Percutaneous Kyphoplasty Enhanced with Calcium and Zoledronic Acid for Managing Thoracolumbar Compression Fractures in Athletes with Osteoporosis and Fitness Concerns

ABSTRACT

Background: Athletes and fitness enthusiasts often encounter thoracolumbar compression fractures due to rigorous physical activities. Combining calcium (Ca) and zoledronic acid (ZOL) with percutaneous kyphoplasty (PKP) has shown promising clinical efficacy in elderly patients with osteoporotic thoracolumbar compression fractures (OTCF). However, the potential benefits of this approach in athletes and fitness enthusiasts require further investigation. Methods: We conducted a retrospective analysis of 295 athletes and fitness enthusiasts (mean age 75.91±3.74 years) with OTCF who underwent PKP. Patients were divided into three groups PKP+Ca (n=92), receiving 1500mg/d Ca carbonate post-surgery; PKP+ZOL (n=98), receiving 5mg ZOL intravenously post-surgery; and PKP+Ca+ZOL (n=105), administered with a combination of Ca and ZOL post-surgery. A two-year follow-up was conducted, and clinical and imaging data were recorded and analyzed before and after treatment. Results: There were no significant differences in general information, lumbar bone mineral density (BMD), visual analog scale (VAS), Oswestry dysfunction index (ODI), and bone marker levels among the three groups before treatment. In the 3rd, 6th, 12th, and 24th months post-treatment, the PKP+Ca+ZOL group exhibited higher vertebral heights compared to the PKP+Ca and PKP+ZOL groups. Additionally, in the 6th, 12th, and 24th months post-treatment, the PKP+Ca+ZOL group demonstrated lower kyphosis than the PKP+Ca and PKP+ZOL groups. Furthermore, in the 12th and 24th months post-treatment, the PKP+Ca+ZOL group had higher BMD values than the PKP+ZOL and PKP+Ca groups. VAS scores in the PKP+Ca+ZOL and PKP+ZOL groups were significantly lower than those in the PKP+Ca group. ODI scores and bone marker concentrations were also lower in the PKP+Ca+ZOL group compared to the other groups. (AU)
