ABSTRACT

Introduction: The treatment of scoliosis of any cause in skeletally immature patients is a challenge because it must allow adequate growth and lung development. The objective of the study is to determine the prognostic variables related to complications of treatment of scoliosis in skeletally immature patients with growing rods. Material and methods: An analytical cross-sectional study with 58 patients from 2009 to 2014 was carried out. The age at treatment, etiology, preoperative Cobb angle and type of fixation were analysed as independent variables. The number of complications related to hardware was determined. Measures of central tendency and dispersion were calculated with confidence intervals of 95%. The value of statistical significance was set with χ² test. Results: An incidence of 66% of hardware related complications was observed; with significant differences in the incidence of complications according to the etiology, with neuromuscular patients presenting complications in 81% of the cases compared to 57% for other etiologies, a preoperative Cobb angle greater than 60o, a greater number of rods and proximal and distal fixation points was also inversely related to the number of complications. There was no difference in the incidence of complications according to age at treatment. Conclusions: The independent variables found to have a significant relationship with the presence of hardware related complications were: a neuromuscular etiology, a Cobb angle greater than 60o, the use of a single rod and the use of less than two proximal or distal fixation points.
