Titanium anchors for the repair of distal Achilles tendon ruptures: preliminary report of a new surgical technique.

From January 1995 to July 1996, the authors used Mitek GIV titanium anchors to treat seven patients with acute rupture of the Achilles tendon (four men, three women; average age 52.42 years; range, 33-62 years). All subjects had a total rupture of the most distal aspect of the tendon; none had an avulsion fracture. After dissection down to the paratenon, the reinsertion site was selected and a 2 to 3-cm-long trough carved through the cortex. Three holes were drilled at a distance of 0.5 cm one from the other and 1 cm parallel and distal to the trough. The anchors were then threaded, inserted into the holes, and engaged. Surgery was completed by resection of the frayed ends, reparation of the tendon, and insertion of the terminal end into the trough. At 6 months postoperative, a modified Mandelbaum and Pavanini clinical assessment indicated five excellent and two good outcomes. There were no cases of deep of superficial wound infection or skin necrosis. Despite the small number of patients and the short follow-up period, the authors believe this technique shows promise and that in selected cases the use of titanium anchors can facilitate the task of the surgeon and enable patients to return to normal and sports activities within 5 months after surgery.
