Preoperative Evaluation of Osteoporosis in Spinal Fusion Surgery: A Survey of Argentine and Latin American Surgeons
Abstract
Objective: To analyze the preoperative evaluation of osteoporosis during surgical planning for adult patients undergoing spinal fusion surgery, from the perspective of spine surgeons in Argentina and Latin America. Materials and Methods: A descriptive, cross-sectional study was conducted among orthopedic spine surgeons practicing in Argentina and other Latin American countries. A structured questionnaire based on a simulated clinical case was developed to explore preoperative management of a 70-year-old patient scheduled for elective spinal fusion surgery. Results: A total of 154 spine surgeons from Argentina, Brazil, Paraguay, and Uruguay were surveyed. Significant differences were found in the use of full-length spine radiographs (p < 0.001), dynamic radiographs (p = 0.001), computed tomography (p = 0.002), magnetic resonance imaging (p < 0.001), and Hounsfield unit assessment (p = 0.014). The use of bone density scans showed a marginal statistical trend (p = 0.058), with higher rates in Uruguay (52.4%) and Argentina (42.9%). Vitamin D testing was requested in 40.3% of cases, with no significant differences between countries (p = 0.803), highlighting the limited assessment of this marker related to bone metabolism. Conclusions: There is a clear trend toward underestimation of osteoporosis screening in the preoperative evaluation for spinal fusion surgery. Fewer than 50% of surgeons considered requesting a DEXA scan, Hounsfield unit assessment, or vitamin D measurement.Downloads
