Craniovertebral junction (CVJ) anomalies continue to be challenging for neurosurgeons because of the complex anatomy of this region. Craniovertebral junction (CVJ) anomalies can be congenital, developmental or due to malformation secondary to any acquired disease process. These anomalies can lead to cranial nerve compression, vertebral artery compression, and obstructive hydrocephalus. The aim of this study is to highlight the complications of instrumentation in the setting of syndromic craniovertebral junction (CVJ) anomalies. The craniovertebral junction (CVJ) consists of the occipital bone, foramen magnum, clivus, atlas (C1), axis (C2), and ligaments of the atlanto-occipital and atlantoaxial articulations.

If MRI or CT suggests vascular abnormalities, magnetic resonance angiography or vertebral angiography is done. If neural structures are compressed, treatment consists of reduction (traction or changes in head position to realign the craniocervical junction and thus relieve neural compression). After reduction, the head and neck are immobilized. The subject of craniovertebral junction anomalies has been under discussion and evaluation for over a century. Neurosurg Clin N Am. In this chapter, we focus on illustrating the lesions involving the craniovertebral junction. A number of classical reviews have attempted to clarify a variety of complex associated issues. Craniometric measurements used in radiologic assessment of CVJ anomalies include the Chamberlain line, Wackenheim clivus baseline, Welcher basal angle, and atlantooccipital joint axis angle. Congenital anomalies of the craniovertebral junction (CVJ) include conditions such as basilar invagination, assimilation of the atlas and other segmentation defects, atlantoaxial instability, and bony anomalies of the atlas or axis. Craniovertebral Junctional (CVJ) anomalies are developmental disorders that affect the skeleton and enclosed neuraxis at the junction of cranium and cervical spine.

There is 4.1% risk of vertebral artery injury during craniovertebral junction (CVJ) surgery (2,3). Complex surgical procedure or conservative management of this condition is the usual medical solution. Found inside – Page iiThis book will help guide decision-making in surgery using biologic and surgical principles to assist the planning and execution of surgery with available resources. When surgical treatment is indicated for the patient with a craniovertebral anomaly, he needs special reassurance as an operation in the vicinity of the medullospinal junction, as with an operation in the neighborhood of the brainstem, carries risks to life, consciousness, breathing, limbs, and control over the passage of urine/stools. Less often, it is caused by birth defects. Introduction: Basilar invagination (BI) is a congenital craniocervical junction (CCJ) anomaly represented by a prolapsed spine into the skull-base that can result in severe neurological impairment. 1– 3 Because it may have several etiologies, it has been suggested that basilar invagination should be considered a radiographic finding and that efforts should be made to identify the underlying anomaly if possible. However, evidence suggesting superiority of FOB in patients with CVJ instability is lacking. Central to these skills is an understanding of how people with different patterns of paralysis perform motor tasks and the importance of differentmuscles for motor tasks such as: transfers and bed mobility of people wheelchair mobility hand ... 14 Joint “Jamming” as a Treatment for Atlantoaxial Dislocation and Basilar Invagination.
