Type II—Long fusion below C2 with an abnormal occipital-cervical junction. Similar to the C2-C3 fusion of McRae and could be viewed as a more elaborate variation. Flexion , extension, and rotation are all concentrated in the area of an abnormal odontoid process or poorly developed ring of C1 which cannot withstand the effects of aging.
Conservative treatment of craniocervical instability includes physical therapy [10] [11] [better source needed] and the use of a cervical collar to keep the neck stable. Cervical spinal fusion is performed on patients with more severe symptoms. [citation needed]
As a result of having congenital Klippel-Feil syndrome, the spinal anatomy of the individual will present abnormal fusion of any two of the seven cervical bones in the neck. [13] This is considered to be an anomaly of cervical bones. [14] It affects the functioning of cervical spinal nerves (C1 - C8) because of compression on the spinal cord.
Spinal fusion, also called spondylodesis or spondylosyndesis, is a surgery performed by orthopaedic surgeons or neurosurgeons that joins two or more vertebrae. [1] This procedure can be performed at any level in the spine (cervical, thoracic, lumbar, or sacral) and prevents any movement between the fused vertebrae.
The exact prevalence of the disorder is not known; several family and population studies show that as many as 25% of cervical dystonia patients have relatives that are undiagnosed. [29] [30] Studies have shown that spasmodic torticollis is not diagnosed immediately; many patients are diagnosed well after a year of seeking medical attention. [1]
Cervical spinal stenosis is one of the most common forms of spinal stenosis, along with lumbar spinal stenosis (which occurs at the level of the lower back instead of the neck). Thoracic spinal stenosis, at the level of the mid-back, is much less common. [2] Cervical spinal stenosis can be far more dangerous by compressing the spinal cord.
Bone morphogenetic protein (rhBMP) should not be routinely used in any type of anterior cervical spine fusion, such as with anterior cervical discectomy and fusion. [2] [3] There are reports of this therapy causing swelling of soft tissue which in turn can cause life-threatening complications due to difficulty swallowing and pressure on the respiratory tract.
A variety of nerve types can be subjected to neurapraxia and therefore symptoms of the injury range in degree and intensity. Common symptoms of neurapraxia are disturbances in sensation, weakness of muscle, vasomotor and sudomotor paralysis in the region of the affected nerve or nerves, and abnormal sensitivity of the nerve at the point of injury.
