Hand numbness caused by cervical spondylosis is mainly caused by nerve compression due to degenerative changes and osteophytes in the cervical spine, and is commonly seen in neurogenic cervical spondylosis, sympathetic cervical spondylosis and mixed cervical spondylosis. Neurogenic cervical spondylosis is mainly caused by degenerative changes and osteophytes of the cervical spine causing compression of the brachial plexus nerve and causing corresponding symptoms, most commonly numbness and pain of the upper limbs, and the pressure neck test or brachial plexus pull test is mostly positive. Sympathetic cervical spondylosis is a kind of cervical spondylosis with complex clinical symptoms, mainly caused by stimulation of the vegetative nerves. It can have symptoms of hand numbness, but mostly manifests as a series of sympathetic symptoms such as dizziness, blurred vision, tinnitus, elevated blood pressure, tachycardia and anterior heart pain. If a patient has a combination of both neurogenic cervical spondylosis and sympathetic cervical spondylosis, that is, mixed cervical spondylosis, symptoms of hand numbness can also occur. Clinically, it should also be distinguished from other diseases that can cause hand numbness, such as thoracic outlet syndrome and carpal tunnel syndrome. For hand numbness caused by cervical spondylosis, it is necessary to seek active treatment from a professional rehabilitation or massage doctor or orthopedic surgeon.
