II. Precautions

  1. Hip XRay may miss non-displaced Femoral Fractures
    1. Consider MRI or CT for negative XRay with higher index of suspicion

III. Imaging: Views

  1. Standard Views
    1. Anteroposterior Pelvis XRay (AP Pelvis XRay)
    2. Cross-Table Lateral Hip XRay
  2. Hip Avascular Necrosis
    1. Frog-leg Xray
  3. Hip Stress Fracture
    1. Maximal internal rotation hip

IV. Evaluation: Findings

  1. Hip Stress Fracture
    1. Trace medial and lateral cortical margins of the femoral neck
      1. Follow S-shaped curve (where femoral head meets the femoral neck)
      2. Observe for sharp angle along the S-curve suggestive of Stress Fracture
    2. Trace medial (compressive) and lateral (tensile) trabecular lines through femoral shaft and into femoral head
      1. Observe closely for subtle disruptions in trabecular lines suggestive of Stress Fracture
  2. Hip Osteoarthritis
    1. Osteophytes (at acetabulum or femoral head)
    2. Subchondral cysts
    3. Bony sclerosis
  3. Hip Avascular Necrosis
    1. Crescent sign (inconsistently seen on Xray)
      1. Femoral head flattening of the superior aspect
      2. Subchondral Fracture parallel to articular surface
  4. Other findings
    1. Hip lesions (e.g. tumors)
