[Therapy of rheumatoid cubarthritis].

With the progression of rheumatoid arthritis (RA),more than half of the patients develop an affliction of the elbow.Cub arthritis has to be regarded as a part of systemic rheumatoid disease. Thus, the indication for operative treatment depends not only on local changes but is determined by the pattern of all affected joints, the activity of the basic rheumatic disease as well as the effect of physical therapy and medication. The complexity of the rheumatic disease, which typically affects many joints, demands an individual therapeutic plan that can only be developed and accomplished successfully when rheumatologists, rheumatoid surgeons and other specialists cooperate. In cases of recurrent cub arthritis,in spite of adequate medication, synoviorthesis or synovectomy should be performed. This may relieve pain and swelling,however if lesions of the cartilage already exist,progressive joint destruction cannot be prevented. Arthroscopic surgery of the elbow provides all of the known advantages of minimal traumatisation. In RA,it is used mainly when there is ligament laxity in late synovectomies eventually combined with arthroscopically assisted resection of caput radii. In contrast to monoarticular diseases in RA,the adjoining bursa olecrani, neighbouring joints and nerve entrapment syndromes also require treatment. The treatment for advanced cub arthritis is arthroplasty. Due to progress in the development of elbow endoprotheses, the range of indications for resection (interposition) arthroplasty has increased. It is now preferred mainly in younger patients with ankylosing arthritis. Rheumatoid changes in the bone and soft tissue impede the implantation of artificial joints and require time consuming and precise preparation techniques. When choosing either an unconstrained or semi-constrained prosthesis,one has to bear in mind the actual ligament stability and its often unpredictable changes during the course of the disease.Perioperative measures, postoperative care and therapy is made even more difficult due to the involvement of several joints, often extensive permanent medication, secondary lesions such as ldquo;corticoid skin" and in most cases the multimorbidity of patients after many years of chronic disease. When comparing elbow surgery in osteoarthritis and RA,we found that patients with RA clearly required more elaborate surgery and more extensive perioperative and postoperative care.
