Fusión occipito-cervical en fractura inestable de atlas tipo Jefferson / Occipito-cervical fusion in unstable fracture of Jefferson type atlas

Resumen Las fracturas del Atlas representan el segundo tipo más común de lesiones de la columna cervical alta. Con este trabajo se persigue describir la fijación occipito-cervical como tratamiento de la fractura de atlas tipo Jefferson inestable. Se presenta paciente que sufre trauma raquimedular, después de aplicarle un minucioso examen físico y la tomografía axial computada de columna cervical se detecta una fractura tipo Jefferson de atlas con más de 7 mm de separación de sus fragmentos. Al ser esta una fractura inestable de la región cervical alta se decide realizar una fijación occipito-cervical como método de tratamiento de esta lesión. La evolución postquirúrgica del paciente transcurrió sin complicaciones (AU).

Summary Atlas fractures represent the second most common type of upper cervical spine injury. This work aims to describe the occipito-cervical fixation as a treatment for the unstable Jefferson-type atlas fracture. A patient suffering from spinal cord trauma is presented, after applying a thorough physical examination and the computed tomography of the cervical spine, a Jefferson type fracture of atlas with more than 7 mm of separation of its fragments is detected. As this is an unstable fracture of the upper cervical region, it was decided to perform an occipito-cervical fixation as a treatment method for this lesion. The postoperative evolution of the patient was uneventful (AU).

Traumatic Atlanto-Occipital Dislocation: A Case Report / 대한척추외과학회지

Survival after traumatic atlanto-occipital dislocation is rare. Severe persistent neurological deficits are common in the survivors, but early resuscitation and the use of the newer diagnostic techniques have contributed to improved outcomes. We present here the case of a 42 year old man with traumatic atlanto-occipital dislocation combined with a dens fracture, and the patient obtained good clinical results after we applied a Halo-vest and performed posterior fusion.

Malunion of the Odontoid Process Developing Cervical Myelopathy: A Case Report

Late-onset progressive myelopathy, years after odontoid fracture, is considered a rarity. Undiagnosed or untreated odontoid fractures may develop into nonunion or malunion, thereby leading to secondary delayed cervical myelopathy. We present a case of a 50-year-old man with malunion of odontoid fracture. We had a good result following one-staged posterior decompression and occipito-cervical fusion.
