A diferencia de la fractura cerrada de fémur proximal, la incidencia de fracturas expuestas se encuentra en la población joven de entre 15 y 30 años de edad. Dentro de las complicaciones que podemos observar en estas fracturas se encuentra la osteonecrosis avascular (NAV) de la cabeza femoral, la cual se define como la interrupción del aporte sanguíneo a la cabeza femoral, ya sea por trauma, infección, alcoholismo o uso de esteroides, ocasionando necrosis ósea, colapso articular y osteoartrosis. El tratamiento dependerá de la presentación del caso, la edad del paciente y el tiempo en hacer el diagnostico. Se presenta el caso clínico de un paciente de 16 años de edad el cual ingresa al servicio de urgencias con diagnóstico de herida por arma de fuego a nivel de cadera izquierda. Se realiza lavado quirúrgico y reducción cerrada más fijación interna con clavo centro medular. Se da un seguimiento clínico y radiográfico por 3 años observando la evolución de la fractura y la subsecuente necrosis avascular que presenta el paciente.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: The clinical presentation of a proximal femoral fracture is completely different between young and adult patients. Unlike closed proximal femoral fractures, the incidence of exposed fractures is found in the young population between 15 and 30 years of age. Osteonecrosis of the femoral head is one the complications we can find in this type of fractures. Avascular necrosis (AVN or osteonecrosis) is defined as the interruption of blood supply to the femoral head due to trauma, infection, alcohol or steroid use, resulting in bone necrosis, joint collapse and osteoarthrosis. The treatment will depend on the clinical presentation, age of the patient and when the diagnosis is made. This is a case report of a 16-year-old patient with a gunshot wound on the hip. Surgical cleansing and closed reduction plus internal fixation with a nail in the center of the spine were performed. A 3-year clinical and radiographic follow up was made, observing the evolution of the fracture and the subsequent avascular necrosis that the patient presented.]]></p></abstract>
