Abstract: The goal of the treatment of early onset scoliosis (EOS) is to correct the deformity while allowing for spinal growth. The aim of this study was to determine the safety and effectiveness of a new type of growing rod system the growing spine profiler or GSP that may be used in single or dual technique.
From 2012 to 2016, 15 patients underwent growing rod surgery for correction of EOS as follow. 5 single and 10 dual growing rod procedures using the growing spine profiler system (GSP).
The etiology of the patients’ spinal deformities were as follows idiopathic (5), congenital (4) and neuromuscular (6).
Clinical evaluation included age, sex, diagnosis, follow-up, number and frequency of lengthenings, and complications. Radiographic evaluation included changes in Cobb's angle, kyphosis, coronal and sagittal balance, space available for the lung (SAL) ratio, apical vertebral translation, shoulder and pelvic obliquity and T1-S1 height.
Overall 46 lengthening procedures were performed, the average number of lengthening procedures being 3 per patient.
The average time between two lengthening procedures was 6 (5-7) months. non-lengthening surgeries were about 30 and was done mainly to correct a complication that had happened during the course of surgical correction these surgeries include debridement for deep infection. replacement of broken rods........etc and will be listed below
Average follow-up time was 20 months. The mean coronal Cobb angle was improved from 81.8° to 39°.
One patient underwent fusion surgery. his age was 9 years, with a follow-up of 6 months. The Cobb's angle before fusion was 100° that improved to 61°. There were about 2 complications per patient, Dual growing rods results in better deformity correction and stability of correction with an acceptable complication rate.
