Spontaneous bilateral femoral neck fractures associated with a low serum level of vitamin D in a young adult.

Bilateral femoral neck fracture is an extremely rare injury in young adults. We report a young adult with bilateral femoral neck fracture after minimal stress. The current case did not demonstrate any abnormality on laboratory data, except for a low serum level of vitamin D(3). Although, in our case, the patient underwent bilateral femoral head arthroplasty, early diagnosis could have been helpful to avoid further displacement of the fracture and surgical treatment.
