Impact of Preoperative Marijuana Use on Functional Recovery and Complications After Spinopelvic Fusion in Adult Spinal Deformity.

| Population | Human participants |
Complex spinopelvic fusion surgeries carry significant perioperative risks, and with cannabis use becoming more prevalent, surgeons need evidence-based guidance on whether preoperative marijuana use affects surgical outcomes. This study addresses a critical gap in orthopedic and neurosurgical literature by examining long-segment spinal fusions specifically.
This retrospective cohort study followed 155 adults undergoing posterior spinal fusion from pelvis to L2 or higher, comparing 34 marijuana users to 121 non-users over an 8-year period. While marijuana users had significantly higher rates of preoperative opioid dependence (64.7% vs 42.9%), the study found no statistically significant differences in functional recovery, complication rates, or other measured outcomes between groups. The research focused specifically on complex spinopelvic procedures, which represent some of the most extensive spinal surgeries performed. Notable limitations include the retrospective design and relatively small sample size of marijuana users.
“This data suggests that preoperative marijuana use may not be the perioperative risk factor that many spine surgeons have assumed it to be for these complex procedures. However, the higher opioid dependence rates among cannabis users remains a clinically relevant finding that requires careful preoperative planning.”

FAQ
Does preoperative marijuana use affect outcomes after major spinal fusion surgery?
Based on this study of 155 patients undergoing long-segment spinopelvic fusion, preoperative marijuana use was not associated with statistically significant differences in functional recovery or complications. This suggests that marijuana use alone may not be a major risk factor for poor surgical outcomes in complex spinal deformity procedures.
Should patients stop using marijuana before spinal fusion surgery?
While this study found no significant differences in outcomes, the decision should be individualized based on patient factors and surgeon preference. The study does not provide specific guidance on preoperative cessation, and patients should discuss their marijuana use openly with their surgical team for optimal perioperative planning.
Are marijuana users more likely to be dependent on opioids before spinal surgery?
Yes, this study found that marijuana users had significantly higher rates of preoperative opioid dependence (64.7% vs 42.9% in non-users). This association suggests that marijuana users may represent a population with more complex pain management needs requiring careful perioperative opioid planning.
Does marijuana use affect fusion rates or bone healing after spinal surgery?
The study summary indicates mixed results from previous research on fusion success, but this specific study did not report statistically significant differences in outcomes between marijuana users and non-users. However, the study focused on functional and clinical outcomes rather than detailed fusion assessment, so definitive conclusions about bone healing cannot be drawn.
How common is marijuana use among patients undergoing complex spinal surgery?
In this cohort, approximately 22% of patients (34 out of 155) reported preoperative marijuana use. This reflects the rising prevalence of marijuana use in the general population and highlights the importance of understanding its potential impact on surgical outcomes.
