Absorbable fasteners for the fixation of ankle fractures

Bioabsorbable materials have been used for the treatment of fractures for more than a century. We reviewed the results of a combined series of 30 ankle fractures from Bad Hersfeld, Germany, and Louisville, Kentucky, using initially polyglycolide and more recently poly-L-lactide screws and rods. The results were comparable to treatment with metal screws. The advantage of bioabsorbable implants is they do not need operations to take them out. There was a low incidence of reaction around the screw heads, which was reduced further with the use of the newer self-reinforced poly-L-lactate screws. The technique for use of plastics is different than the methods for placement of metal screws. Bioabsorbables will have an increasing role in fracture fixation in the future.
