Volar PEEK plate for distal radius fracture: analysis of adverse events.

ABSTRACT

BACKGROUND: The aim of the present retrospective study was to evaluate complications following carbon-fiber-reinforced polyetheretherketon (CFR-PEEK) volar plating in distal radius fracture in a large cohort of patients. As an alternative to conventional metallic devices, CFR-PEEK plates have been introduced over the last few years. METHODS: We performed a retrospective study including all patients who were treated for distal radius fracture using a volar fixed-angle plate DiPHOS-RM (Lima Corporate, Udine, Italy). All CFR-PEEK plates implanted were reviewed between May 2012 and December 2017. Plate removal, second surgery and adverse events were collected by reviewing medical records. A total of 110 patients were included with a mean follow-up of 4 years. RESULTS: Adverse side effects were observed in 9 cases (8%), developed during or after treatment. The most frequent complication was represented by intraoperative plate rupture (4%). Infection was reported in one case. DISCUSSION: The rate of complications of PEEK volar plates seems to be similar to those occurring with plates of different materials. Advantages of PEEK plates are the absence of the cold-welding phenomenon and the absence of exuberant bone callus on the plate, ensuring an easy hardware removal. Intraoperative rupture remains the main complication correlated with PEEK material. These complications can be reduced with an accurate surgical technique, especially at the beginning of the learning curve. LEVEL OF EVIDENCE Therapeutic IV.
