FINDINGS

Supine AP radiograph of the pelvis (Fig. 92A) demonstrates a dislocated right hip, with marked superior displacement of the femoral head; the right femur is internally rotated relative to the left. There is a vertically oriented fracture of the posterior acetabular wall. Axial CT image of the pelvis at the level of the right femoral head following attempted reduction (Fig. 92B) demonstrates partial reduction with persistent posterior and superior subluxation. Two large intra-articular osseous bodies are present. Sagittal CT image through the right hip (Fig. 92C) demonstrates posterior subluxation of the femoral head and both intra- and extraarticular bone fragments.
