Bioresorbable implants may decrease complications in displaced distal radius fractures

Published results showed pediatric patients with severely displaced distal radius and forearm fractures may have fewer complications with bioresorbable intramedullary implants compared with Kirschner-wire osteosynthesis.
In the retrospective study, researchers categorized data for 94 pediatric patients with severely displaced distal forearm or metaphyseal radial fractures into groups based on whether they received biodegradable poly(l-lactide)-co-glycolide acid (PLGA) implants (ActivaPin, Bioretec; n=30) or one or two stainless steel Kirschner-wires (Sanatmetal), which were either buried under the skin (KW 1 group; n=40) or left outside the skin (KW 2 group; n=24) between January 2019 and January 2020. Researchers collected and compared the number of minor and major complications, as well as the need for repeated interventions between the three groups.
Although the two Kirschner-wire groups had no significant differences in complication rates, results showed patients who received the bioresorbable implant had significantly lower complication rates. Researchers noted patients in the KW 2 group had the most outpatient visits, followed by patients in the KW 1 group. The least number of outpatient visits were found among patients in the bioresorbable group.
Researchers found no differences in functional outcomes among all three groups no later than half a year after injury. All three groups had no signs of growth disturbance 1.5 years after injury, according to results. Researchers noted no second surgical intervention occurred in the bioresorbable group.
