The hypoplastic type in adults (com-monly called osteomalacia) may be local-ized or general. There is thinning of thecortex and absorption of lime salts withoutproliferative changes or deformity. In the hyperplastic type in adults mul-tiple fractures are not common. We haveproliferation and lying-down of the newbone along with the destructive process. 512 Osteomalacia The trabeculse are coarse and bones are large, bowed and deformed—the picture seen in typical cases ofPagets disease. Of course, there are cases which fall be-tween these groups; but usually one orthe other forms will predominat
