Objective. To analyze long-term results of surgical correction kyphosis due to Scheuermann’s disease. Material and Methods. Design: retrospective cohort study. The study group included 43 patients (m/f ratio, 34/9). mean age was 19.1 (14–32) years; the postoperative follow-up 6 ± 10 (5–20) years. Two-stage surgery including discectomy interbody fusion followed by posterior conducted in 35 cases...

Study Design Biomechanical cadaveric study. Objective Clinical studies indicate that using less-rigid fixation techniques in place of the standard all-pedicle screw construct when correcting for scoliosis may reduce the incidence of proximal junctional kyphosis and improve patient outcomes. The purpose of this study is to investigate whether there is a biomechanical advantage to using supralami...

OBJECTIVE The aim of this study was to compare outcomes when the upper and lower thoracic regions were used as the site of proximal instrumentation to treat adult spinal deformity. METHODS MEDLINE, Embase and Cochrane library searches were performed to identify studies that compared outcome measures when the upper and lower thoracic vertebrae (UTV and LTV, respectively) were used as the site ...

Objective AIS is a three-dimensional (3-D) spinal deformity, characterized by lateral deviation, axial rotation and apical lordosis of three individual curves. The 3-D morphology of the different areas of the scoliotic spine has not been quantified so far. This is the first study to accurately define the 3-D morphology of AIS and compare it to normal anatomy. This is important for understanding...

Study Type Retrospective cohort study. Introduction Acute proximal junctional failure (APJF) was recently defined by the International Spine Study Group as: postoperative fracture of the upper instrumented vertebrae (UIV) or UIV + 1; UIV implant failure; proximal junctional kyphosis (PJK) increase > 15 degrees; or need for proximal extension of the fusion within 6 months of surgery.1 The incide...

STUDY DESIGN Retrospective cohort study. OBJECTIVE The S2-alar-iliac (S2AI) technique has been described as an alternative method for pelvic fixation in place of iliac screws (ISs) in spinal deformity surgery. The objective of this study was to analyze the impact of S2AI screws on radiographical outcomes, including spinopelvic parameters. METHODS A retrospective review of 17 patients receiv...
