This item covers developments relevant to cannabis medicine and clinical practice. Clinicians monitoring evidence in this area should review the source material.
With the rising prevalence of marijuana use and increasing rates of complex spinal deformity surgeries, understanding the impact of cannabis on perioperative outcomes is crucial. Previous studies yield mixed results on fusion success, complications, and opioid use in spine surgery, but none have focused on long-segment spinopelvic fusions. This retrospective cohort study analyzed 155 adult patients undergoing posterior spinal fusion from the pelvis to L2 or higher between 2015 and 2023. Patients were stratified by preoperative marijuana use (n = 34 users vs n = 121 nonusers). Baseline demographics, surgical parameters, clinical outcomes [Oswestry Disability Index (ODI), visual analog scale], radiographic measures (pelvic tilt, lumbar lordosis, and sagittal vertical axis), and complications were compared using Marijuana users had higher preoperative opioid dependence (64.7% vs 42.9%, In this cohort, preoperative marijuana use was not associated with statistically significant differences

FAQ
What question about marijuana and spine surgery did this study address?
Previous studies have produced mixed results on fusion success, complications, and opioid use in spine surgery, but none had focused on long-segment spinopelvic fusions. With marijuana use becoming more common and complex spinal deformity surgeries increasing, this study looked at how preoperative marijuana use relates to recovery and complications after these extensive fusions.
Which patients were included in this spinal fusion study?
The retrospective cohort included 155 adult spinal deformity patients who underwent posterior spinal fusion extending from the pelvis to L2 or higher between 2015 and 2023. Patients were grouped by preoperative marijuana use, with 34 users and 121 nonusers, and the two groups were then compared.
What outcomes did researchers compare between marijuana users and nonusers?
The researchers compared baseline demographics, surgical parameters, and clinical outcomes measured with the Oswestry Disability Index and a visual analog scale. They also compared radiographic measures of spinal alignment, namely pelvic tilt, lumbar lordosis, and sagittal vertical axis, as well as complications after surgery.
Were marijuana users more likely to be dependent on opioids before surgery?
Yes. Opioid dependence before surgery was more common among marijuana users, at 64.7%, than among nonusers, at 42.9%. This was a difference between the groups before the operation took place, so it describes the patients going into surgery rather than an effect of the surgery itself.
