Bone spurs, bone degeneration, osteophytes and osteoarthritis are all common chronic joint diseases in medicine, commonly known as osteoarthropathies. Normal joints have a layer of cartilage to protect the underlying bone tissue from wear and tear, while osteoarthrosis is characterized by the constant wear and tear of the joint cartilage to the point where the underlying subchondral bone wears away and grows, resulting in bone spurs. When people reach a certain age, all organs and tissues of the body degenerate, and bone tissue is no exception. Therefore, degeneration is the basis for the development of bone spurs. In addition, congenital genetic factors, congenital abnormalities in joint structure and acquired unevenness of joint surfaces, injury or mechanical wear, poor joint alignment due to extra-articular deformities, and joint instability make the degree of bone proliferation different for each individual. What are the symptoms of osteoarthrosis? 1, from the age of onset: from the age of 40 years old slowly onset, the beginning can be due to cold, exertion or minor trauma and feel the joint soreness or dull pain, and then gradually aggravated, there may be joint friction pain. If the joints are in a certain position for too long, temporary stiffness and inflexibility may occur, and pain may be felt when changing positions. Therefore, patients often have pain in the morning when they move, and after a period of activity, they become more flexible and have less pain, but the pain can be aggravated by excessive activity. Patients often feel a creaking sound when moving the joint. If the bone spur is dislodged and forms a free body, the joint may become stuck. The interval between attacks will be shortened year by year, and finally the symptoms may be continuous. 2, from the appearance: the joint may not be swollen or mildly swollen, and some can be seen as internal and external abduction of the joint, which is called internal and external deformity in medical science. There may be pressure pain when pressing the joint by hand, and there is no restriction or partial restriction of movement. Various degrees of muscle atrophy or muscle spasm may be seen. When the knee is associated with synovitis, the swelling may increase and intra-articular fluid may develop. Some people believe that the longer the bone spur is worn, the better it gets and the less painful the joint becomes. Therefore, some elderly people start to practice climbing, walking up and down steps, walking and running for long periods of time, hoping to wear out the spurs through these exercises. As a result, instead of grinding away the bone spurs, the good cartilage and normal bones are also worn away, which aggravates the clinical symptoms and even causes bone defects, causing great problems for future joint surgery. Bone spurs are normal bone tissue, which cannot be eliminated by drugs. Clinical symptoms caused by less serious bone spurs can be solved by drugs, joint injections, physiotherapy and physical therapy, while arthritis caused by serious bone spurs can only be solved by joint cavity cleaning and artificial joint surface replacement. Artificial joint replacement is simply the removal of the worn-out layer of bone on the surface of the femur, tibia and patella at the knee joint and its replacement with a metal joint surface. The metal surfaces are separated by a polymer polyethylene cushion, just as we would normally have a brace on the outside of a tooth. The metal material used has good compatibility with human tissue and there is no rejection. To prevent or delay the occurrence of bone spurs, the following points should be noted: 1. Pay attention to maintaining an appropriate weight to reduce the pressure on the joint. 2.The necessary physical exercise, especially for the muscles around the joints, to increase the stability of the joints. 3.Try to avoid overloading the joints, avoid long distance running on hard surfaces, and avoid inappropriate climbing and stair climbing exercises to reduce the wear and tear on the joint surfaces. 4, pay attention to keep warm, especially when the seasons change. Do not let electric fans and air conditioners blow directly on joint parts in summer. When joint pain arises, go to the hospital in a timely manner and carry out treatment and exercise under the guidance of a doctor. In this way, the majority of patients with osteoarthrosis can relieve and relieve symptoms and reduce and delay the occurrence of bone spurs.
