Summary:

Description
  • Radiopaedia case ID: 30134
  • Image ID: 7663477
  • Image stack position: 2/19
  • Plane projection: AX T1
  • Study findings: Multiplanar multi-sequence MRA imaging of the right hip performed following intra-articular injection of 0.01% gadolinium solution. Adequate joint distension achieved. Over-coverage of the femoral head by the bony acetabulum with pincer type femoroacetabular impingement. Abnormal contour at posterior and inferior head/neck junction with an inferiorly projecting bony bump/osteophyte. The superior labrum is blunted with superior labral tear (11-1 o'clock). In addition, there is a tear of the posterior labrum (3 - 5 o'clock). There is loss of articular cartilage superiorly with small subchondral cysts medially. Normal appearance of the iliopsoas, gluteal, and hamstring tendons. No muscle abnormality. No evidence of trochanteric bursitis. Conclusion: Pincer type FAI with anterosuperior labral tear and posterior labral tear. Early degenerative changes are present.
  • Modality: MRI
  • System: Musculoskeletal
  • Findings: CT Pelvis: Bilateral protrusio acetabuli results in over-coverage of both femoral heads and a pincer type of femoro-acetabular impingement. Coronal images best show the medialisation of the medial wall of the acetabulum with the femoral heads entirely covered by acetabulum.
