Congenital dislocation of the hip joint, septic arthritis of the hip joint, ischemic necrosis of the femoral head, and failure of artificial hip joint replacement all end in destruction of the hip joint and loss of function, which seriously affects daily life, so artificial hip joint replacement becomes the most common and effective method to reconstruct the hip joint. However, since the artificial joint is a mechanical device with a certain service life, many patients have concerns about the surgery, fearing that they will have to operate again in the future, or that they will not be able to recover their functions after the joint is damaged, especially in younger patients. The Bayesian osteotomy of the proximal femur of the hip is similar to this method (Figures 1-3), but with the application of internal fixation, which has to be removed later, and without bone lengthening. The Ilizanov hip reconstruction is a good solution to this problem, as it can be done without hip replacement, can relieve pain and restore joint function, as well as effectively restore limb length, and is therefore an alternative technique for hip reconstruction. This technique was first invented and used by Dr. Elizarov in the former Soviet Union, hence the name “Elizarov hip reconstruction” (Figure 4). In this method, the femur is osteotomized using the Ilizanov technique and then fixed with an Ilizanov external fixation frame, and if the limb is shortened, the limb is lengthened at the same time to achieve length balance. After the operation, the hip joint function was restored, the range of motion was significantly increased, and the walking function improved significantly. This treatment method is less invasive, less risky, no foreign body implantation, natural reconstruction of the joint, and no recurrence problem. After surgery, the joint function is completely restored and there is no limitation of movement. You can walk on the ground 7-10 days after surgery. This method is suitable for patients aged 16-60 years old with congenital dislocation of the hip joint, sequelae of septic arthritis of the hip joint, advanced ischemic necrosis of the femoral head, and failure of artificial hip joint replacement.
