Due to changes in lifestyle and office style, the number of patients suffering from various types of cervical and lumbar spondylosis is increasing today, and the trend of youth is becoming more and more obvious. Cervical and lumbar spondylosis has turned from a geriatric disease in the past into a common disease for middle-aged and young people and an “occupational disease” for white-collar workers in offices today, and even some teenagers have joined the ranks of cervical and lumbar spondylosis patients. Although the symptoms of cervical spondylosis and lumbar spondylosis are not identical, their pathogenesis has similarities. As people age and the spine is in an incorrect posture for a long time leading to strain, sometimes combined with spinal trauma, degenerative disc protrusion, vertebral body posterior edge and small joint protrusion to form bone superfluous (commonly known as bone spurs), yellow ligament hypertrophy, etc., the spinal cord, nerve roots, sympathetic nerve and vertebral artery compression, and then a series of clinical syndromes. Cervical spondylosis is the most serious Cervical spondylosis can be divided into several types according to the symptoms and the tissues involved in the lesion, among which spondylotic cervical spondylosis is the most serious. The main manifestations of spinal cord cervical spondylosis are weakness and numbness of the limbs, especially inflexibility of the upper limbs, impairment of the fine activities of the hands, weakness of holding things, easy to fall, difficulty in tying buttons and choosing vegetables, unstable walking, easy to fall or walking difficulties, the feeling of stepping on cotton in the feet, and in severe cases, urinary and fecal dysfunction, and even bedridden so that life cannot be taken care of. In addition to symptoms and physical examination by a doctor, the diagnosis of cervical spondylosis usually requires some imaging examinations, including X-ray, CT or MRI of the cervical spine. These tests can detect bone formation, spinal cord compression, narrowing of the spinal canal, and identify and rule out other diseases. Cervical spondylosis should be treated as soon as it is detected. Many cases have shown that non-surgical treatment can be tried for certain mild cervical spondylosis, especially vertebral artery and sympathetic cervical spondylosis, but once spinal cord cervical spondylosis is diagnosed, most of them require surgery. For cases of anterior spinal cord compression, anterior decompression and internal fixation can be done; for multiple segmental compression or combined with posterior longitudinal ligament calcification, posterior cervical spinal canal enlargement and shaping can be applied. Clinically, it is found that some spinal cord cervical spondylosis only manifests as finger numbness or grip strength loss in the early stage. Early diagnosis and treatment of such patients can prevent or reduce the further development of spinal cord lesions, but conversely, there is a risk of aggravation of the disease. Surgical methods for lumbar spondylosis should be carefully selected Degenerative lesions of the lumbar spine include bulging and herniated discs, hyperplasia, lumbar instability, spinal stenosis, etc., resulting in symptoms such as back pain, leg pain, numbness of the lower limbs and difficulty walking. For these degenerative lesions of the lumbar spine, surgical treatment is required when conservative treatment is ineffective. Traditional surgical methods include decompression to relieve nerve compression, screw internal fixation and fusion surgery. The purpose and principle of surgery is to remove the disc, decompress the nerve, and restore stability and motion of the lumbar spine while protecting the normal lumbar weight-bearing and motion and nerve function as much as possible. Usually, the results of the procedure are satisfactory, especially when operated under discoscopy with less trauma, less bleeding and faster recovery. In patients with spinal stenosis, the usual decompression and internal fixation procedures are more invasive and require fusion to fix part of the lumbar spine resulting in loss of motor function and even causing new lesions in adjacent areas due to excessive pressure, leading to recurrence of back and leg pain and nerve compression. In order to solve these problems, in recent years, spine surgeons around the world have been dedicated to exploring and researching new surgical techniques, among which artificial disc replacement and dynamic spinal fixation techniques have been born, bringing a blessing to the majority of patients with back problems. Artificial disc replacement is an artificial device that mimics the function of the disc. The surgery not only removes the diseased disc, but also restores the stability and mobility of the segment, theoretically avoiding the accelerated degeneration of the adjacent segment caused by lumbar spine fusion. The Wallis Interspinous Dynamic Stabilization System is a type of dynamic spinal fixation technique. It allows for dynamic fixation while relieving nerve compression, restoring stability of the lumbar spine while preserving the motion function of the lumbar spine at the surgical site. Each surgical method has its own indications and contraindications. You should follow the advice of a professional spine surgeon based on full communication with your doctor as to which surgical method is right for you.
