Smokers Beware

Smoking and Bone Healing

Why are bones affected by smoking?


Bones are nourished by blood much like the other organs and tissues in your body. Nutrients, minerals, and oxygen are all supplied to the bones via the blood stream. Smoking elevates the levels of nicotine in your blood and this causes the blood vessels to constrict. Nicotine constricts blood vessels approximately 25% of their normal diameter. Because of the constriction of the vessels, decreased levels of nutrients are supplied to the bones. It is thought that this is the reason for the effect on bone healing, as the impending need for more oxygen and nutrients during fracture and osteotomy healing are not met, causing prolonged union time.

Evidence Based Medicine Review

"Cigarette smoking is detrimental to bony healing," said Dr. Franklin Chen, an orthopedics instructor at Northwestern University Medical School in Chicago, Illinois, and lead author of a report presented at the recent annual meeting of the American Academy of Orthopedic Surgeons (AAOS), held in New Orleans, Louisiana.
He and his colleagues focused on the 13-month healing rates of 54 patients who underwent surgery to help correct a specific type of (often work-related) wrist injury called symptomatic ulnar impaction syndrome. Chen says "95% of nonsmokers healed compared to 68% of smokers; this difference is statistically significant. The mean time to healing was 5 months for nonsmokers and 7.2 months for smokers." Previous studies have shown similar slower healing rates among smokers who have undergone spine or ankle fusion surgeries.

In essence: it is important to note that when I or any of the physicians at our office "lecture" to you about the cessation of smoking and it's direct impact on your healing potential, we are not just being mean. It's based on clinical evidence that is monumental for your optimal outcome. This can impact healing time in stress fractures and wound healing as well, so cessation is your best bet!!

We have even started a policy whereby we will NOT perform ANY elective surgery on a smoker unless you either stop smoking 1 month prior to date of surgery and stop for 3 months after the surgery is completed, or sign a "WAVER" which specifically states that you understand you are directly impacting your outcome and any and all unforseen complications (such as infection, ampuatation, nonunion, etc) are DIRECTLY related to NON COMPLIANCE.
