Shoulder pain is a common musculoskeletal complaint in the general population. The elderly population is often afflicted, and rotator cuff problems are among the most common causes of shoulder pain seen in primary care practices. The prevalence of shoulder pain in the elderly has been estimated to range from 21% to 27%, and the prevalence of rotator cuff tear increases with advanced age. The etiology of rotator cuff disease is likely multifactorial, including both extrinsic and intrinsic factors. Rotator cuff dysfunction encompasses a spectrum of pathological changes, ranging from impingement syndrome to rotator cuff tendonitis to rotator cuff tendon tear. In the elderly population, the clinical manifestations from rotator cuff dysfunction can translate into significant morbidity and disabilities, interfering with ability for self care and functional independence. The goals of managing rotator cuff disease are to regain normal shoulder function and biomechanics, and to improve functional abilities in elderly patients. Treatment can consist of various conservative therapies (including ice, simple exercises, medications), and progress to more intensive physical therapy and/or corticosteroid injections. Rotator cuff dysfunction is a common musculoskeletal disorder in elderly patients and is often underdiagnosed and undertreated. Physicians should be aware of the prevalence of rotator cuff disease in this population and provide early diagnosis and treatment to help preserve the functional ability and independence of older patients.
