A patient with a posterior dislocation of the hip has an associated fracture of the femoral head, and radiographs also show a fracture of the femoral neck. In the Pipkin classification, this injury is:
- A Pipkin Type I
- B Pipkin Type II
- C Pipkin Type III ✓
- D Pipkin Type IV
Correct answer: C. Pipkin Type III
Explanation
The Pipkin system grades femoral head fractures accompanying hip dislocation: Type I lies below the fovea centralis, Type II extends above the fovea, Type III is any head fracture combined with a femoral neck fracture, and Type IV adds an acetabular fracture. The presence of the femoral neck fracture places this case squarely in Type III.
