A rare medley: concurrent ipsilateral femur head and neck fracture without hip dislocation

Simultaneous post-traumatic ipsilateral fracture of femur head and subcapital femur neck without hip dislocation is a rare presentation and easily missed on X-ray imaging. A 48 years old male, with a history of high-energy road traffic accident, presented to us with severe pain in the left hip region and inability to ambulate. Preliminary X-ray showed impacted subcapital fracture with varus angulation between femur head and neck. Further computed tomography (CT) scan imaging showed ipsilateral fracture of femur head and subcapital femur neck without hip dislocation. Primary total hip arthroplasty was performed. Presently patient is 5 years post-surgery and can ambulate without support. In conclusion, this fracture pattern, though rare, should be suspected in high-energy road traffic accident patients with shear forces acting at femur neck. It can best be diagnosed using 3D CT scan imaging. Primary total hip arthroplasty is an appropriate treatment in such patients.
