[Differential therapy for the rheumatoid thumb].
ABSTRACT The thumb frequently is involved in rheumatoid arthritis and often is a source of significant functional loss, pain, and deformity. Surgical intervention in patients with rheumatoid arthritis of the thumb should be based on the degree of radiological destruction according to Larsen, the natural course of the rheumatoid hand, the nature and stage of deformity as well as the status of tendons, ligaments, and adjacent joints. The goals of surgery are to relieve pain, increase motion, and restore thumb function. The timing for shoulder surgery should be early in the course of the disease, since it determines the long-term prognosis and the remaining surgical options. Treatment options, alone or in combination, include synovectomy, arthrodesis, arthroplasty, and tendon repair or transfer. Joint-preserving surgery is indicated in the early stages of radiological destruction according to Larsen classification O-III, whereas the late stages of destruction (Larsen IV-V) require reconstructive surgery. Especially in hand and finger arthritis, the "wait and see" strategy should no longer be followed. Close interdisciplinary cooperation between surgeon and rheumatologist is necessary for early therapeutic strategy, taking into account the functional unit of the whole upper extremity. The ultimate aim is to provide pain relief, improve function, enhance appearance, and slow the progression of disease. When the pathogenesis and pathoanatomy of the impaired rheumatoid thumb are appreciated, and appropriate treatment is selected, surgical intervention is likely to provide a favorable outcome for the patient.

ABSTRACT: FCR-sling resectional arthroplasty does not definitely prevent a proximalisation of the first metacarpal bone. Since power transmission of the thenar muscles requires a particular length of the thumb, does proximalisation lead to a reduction of grip strength of the hand? In a prospective study, hand-, key- and pinch-grip strength was compared to preoperative data. Pain intensity and thumb mobility were also examined. In comparison to preoperative data, the pain-free pinch grip improved 60% after three months and 100% after 12 months (p < 0.01). The maximum pinch grip improved 11% after three and 34% after 12 months (p < 0.01). The pain-free key grip improved 22% after three months and 50% after 12 months (p < 0.01). The maximum key grip showed a fair reduction after three months, but after 12 months the key pinch strength came up to preoperative level. The hand grip strength showed a statistically significant improvement of 9% after three months and 34% after 12 months (p < 0.01). After one year, 80% of the patients were completely painfree. There was no clinically relevant disturbance of thumb movement following surgery. Owing to proximalisation of the first metacarpal, a scapho-metacarpal distance of 5.3 (2-9) mm was measured. Despite proximalisation of the first metacarpal, a significant improvement of the grip strength was observed, which was rooted in simultaneous pain reduction.Handchirurgie · Mikrochirurgie · Plastische Chirurgie 06/2001; 33(3):171-5. · 0.54 Impact Factor

ABSTRACT: A review of radiographic evaluation of rheumatoid arthritis is given. Standard reference films are introduced for evaluation of rheumatoid arthritis and related conditions in the extremity joints. In this system, numerical evaluation of arthritis is given for individual joints in a patient.Acta radiologica: diagnosis 08/1977; 18(4):481-91. DOI:10.1016/S0363-5023(83)80241-X
