A series of9S patients withjuvenile idiopathic scoliosis have been analysed. This showed that between the ages offour and six there was a higher incidence in boys whereas between seven and nine years of age, the proportion ofgirls was higher. Regardless ofsex and age the majority ofthe curves were convex to the right and the single thoracic curve was the commonest pattern. Spontaneous resolution occurred in seven patients: in four the curves resolved within two years; in the three others the curves resolved in three, four and five years respectively. Forty-four per cent of all patients were managed conservatively and in 56 per cent spinal fusion was carried between 1951 and 1979.
