Femoral head necrosis is a common and frequently-occurring disease in orthopedics. After the occurrence of this disease, it is mainly divided into four stages. If the patient has reached the third or fourth stage, and the femoral head has collapsed or deformed, which has seriously affected the normal walking function, then the patient can apply for a disability certificate.

If you want to apply for a disability certificate, you need to go to a formal appraisal institution for appraisal before you can apply for a disability certificate. In fact, it is best to advise patients to actively go to the hospital for relevant examinations, and then give appropriate treatment measures according to the examination results. For example, patients can consider hip replacement for treatment, which can restore the normal walking function of patients.
