Spinopelvic changes based on the simplified SRS-Schwab adult spinal deformity classification: relationships with disability and health-related qualit…
2018
Study design Cross-sectional, observational study. Objective To study the occurrence of sagittal malalignment, the adaptability of a simplified sagittal modifiers grading of the Scoliosis Research Society (SRS)-Schwab adult spinal deformity (ASD) classification, and the deformity-specific SRS questionnaire version 30 (SRS-30) in an unselected adult cohort with symptomatic degenerative spinal disorders. Summary of background data The sagittal modifiers of the SRS-Schwab ASD classification correlate with health-related quality of life (HRQoL) measures in patients with ASD. The deformities and disabilities caused by sagittal malalignment in patients with common degenerative spinal disorders of…
Association of long-term outcome of long cervical fusion with sagittal balance: the significance of T1 slope minus cervical lordosis
2022
Introduction. Retrospective study to assess correlation between the sagittal alignment of the cervical spine and the long-term outcomes of long cervical fusion due to cervical spondylotic myelopathy (CSM), with the emphasis on T1 slope minus cervical lordosis (T1S-CL).Summary of background data. Growing evidence shows that the sagittal profile can play a major role in the outcomes of treatment, but the role of its correction is yet to be established. Material and methods. We conducted a retrospective analysis of 54 patients treated for CSM from 2006 to 2012. The neck pain-related disability was measured using NDI, the myelopathy was measured with the mJOA and Nurick scales. Six years after …
Sexual dimorphism in the vertebral wedging of the human lumbar vertebrae and its importance as a comparative framework for understanding the wedging …
2020
Lumbar lordosis is a key element of the upright posture, being interpreted as a consequence of bipedal locomotion. There is consensus that the generic modern human pattern of metameric vertebral body wedging is sexually dimorphic in modern humans. However, recently published studies have compared this pattern with other hominins, such as Neanderthals. These tried to establish whether the (male) Neanderthal lumbar vertebrae express a pattern that falls within or outside the range of modern human males. In the present study, data collected by 3D landmarks of the lumbar vertebrae of modern humans from different geographic regions and Neanderthals (Ntotal = 505 individual vertebrae) are used to…
Load Distribution in the Lumbar Spine During Modeled Compression Depends on Lordosis.
2021
Excessive or incorrect loading of lumbar spinal structures is commonly assumed as one of the factors to accelerate degenerative processes, which may lead to lower back pain. Accordingly, the mechanics of the spine under medical conditions, such as scoliosis or spondylolisthesis, is well-investigated. Treatments via both conventional therapy and surgical methods alike aim at restoring a “healthy” (or at least pain-free) load distribution. Yet, surprisingly little is known about the inter-subject variability of load bearings within a “healthy” lumbar spine. Hence, we utilized computer tomography data from 28 trauma-room patients, whose lumbar spines showed no visible sign of degeneration, to …
SAGITTAL ALIGNMENT OF SPINE REGULATED BY PELVIC INCIDENCE: A REVIEW
2012
The present paper is not only a review of the literature on pelvic incidence parameter, is also designed to reflect anew to the actions of preventive and compensatory physical activity, with particular reference to abdominal exercises. The incidence pelvic anatomy is a parameter whose value represents the angle between the perpendicular to the sacral plate at its midpoint and the line joining this point to the axis of the femoral head; it controls the spinal curves in accordance with the adaptability other parameters. The studies analyzed here suggest new considerations to be applied in the dynamic execution of preventive and compensatory physical activity. The training of the muscles lumba…
