Friday, October 8, 2010, 13:30-14:10Session B12: Shoulder ArthroplastySwanson-Prothesis in Bouchard Arthrose: Is Still Indicated ?*Khalaf Moussa - Westpfalz Teaching Hospital - Kusel, GermanyAbdull Kader Martini - Heidelberg University - Heidelberg, Germany*Email: kmoussa@gmx.deBackground: Bouchard -arthrose is often familial and affect predominantly females. It starts asacute inflammation of the soft tissue and with time may progress to severe deformity andlimitation of movement. In the early phases one of the most commen operation in themanagement is the synovialectomy. In late stages with severe destruction and deformity of thejoint arthrodesis can be carried out . However, arthrodesis may lead to severe loss of function.One of the most commonly and world wide used prothesis to maintain movement is theSwanson –spacer.Material and Methods: 20 Swanson-implants in 14 patients (12 female,2 male) wereevaluated subjectively and objectively using PIJA-score (Interphalangeal-joint –score)and Dash –score.. The follow period was 4.6 years ( range 1-11 years).Results: The IPJA-score ranged 8-14 points (median 11.8) and the median Dash- score was28 points.. Improvement of pain was oberserved in 90% of the cases. Flexion more than 30° in85% and full extention in 75%. Ulnar deviation was noted in 7 patients (35%), mostly of theindex finger. Fracture of the prothesis occurred only in 1 case. No loosening was observedradiologically.Discussion: Swansin prothesis is good alternative to arthrodesis and be restricted only in caseswhere the musculotendinous structures are intact. In cases where the index finger is affected,arthrodesis is preferred.file:///E|/ISTA2010-Abstracts.htm[12/7/2011 3:15:47 PM]
