While internal fixation with angle stable implants has become increasingly popular the use of bone graft substitutes has also been recommended to address comminution zones and thus increase stability. Whether a combination of both methods will improve clinical outcomes was the purpose of the study Methods The study was thus conducted as a prospective randomized clinical trial. 39 patients with unilateral intraarticular fractures of the distal radius were included and randomized to 2 groups one being treated with internal fixation only while the second group received an additional bone graft substitute. Results There was no statistical significance between both groups in functional and radiological results. The occurrence of complications did also not show statistical significance. Conclusions No advantage of additional granular bone graft substitutes could be seen in this study. Granular bone graft substitutes do not seem to provide extra stability if dorsal angle stable implants are used. Dorsal plates have considerable complication rates such as extensor tendon ruptures and development of CRPS. Fractures of the distal radius are the most common fractures in the upper extremity and treatment options have been controversially discussed throughout the literature. Closed reduction is almost always easy to achieve but is difficult to maintain resulting in a loss of reduction. Therefore treatment aims to prevent radial shortening malunion and articular incongruity as these factors are associated with poor outcomes 1 . .
