Cannabis Use in Orthopaedic Surgery: Effects on Fracture Healing, Opioid Requirements, and Clinical Outcomes.
Cannabis Use in Orthopaedic Surgery: Effects on Fracture Healing, Opioid Requirements, and Clinical Outcomes.
Narrative review synthesizes available evidence on cannabis effects in orthopedic surgery, highlighting knowledge gaps in fracture healing and perioperative outcomes.
This review consolidates scattered evidence showing the endocannabinoid system affects osteoclast and osteoblast function, suggesting biological plausibility for cannabis effects on bone healing. The comprehensive literature search methodology strengthens confidence in identifying existing evidence gaps.
Orthopedic surgeons increasingly encounter cannabis-using patients but lack clear guidance on perioperative management. This review provides a structured framework for understanding potential risks and benefits when cannabis meets bone healing and pain management protocols.

Current evidence suggests biological mechanisms exist for cannabis to influence bone healing, but clinical data remains insufficient for definitive perioperative recommendations. Clinicians need individualized risk-benefit discussions with cannabis-using orthopedic patients.
As a narrative review, this does not provide original data or quantitative meta-analysis of outcomes. The abstract does not reveal specific clinical recommendations or safety thresholds for cannabis use in orthopedic populations.
Narrative reviews are inherently subject to selection bias and interpretive framework of authors. The quality and consistency of underlying studies synthesized is unclear from the abstract alone.
This review likely represents the current state of knowledge synthesis rather than practice-changing evidence. Orthopedic providers should anticipate more cannabis-using patients while recognizing that definitive clinical guidance awaits better prospective studies.

FAQ
Does cannabis use affect bone fracture healing in orthopedic patients?
Experimental studies show that the endocannabinoid system influences osteoclast and osteoblast function, which are critical cells in bone formation and remodeling. However, current clinical evidence is limited and conflicting regarding whether cannabis use significantly impairs fracture healing outcomes. More research is needed to establish definitive clinical recommendations.
Can cannabis use reduce opioid requirements after orthopedic surgery?
Some evidence suggests cannabis may have opioid-sparing effects due to its analgesic properties and potential synergistic interactions with opioids. However, the clinical data on post-operative opioid reduction in orthopedic patients is still emerging and requires further investigation. The evidence is not yet strong enough to recommend cannabis as a standard opioid alternative.
Should I tell my orthopedic surgeon about my cannabis use before surgery?
Yes, you should disclose cannabis use to your surgical team as it may affect anesthesia requirements, pain management strategies, and potentially healing outcomes. Honest communication allows your healthcare providers to optimize your perioperative care and monitor for any potential complications. Cannabis use should be treated as any other medication or substance that could impact surgical outcomes.
What are the potential risks of using cannabis around the time of orthopedic surgery?
Potential risks include interactions with anesthesia, altered pain perception, possible impaired healing processes, and complications with post-operative monitoring. The endocannabinoid system’s role in bone metabolism suggests cannabis could theoretically affect fracture healing, though clinical significance remains unclear. Patients should discuss timing and dosing with their surgical team.
Is there enough evidence to guide clinical decisions about cannabis use in orthopedic patients?
Current evidence is insufficient to make definitive clinical recommendations, as this narrative review highlights significant knowledge gaps in the literature. Most available data comes from experimental and preclinical studies rather than robust clinical trials in orthopedic populations. Healthcare providers must make individualized decisions based on limited evidence while awaiting more comprehensive research.
