Osteotomy is mainly used to heal the deformity of bones or fracture deformity, and can be done by local X-ray examination to determine the degree of local bone deformity, and then choose the osteotomy plan. The cost of osteotomy treatment is usually about 30,000 RMB, which mainly includes surgery fee, anesthesia fee and examination fee, and these costs are about 10,000 RMB. In addition, after the osteotomy, internal fixation treatment is required, and the cost of internal fixation material is about 20,000 yuan. It takes at least 3 months to recover after the osteotomy, avoiding premature local force or blind weight-bearing, otherwise it may lead to fixation failure. Generally, X-rays of the osteotomy site will be reviewed every 2-3 months after surgery to understand the recovery situation.
