A review was performed of 86 cases of infantile idiopathic scoliosis treated between 1962 and 1979. The single primary curves were classified as resolving, stable, progressive with a low rib--vertebra angle difference (RVAD) and progressive with a high RVAD. Two single primary curves subsequently developed a second curve and 17 were double when first diagnosed. Prognosis was difficult to establish before the age of five years. Only 18 per cent of curves showing progression beyond 50 degrees reached that point before the age of four. Conversely, if a scoliosis of 50 degrees or more was present before the age of four it always progressed. A more favourable outcome was indicated by male sex, a left-sided curve, a low initial curve measurement, an RVAD of less than 20 degrees in the initial radiograph, and the onset of scoliosis in the first year of life.
对1962年至1979年间治疗的86例婴儿特发性脊柱侧凸病例进行了回顾。单一原发性曲线分为缓解型、稳定型、低肋骨-椎体角差（RVAD）进展型和高RVAD进展型。两条单一原发性曲线随后出现了第二条曲线，17例初诊时为双曲型。5岁前很难确定预后。只有18%超过50度进展的曲线在4岁前达到该度数。相反，如果4岁前存在50度或以上的脊柱侧凸，它总是会进展。男性、左侧曲线、初始曲线测量值低、初始X线片RVAD小于20度以及出生后第一年出现脊柱侧凸提示预后更有利。
