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.

Solid aneurysmal bone cyst (S-ABC) is a variant of aneurysmal bone cyst (ABC), an uncommon benign bone tumor. There are few cases described in the cervical spine in kids up today. We treated a recurrent case with neurological involvement that needed multiple surgical procedures and radiotherapy. ⋯ At 6-year follow-up after four surgical procedures, sclerotherapy and radiotherapy, the aneurysmal bone cyst has been healed. Patient had neurological impairment after a local recurrence but had full recovered after final revision surgery.

The aim of this retrospective clinical study is to evaluate the effect of growing rod lengthening technique on sagittal balance in relationship with the spinopelvic parameters, in early onset scoliosis (EOS). ⋯ Significant improvement was found in the global thoracic kyphosis angle, by comparing the preoperative, the early postoperative and the last follow-up parameters statistically (p < 0.05). There was no statistically significant improvement in the spinopelvic parameters (p > 0.05). We claim that growing rod technique doesn't provide statistically significant improvement, in the sagittal spinal and the spinopelvic parameters, except for the kyphosis, in the treatment of EOS patients.

Sagittal spinopelvic alignment in 654 degenerative spondylolisthesis.
Degenerative spondylolisthesis (DS) is common degenerative spinal disease. Recent studies highlighted relationship between DS and high pelvic incidence (PI). Moreover, impact of spinopelvic alignment on clinical outcomes has been emphasized. We aimed at describing epidemiologic and sagittal spinopelvic parameters in patients with DS, comparing them with asymptomatic volunteers, and determining a classification of DS patients. ⋯ Predominance of high PI and female gender was emphasized in DS population. Moreover, these findings highlighted the importance of sagittal alignment analysis in DS with 24 % of patients with anterior malalignment and in the remaining 76 % (normal C7Tilt), more than 50 % had pelvic retroversion. Consequently, DS sagittal malalignment should lead to specific surgical correction adapted to each subgroup of patients.
