title: [Respiratory function in idiopathic scoliosis in adolescents treated by Harrington instrumentation with or without sublaminar segmental wiring].
abstract: The forced expiratory volume in one second (FEV1) and the forced vital capacity (FVC) of 40 adolescents with idiopathic scoliosis were studied before and after surgery. The values obtained are expressed as percentages of the predicted normal. Twenty-one patients underwent surgical correction of the curve with Harrington rods followed by cast and brace immobilisation for one and a half years (Group A). In the other 19 patients the Harrington rod was contoured in the sagittal plane and supplemented with segmented sublaminar wires to allow rapid post-operative mobilisation free of any orthosis (Group B). A negative correlation was found pre-operatively between the magnitude of the curve and the FEV1 and FVC. The post-operative pulmonary function showed no statistically significant improvement. Contouring the Harrington rod to improve kyphosis in Group B did not affect the outcome.
