GRAZINA, Rita et al. Fractura por estrés del cuello del fémur en una niña hiperactiva tratada con metilfenidato: Reporte de caso. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2018, vol.83, n.1, pp.45-49. ISSN 1852-7434.

Stress fractures most commonly affect physically active individuals with normal bone, and they are rare in children with open growth plates. Even rarer are femoral neck stress fractures in pediatric age. Nevertheless, they constitute a very important entity due to the risk of severe complications, such as avascular necrosis. A seven-year-old girl, treated with methylphenidate, who suffered an atypical femoral neck stress fracture is presented. Patient complained of right inguinal pain without daily life activity limitations. The radiograph showed a stress femoral neck fracture, confirmed by CT imaging. Conservative treatment was instituted and the patient became asymptomatic after 4 weeks. This case report alerts the clinicians about this rare entity that might be misdiagnosed. Recent research also suggests a possible involvement of drugs, such as methylphenidate, in bone demineralization, which might constitute a possible risk factor for fractures.
