Abstract
OBJECTIVES: This study aims to investigate the predictive value of bone morphogenetic protein-7 (BMP-7), thromboxane A2 (TXA2), and osteoprotegerin (OPG) for the prognosis of patients with distal radius fractures. PATIENTS AND METHODS: Between January 2021 and January 2022, a total of 124 patients (71 males, 53 females; mean age: 49.8±5.1 years; range, 34 to 68 years) with distal radius fractures were included in the fracture group. Healthy volunteers receiving physical examination in our hospital in the same period were included in the control group (n=50; 29 males, 21 females; mean age: 50.1±5.4 years; range, 35 to 68 years). The expressions of BMP-7, TXA2, and OPG in the peripheral blood were detected. In the fracture group, 124 patients underwent internal fixation after inclusion and followed for six months. The prognosis was evaluated based on the Gartland & Werley scoring system for wrist joint function. The factors influencing prognosis were analyzed, and the predictive values of BMP-7, TXA2, and OPG were calculated. RESULTS: Age, fracture classification, early loss of palmar tilt, late loss of palmar tilt, time to return to exercise after surgery, BMP-7, TXA2, and OPG were all factors influencing the prognosis (p<0.05). For predicting the prognosis, the area under the ROC curve of BMP-7 + TXA2 + OPG (0.928) was significantly larger than those of BMP-7 (0.810), TXA2 (0.856) and OPG (0.823) alone, and BMP-7 + TXA2 + OPG had the highest predictive efficiency. The BMP-7 was negatively correlated with TXA2 (r=-0.471), but positively correlated with OPG (r=0.437). CONCLUSION: The combined detection of BMP-7, OPG, and TXA2 is highly valuable for predicting the prognosis of patients with distal radius fractures.
