Bilateral concomitant femoral neck stress fracture in a sedentary patient with anorexia nervosa

Abstract

A 27 years old sedentary woman presented bilateral femoral neck stress fractures after having clinically recovered from anorexia nervosa and was treated with bilateral internal fixation.

Conclusion: Although light exercise is usually considered after recovery from anorexia nervosa to improve bone quality, this case of a sedentary patient suggests that weight gain, per se, could increase the stress fracture risk. Because of the physiological and psychological characteristics, these patients should be treated with a multi-disciplinary approach.

Keywords: Anorexia nervosa; Bilateral femoral neck stress fracture; Hip fracture.
