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 Washington University School of Medicine in St. Louis 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. More…

Range of motion limited in professional baseball pitchers

Pitchers often lose range of motion in their pitching elbows.Now that the Chicago White Sox have swept the Houston Astros in the World Series, most baseball players are taking some time to rest. Time off is especially important for pitchers because throwing a baseball overhand is both an unnatural motion and a burden on the shoulder and elbow. Now a research team led by Washington University sports medicine specialists has found that professional pitchers have significantly decreased range of motion in their throwing elbows.

Pitchers often lose range of motion in their pitching elbows.Now that the Chicago White Sox have swept the Houston Astros in the World Series, most baseball players are taking some time to rest. Time off is especially important for pitchers because throwing a baseball overhand is both an unnatural motion and a burden on the shoulder and elbow. Now a research team led by Washington University sports medicine specialists has found that professional pitchers have significantly decreased range of motion in their throwing elbows. But that limited range of motion doesn’t seem to be influenced by the age of the pitcher, how many innings he has pitched or whether he has a history of injuries.

Orthopaedic surgeons preserve hip joint in young adult patients

Surgeons cut and reposition hip bones to reduce pain.When an older person has a hip problem, surgeons often replace the damaged hip with an artificial one. But that’s not a good option for someone in their 20s or 30s, so orthopaedic surgeons at the School of Medicine are repairing damage to the hip to prevent arthritis without having to replace the hip joint.
