Between 1963 and 1971, Harrington's technique was used by the senior author to operate on 493 scoliotic patients, of which 364 were idiopathic. A total of 276 patients were re-examined, of which 209 were idiopathic cases. All met the following criteria : 1. A follow up period of at least 10 years, 2. The operation was performed by the same surgeon, and 3. The review was undertaken by one person. The average follow-up period was 13 years, 10 months. A total of 95 patients had a follow-up period of more than 15 years, of these 75 patients were idiopathic. The surgical technique was similar in all cases : a distraction rod in the concavity, arthrodesis by decortication and a corticospongious graft obtained from one or both iliac crests. Postoperative immobilization was assured by a plaster corset for 6 months, followed by a "plexidur corset lyonnais". The review of the patients examined was based on rigorous clinical and radiological analyses. Anteroposterior and lateral radiographs were obtained, complemented by a lateral radiograph of the lumbosacral segment. The angular results were disappointing, decreasing from 66.2° to 38° immediately 51.4°. Clinical results were good : only 21.3% of patients actually had back pain. The patients were satisfied with their appearance and their professional, social and marital status. This study indicates the outcome of the lumbar spine below the graft. The vertebral bodies were modified morphologically they became elongated and more trapezoidal leading to a quite normal average lordosis. A short kyphosis occurred when the lower hook rested on T12, L1 or L2. The authors thought that the best rest-level was L3 or L4. Low-back pain was not increased with this low rest-level.
