Background: Understanding spinal sagittal balance is crucial for assessing and treating spinal deformities in pediatric populations.
Objective: The aim of the present observational study is to examine the parameters of sagittal alignment of the regional spine and spinopelvic region in asymptomatic pediatric populations and the characteristics of these parameters with age and sex.
Methods: We enrolled 217 participants, consisting of 112 males (51.6%) and 105 females (48.4%), aged between 4 and 15 years, with an average age of 12.19 years. Pelvic incidence, pelvic tilt, sacral slope, lumbar lordosis, thoracic kyphosis, T1 slope, C7 slope, cervical sagittal vertical axis, and C2-7 Cobb angle were measured. Three spine surgeons conducted radiographic measurements utilizing the PACS software. The measurement reliability was assessed through ICCs.
Results: Our results show significant age-related changes in pelvic tilt and cervical sagittal vertical axis, with notable gender differences in pelvic tilt, lumbar lordosis, and thoracic kyphosis. Girls have larger PT, boys have larger cSVA. PI, PT, and cSVA also differ among different age groups. Correlation analysis shows that a series of relationships that align with adult population patterns between pelvic incidence, pelvic tilt, sacral slope, lumbar lordosis, and thoracic kyphosis.
Conclusion: Significant variations in PT and cSVA across diverse age cohorts highlights notable disparities in the distribution of PT and cSVA values within the pediatric population. Gender-based differences in PT, LL, and TK and correlation in spinopelvic parameter could enhances our understanding of compensatory mechanisms.

High Preoperative T1 Slope is a Marker for Global Sagittal Malalignment.

Article Synopsis
- The study analyzed preoperative data from adult spinal deformity patients to establish a threshold for T1 slope (T1S) from cervical radiographs that indicates thoracolumbar malalignment.
- Researchers found a specific cutoff of 30 degrees for high T1S, with 50% of the patients falling above this threshold.
- Notably, higher T1S was linked with greater thoracic kyphosis, sagittal vertical axis, T1-pelvic angle, and pelvic tilt, suggesting that this measurement could serve as a useful parameter in cervical evaluations.
Kinematic limitations during stair ascent and descent in patients with adult spinal deformity.

Laboratory of Biomechanics and Medical Imaging, Faculty of Medicine, Saint Joseph University of Beirut, Beirut, Lebanon.
Background: Adults with spinal deformity (ASD) are known to have spinal malalignment, which can impact their quality of life and their autonomy in daily life activities. Among these tasks, ascending and descending stairs is a common activity of daily life that might be affected.
Research Question: What are the main kinematic alterations in ASD during stair ascent and descent?
Methods: 112 primary ASD patients and 34 controls filled HRQoL questionnaires and underwent biplanar X-from which spino-pelvic radiographic parameters were calculated.

Background: Proper positioning of a total hip arthroplasty (THA) plays a crucial role in the success and long-term survivorship of the implant. Cup positioning within the Lewinnek Safe Zone (LSZ) does not, however, avoid implant dislocation. Thus, the concept of a functional cup position has been introduced.

To analyze the influence of cervical range of motion on the preferable sagittal vertical axis in ankylosis spondylitis (AS)-related thoracolumbar kyphosis following single-level pedicle subtraction osteotomy (PSO). The clinical data of sixty-five AS patients who underwent single-level PSO from February 2012 to November 2018 in the Drum Tower Hospital of Nanjing University Medical School were retrospectively reviewed. Of the patients, 59 were males and 6 were females with a mean age of (34.

The aim of this study was to determine whether there is a compensatory lumbopelvic aspect associated with the two major acetabular phenotypes in dysplastic hips.
Methods: From September 2022 to March 2024, a total of 145 patients with symptomatic bilateral hip dysplasia were included in the study.
