Abstract
ABSTRACT Objective: To determine the efficacy and safety of growing rods in the treatment of scoliosis in children aged under 10 years. Methods: A retrospective review of medical records of patients under 10 with scoliosis, treated with growing rods from the period between 1997 and 2012. Results: We identified 35 patients treated with growing rods who met the selection criteria. The average age at the start of treatment was 5.9 ± 2.3 years. Most of the patients (51.4%) showed idiopathic etiology scoliosis. Pre-surgery and post-surgery radiographic change showed a 47.7% reduction in Cobb angle (p>0.001). We identified 8 patients with some complication, the most prevalent being instrumentation failure (22.9%). The only predicting factor for post-operative complications was the total number of lengthenings performed (OR=7.03; CI 95% [1.1-45.4]; p=0.040). Conclusions: Treatment of scoliosis with growing rods in patients aged under 10 achieved a significant reduction in the magnitude of the deformity before final bone fusion. However, the rate of complications is rather high, therefore we recommend reducing the frequency of lengthenings to the minimum needed to maintain correction and longitudinal growth of the spine. Level of Evidence IV; Case series.
