Comparison of costs in ankle fractures treated with absorbable or metallic fixation devices

The economic costs of ankle fractures treated operatively with self-reinforced polyglycolide acid (SR-PGA) screws, with self-reinforced poly-L-lactide acid (SR-PLLA) screws or with metallic implants was determined. All patients were divided into three groups according to the fixation material used. Open and otherwise complicated fractures were excluded. The total expense of operations in each group was taken into account. The average total cost of an ankle fracture fixed with SR-PGA screws was pound 3503. In the SR-PLLA group it was pound 3906, and in the metallic group it was pound 4514. Total expenses were pound 1011 higher in the metallic group than in the SR-PGA group, and consequently, expenses in the metallic group were pound 608 higher than in the SR-PLLA group. According to this study, it seems that absorbable fixation devices are more economical than metallic implants in operative treatment of ankle fractures though as part of the differences in total expense in this series is due to the age of the patients and other dissimilarities between these groups, the results have to be interpreted carefully.
