Due to the frequent presence of comorbidities in patients suffering from rheumatism with increased perioperative risk factors, conservative treatment is often needed. Besides pharmacological treatment, physiotherapy and occupational therapy, a variety of orthoses are available depending on the individual indications. They can be used to stabilize or support joints, limit the range of motion, prevent unphysiological movements or provide relief for affected limbs. In order to choose the right kind of orthosis, the physician should know the underlying cause of disease. Furthermore, for patients with rheumatism many devices are available for daily living that use ergonomic handles or improved leverage effects to compensate for the often severe limitations and to improve the quality of life.
