Conditions in and around the hip

FAI - X-Rays, CT Scans & MR Arthrogram
  • Pelvis x-ray
  • CT scan
  • Femoroacetabular impingement (FAI) left hip with large impingement lesion
  • Early osteoarthritis


Pelvis X-Ray
  • Bilateral impingement lesions on pelvis x-ray
  • Patient only symptomatic on right side!


CT & 3D CT Scans
  • CT scan showing femoroacetabular impingement (FAI)
  • 3-D reconstructed CT scan showing femoroacetabular impingement


3-D reconstructed CT scan of patient with symptoms of femoroacetabular impingement


Diagnosis = Os acetabulare – a loose fragment of bone at the rim of the hip socket


MR Arthrogram of left hip
  • MR arthrogram of hip
  • Labral tear
  • Loss of sphericity of femoral head
  • Impingement lesion

Acetabular labrum

X-rays of FAI
  • Normal labrum seen at hip arthroscopy
  • Degenerate labral tear prior to treatment

Ligamentum Teres

  • Ligamentum teres partial tear viewed at hip arthroscopy prior to debridement

Articular cartilage

  • Cartilage damage is usually caused by trauma or wear and tear and varies in severity normal cartilage
  • Delaminated cartilage (cartilage peeling away from bone)
  • Degenerate flap tear (damaged cartilage)
  • Completely worn out cartilage exposing subchondral bone

Acetabular Microfracture



  • Widespread cartilage loss on the ball and socket
  • Degenerate tears of labrum and ligamentum teres
  • Rim and central osteophytes
  • Loose bodies


  • The lining of the hip joint becomes irritated and inflamed often by various conditions in the joint
  • It is associated with other conditions, but may be the main cause of pain
  • It is frequently debrided at hip arthroscopy
  • See at Hip Arthroscopy
