Background The upper cervical region is a complex anatomical structure. Myodural bridges between posterior suboccipital muscles and the dura might be important explaining conditions associated with the upper cervical spine dysfunction such as cervicogenic headache. This cadaver study explored the upper cervical spine and evaluated the myodural bridges along with position of spinal cord in response to passive motion of upper cervical spine. Methods A total of seven adult cadavers were used in this exploratory study. The suboccipital muscles and nuchal ligament were exposed. Connections between the Rectus Capitis Posterior major/minor and the Obliquus Capitis minor, the nuchal ligament, posterior aspect of the cervical spine, flavum ligament and the dura were explored and confirmed with histology. The position of the spinal cord was evaluated with passive motions of the upper cervical spine. Outcomes In all cadavers connective tissues attaching the Rectus Capitis Posterior Major to the posterior atlanto-occipital membrane were identified. In the sagittal dissection we observed connection between the nuchal ligament and the dura. Histology revealed that the connection is collagenous in nature. The spinal cord moves within the spinal canal during passive movement. Discussion The presence of tissue connections between ligament, bone and muscles in the suboccipital region was confirmed. The nuchal ligament was continuous with the menigiovertebral ligament and the dura. Passive upper cervical motion results in spinal cord motion within the canal and possible tensioning of nerve and ligamentous connections.

Abstract For the past 20 years, the transoral approach to the upper cervical spine has been utilized for odontoid fractures, the removal of an abnormal odontoid process, decompression of basilar impression, and biopsy or resection of nasopharyngeal or metastatic tumors. The effectiveness and safety of this procedure is well documented. Use of the surgical microscope adds to the efficiency and safety of the procedure. We are reporting a case of fusion of the odontoid base to the anterior arch of the atlas. To our knowledge, this entity has not been described previously. The spinal cord was protected by an initial posterior fusion of C-1, C-2, followed in 10 days by a tracheostomy and the transoral removal of the anterior C-1 arch and the abnormal dens. Because the medical history did not reveal a source of trauma, it is supposed that the patient had malunion of the odontoid process to C-2, with subsequent migration and fusion of the dens to the C-1 arch.

Serious Injury

Neck pain and cervicalgia are common following concussion. The cervical spine should be carefully examined in any individual who has sustained a concussion, because neck pain may be a sign of more serious underlying cervical spine injury. Even when a more serious injury has been ruled out, it is noteworthy that the cervical structures are vulnerable to stress and injury at their end range of motion, and such motion occurs commonly in an accelerated fashion with concussion. Further, cervical spine injury may cause faulty proprioceptive input from the upper cervical spine, resulting in vestibular symptoms. Cervicalgia is a source of persistent symptoms following concussion and frequently manifests with dizziness and cervicogenic headache. Individuals with persistent symptoms of cervicalgia or cervicogenic headache may benefit from a combination of physical therapy and vestibular therapy.

Four cases of cervical "subluxation" have been presented due to muscle spasm in the cervical region, which occurred during an upper respiratory infection. This syndrome differs from the atlanto-axial subluxation. Roentgenograms in the diagnosis of this condition may lead to erroneous diagnosis and treatment. The normal anatomic and functional ranges of the cervical spine were studied and are discussed. The degree of mobility of the cervical spine is greater than previously assumed.

Primary Impact

ObjectivesMost biomechanical research on brain injury focuses on direct blows to the head. There are a few older studies that indicate craniocervical stretch could be a factor in concussion by causing strain in the upper spinal cord and brainstem. The objectives of this study are to assess the biomechanical response and estimate the strain in the upper cervical spine and brainstem from primary impact to the chest in American football.MethodsImpact testing was conducted to the chest of a stationary unhelmeted and helmeted anthropomorphic test device (ATD) as well as the laboratory reconstruction of two NFL game collisions resulting in concussion. A finite element (FE) study was also conducted to estimate the elongation of the cervical spine under tensile and flexion loading conditions.ResultsThe helmeted ATD had a 40% (t=9.84, p<0.001) increase in neck tensile force and an 8% (t=7.267, p<0.001) increase in neck flexion angle when compared with an unhelmeted ATD. The case studies indicated that the neck tension in the injured players exceeded tolerable levels from volunteer studies. The neck tension was combined with flexion of the head relative to the torso. The FE analysis, combined with a spinal cord coupling ratio, estimated that the strain along the axis of the upper cervical spinal cord and brainstem was 10%–20% for the combined flexion and tension loading in the two cases presented.ConclusionStrain in the upper spinal cord and brainstem from neck tension is a factor in concussion.

abstract A surgical approach to the clivus and anterior spine from C-1 to the upper part of C-5 is described. It is a direct approach that provides a wider and longer exposure than does the transoral approach. Despite the seemingly radical incision, the cosmetic deformity and functional loss are minimal. This approach is useful for the surgical treatment of a variety of processes that are situated ventral to the upper cervical spinal cord and the cervicomedullary junction.

Clinical Overview

Cervicogenic headache is a headache arising from painful dysfunction of the upper cervical spine. This paper reviews current literature on the anatomy, etiology, clinical presentation and differential diagnosis of cervicogenic headache. Lower cervical spine levels and cervical soft tissue components will be incorporated where they have a direct influence on the upper three segments.
