II. Risk Factors
- See Stress Fracture
- Similar risks to Pubic Ramus Stress Fracture (military recruits, distance runners)
III. Symptoms
- Groin Pain or anterior thigh pain
- Provoked by activity (weight bearing)
- Relieved with rest
IV. Signs
- Antalgic Gait
- Pain on internal hip rotation
V. Imaging
-
Hip XRay
- XRay changes lag symptoms by 2-4 weeks
- MRI preferred over nuclear bone scan
- High Test Sensitivity (similar to bone scan)
- High Test Specificity (better than bone scan)
VI. Management
- Risk Modification
- See Stress Fracture
- Image the opposite hip if Stress Fracture is found (bilateral Hip Stress Fractures are common)
- Inferior Femoral Neck Stress Fractures (medial, compressive or compression side)
- Superior Femoral Neck Stress Fractures (lateral, tensile or tension side)
- Risk of complete Fracture or Hip Avascular Necrosis
- Open reduction and internal fixation recommended
