Bone protrusion at the back of the neck may be a normal bony protrusion, but it cannot be ruled out that it is caused by cervical spine protrusion, cervical spine instability, etc. Depending on the cause of the disease, physical therapy, medication and surgical treatment can be taken to promote recovery. 1. Normal bony bulge: when most people bow their heads, the seventh cervical vertebrae spinous process in the neck will be higher, and there will be obvious protrusion when touching, which is a normal physiological structure, and if there is no other abnormality, it does not need any special treatment in general. 2. Cervical spine protrusion: It is mainly caused by poor sitting, sleeping and standing postures, resulting in subluxation of the cervical joints. Early manifestation is localized bone protrusion, which can generally be treated by non-surgical methods such as traction, orthopedics and massage. If there are symptoms of localized pain, aspirin tablets, ibuprofen extended-release tablets and other drugs can be used to relieve pain as prescribed by the doctor. If the symptoms are more serious, you can have surgery. 3. Cervical spine instability: the movement of adjacent cervical vertebrae can lead to the formation of local bony elevation, which can lead to spinal nerve compression, limb weakness and even paralysis. It needs to be combined with MRI to decide the treatment. In severe cases, the cervical spine can be fixed through surgical repositioning and fusion of intervertebral implants, and rehabilitation exercises are needed after surgery to consolidate the treatment effect and improve clinical symptoms. When symptoms of convexity of the back of the neck bone appear, after physiological factors are excluded, timely consultation should be made to avoid delaying the condition.
