Absorbable polyester pins and screws for the internal fixation of small fragment fractures have been commercially available for several years. The main advantage of these devices is that no implant removal procedures are required, which could result in financial savings. The current cost analysis, which included costs of medical care plus costs of lost time from work, was based on 994 fracture patients treated with absorbable internal fixation devices and 1173 patients operated on using conventional metallic devices. The fracture types studied were uni- and trimalleolar fractures of the ankle, fractures of the olecranon, and metacarpal fractures. When the costs for an implant removal procedure after metallic fixation were included, the average cost saved per patient by using absorbable implants varied from $410 in fractures of the olecranon to $903 in unimalleolar fractures. However, hardware removals often are optional. According to the results of this cost analysis, the break even point is attained at a removal rate of 19% for metacarpal fractures, 21% for unimalleolar fractures, 46% for fractures of the olecranon, and 54% for trimalleolar fractures. Only at a higher removal rate would the use of absorbable devices, with their current prices, be a financially more favorable alternative than the use of metallic ones.
