Abstract

Abstract: Background: Fracture is a common disease; many factors affect fracture healing. Recent studies have confirmed that hydrogen sulfide (H2 S) plays an essential role in bone formation, but most of these studies are drawing conclusions based on animal experiment; whether H2 S could promote fracture healing in patients is still unclear. We aim to investigate the change of serum H2 S in fracture patients, and analyze its effort on fracture healing. Methods: This is a single-center, prospective cohort study. Patients with spinal or limb fracture will be recruited. Patient's serum and urine will be collected at baseline for examination (serum H2 S, β-CTX, OC, PINP, 25-OH-VitD3, S-CTX, urinary calcium, and urinary creatinine). All patients will be followed-up for 24 months in outpatients settings, the image of X-ray or CT will be reviewed and fracture healing will be judged by 2 experienced orthopedic physicians. The difference in serum parameters especially H2 S will be compared between patients with fracture healed within 9 months and those with fracture unhealed at 9 months. Discussion: Results of the trial could provide insight into influence of H2 S on fracture healing. Ethics and dissemination: The study was approved by the ethics committee of School of Medicine UESTC & Sichuan Provincial People's Hospital Ethics Committee. All the participants will be asked to provide written informed consent before data collection. The findings of the study will be published in peer-reviewed journals and will be presented at national or international conferences.
