TL;DR: Higher BMI, preoperative disc degeneration at adjacent segment and intraoperative superior facet joint violation are risk factors for ASD and patients who are overweight or obesity should be fully informed of the risk of ASD.

TL;DR: Age at surgery >55 years, fusion to S1, T5–T12 >40°, low BMD and SVA difference >5 cm are risk factors for PJK, however, gender, combined anterior–posterior surgery, use of pedicle screw at top of construct, hybrid instrumentation and thoracoplasty are not associated with PJK.

TL;DR: The cement viscosity, injected cement volume, vertebral body wall incompetence, and a history of pulmonary diseases were the factors affecting the complications resulting from cement leakage in patients treated by percutaneous kyphoplasty.

TL;DR: This research provides a novel insight into the anti-apoptotic effect of 17β-estradiol on IL-1β-induced cytotoxicity, and may potentially lead to a better understanding of the clinical effects of 17 β-ESTradiol, especially in terms of intervertebral disc degeneration.

TL;DR: BMI>25 kg/m2, osteoporosis, obesity, and UIV at thoracolumbar junction are risk factors for the development and progression of PJK in DLS patients following long instrumented posterior spinal fusion.
