A community-based, cross-sectional study that is part of the prospective Korean Health and Genome Study. ⋯ The prevalence of LBP is comparable between these Korean community residents and other population groups. Risk factors associated with LBP included advanced age, female sex, squatting, the presence of osteophytes, joint space narrowing, and advanced Kellgren-Lawrence grading on lumbar radiograph.

A single-center retrospective study. ⋯ Patients undergoing 1 level MIS TLIF for degenerative conditions can overall expect a short LOS postoperatively. Multiple preoperative, intraoperative, and immediate postoperative factors can prolong the LOS in this group. This information should help the surgical team in optimizing their intraoperative patient management.

The biomechanical effects of disc degeneration and hybrid fixation on the transition and adjacent segments were evaluated using a numerical approach. ⋯ The use of the hybrid fixator should involve a certain trade-off between the protection of the transition segment and the deterioration of the adjacent segments. This trade-off stiffness, which largely depends on both fixator design and disc degeneration, provides the improved rigidity and flexibility of the transition and adjacent segments.

Multicenter Study Comparative Study
Percutaneous lumbar pedicle screw placement aided by computer-assisted fluoroscopy-based navigation: perioperative results of a prospective, comparative, multicenter study.
Institutional review board-approved, prospective, multicenter, comparative study. ⋯ Use of Guidance reduces fluoroscopy and insertion times with increased accuracy compared with conventional fluoroscopic methods of percutaneous pedicle screw insertion.

Multicenter Study
Growing rods for the treatment of scoliosis in children with cerebral palsy: a critical assessment.
Retrospective analysis. ⋯ GRs via a posterior-only approach are effective. Constructs extending to the pelvis control PO more effectively. However, 30% of patients experienced deep wound infection.
