Hip Trauma
A 28-year-old male is brought to the emergency department after a motor vehicle collision (dashboard injury). He presents with his right hip flexed, adducted, and internally rotated, with severe pain and inability to move his leg. AP pelvis radiograph confirms a posterior hip dislocation. Closed reduction is achieved successfully within 4 hours in the operating room under general anesthesia. Post-reduction CT reveals a femoral head fracture with a fragment involving 35% of the weight-bearing dome superior to the fovea. There is no associated femoral neck or acetabular fracture.
