underwent surgical reconstruction and FHL transfer. Surgery was performed employing standard operative techniques, with shortening of the Achilles tendon and FHL transfer into the calcaneum with a Biotenodesis screw (Arthrex). VISA-A scores were performed preoperatively and six months postoperatively. Complication data was collected by review of the electronic patient record and direct patient questioning.
Results
One patient died of an unrelated cause shortly before outcome scoring, and another patient was excluded because casting in the preoperative period prevented accurate scoring, although he achieved a good post-treatment score. Analysis was therefore carried out on twelve patients. Eleven of the twelve patients had significant improvement in their VISA-A score, with a mean improvement in score of 30 (p < 0.05). There were no significant complications in any of the patients.
Conclusion
Our results show that FHL transfer in the management of chronic Achilles tendon rupture is a good, safe and reliable technique. There is excellent improvement in the mean VISA-A score, with no significant complications. Our results support the use of FHL tendon transfer for patients with chronic tendo-Achilles rupture.
