Cervicocranial syndrome or (craniocervical junction syndrome, CCJ syndrome) is a combination of symptoms that are caused by an abnormality in the cervical vertebrae leading to improper function of cervical spinal nerves. Cervicocranial syndrome is either congenital [1] or acquired. [2]
Patients who exhibit extreme joint hypermobility and connective tissue weakness as a result of Ehlers–Danlos syndrome or Marfan syndrome are susceptible to instabilities of the craniocervical junction; thus they are at risk for acquiring a Chiari malformation. Headache, neck pain, unsteady gait usually during childhood [4] 1.5
Craniocervical instability is more common in people with a connective tissue disease, including Ehlers-Danlos syndromes, [1] osteogenesis imperfecta, and rheumatoid arthritis. [2] It is frequently co-morbid with atlanto-axial joint instability, Chiari malformation , [ 3 ] or tethered spinal cord syndrome .
One study found that male German Shepherd Dogs with a lumbosacral transitional vertebra are at greater risk for cauda equina syndrome, which can cause rear limb weakness and incontinence. [ 10 ] The significance of transitional vertebrae has been questioned by one study finding similar prevalence in the general population as those with low back ...
These patients tend to neglect the opposite side of their lesion, based on the midline of the body, head, or retina. [20] For example, in a gap detection test, subjects with egocentric hemispatial neglect on the right side often make errors on the far right side of the page, as they are neglecting the space in their right visual field. [21]
Tietze syndrome is a benign inflammation of one or more of the costal cartilages. It was first described in 1921 by German surgeon Alexander Tietze and was subsequently named after him. The condition is characterized by tenderness and painful swelling of the anterior (front) chest wall at the costochondral (rib to cartilage), sternocostal ...
Transverse fracture: This type divides the base of the skull into a front and rear half. It occurs from impact on either side of the head or from side-to-side compression. The fracture typically runs through the petrous portion of the temporal bones and the sella turcica, potentially affecting the pituitary gland. Blood from both ears often ...
Myasthenia gravis is an autoimmune disease of the neuromuscular junction which results from antibodies that block or destroy nicotinic acetylcholine receptors (AChR) at the junction between the nerve and muscle. [6] [7] [1] This prevents nerve impulses from triggering muscle contractions. [1]
