Musculoskeletal injuries related to the rotator cuff (RC) are frequent and account for up to 70% of shoulder pain problems. Lesions of the RC lead to weakness and pain (ref: Carr et al mfl) and untreated these lesions are acompanied by muscle degeneration modulated by inflammatory reactions that vary in intensity. Anti-inflammatory modalities such as NSAID and corticosteroids are commonly used as add ons to conservative treatment of RC tendon tears or RC tendon surgery, which are, however associated with high failure rates. The aim was to study the impact that a conventional TNF inhibitor and a super selective TNF inhibitor (Anti-TNF treatment) has on soft tissue inflammation and bone constituent parameters/connective tissue in a rotator cuff tear model.
