Cervical 3 vertebral body instability usually does not require special treatment if the condition is mild and only requires good lifestyle habits. If the patient’s condition is more serious, it can be treated by manipulation, immobilization and surgery. Cervical 3 vertebral instability may be caused by asymmetry of the upper and lower articular spaces on both sides and unnatural physiological curvature. If the symptoms of cervical vertebral instability are mild and not accompanied by other symptoms, special treatment is usually not required. The patient only needs to avoid working with the head down for a long time, playing with the cell phone and other bad habits, and then it can be slowly healed. If the patient’s cervical 3 vertebrae instability is more serious, manipulation can be used to correct the misalignment of the joints, or a neck brace can be worn to immobilize the patient. If the patient is also suffering from urinary and fecal incontinence, surgery is needed. Patients with cervical 3 vertebral instability need to seek medical attention in a timely manner. If the condition is mild, it is sufficient to change lifestyle habits. If the condition is severe, treatment should be carried out under the guidance of a doctor.
