General population utility valuation study. ⋯ We provide a simple technique for converting the SOSGOQ2.0 to utilities. The ability to evaluate QALYs in metastatic spine disease will facilitate economic analysis and patient counseling. We also quantify the importance of individual SOSGOQ-8D items. Clinicians should heed these findings and offer treatments that maximize function in the most important items.Level of Evidence: 3.

Randomized Controlled Trial
The Efficacy of Intraoperative Freehand Erector Spinae Plane Block in Lumbar Spondylolisthesis: A Randomized Controlled Study.
Prospective randomized comparative (controlled) study. ⋯ Intraoperative ESPB as a part of multimodal analgesia was effective. For posterior instrumented patients with spondylolisthesis, it can relieve postoperative backache and reduce opioid consumption.Level of Evidence: 1.

Observational Study
Factors Affecting Pedicle Screw Insertional Torque in Spine Deformity Surgery.
Retrospective observational study of consecutive patients. ⋯ We propose the concept of an optimal S/P ratio for obtaining rigid pedicle screw fixation during spinal corrective surgery, which is different for patients with ASD and patients with AIS. The S/P ratio is useful for deciding the appropriate diameter screw for each case in preoperative planning.Level of Evidence: 4.

Retrospective case series. ⋯ Preoperative PROMIS PF and PI scores predicted improvement in postoperative PROMIS scores in lumbar spine surgery patients as worse preoperative scores correlated to improved PROMIS scores postoperatively. The calculated threshold t scores showed the ability to predict improvement in postoperative PROMIS scores. Preoperative PROMIS data may be useful in surgical decision-making and improved patient education regarding postoperative outcomes.Level of Evidence: 4.
