A prospective study of 141 patients with 143 tibial shaft fractures has been carried out; 102 fractures were closed and 41 open. All the patients were treated by Ender's nailing and early weight-bearing. The average healing time was 15.2 weeks. There were no cases of bone infection and complications were minimal, the commonest being slight malalignment. Using this method, rapid restoration of bone continuity was achieved, combined with almost normal limb function during treatment.

A randomly selected sample of 3494 children evenly representing a total population of 37 391 schoolchildren aged between eleven and twelve was screened for idiopathic scoliosis by the bending test. Ten per cent of the children showed clinical evidence of scoliosis and 6.4 per cent had positive radiological findings. Small curves were equally distributed between the two sexes, while large ones were more common in girls. Children with fair hair and blue eyes showed a higher percentage of positive findings than children with a dark complexion. A group of 112 children with curves between 7 and 16 degrees were followed up for an average of nineteen months. The pattern and evolution of these curves showed their close relationship to established scoliosis. Potential factors of instability and deterioration of the curves were evaluated.
