The study was undertaken to compare the efficacy of Woodcast splints and plaster-of-Paris casts in maintaining correction following sequential manipulation of idiopathic clubfeet. In this randomized prospective trial, 23 idiopathic clubfeet were immobilized with plaster-of-Paris casts and 23 clubfeet were immobilized with a splint made of Woodcast that encircled only two-thirds the circumference of the limb. The number of casts or splints needed to obtain full correction, the frequency of cast or splint-related complications, and the time taken for application and removal of the casts and splints were compared.Aims

Congenital pseudarthrosis of the tibia (CPT)
is a rare but well recognised condition. Obtaining union of the pseudarthrosis
in these children is often difficult and may require several surgical
procedures. The treatment has changed significantly since the review
by Hardinge in 1972, but controversies continue as to the best form
of surgical treatment. This paper reviews these controversies. Cite this article:
We studied the natural history of Perthes’ disease in 62 children in whom the onset of symptoms was in adolescence. Three patterns of disease were noted, namely, late-onset pattern, segmental collapse, or destructive with failure of revascularisation. In the late-onset pattern, the disease followed the sequence of healing seen in younger children, but adequate epiphyseal remodelling did not occur. Consequently, the femoral head was never spherical after revascularisation. With segmental collapse, early and irreversible collapse of part of the epiphysis occurred with gross deformation of the femoral head. The destructive pattern was characterised by a failure of revascularisation and repair of the avascular epiphysis. The radiological outcome was poor in all three patterns. The poorest clinical results were found in the destructive type which was frequently associated with incapacitating pain requiring arthrodesis or excision arthroplasty within three years of onset of the disease.
We analysed the short-term outcome after varus osteotomy for Perthes’ disease in 48 older children from south-west India, comparing them with 30 historical controls. The children were between 7 and 12 years of age at the onset of the disease. All had stage-I or stage-II disease, with half or more of the epiphysis involved. The operated children had an open-wedge subtrochanteric varus osteotomy with derotation or extension and a trochanteric epiphyseodesis. Weight-bearing was avoided until late stage III. The non-operated children had been treated symptomatically by conservative methods. At the time of healing, 62.5% of the operated group had spherical femoral heads compared with 20% of those treated non-operatively (p <
0.001). Of the operated children with Catterall group-IV involvement, 48% had good results as against 24% of the non-operated group (p <
0.05). The percentage increase in the radius of the affected femoral head compared with the normal side was significantly lower in children who had operations (14.68 We have shown that the short-term results of early surgical containment in children over seven years of age are satisfactory.
