"Jefferson fracture"

Traumatic posterior atlantoaxial dislocation with associated C1 Jefferson fracture and bilateral vertebral artery occlusion without odontoid process fracture or neurological deficit. Traumatic atlantoaxial dislocation (AAD) is usually associated with fatal high-velocity road traffic accidents (Xu et al. in Medicine (Baltimore) 94:e1768, 2015). There are few reports of survival following posterior AAD without odontoid fracture (Xu et al. 2015; Zhen et al. in Arch Orthop Trauma Surg 131:681-685, 2011; de Carvalho and Swash in Handb Clin Neurol 119:435-448, 2014). We present a previously undescribed case of posterior AAD associated with a C1 Jefferson fracture but no odontoid fracture and bilateral vertebral artery occlusion without neurological deficit. The presence of bilateral vertebral

Bipartite Atlas or Jefferson Fracture? A Case Series and Literature Review. Case series and literature review. We present a new case of a C1 anterior arch fracture after suboccipital craniotomy and C1 laminectomy to add to 3 previously reported cases, thus increasing awareness of this postoperative complication. We also present 2 adult cases of presumably congenital bipartite atlas . The radiographical similarity of these cases raises the possibility of a traumatic cause for some instances of bipartite atlas rather than a congenital defect. The bipartite atlas is a rare entity that has previously been presumed to represent a congenital variant. Its imaging appearance may be mistaken for a Jefferson fracture in the setting of trauma. The first case is a 4-year-old female who underwent

Combined Type II Odontoid Fracture with Jefferson's Fracture Treated with Temporary Internal Fixation An 18-year-old male presented after a motor vehicle rollover accident. Computed tomography (CT) scan confirmed the diagnosis of Type II odontoid fracture. Considering the patient's young age and the limitations of C1-C2 fusion including significant loss of cervical rotation, temporary internal

Complex developmental abnormality of the atlas mimicking a Jefferson fracture: Diagnostic tips and tricks Congenital atlas abnormalities are rare - often asymptomatic - findings, not requiring any specific treatment. They are frequently discovered, by chance, in trauma patients, in the course of the radiological work flow at the Emergency Department. In these cases they may represent a diagnostic challenge, since physicians are expected to differentiate them from complex C1 fractures (isolated Jefferson's fractures or associated with Anderson and d'Alonzo's fractures) requiring surgical treatment. Although difficult to identify, a correct diagnosis is mandatory in order to optimize the patient's treatment. In this article we report a case of congenital atlas abnormality, and discuss the tips

Occipital Neuralgia after Occipital Cervical Fusion to Treat an Unstable Jefferson Fracture In this report we describe a patient with an unstable Jefferson fracture who was treated by occipitocervical fusion and later reported sustained postoperative occipital neuralgia. A 70-year-old male was admitted to our center with a Jefferson fracture induced by a car accident. Preoperative lateral X-ray

intervertebral widening, and pseudo-Jefferson fracture, can adversely affect the accuracy of CT imaging interpretations [19]. Metrics, such as the condyle-C1 interval on CT or MRI in pediatric patients, have relatively high sensitivity (93%) but lack significantly in specificity depending on the choice of measurement cut-offs (18%–100%) [31,32]. Young children and those ranges from 81% to 100%, which is lower than in adults (97%–100%) [19]. Normal variants in children <8 years of age, such as pseudosubluxation of C2-C3, absence of lordosis, C3 vertebral wedged appearance, widening of the atlantodental interval, prevertebral soft-tissue thickening, intervertebral widening, and pseudo-Jefferson fracture, can adversely affect

CT or MRI will show fragmented body. * Stable but may impinge on anterior cord * Jefferson Fracture – an eponymous fracture for a British neurologist who described this fracture. I like to think perhaps he was a weekend cliff diver, as this fracture is often seen with shallow

View Media Gallery All C1 or atlas fractures can be treated with halo vest immobilization until fracture healing occurs.Odontoid fracturesOdontoid fractures are classified into three types as follows.Type IType I odontoid fractures are cephalad to the transverse ligament and are secondary to avulsion of alar ligaments. They rarely are associated anterior displacement of one vertebra on adjacent inferior vertebrae. * * Jumped facets with complete anterior displacement of proximal vertebrae. * * Atlantooccipital dislocation. * * Axial CT scan of increased atlantodens interval. * * Sagittal CT scan reconstruction that shows widening of atlantodens interval. * * Three-dimensional CT scan of C1. * * Axial CT scan of Jefferson

Traumatic posterior atlantooccipital dislocation with Jefferson and occipital condyle fractures: A case report. To the best of our knowledge, this is the first report on a case of a traumatic posterior atlantooccipital dislocation (AOD) with 3-part Jefferson and occipital condyle fractures. We report the case of a 60-year-old male with posterior AOD with 3-part Jefferson fracture and fracture of right occipital condyle. This injury occurred as a result of rolling down from a mountain. The patient complained of severe neck pain showing bony tenderness and ecchymosis in the high cervical area but did not show any neurologic abnormalities. Reconstructed computed tomography scans clearly demonstrated a 3-part Jefferson fracture and fracture of right occipital condyle, and posteriorly displaced

. These anomalies can occasionally mimic acute trauma (bipartite atlas versus Jefferson fracture, butterfly vertebra versus burst fracture), or predispose the affected individual to myelopathy. Accurate imaging interpretation of vertebral malformations requires knowledge of ageappropriate normal, variant and abnormal vertebral morphology and the clinical implications of each entity. This knowledge will improve

Developmental abnormalities of the craniocervical junction resulting in collet-sicard syndrome. Collet-Sicard syndrome describes the paralysis of cranial nerves IX-XII and is the most frequently reported neurologic complication associated with Jefferson fractures. As the lateral mass of the atlas is displaced laterally toward the styloid process and the stylohyoid ligament, the lateral mass

There were 16 compression and 10 transverse fractures, two Jefferson's fractures, one type II and two type III odontoid process fractures, and five fractures of the posterior spinal elements (including lamina and/or facet, three spinous process fractures, three transverse process

Two patients had associated spinal fractures in the thoracic spine. All the patients acquire solid bony fusion, including fusion of the associated cervical spinal fractures.

This fracture of all aspects of the C1 ring is associated with possible disruption of the transverse ligament of the atlas. Lateral projection may show a widened predental space and a fracture through the posterior arch of C1. Odontoid view shows this fracture from a Jefferson fracture.The transverse ligament and the anterior arch of C1 are not involved, making this fracture stable. Initial management involves the differentiation of this benign fracture from a Jefferson fracture. Once this is accomplished, only use of a cervical orthosis is required.Previous Next: Vertical (axial) Compression InjuryCommon injuries associated with a vertical
