The objective was to assess the effects of therapeutic nuclear magnetic resonance (tNMR) as a conservative treatment for lumbar radicular syndrome (LRS) in patients with lumbar disc herniation. ⋯ This trial was the first to investigate the effects of tNMR as an additional treatment of lumbar disc herniation with LRS. The application of tNMR did not meet MCID criteria. It rendered few statistically significant differences between patient groups. The overall results of this trial make a clinical implementation of tNMR in the treatment of lumbar disc herniation with LRS appear premature. Further research is needed to better understand the mode of action of tNMR on compressed neural tissue and to elucidate the issue of the cost/benefit ratio.

The interaction between the sagittal alignment of the spine and pelvis and the compensatory mechanism in patients suffering from spinal disorders has been well documented. However, in patients with hip osteoarthritis (HOA), few studies have explored how the hip joint pathology could affect the sagittal alignment of the hip, pelvis and spine, and no reports have investigated whether these changes are involved in the pathogenesis of low back pain in these patients. The aims of this case-control study were to investigate the sagittal spine-pelvis-leg alignment in patients suffering from severe HOA and to understand whether the alignment was related to the occurrence of low back pain and the health-related quality of life in these patients. ⋯ The sagittal morphology of the pelvis in patients with severe HOA was normal and might not be involved in the development and progression of this disorder. Although the whole spine was involved in compensating for the flexed hip joint, the poor ability resulted in severely unbalanced spinal-pelvic alignment in these patients. The forward inclined spine and retroverted femur would contribute to the poor physical activities in these patients. However, the abnormal sagittal spine-pelvis-leg alignment in patients with severe HOA might not be involved in the pathogenesis of low back pain.

Despite the high prevalence of low back pain during pregnancy there is still a lack in the understanding of its aetiology. Changes of the spinal posture due to the anatomical changes of the pregnant body seem to be in part responsible for the back pain. In this pilot study we assessed the potential to accurately measure the spinal posture and pelvic position during pregnancy without any harmful radiation using a spine and surface topography system. ⋯ The results of our study show that pregnancy has an effect on the spinal posture, and that spine and surface topography can be used to measure these changes three-dimensionally and without any harmful radiation. In future studies this technique could allow to further evaluate the relationship between posture and low back pain during pregnancy, helping to understand the aetiology of low back pain in pregnancy as well as to identify methods for its prevention and treatment.

Comparative Study
Pelvic incidence and pelvic tilt measurements using femoral heads or acetabular domes to identify centers of the hips: comparison of two methods.
The aim of the study was to compare pelvic incidence (PI) and pelvic tilt (PT) measurements using the bicoxofemoral axis obtained from either femoral heads or acetabular domes on lateral digital radiographs of the spine. ⋯ We suggest that either the femoral heads or the acetabular domes may be used for reliable PI and PT measurements on the lateral standing long-cassette digital radiographs of the spine.

To explore the relationship between cervical spine and the global spine alignment and to postulate the hypotheses that a lordotic alignment of cervical spine is not the only standard to identify asymptomatic subjects, and the degenerative modification of cervical curves depends primarily on their spinal-pelvic alignment. ⋯ The cervical alignment correlates with their global spine and pelvic curves. And lordosis is not the only presentation in asymptomatic subjects. The degenerative modification of cervical disc angles was the compensation of global spine degeneration for horizontal gaze. Cervical angles are influenced by their TK angles, occipital-C2 joint and the tilt of T1 vertebral body. The occipital-C2 joint has a compensating mechanism in all Roussouly types in cervical spondylosis.
