Abstract
In this series absorbable fixation devices (screws and rods) made of self-reinforced poly-L-lactide (SR-PLLA) were used to stabilize arthrodesis in rheumatoid arthritis. These fixation devices have been used mainly in the fracture treatment or in the fixation of osteochondral lesions or osteotomies in hallux valgus operations. In arthrodesis of post-traumatic arthritis these devices have been used successfully. Fifty-three arthrodeses (18 in the wrist, 18 in the hand, 6 talocrural joint and 11 subtalar-calcaneocuboid-talonavicular joint) were performed for 47 patients using absorbable screws and rods between 1989 and 1994. Overall results in every group were good. There were 3 superficial infections and 2 nonunions (both talocrural arthrodesis). According to this study it seems that absorbable screws and rods are interesting alternative fixation devices in arthrodesis in rheumatoid arthritis.
