Adult congenital dislocation of the hip

Introduction to adult congenital dislocation of the hip Adult congenital dislocation of the hip, also known as adult acetabular dysplasia, is a congenital dysplasia, one of the common causes of hip pain, and an important cause of hip osteoarthritis. It is generally believed that the incidence of this disease is higher in women than in men, with a male to female ratio of approximately 1:5, and a family history in one in four patients. Genetic factors have been noted in the study; acetabular dysplasia and joint ligament relaxation; and fetal fetal abnormalities in the uterus, suffering from abnormal mechanical stress, affecting the development of the hip joint, etc. caused congenital dislocation of the hip. There is also a big reason that women often wear their bodies during their children. If a pregnant woman often bends over, the child after birth is prone to congenital dislocation of the hip. For example, women during pregnancy often sit and wash clothes; bend over to take things and so on. Especially for pregnant women who are buying and selling, they often bend over and get the goods, which is easy to cause the birth of children to be congenital dislocation of the hip. basic knowledge Sickness ratio: 0.1% Susceptible people: more often in adults Mode of infection: non-infectious Complications: bone hyperplasia

Causes of congenital dislocation of the hip in adults

Cause:

The cause of the disease is still not fully understood. Genetic factors have been noted in the study; acetabular dysplasia and joint ligament relaxation; and fetal fetal abnormalities in the uterus, suffering from abnormal mechanical stress, affecting the development of the hip joint, etc. caused congenital dislocation of the hip. There is also a big reason that women often wear their bodies during their children. If a pregnant woman often bends over, the child after birth is prone to congenital dislocation of the hip.

Adult congenital dislocation of the hip

The disease is caused by traumatic factors, attention to production and safety, to avoid injury is the key to prevent this disease. Another need to pay attention to hip dislocation should be promptly diagnosed and treated, because there are a few dislocations combined with acetabular fractures must have X-ray film to confirm early re-adjustment The effect is also better. Most of the old patients have relatively poor surgical re-effects. In addition, improper treatment can cause avascular necrosis of the femoral head to seriously affect joint function.

Adult congenital dislocation of the hip Complications

With severe acute osteoarthritis, most of the articular cartilage has been destroyed, bone hyperplasia of the acetabulum and femoral head, narrow or even disappeared joint space.

Adult congenital dislocation of the hip Symptoms Common symptoms Rheumatoid arthritis Hip pain Hip dislocation

Most adults with acetabular dysplasia develop symptoms between the ages of 25 and 40. Early manifestations of hip fatigue, soreness, and dull pain can occur in the thigh roots or in front of the thighs or hips. When the disease progresses, the joint pain is aggravated, and there is pain in the leg and the rest. As the femoral head shifts outward and upward, the affected limb becomes shorter. As osteoarthritis worsens, joint activity is gradually affected.

Adult congenital dislocation of the hip

In the pelvic orthotopic X-ray film, the acetabular dysplasia is mainly characterized by small or shallow acetabular development, the negative focus of the femoral head is shifted outward, the medial space of the hip joint is widened, and osteoarthritis is secondary. Doctors can take a variety of professional methods to measure the relative position between the acetabulum and the femoral head to make a final diagnosis of the disease.

Diagnosis and diagnosis of congenital dislocation of the hip in adults

1. Diagnosis of posterior dislocation of the hip joint

From the clinical manifestations of patients, there is a high degree of suspicion of the presence of posterior dislocation of the hip. X-ray examination should be performed. Usually, the hip joint can be diagnosed, showing the femoral head in the posterior or posterior aspect of the acetabulum, and the inner edge of the femoral neck. The middle section of the continuous arc of the upper edge of the closed hole. If the combined damage exists, a corresponding image examination should be performed. CT scan is important for the diagnosis of femoral head fractures, acetabular fractures or the presence of osteochondral fragments in the joints.

2, the diagnosis of anterior dislocation of the hip

When the orthotopic X-ray film cannot be determined to be the anterior superior dislocation or the posterior superior dislocation, the lateral X-ray of the hip joint can be taken: the upper end of the anterior superior dislocation has an external rotation position (ie, the rotor becomes larger, the femoral head becomes rounded, and the intertrochanter shows clearly), the large rotor moves inward. The upper end of the posterior superior dislocation femur usually has an internal rotation position, the small rotor becomes smaller or disappears, the inter-rotor ridge is unclear, and the large trochanter moves outward. In addition, the anterior superior dislocation femoral shaft has no adduction, and the posterior superior dislocation femoral shaft is often in the adduct state. Sometimes due to factors such as the patient's position or projection, there will be a positive X-ray film showing that the corresponding relationship between the femoral head and the acetabulum is normal. At this time, the lateral position film is obviously improved to correct the diagnosis. When complicated with acetabular or femoral head fractures, CT examination can determine the location of the acetabular and femoral head fractures, the size of the fracture piece and the presence of broken bones in the joint cavity, which has a positive effect on further treatment of the patient.
