Biodegradable wire fixation in olecranon and patella fractures combined with biodegradable screws or plugs and compared with metallic fixation

Abstract

The outcome of olecranon and patella fractures fixed with biodegradable implants (self-reinforced poly-L-lactide wire combined with self-reinforced polyglycolide screw or self-reinforced poly-L-lactide plug) or with metallic implants (tension band wiring, Kirschner wire and metallic cerclage wire) was compared in a prospective, randomized study. Twenty-five olecranon fractures (15 with biodegradable implants and 10 with metallic ones) and 10 patella fractures (6 with biodegradable implants and 4 with metallic ones) were treated. There were no differences between these methods in outcome. Olecranon and patella fractures can be treated using biodegradable implants successfully. The total expenses are lower because a second operation is not needed to remove the implants after fracture consolidation.
