Technical Field
The utility model belongs to the technical field of orthopedics medical instrument, a pressure device of each joint of supine position state backbone and low limbs is related to.
Background
Knee osteoarthritis is the most common knee joint disease and is characterized by bending deformation of legs, such as O-shaped legs or X-shaped legs, which can cause symptoms of pain, movement disorder and the like, and is an important cause of disability of middle-aged and elderly people. The main causes of patients suffering from knee osteoarthritis are the changes of the lower limb force lines caused by the asymmetric height of the inner and outer gaps of the knee joint due to the degeneration, degeneration and abrasion of the articular cartilage and the subsequent change of the cartilage thickness. Changes in the lower limb force lines can lead to increased cartilage damage and the appearance of a vicious circle.
The lower limb force line is an important reference index for diagnosis and treatment of knee osteoarthritis. When the force line of the lower limb is measured, the line connecting the center point of the hip joint and the center point of the ankle joint in the vertical position of the load is called the force line, namely the mechanical axis of the lower limb. In the case of a human body under load and non-load conditions, the force lines of the lower limbs change due to the difference in the degree of ligament relaxation around the knee joint and the state of subchondral bone contact between the gaps of the knee joint under load and non-load conditions.
In the natural supine position, the hip, knee, ankle joints are not stressed, so that the actual state of the lower limb force line cannot be reflected, and the condition of intervertebral disc protrusion in the stressed position and the non-stressed position is different, so that the examination results are different. Therefore, the accuracy of the diagnosis and treatment results of the disease can be affected in the natural supine position.
Generally, the method for measuring the lower limb force line is to take a picture and image by an X-ray machine and then measure the lower limb force line in a load-bearing upright position, wherein a full-length piece of the load-bearing upright position, which comprises a hip joint, a knee joint and an ankle joint, has a measurement value on the same plane image. However, the number of hospitals with the technical equipment is small at present, the X-ray films which can be shot by general hospitals are relatively limited, the included range is limited, and a complete lower limb full-length film cannot be imaged, so that the X-ray films have no significance for clinical measurement. While full-length slices can be acquired in the same way in CT, the CT examination is acquired in a natural supine position, and the required accurate data cannot be acquired despite the presence of the image. In addition, in the case of orthopedic treatment, also in the supine position, intraoperative fluoroscopy still requires a force line in the weight-bearing upright position to be obtained for practical value.
