Summary
Cervical vertigo (CV) is often diagnosed in patients with degenerative cervical myelopathy (DCM). However, this study found no evidence supporting CV, attributing vertigo to other causes in all DCM patients.
Area of Science:
- Neurology
- Orthopedics
Background:
- Cervical vertigo (CV) is a debated condition with uncertain prevalence.
- Degenerative cervical myelopathy (DCM) can present with vertigo, raising questions about CV's role.
Purpose of the Study:
- To determine the prevalence and causes of vertigo in severe DCM patients.
- To investigate the specific contribution of cervical factors to vertigo in this population.
Main Methods:
- 38 DCM patients were assessed for vertigo using questionnaires and the cervical torsion test.
- Vertebral artery ultrasound was performed to rule out stenosis.
- Comprehensive diagnostic work-up was conducted for all vertigo cases.
Main Results:
- 47% of DCM patients reported vertigo.
- Identified causes included orthostatic dizziness (22%), hypertension (14%), BPPV (11%), and psychogenic dizziness (3%).
- No patients tested positive for CV via the cervical torsion test or showed significant vertebral artery stenosis.
Conclusions:
- Vertigo is common in DCM patients, but not attributable to cervical spine issues.
- The findings suggest cervical vertigo is over-diagnosed, with other conditions being the primary causes.

01:15Equilibrium and Balance
5.3K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

01:29The Vestibular System
41.7K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

01:16Vertebral Column: Regions and Curvature
5.1K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

01:28Articulations of the Vertebral Column
2.6K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
