Predictive value of preoperative Fried Frailty Phenotype assessment and serum biomarkers on the prognosis of elderly patients with femoral neck fracture under general anesthesia within 3 months after surgery

Περίληψη

Background/aim: Femoral neck fracture (FNF) seriously impact the health of the elderly and affect their long-term quality of life of the patients. This study aimed to determine whether combining the preoperative Fried Frailty Phenotype (FFP) with serum fibroblast growth factor receptor 3 (FGFR3) and run-related transcription factor 2 (RUNX2) could better predict the prognosis of elderly patients with FNF 3 months after surgery.Materials and methods: A total of 150 elderly patients with FNF (60–89 years old) were enrolled and divided into a nonfrailty cohort and a frailty cohort based on preoperative FFP evaluation. The hip recovery of patients 3 months after surgery was evaluated using Harris Hip Score (HHS). Serum FGFR3 and RUNX2 levels were analyzed, and the relationship between HHS and serum FGFR3 and RUNX2 levels was evaluated. The specificity and sensitivity of FFP, serum FGFR3 and RUNX2 were evaluated using ROC curves before surgery. Potential prognostic factors were analyzed using multivariate logistic regression.Results: Serum FGFR3 and RUNX2 levels were lower and hip recovery was poorer in the frailty cohort than in the nonfrailty cohort (p < 0.001). Within 3 months after surgery, there were 12 deaths (17.6%) in the frailty cohort and 1 in the nonfrailty cohort (1.2%) (p < 0.001). FFP assessment combined with serum FGFR3 and RUNX2 levels had a higher diagnostic significance. Readmission and preoperative frailty phenotype were independent factors affecting the prognosis of patients with FNF. HHS scores greater than 70 and higher levels of serum FGFR3 and RUNX2 cutoff values (7.85 ng/mL and 56.5 ng/mL, respectively) were identified as protective factors for prognosis.Conclusion: Assessing FFP alongside serum FGFR3 and RUNX2 levels may aid in evaluating the prognosis of elderly patients with FNF 3 months after surgery.
