Intramedullary calcaneal nailing is used to treat displaced intra-articular calcaneal fractures.
The main goal of the study was to assess the reduction of tomography and secondary goals were patient functional scores and complication rates.
The functional outcome and restoration of the radiographic parameters were evaluated post-operatively, at three months, at one year, and at the last follow-up. The morphology of the posterior facet was evaluated post-operatively, at one year and at the last follow-up by CTs.
Twenty-six patients were included. The mean follow-up was 2.8 years. The mean AOFAS-AHS was 79 at the last follow-up. The mean calcaneal height index and length rose respectively from 0.44 to 0.86 and 83 to 87 mm, and the width decreased from 50 to 46 mm.
The radiographic parameters were restored. The AOFAS-AHS was comparable with other series. This study confirms the efficiency of this procedure with lower rate of complications.
