Immobilisierung und Frühmobilisierung von Malleolarfrakturen nach Osteosynthese mit resorbierbaren Schrauben

71 patients with displaced ankle fracture were treated by using absorbable screws in the fixation of fractures. The follow-up time was 17 (13 to 33) months in average. The fixation devices were SR-PLLA (self-reinforced poly-L-lactide) and SR-PGA (self-reinforced polyglycolide) screws. 38 of the ankle fractures were immobilized with plaster cast and 33 ankle joints were mobilized immediately with a brace. An exact radiological result was achieved in 66 cases, insignificant displacement was observed in four cases and the result was poor in one patient. The result was classified as excellent in 62 patients, as good in eight patients and as poor in one patient. The patients treated postoperatively without plaster healed in a somewhat shorter time, but at one year check-up the differences in the clinical results were almost eliminated. Selected ankle fractures fixed with absorbable screws can be treated postoperatively with early mobilization without plaster.
