Pelvis and Hip Joint Locking Plate System

The hip joint is composed of the femoral head and the acetabulum facing each other, and belongs to the club and socket joint. Only the lunar surface of the acetabulum is covered with articular cartilage, and the acetabular fossa is full of fat, also known as Haversian glands, which can be squeezed out or inhaled with the increase or decrease of intra-articular pressure to maintain the balance of intra-articular pressure.

At the edge of the acetabulum there is a glenoid rim attached. Deepen the depth of the joint socket. There is a transverse acetabular ligament on the acetabular notch, and it forms a hole with the notch, through which nerves, blood vessels, etc. pass.

Pelvic fracture is a serious trauma, accounting for 1% to 3% of the total number of fractures. It is mostly caused by high-energy trauma. More than half are accompanied by comorbidities or multiple injuries, and the disability rate is as high as 50% to 60%. The most serious are traumatic hemorrhagic shock and combined injury of pelvic organs. Improper treatment has a high mortality rate of 10.2%. According to statistics, 50%～60% of pelvic fractures are caused by car accidents, 10%～20% are caused by pedestrians being hit, 10%～20% are motorcycle injuries, 8%～10% are falling from height, 3% ~6% are severe crush injuries.

Violent direct blows, falls from heights, vehicle impacts, crushing, etc. can all cause femoral fractures. When a femur fracture occurs, the lower limbs cannot move, the fracture site is severely swollen and painful, and deformities such as distortion or angulation may occur, and sometimes the length of the lower limbs may be shortened. If there is an open wound at the same time, the condition will be more serious, and the patient will often experience shock. The femur is the largest bone in the body. If it is not treated in time after the fracture, it can cause severe complications such as hemorrhage and nerve damage. Therefore, it must be fixed and bandaged quickly and correctly, and then sent to the hospital for treatment immediately.

Intracapsular fractures of the femoral neck are more common in elderly patients, but less in young people due to bone quality. If not properly treated, femoral neck fractures can lead to disability, and in severe cases can cause death. At present, there are many treatment strategies for femoral neck fractures, and the choice of treatment plan depends on the patient's age, mobility, medical complications and other related conditions.
