For those who sufferes from Back Pain
THE SPINE AND CIGARETTE SMOKING
Bone is a living tissue dependent on the functions and support provided by the other body systems. When these systems are not able to perform normally, bone is unable to rebuild itself. The formation of bone is particularly influenced by physical exercise and hormonal activity, both of which are adversely affected by cigarette smoking.
Many smokers have less physical endurance than nonsmokers, mainly due to decreased lung function. Cigarette smoking reduces the amount of oxygen in the blood and increases the level of harmful substances, such as carbon monoxide. This, combined with the effects of smoking on the heart and blood vessels, can limit the benefits from physical activity.
In men and women, cigarette smoking is known to influence hormone function. Smoking increases estrogen loss in women who are perimenopausal or postmenopausal. This can result in a loss of bone density and lead to osteoporosis. Osteoporosis causes bones to lose strength, becoming more fragile. This silent disease is responsible for many spine and hip fractures in the United States.
SPINAL FUSION AND CIGARETTE SMOKING
Spinal Fusion
Defined Spinal fusion is a surgical procedure used to join bony segments of the spine (e.g. vertebrae). In order for the fusion to heal, new bone growth must occur, bridging between the spinal segments. Sometimes fusion is combined with another surgical technique termed spinal instrumentation. Instrumentation consists of different types of medically designed hardware such as rods, hooks, wires, and screws that are attached to the spine. These devices provide immediate stability and hold the spine in proper position while the fusion heals.
Spinal fusion (also termed arthrodesis) can be performed at the cervical, thoracic, or lumbar levels of the spine. It takes months to heal. Your doctor may order post-operative radiographs (x-rays) to monitor the progress of this healing.
The long-term success of many types of spinal surgery is dependent upon successful spinal fusion. In fact, if the fusion does not heal, spinal surgery may have to be repeated. A failed fusion is termed a nonunion or pseudoarthrosis. Spinal instrumentation, although very strong, may even break if nonunion occurs. Needless to say, spine surgeons try to minimize the risk of this happening.
Cigarette Smoking and Failed Fusion
Certain factors have been found to affect the success of spinal fusion. Some of these factors include the patient's age, underlying medical conditions (e.g. diabetes, osteoporosis), and cigarette smoking. There is growing evidence that cigarette smoking adversely affects fusion. Smoking disrupts the normal function of basic body systems that contribute to bone formation and growth. As mentioned previously, new bone growth is necessary for a fusion to heal.
Research has demonstrated that habitual cigarette smoking leads to the breakdown of the spine to such a degree that fusion is often less successful when compared to similar procedures performed on non-smokers. In a study of patients undergoing anterior cervical fusion (fusion of the neck), it was observed that smokers had an increased rate of nonunion (up to 47%) as compared to non-smokers.1
Another study evaluated tobacco use in patients who underwent lumbar (low back) fusion. The patients who smoked had failed fusions in up to 40% of cases, compared to only 8% among non-smokers.2 Similar findings have been reported in other studies as well.
Post-Operative Infection
Cigarette smoking compromises the immune system and the body's other defense mechanisms, which can increase the patient's susceptibility to post-operative infection. A study conducted by Thalgott et al showed that cigarette smoking was a risk factor for infection following spinal fusion.3
CONCLUSION
Clearly, cigarette smoking is detrimental to spinal fusion. People who are facing fusion or any spinal surgery should make every effort to stop smoking. Quitting the habit beforehand will decrease the associated risks and increase the likelihood of a successful spinal fusion surgery.
Your physician recognizes the importance of smoking cessation and can provide information about available treatment options.

Unfortunately i am one of those person that has a Lumbar Herniated Disc, due to a gym injury and prevalent prolapsed disk, i am currently only 60% of what i was, and after more than a year since the spinal surgery i am still ladened with pain and on-going physical therapy.
Please do think about your health and future. most importantly your loved ones.
Sincerely yours
