RESUMEN
The authors present their own experience in the intersomatic arthrodesis for severe scolioses, with or without means of osteosynthesis. The indication for this intervention is justified only as an atribute of absolute "vital indication". This surgery is far-reaching, requires an accurate technique, well adjusted instruments and conditions of advanced intensive care. The results were satisfactory both for the correction of the gibbosity but especially for the functional recuperation of the restrictive, respiratory insufficiency. 45 patients, out of whom 9 required an arthrodesis with an original model of thready rod, benefited from anl intersomatic osteotomy. We noticed that a progressive correction of the primitive upper concavity can be obtained by a osteotomy not larger than 4 disks; the patients to whom a spring for permanent compression was set profited by a satisfactory progressive correction.
