With the increasing utilization and improved resolution of cervical magnetic resonance imaging, craniocervical injury is being more accurately defined as a spectrum of injury that ranges in severity from overt craniocervical disassociation to isolated injuries of one more of the craniocervical ligaments, which may also lead to craniocervical instability. 1 – 14 The majority of these cases are asymptomatic, with estimates of symptomatic disease ranging from 1% to 2%. These are the ligaments that hold the head onto the upper spine. Emergency Cross-sectional Radiology is a practical aide-memoire for emergency medicine physicians, surgeons, acute care physicians and radiologists in everyday reporting or emergency on-call environments. Nagashima C, Kubota S (1983) Craniocervical abnormalities. In CCI the ligamentous connections of the craniocervical junction can be stretched, weakened or ruptured. A basion-dens distance of >12 mm on radiographs and >8.5 mm on CT is suggestive of craniocervical instability. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Craniocervical Junction Injuries 2Advanced Radiology Services, Grand Rapids, MI.

The clinical significance of these findings requires further elaboration. (c.) Mid sagittal T2W MR image; clivus- CT of the Craniocervical junction. These are considered grossly unstable injuries since the rotational and shearing forces at the craniocervical junction disrupt the ligamentous continuity of the tectorial membrane, the alar ligaments, and the transverse ligament. Basi Lateral radiographs of the craniocervical region, taken with the neck in flexion and extension (Figure 6A and B), have long been the primary studies for evaluation of craniocervical instability and possible cord compression (4). Contour lines on a lateral radiograph of the cervical spine. Pediatr Neurosurg 31: 71-77. Thus, there is loss of atlanto-axial continuity, and resultant separation. Questions about craniocervical instability (CCI), tethered cord, and other mechanical conditions as they might relate to myalgic encephalomyelitis (ME/CFS) ... Interestingly, radiology errors are surprisingly common! To learn more, see my video below: Join us for a free Regenexx webinar. Panjabi M, Dvorak J, Crisco J, et. Background A wide spectrum of structural changes in the elements of craniocervical junction in patients with ankylosing spondylitis (AS) has been recently described in a retrospective study using computed tomography [1]. Craniocervical Instability (CCI) is a structural instability of the craniocervical junction. So, the written report is meaningless for this purpose. High energy trauma results in a tear of the tectorial membrane and alar ligament at the craniocervical junction. Occipitoatlantal Dislocation Traumatic occipitoatlantal dislocation (OAD) is a severe ligamentous injury of the craniocervical junction. This brand-new volume in the best-selling "Case Review" series uses more than 200 case studies to challenge your knowledge of a full range of topics in emergency radiology, including MDCT-A of vascular injury, CT and MR of spinal injuries, ... The major ligaments involved are the Alar, Transverse and Accessory ligaments. "This book was written to teach people with Ehlers-Danlos Syndrome (EDS) how to systematically progress through an exercise program to allow their muscles to support many joint subluxations commonly associated with this genetic disorder. 2Department of Radiology, Medical School, University of Thessalia, Larissa, ... Craniocervical (CC) region’s ligaments play an impor- tant role in the stability, the mobility and the rotation of ... neck pain and may lead to instability and altered mobility : Flexion, extension, and lateral bending of the upper cervical spine in response to alar ligament transections. The distance between the C2 and C3 spinous processes is physiologically smaller than in the other segments. These are considered grossly unstable injuries since the rotational and shearing forces at the craniocervical junction disrupt the ligamentous continuity of the tectorial membrane, the alar ligaments, and the transverse ligament. Thus, there is loss of atlanto-axial continuity, and resultant separation. In the patient community, the term “CCI” is often used in reference to both Craniocervical Instability and Atlantoaxial Instability . This book addresses all pain imaging aspects related to both the central nervous system and the body (thorax, abdomen and pelvis), thus updating the international literature on the topic. On January 31, 2017 I went to Florida and met Dr.Franck. RSNA Cookie Policy. Lateral Neck X-ray. Craniocervical instability diagnosis Craniocervical instability diagnosis is given by performing an Upright Magnetic Resonance Imaging (MRI) that allows evaluating the craniocervical junction in an upright position as well as the evaluation of the patients’ anatomy in flexion & extension and neck rotation. For interesting perspectives and emerging standards in diagnosing these issues, here’s an interesting article including the important measurements. Now in its 4th Edition, this bestselling volume in the popular Requisites series, by Drs. Rohini Nadgir and David M. Yousem, thoroughly covers the extensive field of neuroradiology in an efficient and practical manner. This practical handbook covers the diagnosis and management of fractures in adults and children. Craniocervical instability (CCI) is a type of loose ligament condition in EDS that results in injury to the nervous system. Fractures of the tip of the dens or of the occipital condyles may be associated with alar ligament insufficiency. Subarachnoid hemorrhage and epidural hematoma may accompany injuries to the craniocervical junction and should be sought on CT scans of both the cervical spine and cranium. The cervical spine consists of the first seven vertebrae of the spinal column, C1-C7. Note that CCI stands for Craniocervical INSTABILITY, meaning that this is a movement-based concept. Other methods for detecting craniocervical junction injury using radiographs include the Powers ratio and the atlantodental interval. Structural abnormalities may have a dynamic element and thus may not be captured in a recumbent MRI. The Powers ratio is the ratio of the distance between the basion and the posterior spinolaminar line of C1 (yellow line) and the distance between the opisthion and the anterior arch of … This issue of Acta Neurochirururgica presents the latest surgical and experimental approaches to the craniovertebral junction (CVJ). • Build a large Craniocervical Junction Instability community. It is a transition zone b/w a mobile cranium & relatively rigid spinal column. AAS is characterized by a loss of stability between the C1 and C2 caused by either traumatic or nontraumatic causes [1]. This study found a miss rate of 43.6%. See more ideas about ehlers danlos syndrome, hypermobility, spinal. Neck pain is a prominent feature. This chapter reviews the anatomy of the craniocervical junction and discusses the elements involved … Jeff Wood’s remarkable recovery from severe ME/CFS following spinal surgery to correct craniocervical instability (CCI) and other problems shocked the ME/CFS community. The degree of spinal cord injury, (i.e., incomplete versus complete) has significant implications for whether urgent decompressive surgery is needed.

Chiari-like malformation (CM) appears to be the most common CJA encountered in dogs, and there has been a tremendous amount of clinical investigation into this disorder in recent years. Craniocervical junction disorders are abnormalities of the bones that join the head and neck. You'll need to request multiple hard copies of your MRI CDs. Although the radiographic findings in patients with craniocervical dissociation can be quite dramatic, they may be subtle or even absent on initial films. It provides clinical information for diagnosis and appropriate care for the patient, resulting in the perfect comprehensive text for spine surgeons. [5] Several ligaments and muscles control its motion and function and ensure the maximum mobility and … Hydrocephalus is a common manifestation of many diseases. Caring and treating a patient with hydrocephalus involve engagement and acquire a deep knowledge of anatomy, physiology, and technical details. Cervical spine injuries (including up to 50% of craniocervical injuries) are frequently missed at initial imaging in survivors of high-speed accidents. This can be an important factor in subsequent morbidity, with up to one-third of affected patients experiencing later neurologic deterioration (, 5 ). We present predictors for deficit using dynamic MRI of the craniocervical junction. Topic review and treatment recommendations. 1 = Anterior vertebral line 2 = Posterior vertebral line 3 = Spinolaminar line 4 = Posterior spinous line 5 = Wackenheim clivus line.
