Premature epiphysial closure is an infrequent complication of Perthes' disease. Twenty-two patients with this condition are reviewed, three of whom were bilaterally affected. The aetiology, radiographic features and effect on function are discussed. The incidence of this complication can be reduced by an awareness of the clinical and radiographic signs which contra-indicate treatment by upper fermoral osteotomy.

Analysis was made of the results of two methods of treatment of progressive infantile idiopathic scoliosis: a group of forty-eight children treated by rib resection, localiser jackets and Milwaukee brace were compared with a 'control' group of nineteen children treated by localiser jackets and Milwaukee brace alone. This failed to show any significant difference between the two groups. Carefully controlled splintage was effective in slowing the rate of progression of most curves which was not significantly affected by the addition of rib resection.
