Abstract

Pelvic fractures result from high energy trauma and often associated with concomitant injuries. But, vertically unstable pelvic fractures combined with anterior dislocation of the hip is far less common. The traumatic dislocation of the hip is a true orthopedic emergency and it should be considered that a femoral head can be exposed to deteriorized vascularity. We report a case of vertically unstable pelvic fractures combined with traumatic anterior dislocation of the hip joint with the review of the literature.

Figure

• 

  Fig. 1 Initial pelvis AP (A) and inlet view (B) show anteroinferior dislocation of left femoral head, right pubic fracture and sacral fracture.

• 

  Fig. 2 Pelvis CT shows sacral fracture (Type I) (A), anteroinferior dislocation of left femoral head and right pubic fractures (B,C).

• 

  Fig. 3 Post reduction pelvis AP radiograph and pelvis CT show concentric reduction of left femoral head (A, B). Concentric reduction was maintained by skeletal traction (A).

• 

  Fig. 4 The first postoperative radiograph shows open reduction and internal fixation of the anterior ring of the pelvis by modified Stoppa approach.

• 

  Fig. 5 The second postoperative radiograph shows percutaneous iliosacral screw fixation under the CT guided for sacral fracture.

• 

  Fig. 6 Complete union of pelvic fractures (A)and no visible evidence of avascular necrosis of left femoral head (B) at the time of final follow-up, postoperative 2 years.
