The Effect of Smoking on Spinal Fusion

Area of Science:

• Orthopedics
• Spine Surgery
• Bone Healing

Background:

• Spinal fusion surgery is a common procedure worldwide, aiming to alleviate pain and improve stability.
• Smoking is a known risk factor for various health issues and negatively impacts bone healing in spinal fusions.

Purpose of the Study:

• To analyze the biochemical and clinical effects of smoking on spinal fusion outcomes.
• To provide recommendations for surgeons to minimize smoking-related complications in patients.

Main Methods:

• Retrospective literature review utilizing the NCBI database.
• Comprehensive analysis of biochemical and clinical studies, including in vivo animal and human clinical research.

Main Results:

• Smoking elevates the risk of pseudoarthrosis (nonunion) in both lumbar and cervical spinal fusions.
• Increased risk of perioperative complications including infection, adjacent-segment pathology, and dysphagia.
• Potential interventions include nicotine replacement therapy and bone morphogenetic proteins (BMPs).

Conclusions:

• Smoking demonstrably increases perioperative complications, especially pseudoarthrosis, in spinal fusion patients.
• Smoking cessation for four weeks post-surgery is crucial.
• Surgical adjuncts like BMPs and further research into nicotine replacement therapy can reduce morbidity.
