1. A study of the average rate of growth of the legs and trunk of 202 normal average maturing children is presented. 2. The annual growth of the limbs and trunk was related to the skeletal age of each child, and the increments of growth per skeletal year subjected to statistical analysis. 3. Methods of growth prediction of leg length and mature height have been derived and the practical application of the investigation to orthopaedic surgery is discussed.
1. The results are reported of a series of operations designed to stimulate growth of the bones of the lower limb by the insertion of pegs of bone or ivory close to the epiphysial cartilage. 2. The evidence is that growth was stimulated in twelve of twenty-eight patients. 3. Growth is more likely to be stimulated if the operation is done on children between the chronological ages of six and twelve.
