Background:

the correction and stabilization of the deformity have developed a lot since the incorporation of lumbar pedicle screws, which are the gold standard of spinal instrumentation today.

Objective:

to describe the results of the modifications made to the hybrid instrumentation technique for the treatment of adolescent idiopathic scoliosis.

Methods:

a case series intervention study was carried out with 50 patients operated on for scoliosis in adolescence, divided into two groups. Group A composed of 31 patients, operated on with three different instrumentation techniques and group B composed of 19 patients operated with a hybrid instrumentation technique, modified by the author, in the province of Cienfuegos, in the period between January of 2013 and December 2017.

Results:

The 96% of the patients were female; the average age was 14 years old. In group A, the best results were achieved with full pedicle fixation with the 89.4% post-surgical correction; the 81.9% was achieved with the technique modified by the author, with minimal complications. Patient satisfaction was the 96% in group A and in patients in whom the author's modification was used, satisfaction was the 100%.

Conclusions:

the hybrid instrumentation system modified by the author achieves an excellent correction of the curve with a high degree of patient satisfaction.
