Title : Insights on kyphoplasty: A retrospective analysis of intraoperative variables and patient demographics
Abstract:
Study design: Single Surgeon Observation Study: 77 patients with VCF undergoing kyphoplasty over 18 months. OBJECTIVE: To highlight the relationships between age, sex, and spinal levels treated by kyphoplasty with balloon pressure, volume, and cement volume.
Summary of background data: Vertebral compression fractures are common fragility fracture, comprising significant health care costs. Kyphoplasty is an accepted treatment option, however details of procedural aspects are less well established.
Methods: Kyphoplasty balloon pressure/volume, and cement volume were recorded. The inclusion criteria included acute/subacute osteoporotic fracture; exclusion criteria included non-osteoporotic fractures and previous surgery.
Results: A total of 141 levels were included in this study (54 thoracic, 87 lumbar). There were 77 patients; 61% female, 39% male. There was a statistically significant relationship between age and region (T vs. L spine) (p=.013). Mean inflation pressure was 152.5 PSI for thoracic spine and 147.5 PSI for lumbar spine. There was a significant correlation between age and mean pressure (p=0.0014). There was a statistically significant relationship between anatomic spinal groups and pressure (p=0.044).The mean balloon volume was 2.42 cc for the thoracic spine and 2.89 cc for the lumbar spine. Statistically significant relationships were identified between balloon volume and level (p=0.014) and age (p=0.003). No statistically significant correlation was found between balloon volume and sex. The mean cement volume was 2.27 cc for thoracic spine and 2.92 cc for lumbar spine. Cement volume demonstrated a significant relationship with spinal level (p<.001), sex (p = 0.0255) and age (p=0.034). Advanced age and males required higher cement volumes (p<.0001).
Conclusion: Age, sex, and spinal level significantly influence kyphoplasty components. Both thoracic and lumbar fractures have different procedural requirements, with greater lumbar spine demands. Variations in sex and age emphasize the importance of personalized surgical planning.
