标题：Change in Alignment of the Lower Limbs after the Fracture of Femoral Diaphysis in the Childhood-With respect to influence of loading on the form of the lower limbs-
摘要：Alignment of the lower limbs of twenty-one infants who suffered from the fracture of femoral diaphysis was examined from the viewpoint of both the change in growth of the major axis of leg, expecially concerning its overgrowth, and the deformation of the lower limbs, determined by the roentgenogram. The changes in growth of the major axis of leg were: 1)overgrowth in one year after the fracture was remarkable, 2)the severer shortening of bone occurred, the more remarkable overgrowth was observed, 3)with the decrease of difference in length of the limbs, overgrowth had a tendency to weaken, 4)approximately 80% of the all cases examined indicated overgrowth in crural bone adjacent to femur. The function axis of the lower limbs had already been in the normal position even in the period when the dislocation of the fracture point by flexion was not completely self-corrected. The dislocation was corrected at the point of metaphysis two or three months after the loading. In this study, the secondeary change in growth, overgrowth and deformation of the lower limbs, was considered to have a correlation with the loading volume and change in loading lines.
