Three-dimensional computed tomography analysis and functional results of calcaneal fractures treated by an intramedullary nail

Int Orthop. 2019 Dec;43(12):2839-2847. doi: 10.1007/s00264-019-04381-3. Epub 2019 Aug 1.


Background: 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.

Methods: 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.

Results: 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.

Conclusion: 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.
