The Risser plaster corset as the only method of correction in the surgical treatment of scoliosis. A study of 150 cases.

: The authors analyse a consecutive series of 150 vertebral arthrodeses for scoliosis in which Risser's plaster technique was used as the only method of achieving correction. The results are analysed in relation to the most important factors in order to make them suitable for comparison with similar cases treated by the Harrington instrumentation method, the main justification for which is the reduced period of immobilisation. The results of the Risser technique compare favourably with those of the Harrington technique, in addition to which they showed several advantages.
