Talar body fracture associated with unrecognised talocalcaneal coalition

We report the case of a talar body fracture occurring in association with a previously undiagnosed talocalcaneal coalition. A rotational injury during a football tackle produced a grossly deformed ankle that was reduced in the emergency department. The unusual appearance of the medial sub-talar region on plain radiographs prompted further imaging by computerised tomography, which confirmed an osseous talocalcaneal coalition. Operative findings included a talar body fracture that could only be reduced after excision of the osseous coalition. The fracture was reduced and fixed. The patient made a good postoperative recovery with favourable AOFAS scores in the medium term at 1 year.
