In cervical spondylosis , the cervical backbone , which is the spine of the cervix , and theintervertebral platter , which is the cartilage between the spines , are deformed with geezerhood , and osteochondral tissue paper called “ osteophytes ” increases and the neck hurts . In this condition , numbness , pain , or movement disorders in the upper limbs are called “ cervical myelopathy”.(1 )
What Are The First Symptoms Of Cervical Spondylosis?
Cervical spondylosis is a precondition in which disk bulges , ligament thickening , and osteophyte shaping occur due to age - related degeneration of thecervical magnetic disk , hook joint ( Luschka join ) , facet articulation , etc . When the nerve roots and spinal cord are pressed and damaged , neurologic symptoms occur . It is the most common disease in patients with indifference in work force . Symptomatic cervical spondylosis is more probable to develop after the age of 50 , and it is often cover that the relative incidence in man is about twice that in women .
When the spinal cord flattens due to compaction , pathologic changes occur in the grizzly subject . The anterior tusk first flattens , and when it becomes more advanced , it form a cystic cavity in the ventrolateral part of the posterior chord from the central hoary thing such as the prior trumpet , intermediary , and dorsal horn.(2 )
Clinical Symptoms Of Cervical Spondylosis
Radiculopathy : Radiculopathy often set out withradiculopathyin the cervical , shoulder joint , and upper extremity on one side . This nerve root pain is aggravate by cervical spine movement and is induced by cervical spine flexion and sidelong flexion . Subjective numbness is often present in the upper member . nonsubjective sensory deficits are generally C 6 for the thumb , ascorbic acid 7 for the middle finger , and C 8 are often present in the little finger . In the presence of anterior ascendent disorder , the muscle strength of the prevailing muscle is reduced . There is diminished or wanting tendon reflexes at the disability stratum , and other tendon reflexes are normal .
Myelopathy : It is not play along by mettle root word pain and often develop with one-sided or bilateral upper limb spiritlessness . Myelopathy may grow acutely or subacutely or slowly due to dynamical injuries such as minor trauma and unfitting military posture . Neuralgia- like pain in the ass in the cervical and scapular region is often not accompanied , and even when complain of pain , it is about “ muscular tissue stiffness ” . As myelopathy progresses , spasmodic palsy of the lower limb , sensory deficits in the lower branch of the luggage compartment , and dysuria are observed .
It is address cervical spondylotic muscular wasting away , with the principal symptoms being spinal cord dysfunction and muscular impuissance in the upper limbs and muscle atrophy , with or without sensory dysfunction . In this case , specialization fromamyotrophiclateral induration becomes a problem .
How Do You Test For Cervical Spondylosis?
eminent - Level Diagnosis Of Spinal Cord Disorders : For the diagnosis of cervical spondylosis , it is important to diagnose a gamey - level upset base on the symptom of the spinal cord and/or radiculopathy and to estimate whether or not the high story in general equate the spinal electric cord compression seen on the figure of speech . is there . The cervical vertebra and cervical spinal cord have a variance of approximately 1.5 medullary segments , the C 5 medullary segment at the C 3/4 intervertebral , the C 6 medullary at the C 4/5 intervertebral , and the C 7 medullary at the C 5/6 intervertebral . Node , C 6/7 intervertebral atomic number 6 8It rough corresponds to the medullary section . The nerve ancestor run about one vertebral body downwards from the medullary section and exits the spinal canal through the foramina . For model , C 5/6 in the intervertebral high , C as spinal clause symptom 7 symptoms of appeared , the heart tooth root symptoms C 6 may appear symptomatic.(3)(4 )
Image Diagnosis : On plain cervical X - ray , it is necessary to confirm the overall alignment , narrowing of the intervertebral disc space , and the comportment or absence of developmental spinal canal stricture on a lateral aspect . If the anterior - posterior diameter of the spinal channel is 12 mm or less or the ratio of the anterior - posterior diameter of the vertebral physical structure to the spinal epithelial duct ( Torg - Pavlov ratio ) is 75 % or less at the intermediate level of the C 5 vertebral body , it is considered to be spinal canal stenosis . unstableness is measure by taking images of the prior and ulterior position in the lateral view . The oblique vista evaluate osteophytes of the Luschka joint and disc stricture due to the osteal proliferation of the facet joints .
Cervical MRI can measure the degree of spinal corduroy compression due to disc protrusion , bulgingligamentumflavum , and the presence of intramedullary hyperintensity on T 2 -weighted images .
Cerebrospinal Fluid Test : In cerebrospinal fluid , a mild to restrained increase in protein concentration is often see count on the degree of circulation upset due to densification .
Electrophysiological Examination : Electromyography show neurogenic changes in the muscles of the damaged medullary section . When a wide range of denervation findings and neurogenic changes are observe , it is necessary to consider the hypothesis of motor neuron disease . A nerve conductivity test of the upper branch is utilitarian for distinguishing it from peripheral neuropathy .
Differential Diagnosis : It is necessary to make a differential diagnosing with all disease that cause the motor and sensory shortfall in the upper limb . In peculiar , it is clinically important to spot from carpal tunnel syndrome , elbow tunnel syndrome , peripheral mettle disorders such as radial nerve paralysis , amyotrophic lateral sclerosis that first appeared in the upper limbs , and cerebrovascular disorder.(5)(6 )
