Crooked legs need to take the following treatments: 1, first of all, go to the orthopedic department as soon as possible, to clarify the cause of deformity of the lower limbs, and then to deal with it. For example, in this case, there may be lower limb fracture, joint injury or bony deformity.2. For mild injury, like mild fracture or joint injury, conservative treatment can be taken. Conservative treatment requires the doctor to manipulate the patient to reset, and then use traction, plaster, support, splint and other ways to fix the lower limb. On this basis, it is necessary to supplement the use of anti-inflammatory, swelling, pain relief, and promote fracture healing drugs for treatment. 3, for more serious injuries, such as the presence of serious fractures or joint dislocation, surgical treatment is needed. For the fracture need to take surgical incision and internal fixation, and for the joint dislocation, need to make surgical incision, explore the damaged part, and then do the corresponding repair. 4, for serious bony deformity, or joint deformity, need to carry out the corresponding surgical correction. For example, the corresponding osteotomy can be done, or the deformed joints can be reset or joint replacement therapy.
