Description
Technical Field
The invention relates to the field of hip joint reduction, in particular to a hip joint reduction device.
Background
The hip joint is an acetabular joint, surrounded by tough ligaments and strong muscle flap protection, and is therefore very stable. Only under the action of indirect violent force can dislocation through the weak area between ligaments. It is mostly caused by strong violence during working or traffic accidents. Posterior dislocation of femoral head dislocation located at the latter of Nelaton's line; in which the former is anterior dislocation. Torsion, lever or conduction violence may be induced. The conduction of violence causes the femoral head to impact the bottom of the acetabulum and to be pulled out of the pelvis, which is the central dislocation.
Hip dislocation should be treated as early as possible to prevent continued destruction of the soft tissue surrounding the hip joint and degeneration of the articular cartilage. Articular cartilage takes nutrients from the synovial fluid, which is pumped into the cartilage matrix during normal cartilage activity. Early replacement helps to restore the cartilage's nutrient source quickly. However, reduction therapy also requires years of experience, combined with standard procedures. Generally, the reduction is tried first, if the reduction is difficult, the reduction is changed to the reduction under lumbar anesthesia, which cannot be violent, and the reduction is also combined by a plurality of persons, and the reduction technique is proper and standard. If not standard, there is a risk of femoral neck fracture after reconstruction if the reduction is not proper. Once a fracture occurs, it causes pain to the patient, requires high treatment costs, and has more complications. Therefore, clinically, an auxiliary device capable of standardizing the reduction operation is needed to avoid the weakness or the non-standard of the lower limb reduction of the patient only depending on the hand and upper limb strength constraints of the doctor.
