As the saying goes, “people’s legs get old before they get old”, and this was fulfilled in the case of Mr. Zhang, a 60-year-old teacher who retired from work and did not suffer any trauma, suddenly found that he had a stiffness in his right hip after a long period of immobility, which became “bright” after exercise, but After walking for a long time, he had pain in his right hip and could not take a step with his heavy right leg, which could be relieved after a short rest, but if he continued to walk, the above symptoms would recur. At that time, Ms. Zhang did not take this to heart, but after a long time, she felt that her legs were not equal in length and her right leg was a bit “stubby” when she walked, so she went to the joint surgery clinic for an examination and found that she was suffering from “right hip osteoarthritis”. After the artificial joint replacement surgery, Ms. Zhang’s right leg does not hurt anymore, and she does not “stub her toe” when walking, even when dancing with her sisters, outsiders cannot tell that she has a prosthetic joint. Osteoarthritis of the hip joint is a chronic hip joint disease, also known as hyperplastic arthritis or hypertrophic arthritis. It is characterized by the degeneration of hip cartilage and the formation of new bone under the cartilage and around the joint, and is one of the common orthopedic disorders. Obesity, joint injury, and joint overuse can all contribute to the development of osteoarthritis. Therefore, obese people, athletes, and people who use a joint mechanically and repeatedly for a long time (such as typists, IT workers, porters, textile workers, teachers, salesmen, etc.) are at a high risk of osteoarthritis. Primary osteoarthritis of the hip joint occurs in people after the age of 50; secondary osteoarthritis predisposes people to a younger average age, usually around 40 years old, mostly secondary to congenital acetabular dysplasia, femoral head necrosis, fracture dislocation or after inflammation. The main symptoms are pain, claudication and functional limitation, with pain often radiating to the medial aspect of the knee. The affected joint often has joint gluing, which means that after a long period of immobilization in a certain position, the joint is difficult and painful to move at first, and the gluing disappears after a short period of activity. If your joint shows the above symptoms, you should consider the possibility of osteoarthritis and see your doctor as soon as possible for timely diagnosis and treatment. Primary osteoarthritis of the hip develops slowly, while secondary osteoarthritis of the hip develops more rapidly than the former. The disease is generally treated with “three-dimensional holistic dynamic balancing therapy” for hip osteoarthritis; proper rest, reducing weight bearing and joint burden; elimination of causative factors; physical therapy and appropriate activities and exercises; and western medicine for non-steroidal analgesics. If conservative treatment is not effective, artificial total hip joint replacement surgery can be performed. Total hip arthroplasty has become one of the most successful and reliable surgical procedures in the field of orthopedics, which means that the diseased component of the hip joint is surgically removed and replaced with a new artificial component – what we call an artificial prosthesis (according to the composition of the hip joint, there are acetabular and femoral prostheses). to improve the function of the hip joint at the same time.
