Simultaneous bilateral femoral neck fractures secondary to epileptic seizures: treatment by bilateral total hip arthroplasty.

Simultaneous bilateral femoral neck fracture following an epileptic seizure attack are rare. Open reduction and internal fixation remains the most used therapeutic option. Arthroplasty, carrying a high risk of dislocation is less often recommended. We report the favourable evolution of a 49-year-old man who benefited from a single stage bilateral total hip arthroplasty operation for his simultaneous bilateral, femoral neck fractures secondary to a generalized seizure. This nonconsensual choice, in this case, was justified on multiple grounds: surgical care delay longer than 48 hours, substantial bone displacement, borderline bone quality, adequate antiepileptic treatment efficacy and tolerance. A ceramic-on-ceramic bearing surfaces couple, a large-diameter head and a cementless implantation design together should be able to provide an acceptable longevity in a young and active patient.
