Abstract

The incidence of femoral head fracturesafter posteriorhip dislocation is approximately 5-15%, and femoral head fractures are highly associated with posterior dislocation. Femoral head fractures can cause avascular necrosis of the femoral head or post-traumatic osteoarthritis; therefore, diagnosis and appropriate treatment is important. We present a case of femoral head fracture without hip dislocation, as well as a literature review.

  Fig. 1 The schematic of injury mechanism.

  Fig. 2 Initial both hip Anteroposterior (AP) view and Rt. axial images show small bony fragment (black arrow) at the femoral neck and linear fracture line (white arrow) at the Rt. sup. ramus.

• 

  Fig. 3 (A) The follow-up both hip AP x-ray at 1 month reveals the same finding of Fig. 1. (B) The frogleg lateral view at 2 months.

  Fig. 4 (A) Pelvis CT image showing Pipkin type 2 femoral head fracture. (B) Impacted and incomplete fracture. (C) Right superior ramus fracture. (D) The 3D CT image of femur demonstrates the fracture line is along with the margin of posterior rim of acetabulum.

• 

  Fig. 5 (A) The follow-up both hip AP x-ray at 3 months shows fracture healing of Rt. superior ramus. (B) The bone SPECT image at 3 months shows increased uptake in right femur head and right pubis and no cold uptake lesion at the femoral head.

• 

  Fig. 6 The 6 months right hip MRI shows healing state of fracture and has no evidence of avascular necrosis of femoral head.

• 

  Fig. 7 The 12 months follow-up both hip AP x-ray shows no evidence of avascular necrosis of femoral head or post-traumatic osteoarthritis.
