What Are the Symptoms of a Hip Replacement Dislocation?

The dislocation of the center of the hip joint, the acetabulum and the femoral head, which form the hip joint, are closely matched in form. It is a typical club and mortar joint with strong ligaments and strong muscle groups around it. Therefore, only strong violence can cause the hip Dislocation of joints.

Dislocation of the center of the hip joint, the acetabulum and the femoral head, which form the hip joint, are closely matched in morphology, which is a typical club and mortar joint.

Hip dislocation

In car accidents, violence is often high-speed and high-energy, and multiple traumas are not uncommon for this. According to the direction of the femoral head dislocation, it can be divided into anterior, posterior and central dislocations. Later dislocations are the most common. The dislocation of the hip joint is accompanied by acetabular fracture. Violence from the side directly strikes the trochanteric area of the femur. It can move the femoral head horizontally and pass through the medial wall of the acetabulum and enter the pelvic cavity. If the lower limb is injured when injured When in place, the femoral head is moved backwards, resulting in a posterior acetabular fracture. If the lower limbs are slightly abducted and externally rotated, the femoral head is moved upwards, resulting in an acetabular burst-type fragmentary fracture. The area was damaged.

1. A history of powerful violent trauma, usually a traffic accident or falling from high altitude.

2. There is a lot of bleeding in the posterior peritoneal space, and hemorrhagic shock can occur.

3. The wound is swollen, painful, and has difficulty moving. There is often a large hematoma on the outer side of the upper thigh. The shortening of the limb depends on the degree of femoral head depression.

4. It is not uncommon to have abdominal visceral injuries.

5, X-ray examination can understand the injury, CT examination can understand the three-dimensional concept of acetabular fractures.

Classification Hip joint dislocation can be divided into the following types: 1. Type I simple acetabular medial wall fracture (pubic part), the femoral head can be light or heavy from the pelvic cavity. 2. There is a fracture (type of ischia) in the back wall of type II, and the femoral head is exposed to the back. 3. Type III acetabular fractures (patella). 4. The acetabular fractures were all involved in type IV blasting fractures.

Treatment: Hip central dislocation can be treated with hypovolemic shock and abdominal visceral injury.

1. Type treatment of mild femoral head inward movement, no reduction in acetabular fracture is necessary, and bed rest for 10-12 weeks is required for short-term skin traction to relieve symptoms and femoral head inward movement. Bone traction reduction, femoral supracondylar traction is sometimes not effective. It is best to drill a large screw below the large tuberosity and pass through the femoral neck to the femoral head for lateral traction. The bedside film to verify the reduction, general traction 4 6 weeks and 3 months can bear weight. Those with poor reduction of acetabular fractures, those who cannot reset the femoral head, and those with femoral fractures on the same side need to be opened and reduced, and fixed with screws or special steel plates.

2. Type II-IV treatment: This type of injury has obvious acetabular damage and is difficult to treat. Generally, open reduction and proper internal fixation are recommended. In type IV cases, severe acetabular damage often results in traumatic osteoarthritis. If necessary, joint fusion or total hip replacement can be performed.

Avoid trauma.
