Lumbar small joint disorder syndrome is also known as small joint synovial imbrication. Mostly due to mild acute lumbar sprain or bending and jerking up, the synovial membrane is embedded between the small joints, causing interlocking or dislocation of the small joints and limiting the movement of the spine. Immediately after the injury, an unusual and severe pain occurs, making it unbearable for the patient. Patients often lie on their sides in flexion, with emotional tension and muscle tension, afraid to move for fear of being touched or moved by others, and any movement of the spine, coughing, or vibration will make the pain worse. Due to the pain, the lumbar muscles are in protective muscle spasm, and the lumbar vertebrae become flat or slightly posteriorly convex or slightly laterally convex. Swelling of the upper end of the synovial membrane can irritate the nerve roots located in the intervertebral foramina, producing radiating pain that is aggravated by hyperextension and is less irritating and less painful when the synovial membrane is stretched during bending. However, the disease is mainly characterized by low back pain, and nerve root irritation symptoms appear less frequently. Treatment: The main treatment for lumbar small joint disorder syndrome in the acute stage is bed rest, while oral pain relievers and antispasmodics such as Valium and Shujin Ling can relieve and eliminate lumbar muscle spasm and reduce the pressure on the intervertebral joints, which is very effective in promoting the withdrawal of the embedded synovium. In addition, we can also try: traction: patient prone position, abdominal pillow, the operator holds the ankle slowly traction up to 1min, and then slowly release, 1min and then repeat traction, after several times, bed rest. Acupuncture: take Kidney Yu, Waist Yang Guan, Zhi Mou, Qi Hai Yu and A-Yi points, etc. After acupuncture, fire cupping can be used. Physiotherapy: electrical excitation stimulation can be used in the acute stage to relax the muscles, and the rest of the ultrashort wave and microwave therapy should be used in the recovery period or when chronic pain is present. Small joint capsule closure: the acute period can be analgesic and antispasmodic, and the chronic period can be analgesic and anti-inflammatory, which is beneficial to the recovery of the disease. Manual therapy: Manipulation can resolve synovial impaction and restore the joint position to normal, which has the effect of relieving spasm and relieving pain. Treatment method: The patient lies prone on a hard bed, and the doctor touches the spinous process from top to bottom with the thumbs of both hands to find out the pressure and pain points. Careful touching will reveal that the spine is not in the same line with other spines, and the spine tends to deviate to one side. After finding the lesioned spinous process, first relax the local muscles of the lesion, paying attention to avoiding the lesioned area, usually by kneading, pushing and stroking, usually for 5-10 min. after the muscles are relaxed, ask the patient to lie on his or her side (if the next spinous process is skewed to the left, ask the patient to lie on his or her right side; if the next spinous process is skewed to the right, ask the patient to lie on his or her left side), with the patient’s chest side as close to the bedside as possible and the doctor standing on the patient’s The patient’s thoracic side is as close to the bedside as possible, the doctor is standing on the patient’s front side, make the patient’s upper body rotate backward as much as possible, the lower body rotate forward as much as possible, the upper leg is placed on the side of the diseased spinous process with knee and hip flexion, both elbows push the shoulder and hip slowly at the same time, make the patient’s waist rotate to the maximum, then both elbows suddenly push, and push the spinous process with the thumb placed on the spinous process at the same time, when a “thump” sound is heard, it proves that there is At this time, the patient was asked to get out of bed slowly and do activities in all directions of the lumbar region slowly, and could move freely, but felt slight pain in the lumbar region, but it was significantly better than before. The patient was asked to go home and rest on a hard bed for 7-10 days, and then he could participate in work normally. For patients with long duration of illness and strong body, if the reset is unsuccessful, horizontal traction of the lumbar spine for 10 min can be used first, and then reset by the method above, which is mostly successful.
