Stress Fractures
Diagnosis of Stress Fractures
X-ray or bone scan Standard x-rays are recommended but may be normal until a callus forms 2 to 3 weeks after the injury. Technetium diphosphonate bone scanning or MRI may be necessary for early diagnosis. Women with stress fractures of the proximal femur or pelvis may have undiagnosed osteopenia and may require additional testing (eg, Diagnosis .)
