[Correction of scoliosis using plates. Results of 99 cases seen at a later time]

The authors have reviewed 99 scolioses with an average follow up of 4.5 years which had been corrected by plating. The complications were not infrequent, but were rarely severe. The best early mechanical results were obtained in low curves when the plating was sufficiently extensive. After one year follow up some secondary displacements of the device were seen, mainly in the thoracic region. The long term results were satisfactory both in terms of the angulation and the cosmetic and functional result, except in high thoracic curves. The causes of failure were analysed. It is concluded that this type of operation is worthwhile in idiopathic reducible low curves without rigid secondary curves. It may be applied to paralytic curves provided there is not severe lordosis.
