1.Why is there a posterior lumbar joint disorder? Posterior lumbar joint disorder refers to a series of clinical manifestations caused by abnormal changes in the position of the lumbar spine synovial joint relationship. It is also called lumbar small joint dislocation, lumbar posterior joint subluxation, and joint synapse syndrome, and it occurs in young and middle-aged people. The posterior lumbar joint is a micro-movement joint. Its joint surface is mostly in sagittal position except for the coronal position between the fifth lumbar vertebra and the first sacral vertebra. The outer layer of the joint capsule is the fibrous layer and the inner layer is the synovial layer. The synovial layer is rich in sensory and motor nerve fibers and is extremely sensitive to stimulation and inflammation. The posterior joint capsule is innervated by the articular branch from the medial branch of the posterior spinal nerve. The above anatomical features determine the greatest relative displacement of the posterior lumbar joints when the spine is excessively flexed forward. If the position is changed, the body is suddenly turned, and the bending work is performed for too long, the joint surface of the synovial joint is subjected to uneven forces, which can easily lead to dislocation or subluxation, thus affecting the function of the joint and involving the nerve (joint branch and nerve root out of the corresponding intervertebral foramen). The spine of the middle-aged and elderly has a period of instability, and it is easy to cause posterior joint disorders due to small-scale activities. 2.What are the types of posterior joint disorders of the lumbar spine? Most patients have subluxation of the posterior joints, causing painful strain on the corresponding joint capsule. In some patients, because of excessive forward flexion of the spine, synovial impingement occurs when the back is straightened, causing severe pain. 3.How is posterior lumbar joint disorder treated? Tui na treatment is a very effective treatment. Acupuncture will also have an immediate effect. Local seal or pain medication can also be used for those with severe pain. 4.Why can tui na treat posterior lumbar joint disorder? The posterior lumbar joint disorder is mainly due to the abnormal position of the joint protrusion. The massage treatment first uses rolling, kneading and plucking methods to relax the muscles appropriately, and then adopts the oblique wrenching method, seated rotational reset method, back method or short lever fine-tuning technique to correct the joint position, which can immediately relieve the patient’s pain. 5.What are the advantages of massage for posterior lumbar joint disorder? Most importantly, it is fast. 6.What should people with posterior lumbar spine joint disorder pay attention to? Bed rest and warmth are recommended within three days after correction. For the posterior edge of the lumbar vertebral body and posterior joint hyperplasia should be used with caution or prohibited sitting rotation reset trigger method. 7.How to prevent posterior lumbar joint disorder? Pay attention to the posture in work and daily life, and do not change position too quickly; carry out appropriate preparatory activities before lifting heavy objects, so that the lumbar muscles can gradually adapt.
