Abstract: Objective To analyze the predictive value of serum levels of peroxisome proliferator activated receptor gamma coactivator-1α (PGC-1α) and Omentin-1 for postoperative hip joint dysfunction in the elderly patients with intertrochanteric fractures of the femur (IFF). Methods A total of 114 elderly patients with IFF who underwent surgical treatment in the Orthopedics Department of Shijiazhuang Third Hospital from June 2017 to June 2023 were enrolled in this study. Based on an 8-month follow-up after surgery, the patients were divided into poor prognosis group (30 cases) and good prognosis group (84 cases). The serum levels of PGC-1α and Omentin-1 were measured by enzyme linked immunosorbent assay. Multiple logistic regression (step forward method) was applied to analyze the influencing factors of postoperative hip joint dysfunction in the elderly patients with IFF. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of PGC-1α and Omentin-1 for postoperative hip joint dysfunction in the elderly patients with IFF, and the area under the curve (AUC) was calculated. Results The serum levels of PGC-1α and Omentin-1 in poor prognosis group were significantly lower than those in good prognosis group (P<0.01). There were significant differences in age, preoperative AO classification between the two groups (P<0.05). Multivariable logistic regression analysis showed that preoperative AO classification,the levels of PGC-1α and Omentin-1 were independent influencing factors for postoperative hip joint dysfunction in the elderly patients with IFF. The AUC of serum PGC-1α combined with Omentin-1 in predicting postoperative hip joint dysfunction was 0.942 (95%CI: 0.899-0.984), which was superior to those of PGC-1α alone(AUC=0.825, Z=2.468, P=0.014) and Omentin-1 alone (AUC=0.819, Z=2.500, P=0.012). Conclusions Serum levels of PGC-1α and Omentin-1 are down-regulated in the elderly IFF patients with postoperative hip joint dysfunction. The combination of the two indicators can improve the predictive value for hip joint dysfunction and provide clinical reference for prognosis.
