Methods: This is a retrospective review of pediatric spinal deformity cases performed by a single surgeon from January 2008 to December 2012. One hundred thirty-six pediatric deformity patient charts were reviewed for inclusion into the study. All 136 patients reviewed had been operatively managed for a spinal deformity and were younger than 18 years of age. Our study's inclusion criteria comprised patients with a kyphosis greater than 60°, the use of sublaminar polyester bands in a hybrid surgical construct, and a minimum of 2 years of follow-up. Of the 136 spinal deformity cases reviewed, 17 cases met our inclusion criteria. No cases were excluded because of technical difficulty of band placement or for not using a hybrid construct with sublaminar bands (as it was the primary surgeon's principal construct of choice). PJK was defined as proximal junction sagittal Cobb angle (PJA) of at least 10° greater than the preoperative measurement. This was assessed by comparison of preoperative and postoperative radiographs. Our hypothesis was that PSF performed with our technique would have a lower rate of PJK than previously reported with other methods of fixation.Results: The range of the preoperative kyphosis was 62°–111°, and postoperative kyphosis was 12°–55°. There was one case of PJK (5.8%) and no cases of PJF.Conclusion: This study on short term outcomes of PSF using sublaminar bands in a hybrid technique for treatment of kyphosis demonstrated a lower rate of PJK than has been reported in prior studies. This technique protects the fixation within the upper instrumented vertebrae of long segment PSFs. %U https://www.ijssurgery.com/content/ijss/12/6/644.full.pdf
