Background
Traction therapy is a method for applying external force to a certain part of a body or a joint to separate the body and the joint to a certain degree, and peripheral soft tissues are properly drafted, so that the treatment purpose is achieved. Traction therapy is divided into spinal traction and limb joint traction according to different traction positions by external force. An orthopedic traction instrument is a commonly used therapeutic instrument for orthopedics. The product can assist traction operation and improve traction effect. The principle of the treatment of the fracture of the lower leg is to recover the length of the lower leg, align and hold weight functions and heal bones, and the purpose of reduction is achieved by traction. For example, the lower leg traction of a femoral head necrosis patient has two meanings: one of the two parts is pulled by the shank to pull the hip joint gap open, so that the cartilage surface of the acetabulum and the cartilage surface of the femoral head are separated from each other, the cartilage surface with necrosis inflammation is rested, the pressure of the joint cavity is reduced, and a good repairing environment is created for the femoral head. When the traction is used, the contraction of muscles and soft tissues around the hip joint can be resisted, and particularly, the muscles are preferably in a stretching state under the condition of rest at night. For the patient with contracture phenomenon, the traction can play a role of loosening, and good effect can be obtained by persisting in the traction for a long time.
