Background: Vertebral compression fractures are the most common fragility fractures affecting osteoporotic patients. This study evaluated volume trends and outcomes across specialties performing cement augmentation procedures.
Methods: Patients were identified using Current Procedural Terminology codes for vertebroplasty or kyphoplasty from 2010 to 2019. Patients were grouped by surgical providers (orthopedic surgery and neurological surgery) or nonsurgical providers (anesthesia, pain medicine, radiology, and physical medicine and rehabilitation). Outcomes recorded included reoperation rates and postoperative complications occurring within 30 days. Logistic regression was employed to account for potential confounding variables, and odds ratios were obtained.
Results: Inclusion criteria were met by 80,864 patients who received cement augmentation. Surgeon specialists performed 51.7% of all procedures. Of procedures carried out by nonsurgeon specialists, radiologists performed the most. Despite a stable number of procedures performed over the period, the percentage of procedures performed by surgeons decreased from 58.8% to 49.9% (P < 0.001). Patients with procedures performed by surgeons experienced lower odds of reoperation at 30 days (P < 0.001) and 1 year (P < 0.001), but 5-year and overall rates were not significant (P > 0.05). Surgical patients had lower odds of acute kidney injury (P < 0.004) and pulmonary embolism (odds ratio = 0.62, P < 0.001), yet increased odds of surgical site infection (P < 0.001).
Conclusions: Kyphoplasties and vertebroplasties are increasingly performed by nonsurgeon specialists. Although early reoperation rates are higher for nonsurgeon specialists, 5-year and overall reoperation rates were similar. Differing complication rates may relate to patient selection rather than operative technique and can be investigated with future studies.
