Abstract
BackgroundThe growing rod technique was applied in the treatment of early onset scoliosis (EOS) with promising outcomes and many complications at the same time. We reviewed data from literatures to compare the results of single growing rods with dual growing rods to achieve a clear understanding of this technique.MethodsPubMed, Embase, MEDLINE, ScienceDirect, CNKI, Wanfang Data, and CQVIP were searched electronically until March 2016 using “growing rod” and “early onset scoliosis” as major search terms. Also, we manually searched other relevant conference proceedings. Two reviewers independently finished methodological quality assessment, data extraction, and calculations.ResultsSix retrospective trials were adopted in data analysis including 126 and 119 patients in the single and dual rod groups, respectively. Significantly better coronal correction rates were observed immediately after the initial operation (MD = −14.67; 95 % CI −20.97 to −8.37; P < 0.01; I2 = 0 %) and at the final follow-up (MD = −23.70; 95 % CI −45.87 to −1.52; P = 0.04; I2 = 82 %) in the dual rod group. Similarly, better lengthening of the T1–S1 height occurred in the dual rod group immediately after the initial operation (MD = −1.74; 95 % CI −2.62 to −0.85; P < 0.01; I2 = 0 %) and at final follow-up (MD = −3.8; 95 % CI −5.56 to −2.04; P < 0.001; I2 = 36 %). There were more complications about the implant in the single rod group, while wound problems were common in the other group.ConclusionsThe data of the current meta-analysis showed advantages in the coronal correction rate and lengthening by dual growing rods with fewer implant-related complications and more wound complications.
Highlights
The growing rod technique was applied in the treatment of early onset scoliosis (EOS) with promising outcomes and many complications at the same time
Children who suffer from this type of scoliosis will experience rapid spine curve deterioration and cardiopulmonary disfunction later [2]
The results have shown, that these methods may hinder the development of the chest wall and lead to cardiopulmonary disfunction [3]
Summary
The growing rod technique was applied in the treatment of early onset scoliosis (EOS) with promising outcomes and many complications at the same time. We reviewed data from literatures to compare the results of single growing rods with dual growing rods to achieve a clear understanding of this technique. Regardless of the etiology, early onset scoliosis (EOS) is a kind of scoliosis which attacks children before they are 5 years old [1]. Children who suffer from this type of scoliosis will experience rapid spine curve deterioration and cardiopulmonary disfunction later [2]. Timely treatment is needed to correct the scoliosis deformity and to offer patients more spine growth, less cardiopulmonary deficiency, and a better quality of life.
