This study aimed at investigating the effects of different body positions and axial loads on spinal stiffness to better understand spinal stabilisation mechanisms. ⋯ This study showed that spinal lumbar and thoracic stiffness increases when body position is changed from prone to standing. Additional axial load of 50% of the subject's body weight results in reduced spinal stiffness during standing. These slides can be retrieved under Electronic Supplementary Material.

Existing automated spine alignment is based on original X-rays that are not applicable for teleradiology for spinal deformities patients. We aim to provide a novel automated vertebral segmentation method enabling accurate sagittal alignment detection, with no restrictions imposed by image quality or pathology type. ⋯ This is the first study using fine-tuned Mask R-CNN to predict vertebral locations on optical images of X-rays accurately and automatically. We provide a novel alignment detection method that has a significant application on teleradiology aiding out-of-hospital consultations.

To investigate the relationship between relative location of the sacral base and spinal alignment in standing healthy adult volunteers. ⋯ The center of the sacral base is normally located 3.8 ± 0.8 cm caudal to the cranial vertex of the iliac crest. The sacral base was located more caudally in men than in women, regardless of age. The more caudal the sacral base, the angle of the spino-pelvic parameters (TK, LL, PI, SS) progressively increases along with a decrease in the sacro-acetabular distance (Pth). Pelvic tilt did not correlate with the location of the sacrum.

Associated factors for and the natural course of sacroiliac (SI) joint degeneration in the normal population are unknown. The purpose of this study was to determine associated factors for and the progression rate of SI joint degeneration. ⋯ We found substantial SI joint degeneration in 12.7% of healthy middle-aged subjects and considered it to be part of the normal aging process. There may be individual factors associated with its occurrence. These slides can be retrieved under Electronic Supplementary Material.
