About

Diabetes mellitus is a group of metabolic diseases caused by multiple etiologies and characterized by chronic hyperglycemia. It seriously harms human health and has become a global public health challenge. Diabetes mellitus is present in 5% to 25% of patients undergoing spine surgery, and the prevalence has been increasing over the past decade. It is worth noting that spinal surgery for patients with diabetes has significant risks, mainly manifested in the significant increase of postoperative complications such as wound infection, delayed healing and wound hematoma, which seriously affect the long-term prognosis of patients' quality of life, spinal function and stability of internal fixation. Research shows that hypoglycemic drugs can not only control blood glucose level, but also affect the stability of nerve, bone and internal fixation, which is expected to improve the prognosis of spinal surgery in patients with diabetes. Metformin and sitagliptin are widely used hypoglycemic drugs. Studies have shown that metformin can increase bone mineral density in patients and have a protective effect on bones. Sitagliptin induces macrophage polarization of the M2 phenotype and reduces the impaired behavior of osteoblasts on titanium (TI) implants in a dose-dependent manner, thereby enhancing the bone regeneration required for successful orthopedic and dental implants in diabetic patients. However, the effects of these two drugs on the long-term prognosis of diabetic patients after spinal surgery, such as quality of life, spinal function and stability of internal fixation, have not been reported.

This investigation is a prospectie cohort study. The purpose of this study is to determine whether metformin and sitagliptin are associated with patient-reported outcomes and internal fixation stability at one year following elective spine surgery. Providers may use this information to help patients who need elective spinal surgery choose hypoglycemic drugs and to counsel patients with diabetes on expectations following spine surgery.
