A case-control association study was conducted to investigate the genetic etiology for congenital scoliosis (CS) in a Chinese Han population. ⋯ This is the first report on SNPs of TBX6 gene in CS that suggests genetic variants of TBX6 gene is associated with CS and may play an important role in mediating susceptibility to developing CS in the Chinese Han population.

A study was performed using an axial loading device in healthy young subjects. ⋯ The compression device simulates the lumbar segmental alignment change from supine to standing posture in L1/2, L2/3, L3/4, and L4/5. However, in L5/S, axial loading using the DynaWell altered lumbar segmental alignment with a kyphotic change, while no significant difference was observed in this level between standing and supine positions. Awareness of these phenomena are essential for accurate interpretation of imaging results.

Cadaveric biomechanical study. ⋯ Augmentation improved the mechanical properties of the lumbar vertebral body for compression by a TDR implant.

A case report and review of previous literature are presented. ⋯ We reported a rare characteristic anomaly of the laminae of the axis with hypoplasia of the posterior arch of atlas. A multiplane reconstruction of the computed tomography images was very necessary for treatment of this case. Possible causes of this anomaly may be the failure of ossification or fusion of the embryological term, whereas invagination of the osteophyte may be associated with the traction of the dense fibrous band during growth and development. Surgical removal of the laminae could result in a satisfactory outcome.

Cross-sectional study of total sagittal spinal alignment in lumbar spinal canal stenosis (LCS) patients with and without intermittent claudication. ⋯ Patients of the Claudicant group exhibited forward bending of the trunk and pelvis backtilt, compared with those of the Nerve root group.
