A retrospective single-center study between January 2019 and January 2023. ⋯ The placement of a drain during anterior cervicotomy (anterior cervical discectomy and fusion/anterior cervical disc replacement) did not limit the occurrence of symptomatic postoperative hematoma.

Finite element analysis. ⋯ LSPS provided the greatest stability, while CBT provided the smallest amount of stability. However, the elevated stress on adjacent intervertebral disks and facet joints after LSPS fixation increased the possibility of adjacent segment degeneration. Cement-augmented pedicle screw fixation (CAPS) and combined cortical bone screw and pedicle screw fixation (CBT-PS) demonstrated significant biomechanical advantages in providing moderate fixation strength while reducing stress on the intervertebral disks and facet joints.

Retrospective case series. ⋯ In this series of 590 patients, conservative treatment yielded high bone union rates for pediatric LS. However, union rates decreased with stage advancement, especially in bilateral cases. These findings provide valuable insights for prognosticating natural history and outcome regarding LS treatment, bone union, and return to activity.

A retrospective cohort study. ⋯ 4.

Retrospective study. ⋯ Patients who sustain a fragility fracture prior to lumbar fusion have an increased risk of revision, pseudoarthrosis, and mechanical failure within eight years. Surgeons should be aware of this high-risk patient population and consider bone health screening and treatment to reduce these preventable complications.
