[A clinical study on lateral deviation of the line of gravity in idiopathic scoliosis].

The static deviation of the line of gravity in normal adolescent children and idiopathic scoliosis patients was analyzed. The following results were obtained: 1) The line of gravity deviated 1.3 cm to the left in the control. 2) The line of gravity in the right-convex single curve group was characterized as follows: It deviated to the right compared to the control, and it deviated further in severe cases. Brace treatment had no effect on the correction of the deviation. No difference was noted in the deviation between the thoracic and the lumbar curve group. 3) The line of gravity in the double curve group deviated slightly to the right, but that in the left convex single curve group was similar to the control. 4) The of gravity in the right-convex single curve group who underwent surgical treatment was corrected to the left.
