Endoscopic Flexor Halluces Longus transfer for Chronic Achilles Tendon rupture - technique description and early post-operative results.

BACKGROUND

Achilles tendon ruptures may lead to proximal retraction of the stump if not treated acutely, increasing the chances of poorer functional outcomes. The flexor halluces longus transfer is a well-established treatment option, usually performed as an open procedure. The aim of this paper is to report the preliminary results and describe the technique of endoscopic flexor halluces longus transfer.

MATERIAL AND METHODS

Six patients with chronic Achilles tendon injuries or re-ruptures were treated with endoscopic FHL transfer. The Achilles Tendon Rupture Score was used to clinically evaluate the patients. Single leg heel rise ability, functional hallux weakness, complications and procedure length were also checked.

RESULTS

On average, we took 56 minutes to perform the surgery. All patients had a major increase in the ATRS score value postoperatively. Single leg heel rise was possible for all patients without limitation. None of the patients noticed functional weakness of the hallux during daily life activity and no wound or soft tissue complications were seen.

CONCLUSION

Endoscopic FLH transfer is a reliable option for patients with high skin risk and soft tissue complications. Other studies are needed to compare this technique with the open procedure, gold standard by now, to ensure its safety and efficacy.
