ABSTRACT
<p><b>OBJECTIVE</b>To evaluate clinical outcomes of growing rod technique in treating young children with congenital scoliosis.</p><p><b>METHODS</b>From August 2002 to October 2009, 34 patients with congenital scoliosis underwent growing rod procedures including 12 male and 22 female patients. Four patients underwent posterior correction surgeries with single growing rod (single growing rod group), 30 patients underwent posterior correction surgeries with dual growing rod(dual growing rod group). The average age at initial surgery was 6.9(2-13) years. Five patients with severe rigid deformity or kyphosis had an osteotomy at apex vertebra with short segmental fusion followed by dual growing rod technique. The analysis included age at initial surgery and final fusion (if applicable), number and frequency of lengthenings, and complications. Radiographic evaluation including scoliosis, trunk translation, length of T1-S1, thoracic kyphosis and lumbar lordosis was conducted.</p><p><b>RESULTS</b>The follow-up was 40.5 (24-110) months. In single growing rod group, the mean scoliosis Cobb angle improved from 80.9°to 59.5°after initial surgery and was 65.3°at the latest follow-up. T1-S1 length increased from average 24.3 cm to 26.0 cm after initial surgery, and to 31.1 cm at latest follow-up with an increase of 1.05 cm per year. The space available for lung ratio(SAL) in patients with thoracic curves improved from 0.81 to 0.92 at the latest follow-up. Three patients reached final fusion. Four complications occurred in 3 of the 4 patients. In dual growing rod group, the mean scoliosis Cobb angle improved from 72° ± 22°to 35 ± 14° after initial surgery and was 35 ± 17°at the last follow-up or post-final fusion. T1-S1 length increased from (25 ± 5) cm to (29 ± 5)cm after initial surgery and to (33 ± 5)cm at latest follow-up with an average T1-S1 length increase of 1.49 cm per year. The SAL in patients with thoracic curves improved from 0.84 ± 0.08 to 0.96 ± 0.06 at the latest follow-up. Three patients reached final fusion. Complications occurred in 7 of the 30 patients, and they had a total of 13 complications.</p><p><b>CONCLUSIONS</b>Growing rod technique is a safe and effective choice for young children of long, complex congenital scoliosis. It maintains correction achieved at initial surgery while allowing spinal growth to continue. Implants-related complications remain the biggest challenge.</p>
