Figures & data
Figure 1. Biopsy from distal radial fracture 19 days after injury. An old, partly necrotic trabecula and woven bone forming without cartilage precursor within the marrow space.
Figure 2. Bone resorption and formation are coupled during remodeling, but not during the response to trauma.
Figure 3. The observation that microinstability of a screw may lead to resorption and gross loosening may explain the role of local fluid flow in bone resorption. Forces and hydrostatic pressure around a microunstable screw are not greater than around a fixed one, but local fluid flows are. Drawn from memory of a drawing by Perren.
