Controlled trial of distal radial fractures treated with a resorbable bone mineral substitute

Abstract

This randomized trial compared the use of hydroxyapatite cement with Kapandji wiring in distal radial fractures. Two groups of nine patients with distal radial fractures were either treated by reduction and fixation with wires or insertion of the cement into the fracture void. There was no difference between the groups before operation, on reduction or at day 1. Dorsal angle in the hydroxyapatite group was significantly worse at 6, 12 and 26 weeks. Grip strength and palmar flexion were poor in the hydroxyapatite cement group. All the clinical parameters and X-ray variables were worse at 12 and 26 weeks in the hydroxyapatite cement group. We conclude from this trial that there is nothing to support the use of this hydroxyapatite cement, without the use of additional fixation, in distal radial fractures.
