Purpose: Wearing high heels is associated with chronic pain of the neck, lower back and knees. The mechanisms behind this have not been fully understood. The purpose of this study was to investigate the influence of high-heeled shoes on the sagittal balance of the spine and the whole body in non-habitual wearers of high heels.
Methods: Lateral standing whole body low-dose radiographs were obtained from 23 female participants (age 29 ± 6 years) with and without high heels and radiological parameters describing the sagittal balance were quantified. These were analyzed for differences between both conditions in the total sample and in subgroups.
Results: Standing in high heels was associated with an increased femoral obliquity angle [difference (Δ) 3.0° ± 1.7°, p < 0.0001], and increased knee (Δ 2.4° ± 2.9°, p = 0.0009) and ankle flexion (Δ 38.7° ± 3.4°, p < 0.0001). The differences in C7 and meatus vertical axis, cervical and lumbar lordosis, thoracic kyphosis, spino-sacral angle, pelvic tilt, sacral slope, and spinal tilt were not significant. Individuals adapting with less-than-average knee flexion responded to high heels by an additional increase in cervical lordosis (Δ 5.8° ± 10.7° vs. 1.8° ± 5.3°).
Conclusions: In all participants, wearing high heels led to increased flexion of the knees and to more ankle flexion. While some participants responded to high heels primarily through the lower extremities, others used increased cervical lordosis to adapt to the shift of the body's center of gravity. This could explain the different patterns of pain in the neck, lower back and knees seen in individuals wearing high heels frequently.

Background: Osteoporosis, a skeletal disorder affecting nearly 20% of the global population, poses a significant health concern, with osteoporotic vertebral body fractures (VBF) representing a common clinical manifestation. The impact of osteoporotic sintering fractures in the thoracolumbar spine on the sagittal lumbar profile is incompletely understood and may lead to the onset of clinical symptoms in previously asymptomatic patients.
Methods: This retrospective single-center study analyzed data from patients presenting with osteoporotic spine fractures between 2017 and 2022.

Background: Motion complexity is necessary for adapting to external changes, but little is known about trunk motion complexity during seated perturbation in individuals with spinal cord injury (SCI). We aimed to investigate changes following SCI in trunk segmental motion complexity across different perturbation directions and how they affect postural control ability in individuals with SCI.
Methods: A total of 17 individuals with SCI and 18 healthy controls participated in challenging sagittal-seated perturbations with hand protection.

Study Design: A retrospective study.
Purpose: This study aimed to compare the clinical effectiveness of en-bloc direct vertebrae rotation (DVR) to non-DVR for the correction of Lenke 5C.
Overview Of Literature: The primary goal of posterior correction is to preserve the lumbar spine and achieve a well-balanced spine.

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.

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.
