          Abstract

          Resumen: Introducción: La luxación tibiofibular proximal (LTFP) es una lesión poco frecuente y no diagnosticada. De no ser tratada a tiempo, puede generar una sintomatología crónica de dolor e inestabilidad. La escasa evidencia disponible no entrega un protocolo de enfrentamiento ni consenso respecto a su manejo. Con el objetivo de asistir al enfrentamiento de esta lesión, se presenta una revisión de la literatura de una LTFP con reducción espontánea. Caso clínico: Hombre de 22 años consulta por dolor intenso en su rodilla derecha, posterior a caída en cuatrimoto. Al examen físico con aumento de volumen doloroso en cara lateral de la rodilla y pierna proximal, con movilidad completa y estable. Radiografías son informadas sin alteraciones. Se mantiene la sospecha clínica de LTFP, se continúa estudio con resonancia magnética (RM), la que es sugerente de LTFP. Dentro de las 24 horas de evolución, el paciente indica haber sentido un clank espontáneo en su rodilla afectada con cese completo de sintomatología. Se sigue al paciente por tres meses con RM de control, manteniendo una rodilla asintomática; examen físico y funcionalidad normal. Conclusión: El diagnóstico de las LTFP requiere un adecuado uso de imágenes. Su manejo consiste en una reducción cerrada de urgencia y de no lograrse, una reducción abierta, reparación y fijación interna. El pronóstico de las reducciones espontáneas es incierto, por lo que deben ser seguidas de forma seriada y en caso de recidiva, manejadas quirúrgicamente según el tiempo de evolución.

          Abstract: Introduction: Proximal tibiofibular joint dislocations (PTFJD) are uncommon and underdiagnosed injuries. Urgent reduction is mandatory to avoid chronic disfunction. The scarcely available literature does not present a unified management guideline. An acute PTFJD case report with spontaneous reduction and a review of the literature is presented, aiming to assist the diagnosis and management of this pathology. Case report: A 22-years old male presented to the emergency department with high intensity right knee pain after falling in a four-wheel motorcycle. The physical exam revealed a prominent painful mass on the lateral aspect of his knee and proximal leg. His range of motion and knee stability were unremarkable. X-rays were informed negative for musculoskeletal injuries. According to a sustained suspicion of PTFJD, the study was continued with a magnetic resonance imaging (MRI), which suggested PTFJD. During the following 24 hours, the patient referred he was entirely asymptomatic after feeling a loud «clank». He has been followed for three months with MRI, and remains asymptomatic with full functions. Conclusion: PTFJD diagnosis requires appropriate images. Urgent close reduction is mandatory; if unsuccessful, open reduction, primary repair and internal fixation are indicated. The prognosis of spontaneous reduction remains uncertain and requires a serial clinical evaluation. In the case of recurrence, the appropriate surgical management is indicated according to the elapsed time from the injury.

              Anatomic reconstruction of chronic symptomatic anterolateral proximal tibiofibular joint instability.

              Symptomatic chronic proximal tibiofibular joint subluxation is a pathology which is difficult to diagnose and treat. Surgical treatment has not been well defined. A report of two patients successfully treated with an anatomic reconstruction of the posterior aspect of the proximal tibiofibular joint is presented.
