Smoking cessation and bone healing: optimal cessation timing.

Area of Science:

• Orthopedic Surgery
• Public Health
• Bone Healing Research

Background:

• Smoking is a global health issue with substantial economic impact.
• Current and former smokers face increased surgical complications like infections, poor wound healing, and pulmonary issues.
• Musculoskeletal issues in smokers include higher fracture rates, nonunions, malunions, infections, and osteomyelitis.

Purpose of the Study:

• To analyze the temporal relationship between smoking cessation and bone healing in orthopedic surgery.
• To investigate pseudoarthrosis rates following spinal fusion in smokers.
• To discuss implications for risk stratification and adjunct therapies in orthopedic care.

Main Methods:

• Review of existing literature on smoking, surgical complications, and bone healing.
• Analysis of pseudoarthrosis rates in spinal fusion patients.
• Examination of temporal trends in bone healing post-cessation.

Main Results:

• Surgical complication rates decrease with longer preoperative smoking cessation periods.
• Approximately 4 weeks of cessation prior to surgery aligns complication rates with non-smokers.
• Evidence suggests bone healing follows a similar time-dependent recovery pattern as wound healing in relation to smoking.

Conclusions:

• Smoking cessation is critical for reducing perioperative complications and improving orthopedic outcomes.
• A 4-week cessation period appears to be a key threshold for mitigating risks.
• Further research is needed to clarify the bone healing timeline and optimize smoking cessation strategies in orthopedics.
