Cigarette smoking impedes tendon-to-bone healing

Copyright The Journal of Bone and Joint Surgery. Used with permission.Increased cell proliferation in the saline solution group (B) compared to the nicotine group (A)Orthopaedic surgery researchers at the School of Medicine have identified yet another reason not to smoke. Studying rotator cuff injury in rats, the research team found exposure to nicotine delays tendon-to-bone healing, suggesting this could cause failure of rotator cuff repair following surgery in human patients. This study, the first to evaluate the effects of nicotine on rotator cuff repair, found that inflammation persisted longer in the shoulder joints of rats exposed to nicotine. The researchers also noted less cellular proliferation and decreased collagen production, indications of poor healing.
