Atlanto-occipital dislocation - Wikipedia
Atlanto-occipital dislocation, orthopedic decapitation, or internal decapitation describes ligamentous separation of the spinal column from the skull base. It is possible for a human to survive such an injury; however, 70% of cases result in immediate death.
Atlanto-occipital dissociation injuries - Radiopaedia.org
2022年11月17日 · Atlanto-occipital dissociation injuries are severe and include both atlanto-occipital dislocations and atlanto-occipital subluxations. The tectorial membrane and alar ligaments provide most of the stability to the atlanto-occipital joint, and injury to these ligaments results in instability due to low inherent osseous stability 3.
Atlanto-occipital dislocation - PMC
AOD is a highly unstable craniocervical injury, resulting from damage to ligaments and/or bony structures connecting the skull to the cervical spine. It is historically associated with significant neurological morbidity and mortality secondary to brainstem and upper cervical spinal cord injury.
Occipitocervical Instability - Spine - Orthobullets
2024年10月26日 · Acquired instability is treated with observation or occipitocervical fusion depending on the presence of neurologic deficits. intrinsic ligaments are located within the spinal canal and provide most of the ligamentous stability. They include:
Computed tomography (CT) imaging to deter-mine the CCI (condyle-C1 interval) in pediatric patients with potential atlanto-occipital disloca-tion (AOD) is recommended. If there is clinical or radiographic suspicion of AOD, CT of the craniocervical junction is recommended.
Atlanto-occipital dislocation: four case reports of survival ...
2003年12月13日 · Traumatic atlanto-occipital dislocation (AOD) is a rare cervical spine injury and in most cases fatal. Consequently, relatively few case reports of adult patients surviving this injury appeared in the literature.
Imaging of Atlanto-Occipital and Atlantoaxial Traumatic ...
2015年11月12日 · The imaging findings of important CCJ injuries, such as atlanto-occipital dissociation, occipital condyle fractures, atlas fractures with transverse ligament rupture, atlantoaxial distraction, and traumatic rotatory subluxation, are important to recognize in the acute setting, often dictating patient management.
