Experts explain the prevention and treatment of acetabular dysplasia Young women’s joint swelling, pain: be careful of another “ambush” behind if the usual posture of the “shoppers” suddenly and continuously appear knee or hip swelling, most people may not think that this seemingly simple joint sprain may be behind another hidden problem. Most people may not think that there may be a hidden agenda behind this seemingly simple joint sprain. “The early onset of acetabular dysplasia is often characterized by soreness in the knee joint, a symptom that often “fools” patients, causing many to let their guard down and delay This “sound and fury” symptom often “fools” patients, causing many to let down their guard and delay treatment. Dr. Chen Xiaodong, director of the Department of Adult Orthopedics at Xinhua Hospital of Shanghai Jiao Tong University Medical College, will explain the symptoms and prevention tips of acetabular dysplasia. The “street shopper” is caught in a joint pain mystery Xiao Wang, who loves shopping, recently had to give up his hobby of shopping and recuperate at home to “fight” knee pain. He was puzzled when he went to the hospital for a knee examination and found that everything was normal. At this time, she began to experience increasing pain in her groin area. After an accidental follow-up X-ray, Wang was diagnosed with “acetabular dysplasia”, which was the “culprit” for the constant pain for days. She was puzzled as to why she had developed hip dysplasia as an adult. Why is this disease in more than 20 years without pain symptoms? In fact, in daily life and Wang have the same experience of young women are not a few, they are in the mystery of joint swelling, pain because of acetabular dysplasia in the “play”. Acetabular dysplasia, also known as hip subluxation, is a hip deformity formed by the failure of the acetabulum to develop well. The main pathological change is the shallow acetabulum, resulting in insufficient acetabular inclusion and coverage of the femoral head. As a result of these pathological changes, the weight-bearing area of the hip joint is reduced and the pressure per unit area is significantly increased, which gradually causes damage and degeneration of the articular cartilage and eventually leads to osteoarthritis of the hip joint, resulting in hip pain and limited movement. As a result, acetabular dysplasia has a high disability rate. The initial symptoms “prefer” to be “heard” The painful manifestations of acetabular dysplasia are often “heard” in the early stages, causing the typical “sore knee”. This is one of the main reasons why acetabular dysplasia is often neglected and missed. Experts explain this by saying that hip lesions are not necessarily reflected in the hip at the earliest. Instead, the lesion tends to irritate the nerves and radiates to the knee joint, causing pain or discomfort in the knee area. Because of this, patients often mistakenly think that something is wrong with the knee in the early stages, but after a knee examination, the results often show that everything is normal. If patients can understand the symptom of “acetabular dysplasia” and pay attention to the “ambush” behind the knee pain, they can If you think about getting an X-ray of the hip joint, you will be able to identify the problem early. Unfortunately, most people are not aware of this. It is also important to note that pain in the hip joint itself often means that serious damage to the hip cartilage has occurred. Generally speaking, the severity of hip pain is related to the degree and extent of damage to the articular cartilage. As the disease progresses, the joint pain increases and the range of motion of the hip joint is easily affected. At this time, patients often have to use crutches to walk, which seriously affects the quality of life. Young women are easy targets for orthopedic diseases such as back pain, which are most likely to target women, and acetabular dysplasia is no exception. Women, especially young women, often become the “main” target group of acetabular dysplasia. Epidemiological studies have shown that the incidence of acetabular dysplasia is about 0.6%, with a male to female ratio of 1:6, especially in women. In general, most patients develop symptoms around the age of 20 to 40. Since the hip joint is only semi-dislocated during the onset of the disease, but not fully dislocated, the patient does not produce any symptoms during childhood and adolescence and walks like a normal person. However, the younger the patient is when the painful symptoms appear, the more severe the degree of acetabular dysplasia and the worse the prognosis. In addition, unlike common back pain, the soreness caused by acetabular dysplasia is initially located in the knee joint and later mainly in the hip, the root of the thigh, and the groin area. Initially, the pain and discomfort in the hip area will be aggravated after prolonged standing or walking, and will generally improve after rest. Most patients think it is due to strain or sprain, and do not pay attention to it. Therefore, if the hip joint is sore, swollen, painful, accompanied by or alone with knee pain, it is necessary to go to the hospital in time for a targeted examination. It is important not only to observe whether the knee joint is abnormal, but also to take an X-ray of the hip joint in order to detect the hip joint lesion in time. Generally speaking, the joint space may appear normal on X-rays because the damage to the articular cartilage is mild at the beginning of the disease. However, with the further aggravation of the hip cartilage damage, the joint space may become narrow or even disappear, and even bone spurs may be formed, which may eventually lead to osteoarthritis. If you do not pay enough attention to the hip pain and discomfort at the early stage, but go to the hospital for examination only after the hip pain or even limp occurs, you may have missed the best time for treatment. The three orthodontic methods are “typed”. For patients with early acetabular dysplasia, early detection and early surgical correction of the hip deformity can effectively relieve or even eliminate hip pain. Since the root cause of joint pain is due to joint deformity, orthopedic surgery can generally preserve joint function, stop or delay the onset and progression of osteoarthritis, and eliminate or delay the need for artificial joint replacement surgery. Currently, a variety of osteotomies and orthopedic procedures are available for early treatment in children and adolescents. In adults, a periacetabular osteotomy is recognized worldwide as an effective method. This procedure corrects the acetabular deformity through osteotomy and restores the correspondence between the acetabulum and the femoral head to near normal, thereby eliminating joint pain. For young patients with acetabular dysplasia, this is the best procedure for treating acetabular dysplasia. For patients who have lost the best time for early treatment, their condition has progressed to an advanced stage, forming osteoarthritis and significantly limiting joint movement. In this case, joint fusion fixation can be considered, which means that a painful, but still movable joint is turned into an immobile, but painless joint. However, although joint fusion surgery can be a good solution to hip pain, it leaves the joint stiff and immobile, which can easily bring many inconveniences to the patient’s future life. In addition, with the extension of time, patients may also gradually develop lesions in the lumbar spine as well as the knee joint, causing pain in the aforementioned areas. Therefore, many young patients have doubts about this procedure. A third, more effective treatment option is joint replacement surgery. Hip replacement is a good surgical option for patients with advanced osteoarthritis, as it not only provides effective pain relief, but also allows for a mobile hip joint. However, it is important for patients to note that any artificial joint has a certain lifespan. This means that within a decade or two after the joint is replaced, a second artificial joint revision surgery may be necessary. Not only do you have to suffer a second time, but it is also expensive. Therefore, it is important to take good care of the artificial joint.
