STUDY FINDS SUCCESS IN TREATMENT FOR FROZEN SHOULDER.
Promising results of a new study by ONS orthopedic shoulder surgeon Katherine Vadasdi, MD and other researchers were published this month in the Journal of Shoulder and Elbow Surgery. The study, The Effect of Myofibroblasts and Corticosteroid Injections in Adhesive Capsulitis, was conducted to investigate the effect that steroid injections administered directly into the shoulder joint would have on the painful and limiting condition called Adhesive Capsulitis.
Also known as Frozen Shoulder, Adhesive Capsulitis is a common, severely painful condition that leads to stiffness and reduced range of motion in the joint. In the study, Dr. Vadasdi and the research team evaluated the changes in the lining of the joint that contributes to or causes Frozen Shoulder. They discovered an increase in a certain cell type called myofibroblasts, which cause the capsule surrounding the shoulder joint to contact and form scar tissue, leading to pain and increasing stiffness. Steroid injections directly into the joint, however, reduced the increase in myofibroblasts, and helped reverse and prevent progression of the condition.
Frozen Shoulder most commonly affects women between the ages of 40 and 60 years. Most cases of Frozen Shoulder can be resolved non-operatively through stretching, physical therapy, anti-inflammatory medications and cortisone injections. In severe cases, a procedure known as arthroscopic capsular release is performed to break up the adhesions. The findings in Dr. Vadasdi’s study suggest a more rapid resolution of the condition and possibly a decrease in cases needing surgery.
