An 18-year-old female patient who is a cross-country runner presents with hip pain. She reports that she occasionally misses menstrual cycles. She denies any disordered eating habits and states that she does not worry about her weight. She has a body mass index of 18 kg/m. She is currently in the middle of her cross-country season but has had increasing groin pain that is present even when walking. Which of the following is the most likely diagnosis?
    • Labral tear
      • There are findings of the female athlete triad present, and pain in the hip is concerning for stress fracture.

 

    • Osteoarthritis
      • Since the patient is 18 years old, osteoarthritis is unlikely.

 

    • Osteonecrosis of the femoral head.
      • There are findings of female athlete triad present, and pain in the hip is concerning for stress fracture.

 

    • Femoral neck stress fracture
      • The patient’s symptoms suggest the female athlete triad. Hip pain even when walking may be indicative of a femoral neck stress fracture.
