ABSTRACTMaterial and methods. A study of cohorts analytical of 74 patients taken part surgically with instrumentation via ridge of the column of any etiology, age was made and sex; divided in two groups of 37, to those who the later ligamentary system of the column was preserved to them and to those who I am not preserved to them; with a pursuit average of 30 months. The interest variable was the development of kyphosic deformity in the cephalic end of the instrumentation like radiological complication in the postoperating one, the statistical analysis was made by means of simple frequencies and inferencial statistic by means of the test "U" of Mann-Whitney and exact of Fisher test for the presence of kyphosis deformity and its degree in the postoperating one. Results: The medium one of the age of the patients was of 13.5 years (rank from 9 to 28), predominated feminine sex with 65%, the predominant etiology were the idhiopatic scoliosis with the 62,2% and the disease of Scheuermann with 14.8%. The group with preservation of the later ligamentary system of the column presented a smaller incidence of kyphosis postsurgical (p < 0.001) and minor loss of correction in degrees of the same one (p = 0.037). Conclusion: The preservation of the later ligamentary system of the column in patients under instrumentation later had a smaller incidence of kyphosic deformity postsurgical in the cephalic end of the same one in comparison with those patients in those who east ligamentary system was not preserved.
