Screening and Prospective Cohort Study of Risk Factors for Enhanced Recovery After Spinal Fusion Surgery in Advanced Age Patient

Inclusion Criteria: 1. Informed consent signed and dated by subject or guardian 2. Commit to follow the research procedures and cooperate with the whole process of the study 3. The subjects are 60 years old or older, regardless of gender 4. Patients with degenerative spinal diseases requiring spinal fusion surgery 5. Generally in good physical condition 6. Able to adhere to and cooperate with research interventions, such as oral medication 7. In fertile women, contraception should be used for at least one month prior to screening, and they should commit to use contraception throughout the study period and continue until the specified time after the study Exclusion Criteria: 1. Acute infection 2. Congenital malformation 3. Abnormal anatomy or skeletal variation 4. Malignant tumor 5. The surgical area was locally infected with symptoms of local inflammation 6. Fever or leukocytosis 7. Morbid obesity 8. Pregnant and nursing women 9. Mental illness 10. Acute joint disease, bone resorption, osteopenia and/or osteoporosis. Osteoporosis is a relative contraindication, as this condition may limit the degree of correction that can be produced, the amount of mechanical fixation, and/or the quality of the bone graft 11. Patients who are unwilling to cooperate with post-operative treatment 12. Any time an implant is performed it interferes with the anatomy or intended physiological function of the patient
