The purpose of the present paper is (1) to describe the occupational distribution of persons with incident back disorders and (2) to determine the incidence rate ratio (RR) for back pain amongst patients working in specific occupation groups. ⋯ This study is the first to investigate the occupational status and RR of back disorder incidence across occupation groups in Denmark. The distribution of back pain disorder incidents in the cross-sectional study is weighted to occupation groups involving hard physical activity. This evidence may be useful for considering work environment or pension reforms. These slides can be retrieved under Electronic Supplementary Material.

To evaluate the 3D deformity of the acetabula and lower limbs in subjects with adolescent idiopathic scoliosis (AIS) and their relationship with spino-pelvic alignment. ⋯ Subjects with AIS had a more abducted acetabulum at the lowered side, more anteverted acetabulum and a lack of anterior coverage of both acetabula. These alterations were strongly related to pelvic tilt.

Fusing shorter than the last touched vertebra (LTV) is a safe approach in flexible main thoracic (MT) adolescent idiopathic scoliosis (AIS) curves. ⋯ Proximal fusion carries the risk of adding-on, but leaving unfused segments in the lower spine increases the potential for compensatory mechanisms to improve spinal and truncal balance. In mature patients with a flexible MT curve, surgeons may consider fusion at or cranial to the LTV.
