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