Many patients with hand numbness and hand pain are the root cause of cervical spondylosis, it is worth noting that the numbness of the fingers caused by cervical spondylosis has certain characteristics, either manifested as the radial side (thumb, index finger or combined middle finger) numbness, or manifested as the ulnar side (pinky, ring finger or combined middle finger) numbness, or 5 fingers numbness, sometimes not only numbness of the fingertips, sensory dullness, but also can involve the forearm, upper arm, serious cases can also be accompanied by In severe cases, there may be a loss of grip strength. The degenerative herniated cervical disc can cause irritation, strain or compression of the spinal nerve roots, resulting in reactive edema of the spinal nerve roots and surrounding tissues, spinal stenosis and possible adhesions at the vertebral cuff, resulting in numbness of the fingers. These pathological changes interact with each other and can result in a prolonged and recurrent course of the disease. When different vertebral segments are involved, different spinal nerve roots can be stimulated accordingly, producing numbness in different areas. When the sixth spinal nerve root is involved, the radial side of the forearm and the thumb often become numb; when the seventh spinal nerve root is involved, the index finger and middle finger may become numb; when the eighth spinal nerve root is involved, the ring finger and little finger may become numb; if the sixth and eighth spinal nerve roots are also involved, all five fingers may become numb. In patients with neurogenic cervical spondylosis, numbness in the fingers combined with decreased grip strength may coexist. However, symptoms of sensory impairment (e.g., numbness) manifest earlier because of the higher sensitivity of sensory nerve fibers. In addition to the clinical manifestations of finger numbness and grip strength loss, neurogenic cervical spondylosis may also include symptoms and signs such as radiating pain in the upper extremity, altered skin perception in the upper extremity, a positive brachial plexus pull test, weakened or absent tendon reflexes, and atrophy of the interosseous muscle or bone question muscle. The incidence of neurogenic cervical spondylosis is relatively high, accounting for more than 60% of the total number of cervical spondylosis of all types. This is mainly due to the relatively large amplitude and high frequency of activities in the lower cervical spine. This type of cervical spondylosis can be seen in all age groups, and there is no significant difference between genders. The numbness of the fingers may recur due to trauma, excessive neck activity, poor lying posture and other triggers, and gradually worsen with the course of the disease. Treatment of cervical spondylosis 1.Conservative treatment: There are many conservative treatment methods for cervical spondylosis, such as acupuncture, massage, massage, physical therapy, traction, exercise, etc. Conservative treatment of cervical spondylosis can only play a temporary role in relieving symptoms, and cannot cure the disease, because conservative treatment is treatment of the appearance, rather than treatment of the cause, so it is easy to relapse. 2.Conventional surgery: Conventional surgery for cervical spondylosis can be completely cured, but the surgery is traumatic and the recovery time after surgery is longer. It is often used for spinal cord compression of more than 3 degrees, degenerative disc herniation of multiple segments and acute injury caused by trauma. 3.Minimally invasive technology for cervical spondylosis: it is a new treatment method between conservative treatment and surgical treatment, which is more effective than conservative treatment and safer and more reliable than surgical treatment. The technology uses imaging positioning technology under local anesthesia to treat precisely to the lesion site, which can quickly relieve the pain caused by tissue pressure and has the characteristics of good effect, small trauma, fast recovery and less complications.
