Tibiotalocalcaneal arthrodesis with a triple-bend intramedullary nail (A3)-2-year follow-up in 60 patients

Abstract

Background: The aim of the study was to analyze the clinical aspects including 2-year follow-up of tibiotalocalcaneal arthrodesis (TTCA) with a triple-bend retrograde intramedullary nail (A3, Stryker, Airview Boulevard, MN, USA).

Methods: All patients with TTCA with A3 between October 18, 2011 and April 29, 2013 were included. Visual Analogue Scale Foot and Anklenkle (VAS FA), indications for surgery, details of surgery, radiographic measurements, and complications were analyzed.

Results: A total of 66 patients were included. The mean VAS FA was 29.6. Most common indications were arthrosis (n=43; 65%) and deformity (n=36; 55%). The accuracy of correction and implant position was 9.4 (maximum 10) on average. Infection rate was 3% (n=2). Sixty (91%) patients completed follow-up: VAS FA 59.9, fusion rate 100%, high accuracy of correction and implant position.

Conclusions: TTCA with the A3 implant system showed accurate correction and implant position. Two-year follow-up in 60 patients (91%) showed good clinical outcome scores and 100% fusion rate.
