ABSTRACT

Objective:

At least 5 - year follow up results of adolescent idiopathic scoliosis, those were treated using Cotrel- Dubousset instrumentation (CDI) and Luque sublaminar wiring methods we-re reviewed with retrospective cohort study. Re-sults of these two cohorts were compared.

Methods:

Twenty nine patients contain two cohorts were included in the study. Fourteen of patients were treated using CDI and fifteen we-re treated with Luque sublaminar wiring method. Mean age at the time of surgery was 15.3 years in CDI group and 17.7 for sublaminar wire gro-up. Preoperatively primary curves were measu-red using Cobb method, revealing a mean of 49.9 degrees for CDI group and 56.4 degrees for sublaminar wire group. At the end of follow up period, mean Cobb value was 15.6 for CDI group and 19.7 for sublaminar group.

Results:

Statistical analysis of the results re-vealed that there is no statistical difference bet-ween these two methods at follow up (p>0.05). During follow up period, for two patients in CDI group pull-out of proximal hook were encounte-red. In one of these patients revision was perfor-med.

Discussion:

From aspects of correction of deformity and maintenance of correction, com-parison of CDI and sublaminar wiring method showed that there is no difference between these two methods at the end of follow up period.
