Repair of Chronic Achilles Tendon Rupture by Modified Bosworth Technique

Introduction: The Tendo-achilles, also known as the calcaneal tendon is a strong fibrous tissue structure that connects muscles of the calf to the heel (calcaneus). The calf muscles-gastrocnemius and the soleus muscle along with the plantaris muscle, unites into a strip of tissue and becomes the Tendo-achilles at the lower end of the calf and acts as a main flexor of the ankle joint. The Achilles tendon rupture is considered to be chronic if the injury is past 4-6weeks of duration. Materials and Method: From May 2016 to May 2018, 15 Patients with long-standing rupture of the Achilles tendon were treated with the operative technique mentioned below, in MMDU, Mullana, Ambala. All the patients gave informed consent prior to being included in the study. Results All patients were evaluated according to The American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score. 8 patients had excellent results, 4 patients had good results, 2 had fair results and 1 patient had poor result. All patients resumed work at 6 months postoperatively. Conclusion: Our technique is ideally suitable for chronic ruptures in zone I (where there is no distal stump available for repair) and ruptures that have a large gap of more than 5-6 cms. This is accomplished with a single long incision, with a good post-operative range of ankle motion and function and no major post op complications.
