Minimally invasive Achilles tendon repair has recently gained popularity amongst foot and ankle surgeons. This study aims to quantify the risk of sural nerve injury when using the Achillon device (Integra), as well as delineate its anatomical relationship to the Achilles tendon. In 15 cadaveric specimens, the Achilles tendon was transected through a 2cm transverse incision made 4cm proximal to the palpable Achilles tendon insertion point. The Achillon device was inserted beneath the paratenon both proximally and distally and six needle passers mounted with sutures were introduced percutaneously into the tendon (x3 proximal and x3 distal). We dissected around the Achillon jig to determine whether the needle and suture had punctured the sural nerve. We also documented the position of the sural nerve in relation to the Achilles tendon.Introduction
