The purpose of this study is to determine the efficacy of tibiotalocalcaneal arthrodesis by reamed intramedullary nail in the management of the distal tibia non-unions, associated with end-stage osteoarthritis of ankle and subtalar joints.
8 patients with radiographical and clinical diagnosis of non-union of the distal tibia have been treated with tibiotalocalcaneal arthrodesis by intramedullary retrograde nail and were retrospectively evaluated. Patients were radiographically and clinically evaluated preoperatively and at final follow-up regarding: satisfaction, AOFAS, VAS. Surgical technique is described.
Mean follow-up was 69.2 ± 23.2 months (range 48-108). In terms of subjective outcome, patients reported a highly satisfying result. All patients returned to daily activities, with an average time of 24.7 ± 8.7 weeks. 6 patients could return to their previous work activity, with an average time of 23.6 ± 6.3 weeks.
The procedure showed good results at final follow up. Consolidation was achieved in all the treated cases. Considering AOFAS and VAS scores at final follow-up, there was an evident improvement of the conditions of the patients.
