Resumo:
Introduction: Some authors contest the use of conventional growing constructs in surgical treatment of early-onset scoliosis (EOS) due to repeated surgeries, high rate of complications and progressive lack of flexibility after 1-2 years. The aim of this study is to evaluate Cobb angle variation and trunk growth during growing rod treatment.
Methods: We reviewed data from all EOS patients treated with conventional growing rods in our Department, from 2008 to 2016. Cobb angle, T1-S1 distance and growth inside the device were measured, before and after procedures. The number and type of complications was also evaluated.
Results: We followed 23 patients, average age of 6 yo. EOS etiologies were idiopathic (n=9), neurological (n=4), neurofibromatosis (n=3), congenital (n=5) and metabolic (n=2). A total of 197 surgical interventions (8,6/patient) were performed. Devices used were conventional dual sliding rods (n=21) and VEPTR (n=2). After 6 years of follow-up mean Cobb angle improved from initial 68º to 42º. The S1-T1 length increased 69 mm. Lengthening inside inner devices was 44 mm. There were 45 complications (2/patient), most due to hardware failure. 11 cases required revision surgery.
Conclusion: Using this technique we were able to achieve a good Cobb correction as well as good S1-T1 length increase, despite the elevated complication and reoperation rates.
