Previous studies have focused comparisons on coronal plane deformity with minimal attention to the sagittal profile. In this retrospective study, the authors aimed to compare the evolution of the sagittal spinal profile in early-onset scoliosis (EOS) treated with VEPTR versus GRI.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>The data for 11 patients with VEPTR and 22 with GRI were reviewed. All patients had more than 2 years\u2019 follow-up with more than 2 lengthening procedures. Radiographic measurements were performed before and after the index surgery and at the latest follow-up. The complications in both groups were recorded.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Patients in both groups had similar diagnoses, age at the index surgery, and number of lengthening procedures. The changes in the major coronal Cobb angle and T1\u2013S1 spinal height were not significantly different between the 2 groups. Compared with the GRI group, the VEPTR group had less correction in thoracic kyphosis (23% \u00b1 12% vs 44% \u00b1 16%, p &lt; 0.001) after the index surgery and experienced a greater correction loss in thoracic kyphosis (46% \u00b1 18% vs 11% \u00b1 8%, p &lt; 0.001) at the latest follow-up. Although the increase in the proximal junctional angle was not significantly different (VEPTR: 7\u00b0 \u00b1 4\u00b0 vs GRI: 8\u00b0 \u00b1 5\u00b0, p = 0.569), the incidence of proximal junctional kyphosis was relatively lower in the VEPTR group (VEPTR: 18.2% vs GRI: 22.7%). No significant changes in the spinopelvic parameters were observed, while the sagittal vertical axis showed a tendency toward a neutral position in both groups. The overall complication rate was higher in the VEPTR group than in the GRI group (72.7% vs 54.5%).<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>The VEPTR had coronal correction and spinal growth results similar to those with GRI. In the sagittal plane, however, the VEPTR was not comparable to the GRI in controlling thoracic kyphosis. Thus, for hyperkyphotic EOS patients, GRI is recommended over VEPTR.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2017.7.peds17233","type":"journal-article","created":{"date-parts":[[2017,10,6]],"date-time":"2017-10-06T13:57:20Z","timestamp":1507298240000},"page":"561-566","source":"Crossref","is-referenced-by-count":17,"title":["Evolution of the postoperative sagittal spinal profile in early-onset scoliosis: is there a difference between rib-based and spine-based growth-friendly instrumentation?"],"prefix":"10.3171","volume":"20","author":[{"given":"Zhonghui","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Song","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Qiu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zezhang","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xi","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liang","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xu","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"17 Suppl","key":"b1","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"S46","DOI":"10.1097\/01.brs.0000175190.08134.73","article-title":"Dual growing rod technique for the treatment of progressive early-onset scoliosis: a multicenter study","volume":"30","author":"Akbarnia BA","year":"2005","unstructured":"Akbarnia BA, Marks DS, Boachie-Adjei O, Thompson AG, Asher MA: Dual growing rod technique for the treatment of progressive early-onset scoliosis: a multicenter study.
