85 percentage of grownup over the age of 60 experience cervical spondylosis.(1 )
Cervical spondylosis as the name suggests most ordinarily touch on the cervical region and in turn , the functions performed by the cervical spine are also affected . It is commonly associate with the presentation of more symptom of the upper body involving the arms , trunk , and cervix part . But it is not always as cervical spondylosis can also bear upon lower body involve legs , thighs , torso , etc.(2 )
When the changes occurring in the cervical back becomes pile up over a magnanimous period then there is cervical magnetic disk herniation and compression of the whole of the spinal cord . It denotes a chronic modification but can also pass off as an piercing instalment after there is some come down cause encountered such as heavy system of weights lifting , sudden fall from a height , snapping of the neck , etc.(2 )
Does Cervical Spondylosis Affect The Legs & Cause Leg Weakness?
The herniation of the magnetic disc causes the collapse of the distance available around thespinal cordand it is know as cervical stenosis . The spinal cord gets compressed exclusively chair to disruption of the function of the spinal corduroy . It affects the whole of the organic structure include legs and the symptoms may array from childlike leg weakness to dispatch leg paralysis . Leg impuissance orparalysiscan also occur in transverse wound syndrome and chocolate-brown Sequard syndrome(2 ) .
To understand the mechanism of involvement of leg in cervical spondylosis , it is very much important to look into the arrangement of tracts of the spinal cord . The sensorial tracts so - shout spinothalamic tract which claim the sensation of pain in the neck and temperature from the physical structure to the brain are stage at the cervical story in a personal manner in which sacral fiber are located at the outermost part and cervical fibers are place at the inmost part of the piece of ground .
When there is cervical spondylosis in its initial form then it starts by move the innermost part which precede to disruption of the function of cervical fiber and the upper eubstance gets symptom of loss of sensation . The outmost fiber of the sacral region are integral and legs are not know any symptoms . But when there is consummate stenosis of spinal infinite , outermost fibers are also affect and the patient give with deprivation of sensations in the broken eubstance .
Similar is the causa with the corticospinal tract which is responsible for transmitting the motor pulsing from the psyche to the muscles . The musical arrangement of the corticospinal tract at the cervical stage is alike to that of the spinothalamic tract but are located anteriorly . It causes the symptoms of weakness of the muscles of the upper body in its initial demonstration and by and by on it can involve the lower body as well then there is the symptom of leg impuissance and leg paralysis(3 ) .
vesica / gut participation can also be take care at such a late phase off the condition leading to incontinence of urine and feces . ulterior column fibers have an opposite arrangement to that of sensory and motor tract arrangement but are site posteriorly in the spinal cord and get involve at the last . So , its intimacy in the upper and lower consistency can pose at the same time .
Conclusion
It is very much possible that the patient of cervical spondylosis can award with the symptoms of leg weakness and leg paralysis . It can be one-sided or bilateral calculate upon the extent of engagement of the spinal corduroy . But it commonly is seen either in the acute installment when there is a sudden collapse of the cervical vertebrae under some injury chemical mechanism or it hap in the ulterior stages of a continuing case of cervical spondylosis . It can also lead to the participation of the autonomic system which controls the sphincters like that of bladder or bowel award with the ill of incontinence . The respectable part about the cervical spondylosis is that it has a very slow progress and can be kept in control with adequate quantity .
