We reviewed 27 patients with small-fragment fractures or osteotomies treated by internal fixation with absorbable self-reinforced poly-L-lactide pins. The follow-up time ranged from eight to 37 months. The two most common indications were chevron osteotomy of the first metatarsal bone for hallux valgus and displaced fracture of the radial head. No redisplacements occurred, and there were no signs of inflammatory foreign-body reaction. Biopsy in two patients 20 and 37 months after implantation showed that no polymeric material remained.

Fifty-six patients with displaced malleolar fractures had open reduction and fixation of the fracture fragments using, by random selection, either biodegradable implants or metal AO plates and screws. The cylindrical biodegradable implants were made of polylactide-glycolide copolymer (polyglactin 910). The complications, radiographic results and functional recovery were studied prospectively. After follow-up of at least one year, no significant differences emerged in the complication rate or in the results of treatment between the two methods of fixation. Because of the advantage of avoiding the need to remove metal fixation after union, we now use biodegradable internal fixation routinely to treat displaced malleolar fractures.
