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

This study divides the elderly population into two groups: the Elderly group and the Advanced age group. By observing the enhanced recovery after spinal fusion surgery in these two distinct age groups of elderly patients, risk factors affecting postoperative enhanced recovery will be identified. Detection index: Blood routine examination, blood biochemistry, coagulation function, imaging examination (X-ray, CT 3D reconstruction), Japanese Orthopaedic Association (JOA) score, visual analogue scale (VAS) pain score. The number of participants for all adverse events, serious adverse events, implant-related adverse events and drug-related serious adverse events, and the adverse events were summarized accordingly. The severity of adverse events will be rated according to NCI-CTCAE version 4.0.
