Pediatric Cervical Spine instability
Journal of Children's Orthopaedics, 2008Co-Authors: Ismat Ghanem, Samer El Hage, Rami Rachkidi, Fernand Dagher, Khalil Kharrat, Gabi KreichatiAbstract:Cervical Spine instability in children is rare but not exceptional and may be due to many factors. Although it mostly occurs at the upper Cervical Spine, all vertebrae from the occiput to T1 may be involved. It may be acute or chronic, occurring secondary to trauma or due to congenital anomaly, skeletal or metabolic dystrophy or rheumatoid arthritis. It can be isolated or associated with other musculoskeletal or visceral anomalies. A thorough knowledge of embryology, anatomy, physiology and physiopathology of the Cervical Spine in children is essential to avoid pitfalls, recognize normal variants and identify children at risk of developing Cervical Spine instability and undertake the appropriate treatment.

Congenital Anomalies of the Pediatric Cervical Spine
Seminars in Spine Surgery, 2011Co-Authors: Patrick O’toole, Lauren A. Tomlinson, John P. DormansAbstract:Understanding the complexities of congenital deformities of the Cervical Spine and their sequelae is greatly enhanced by knowledge of the development of the Cervical Spine. Although many of these deformities are asymptomatic, when encountered, it is important for the physician to identify potential problem patterns and to be aware of any associated systemic manifestations. In this article, we discuss Klippel-Feil syndrome, torticollis, os odontoideum, and congenital absent Cervical pedicle in detail but also other disorders that commonly involve the Cervical Spine. The presentation, investigation, and management of congenital Cervical Spine anomalies will also be discussed.

nontraumatic upper Cervical Spine instability in children
Journal of The American Academy of Orthopaedic Surgeons, 2006Co-Authors: Brian P D Wills, John P. DormansAbstract:Abstract The upper Cervical Spine begins at the base of the occiput, continues caudally to the C2-C3 disk space, and includes the occipitoatlantal and atlantoaxial joints. Nontraumatic upper Cervical Spine instability can result from abnormal development of osseous or ligamentous structures or from gradually increasing ligamentous laxity associated with connective tissue disorders. Such instability can lead to compression of the spinal cord during movement of the Cervical Spine. Establishing a correct diagnosis includes performing a thorough physical examination as well as evaluating radiographic relationships and measurements. Appropriate management of syndromes associated with instability of the upper Cervical Spine includes preventive care and recommendations for sports participation. Surgical treatment for the upper Cervical Spine includes a posterior surgical approach, used for instability, and the use of rigid plate implants, wiring, and bone graft materials to achieve a solid spinal fusion.

Cervical Spine disorders in infants and children.
Journal of The American Academy of Orthopaedic Surgeons, 1998Co-Authors: Lawson A B Copley, John P. DormansAbstract:The evaluation of children with Cervical Spine disorders requires an understanding of the anatomic and developmental features that are particular to the pediatric Spine. In this article, Cervical Spine developmental anatomy is briefly reviewed, along with common radiographic features of the pediatric Cervical Spine. The epidemiology, clinical presentation, and management of congenital Cervical anomalies are considered. The evaluation and management of pediatric Cervical trauma are also reviewed. Other disorders with common Cervical Spine involvement, such as skeletal dysplasias, connective tissue disorders, inflammatory arthritides, and storage disorders, are discussed.

Cervical Spine Injuries in the Athlete.
Journal of Bone and Joint Surgery American Volume, 2017Co-Authors: Gregory D. Schroeder, Alexander R. VaccaroAbstract:: Cervical Spine injuries are common and range from relatively minor injuries, such as Cervical muscle strains, to severe, life-threatening Cervical fractures with spinal cord injuries. Although Cervical Spine injuries are most common in athletes who participate in contact and collision sports, such as rugby and American football, they also have been reported in athletes who participate in noncontact sports, such as baseball, gymnastics, and diving. Cervical Spine injuries in athletes are not necessarily the result of substantial Spine trauma; some athletes have chronic conditions, such as congenital stenosis, that increase their risk for a serious Cervical Spine injury after even minor trauma. Therefore, physicians who cover athletic events must have a thorough knowledge of Cervical Spine injures and the most appropriate methods for managing them. Although Cervical Spine injuries can be career-ending injuries, athletes often are able to return to play after appropriate treatment if the potential for substantial reinjury is minimized.

Rheumatoid arthritis of the Cervical Spine.
The Spine Journal, 2004Co-Authors: Hoan Vu Nguyen, Paul A. Anderson, Steven C. Ludwig, Jeffery Silber, Daniel E. Gelb, Lawrence Frank, Alexander R. VaccaroAbstract:Abstract Background context Rheumatoid arthritis affects over 2 million patients in the United States. It is the most common inflammatory disorder of the Cervical Spine. The natural history is variable. Women tend to be more commonly involved than men. Atlantoaxial instability is the most common form of Cervical involvement and may occur either independently or concomitantly with cranial settling and subaxial instability. Cervical Spine involvement can be seen in up to 86% of patients and neurologic involvement in up to 58%. Myelopathy is rare but when present portends a poor prognosis. What is frustrating for clinicians treating these patients is that pain cannot be equated with instability or instability with neurologic symptoms. The goal is to identify patients at risk before the development of neurologic symptoms. Both radiographic and nonradiographic risk factors play an important role in the surgical decision-making process. Purpose We will describe the current concepts in rheumatoid arthritis of the Cervical Spine. Emphasis is placed on the natural history, anatomy, pathophysiology and decision-making process. Study design A review of the current concepts of rheumatoid arthritis of the Cervical Spine. Methods MEDLINE search of all English literature published on rheumatoid arthritis of the Cervical Spine. Results Rheumatoid arthritis of the Cervical Spine was first described by Garrod in 1890. The prevalence has been estimated to be 1% to 2% of the world's adult population. Despite its prevalence, the etiology of rheumatoid arthritis remains unknown. Because of its potentially debilitating and life-threatening sequelae in advanced disease, rheumatoid arthritis in the Cervical Spine today remains a high priority to diagnose and treat. Conclusions Many aspects of the natural history and pathophysiology of the rheumatoid Spine remain unclear. The timing of operative intervention in patients with radiographic instability and no evidence of neurologic deficit is an area of considerable controversy. Continued surveillance into the natural history of the rheumatoid Spine is required.

Transpedicle screw fixation of the Cervical Spine : Disorders of the Cervical Spine
Clinical Orthopaedics and Related Research, 1999Co-Authors: Steven C. Ludwig, David L. Kramer, Alexander R. Vaccaro, Todd J. AlbertAbstract:The use of posterior Cervical Spine fixation has become increasingly popular in recent years. Dissatisfaction with lateral mass fixation, especially at the cervicothoracic junction, has led Spine surgeons to use Cervical pedicle screw fixation for reconstruction in numerous Cervical Spine disorders. The biomechanical advantage of a three-column fixation device implanted to secure an unstable Cervical Spine has proven to be a valuable tool in the Spine surgeon's armamentarium. Successful placement of a pedicle screw in the Cervical Spine requires a sufficient three-dimensional understanding of pedicle morphology to allow accurate identification of the ideal screw axis. Variability in cadaveric based morphometric measurements used to guide the surgeon in the placement of a pedicle screw has raised legitimate concerns as to whether transpedicle fixation can be applied without significant neurovascular complications. The emergence of computer assisted image guidance systems may be implemented in the operative protocol to improve the accurate placement of a pedicle screw. The indications for placement of a pedicle screw in the Cervical Spine are beginning to evolve. Only surgeons experienced in transpedicle screw fixation and surgery of the Cervical Spine should perform this method of instrumentation.
