The course is usually subacute and, although there are predisposing factors described, most patients do not present with them. Generally, joint fluid cultures are sterile since these microorganisms are very sensitive to contact with oxygen, so they require specific culture media. All of the above causes the diagnosis to be delayed, increasing the risk of long-term sequelae. However, the prognosis improves when treatment is started early. The case is presented of a 10-year-old patient who was admitted for 30 days due septic arthritis of the right hip caused by   Fusobacterium nucleatum During the admission, he required three surgical interventions, and completed 6 weeks of effective antibiotic therapy, with a good outcome and remaining asymptomatic at the current time.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN Las infecciones osteoarticulares por anaerobios son muy raras en los niños, siendo el género  Fusobacterium el que se aisla con más frecuencia. El curso suele ser subagudo y, aunque hay factores predisponentes descritos, la mayoría de los pacientes no los presenta. Generalmente, los cultivos de liquido articular son estériles ya que estos microorganismos son muy sensibles al contacto con el oxigeno, por lo que precisan medios de cultivo específicos. Todo lo anterior hace que el diagnóstico se retrase y que el riesgo de secuelas a largo plazo aumente. Sin embargo, el pronóstico mejora cuando el tratamiento se inicia de modo precoz. Por todo ello, presentamos el caso de un paciente de 10 anos con una artritis séptica de cadera derecha por  Fusobacterium nucleatum que permaneció ingresado 30 dias. Durante el ingreso precisó 3 intervenciones quirúrgicas y cumplió 6 semanas de antibioterapia efectiva, con buena evolución; permanece asintomático en el momento actual.]]></p></abstract>
