Cervical ankylosis is a common condition of ankylosing spondylitis, and its head and neck movement is limited by inflammatory ankylosis of the vertebral body axial joints and tendon ligament bone attachment points in addition to the distal attachment points that we have found clinically to be a cause of symptoms. For example, the relationship between limited cervical movement and damage to the oblique angle muscles of the neck is very obvious. According to the data, at present, needle knife in the treatment of cervical ankylosis is usually performed to release the soft tissues between the transverse and spinal processes, as well as to release the starting point of the oblique angle muscle. Because of the abnormal abundance of neurovascularity in the stopping point of the oblique angle muscle, acupuncture or acupuncture here is quite dangerous, so the release of its stopping point has not been reported until now. We have five cases of cervical ankylosis with severe pain at the stop point of the oblique angle muscle in the clinic and the relaxation at its starting point was ineffective, and the treatment of its stop point received better results instead. The anatomy of the oblique muscle is as follows: The anterior oblique muscle starts from the anterior node of the transverse process of the cervical vertebrae 4-6 and ends at the node of the anterior oblique muscle of the first rib. The middle oblique muscle starts at the posterior node of the transverse process of cervical 2-7 cervical vertebrae and ends at the posterior aspect of the subclavian artery sulcus of the first rib and the intercostal epicranium of the first intercostal space. The anterior medial aspect of the anterior oblique muscle is the longitudinal structure between the cervical region and the roof of the pleura, and its anterior, posterior, and external measurements are the transverse vessels and nerves between the thorax, neck, and upper extremity (the anterior oblique muscle is preceded by the passage of the subclavian vein, and the subclavian artery and brachial plexus nerve between the anterior and middle oblique muscles and the first rib). The role of the oblique muscles: lift the two teams of ribs, one side of the oblique muscle contraction, can make the spine neck to the same side of the tilt, both sides of the oblique muscle contraction at the same time, the neck forward curvature. Indications: 1, cervical ankylosis with painful tension in the neck muscles. 2, pain in the supraclavicular fossa with obvious pressure points in the first rib. 3, pain relief is not obvious after the release of the oblique angle muscle initiation point. Treatment: 1. Position: The patient is seated with both arms naturally hanging down. Remove the upper garment and completely expose the site of surgery. 2.Positioning: mark the painful point as described by the patient and determine the site of the first rib. Local sterilization is routine. 3.Inject the needle knife: the surgeon presses the pain point with the left thumb gradually and pushes it back and forth to the first rib surface to separate the subcutaneous vascular nerves to the side of the thumb. Make sure there is no arterial pulsation under the finger and that the patient has no nerve compression such as numbness in the upper extremity. The needle knife is pressed against the nail surface of the thumb, and the incision is parallel to the patient’s coronal surface, gently stabbed into the subcutaneous and gradually stabbed into the subcutaneous tissue up to the bone surface of the first rib, after reaching the bone surface, hold the needle knife and slowly relax the left thumb so that the soft tissues such as the skin at the site of the operation recover to spring up and recover, and the needle knife is pressed against the bone surface, and 3-5 incisions are made along the rib surface at the most sore and swollen area. Press the incision to exit the knife. And press for 3 minutes to make sure there is no subcutaneous bleeding and then cover the wound with a band-aid. 4.Manipulation: The doctor’s left hand presses the incision, and the right hand pushes the patient’s head and neck to the opposite and posterior side in order to pull the oblique muscles and make them completely relaxed, after the operation, it is necessary to make sure that the patient’s wound is not bleeding again before finishing. The treatment of the opposite side is the same as before, but the other side can be treated only after one side is completely done. Summary: 1. According to the function of the oblique muscle, we know that the backward tilt and turn of the head has a considerable connection with it, while patients with cervical ankylosis mostly show the head fixed in a forward bending position, can not be tilted up and side-bending or turning, and in severe cases can only see the ground in front of their toes, can not raise their heads to look flat, in addition to the soft tissue inflammation around the cervical spine In addition to the inflammation of the soft tissues around the cervical spine, the lesion of the oblique angle muscle is also an important factor. 2, those who have cervical ankylosis without pressure pain in the first rib of the supraclavicular fossa should not do the release of the oblique angle muscle. 3, supraclavicular fossa because of the anatomical structure is very complex and important, needle knife treatment has considerable risk, the operation should be very careful, not familiar with anatomy and needle knife operation should not use this method. 4, after the needle knife technique is very critical, the first of the five cases did not do the oblique angle muscle pulling technique, the patient’s postoperative relief feeling is obviously not as good as the last four cases to do the technique. 5, due to the current accumulation of too few cases, the number of occipital wall distance statistics appear to be not very meaningful, to be improved in the future.
