Mosca M, Caravelli S, Fuiano M, et al. - In this research, the efficacy of tibiotalocalcaneal arthrodesis was ascertained by reamed intramedullary nail in the management of the distal tibia non-unions, correlated with end-stage osteoarthritis of ankle and subtalar joints. Researchers retrospectively examined eight patients with radiographical and clinical diagnosis of non-union of the distal tibia have been treated with tibiotalocalcaneal arthrodesis by intramedullary retrograde nail [mean follow-up was 69.2 ± 23.2 months (range 48–108)]. They presented surgical technique. At final follow up, the technique exhibited good outcomes. In all the treated cases, consolidation was achieved. At final follow-up, considering AOFAS and VAS scores, a significant improvement of the conditions of the patients was noted.
