Research Abstract	We examined depths of bone (n = 16) and metal (n = 16) screwsby micro-CT and a digital caliper in a rabbit model of osteochondral fracture. Better results were observed on the depths of the screws when chondral fractures were treated with bone screws than when treated with metal screws.
