摘　　要：Bone graft may be needed to fill bone defect in elderly patients with a metaphyseal comminuted distal radius fracture. In this retrospective, nonrandomized, single-surgeon study, we evaluated the clinical and radiologic outcomes of using both dorsal locking plates with or without augmentation with mineralized collagen （MC） bone graft for elderly patients with dorsally metaphyseal comminuted radius fractures. Patients in group 1 （n = 12） were treated with dorsal locking plates with MC bone graft application into the metaphyseal bone defect, and those in group 2 （n - 12） only with dorsal locking plates. Clinical and radiologic parameters were determined at three and 12 months after surgery. At final follow-up, no significant difference was noted between the 2 groups in terms of palmar tilt and radial inclination （p - 0.80）; however, ulnar variance increased significantly in the group 2 treated with dorsal locking plates without augmentation （p〈0.05）. Functionally, there was no significant difference between the groups. Our preliminary study suggests that combination of MC as bone-graft substitutes and dorsal locking plates may be a usefully alternative for elderly patients with metaphyseal comminuted distal radius fracture.Bone graft may be needed to fill bone defect in elderly patients with a metaphyseal comminuted distal radius fracture.
