High sacral slope, lumbar lordosis, and sacral slope-to-pelvic incidence ratio are associated with new bone formation in ankylosing spondylitis.

Background/aim: Syndesmophyte formation appears to be site-specific in ankylosing spondylitis (AS) and new bone formation seems to occur in regions of microtrauma that are prone to tensile forces. Pelvic and spinal parameters are unique for each individual. Pelvic tilt and sacral slope are important anatomical features that compensate in harmony in keeping the sagittal balance.

Pelvic parameters as prognostic factors of radiographic progression in classical Ankylosing Spondylitis: A prospective follow-up data.

Radiographic progression in Ankylosing spondylitis (AS) is driven by mechanical strain. A well-balanced spine provides a favorable weight distribution across the entheses. Pelvic parameters are useful in assessing the shape of the spine.

Correlation of anterior chest wall anomalies and spinal deformities: a comprehensive descriptive study.

Purpose: To investigate the association and evaluate the characteristics between different types of anterior chest wall and spinal deformities.

Methods: A total of 548 patients with anterior chest wall deformities were included in this study. Clinical and radiological examinations were performed to determine spinal deformities.

Comparison of proximal junctional kyphosis rate according to fusion level.

Introduction: There are two main accepted reasons of Proximal junctional kyphosis (PJK) after Scheuermann's kyphosis treatment; overcorrection of initial curve and fusion that is too short proximally. The purpose of this study was to evaluate the incidence of PJK in patients who have been previously treated for Schuermann's kyphosis with a curve exceeding 70° and corrected under 40° according to proximal fusion level T2 or T3.

Methods: We retrospectively evaluated 30 patients treated for Schuermann's kyphosis with single stage posterior only procedure.

Do Magnetically Controlled Growing Rods Stimulate Longitudinal Vertebral Growth in Early-Onset Scoliosis Patients?

Objective: Distraction-based systems are the most common systems used in the treatment of early-onset scoliosis. In addition to its corrective and deformity progression preventive properties, its vertebral growth stimulation effect has been proved. Recently popularized magnetically controlled growing rods (MCGRs) showed superior results in terms of outcomes and decreased complication rate.
