El aumento de la prevalencia de las heridas por arma de fuego determina que sea cada vez más frecuente observar pacientes con fragmentos de proyectiles retenidos en el cuerpo. En la mayoría de los casos se consideran inertes para el paciente; sin embargo, está indicada su extracción cuando se encuentran alojados dentro de la articulación. De esta forma, se busca evitar el daño provocado por la sinovitis reactiva, la lesión condral y la posible progresión a una artrosis postraumática. El objetivo de este trabajo es presentar a dos pacientes con fragmentos de proyectiles alojados a nivel de la articulación coxofemoral, uno impactado sobre la cabeza femoral y el otro en el fondo acetabular. En ambos casos, se realizó una luxación controlada anterior a través de un abordaje posterolateral asociado a una osteotomía trocantérica según Ganz, para extraerlos; de esta manera, se logra una visualización completa de la cabeza femoral y un acceso al acetábulo, resguardando al máximo la perfusión vascular. Se evaluaron los resultados clínicos de ambos pacientes.Palabras clave: Cadera; arma de fuego; luxación controlada. Nivel de Evidencia: IVBullet removal from the hip with a safe surgical anterior dislocation. Report of two cases AbstractThe increased prevalence of gunshot wounds makes it increasingly common to see patients with projectile fragments retained in the body. In most cases they are considered inert for the patient, but surgery is indicated to extract them, if they are located within the joint. In this way, we prevent damage from reactive synovitis, chondral injury and possible progression to post-traumatic osteoarthritis. The aim of this study is to report two cases in which the projectile fragments were at the level of the hip joint, one on the femoral head and the other in the acetabular fundus. In both patients, an anterior dislocation was performed through a postero-lateral approach associated with a trochanteric osteotomy described by Ganz. In this way a complete visualization of the femoral head and access to the acetabulum is achieved, thus protecting vascular perfusion. Clinical results were evaluated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
