The usefulness of bioabsorbable magnesium implants in addition to metal plates in the treatment of complex distal radius fractures

Abstract

Purpose: The aim of this study was to determine whether normal plating yields comparable outcomes to plating using additional bioabsorbable screws or wires for complex distal radial fractures.Methods: Among 80 patients with complex distal radius fractures treated between January 2018 and March 2021, 45 were studied retrospectively and divided into two groups as follows: group A (n=23) received a plate, and group B (n=22) received a plate with a bioresorbable screw or wire. Radiological studies evaluated the period of bone union, radial length, inclination, and resorption of the bioresorbable screws or wires after surgery. The Disabilities of the Arm, Shoulder, and Hand (DASH) score was examined for clinical evaluation, and complications were compared between the two groups.Results: The two groups showed similar distributions in sex, age, injury mechanism, diabetes mellitus, smoking, and mean follow-up period; however, there were no statistically significant differences in the period of bone union and maintenance of reduction (radial length, inclination, and volar tilt). The DASH score averaged 14.8 and 13.2 points in groups A and B, respectively, showing no significant difference in complications (nonunion, malunion, infection, and arthritis).Conclusion: Regardless of the use of additional bioresorbable screws or wires, reduction in distal radius fractures in both groups yielded good results. Plating with additional bioresorbable screws or wires may be a suitable fixation method to compensate for the shortcomings of metal implants in complex distal radius fractures.
