The Surgical Management Trends of Osteoporotic Vertebral Compression Fractures: 5-year Experience in One Institution

Osteoporotic vertebral compression fractures (OVCFs) have gradually become a health threat to elderly individuals. Treatment options are controversial, and many challenges remain. Our study aimed to investigate the management trends of OVCFs at a single institution, covering all cases of OVCFs between January 1, 2016, and December 31, 2020. A total of 938 OVCF patients were reviewed, and OVCFs were most common in patients over 70 years old. The hospital stay, surgery haemorrhage rate and total cost decreased year by year. The number of patients with previous OVCFs varied from 123 in 2016 to 83 in 2020. The average bone mineral density (BMD) of the patients generally decreased year by year. In OVCF treatments, the rate of PV or PK increased from 93.86% in 2016 to 98.98% in 2020, while the rate of PV combined with pedicle fixation decreased from 6.14% in 2012 to 1.12% in 2020. Most patients were treated with bisphosphonates, and only 2 patients were treated with teriparatide. The visual analogue scale scores significantly improved at the final follow-up compared with the preoperative values. The rate of previous fractures was correlated with BMD, while there were no correlations with sex, age, or anti-osteoporosis treatment. In conclusion, the 5-year incidence of OVCFs increased and average patient BMD worsened by year. Although the total cost is continuously decreasing, poor adherence to anti-osteoporosis treatments and the prevention of refracture create more severe challenges.
