Traction is an effective way to treat cervical spondylosis, but there are many little-known details about traction, which not only determine the indications for traction, but also have a direct relationship with the efficacy of traction. 1, traction posture: traction posture and traction habits and directions are related, whether it is sitting traction or lying traction for general cervical spondylosis is no difference, only some special patients can only take a fixed position traction. 2, the angle and direction of traction: traction in addition to traction to the side of the head, there are some special requirements, that is, some specific details of the problem, traction is divided into neutral traction, flexion traction, posterior extension traction, and micro-extension or micro-flexion traction, in addition to the head to the left or right traction. General hospital traction is a fixed posture traction, traction is not to say the direction; more advanced hospitals use different vertebral spaces with different traction direction, but all fixed traction, generally favor traction upper vertebral body with a certain angle traction, traction lower vertebral body with a certain angle traction in favor of flexion, the middle vertebral lesions mostly use neutral traction; we require the However, the specific traction direction is based on a clear localization of the lesion gap and the specific situation of the gap lesion, which is based on the patient’s physical signs, physical examination, MRI examination and the specific situation of the dynamic X-ray. The direction of traction can be opposite if the lesion gap is the same. 3, the weight of traction: traction weight and traction posture, position and time have a great relationship, the general traction weight in 3 – 8KG. 4, traction time: traction time and the nature of the disease, traction weight and position have a greater relationship, the weight of the traction time will be reduced. General sitting traction time will be lower than the lying traction time, conventional traction time in 10 – 30 minutes. 5, the frequency of traction: the frequency of traction and traction weight, time and the nature of the disease is related. Short time and light weight traction can be carried out several times a day. 6, the purpose and role of traction: the purpose and role of traction is to maintain the posture of the head and neck, expand the gap distance (limited role), with the help of ligaments and muscles to correct the small displacement, instability and rotation between the vertebral bodies. 7, the indications of traction: adapted to acute attacks of various types of cervical spondylosis, for sympathetic and vertebral artery type effect is particularly significant (in the past, because of incorrect traction direction, some patients symptoms aggravated some scholars do not recommend traction), but the direction and angle of traction is particularly important. 8, traction of contraindications: progressive symptoms of the more severe spinal cord type cervical spondylosis is generally not recommended traction; other diseases (maxillofacial, cranial, cardiovascular, respiratory, etc.) can not adapt to traction. 9, the side effects of traction: incorrect traction direction will aggravate the patient’s condition, excessive traction weight and time will cause new injuries. Although the cervical traction seems simple, but the learning is very deep to learn a lot, and the efficacy and indications have a great relevance, incorrect direction will not only reduce the patient, but also aggravate the symptoms, please choose carefully.
