TLDR
The use of the S2AI technique over the IS technique was an independent predictor of preventing reoperation and SSI, while achieving similar clinical and functional outcomes.Abstract:
Study design Retrospective comparative study. Objective To compare clinical and radiographic outcomes between the S2-alar-iliac (S2AI) and the iliac screw (IS) techniques in the adult population and clarify the clinical strength of S2AI screws. Summary of background data S2AI screws have been described as an alternative method for lumbosacropelvic fixation in place of ISs. The S2AI technique has several advantages with lower prominence, increased ability to directly connect to proximal instrumentation, less extensive dissection of tissue, and enhanced biomechanical strength over the IS technique. However, the clinical significance of these advantages remains unclear. Methods A single-center retrospective review of patients who underwent lumbosacropelvic fixation yielded 25 IS group patients and 65 S2AI group patients. Baseline demographic information, postoperative complications, pain and functional outcomes, and screw-related outcomes were collected. Results The S2AI group had lower rates of reoperation (8.8% vs. 48.0%, P Conclusion The use of the S2AI technique over the IS technique was an independent predictor of preventing reoperation and SSI, while achieving similar clinical and functional outcomes.

TL;DR: The use of the S2AI screw technique resulted in a reduced rate of symptomatic screw prominence, and MDSS ≤23 mm was the strongest predictor of sympt automatic pelvic screw prominence.

TL;DR: Compared with the IS technique, the S2AI technique demonstrated a lower rate of overall re operation, a similar rate of PJK, longer time to reoperation, and possible reduction in PI.

TL;DR: In this large, single-center series of adult patients, iliac screws were an effective method of spinopelvic fixation that had high rates of lumbosacral fusion and far lower complication rates than previously reported.

Investigation of the freely available easy-to-use software 'EZR' for medical statistics.
TL;DR: EZR enables the application of statistical functions that are frequently used in clinical studies, such as survival analyses, including competing risk analyses and the use of time-dependent covariates, receiver operating characteristics analyses, meta-analyses, sample size calculation and so on, by point-and-click access.

Outcome and complications of long fusions to the sacrum in adult spine deformity: luque-galveston, combined iliac and sacral screws, and sacral fixation.
TL;DR: According to the current findings, the Luque-Galveston fixation technique has an unacceptably high rate of pseudarthrosis, and this method is not recommended for adult deformities.

TL;DR: For high-grade spondylolisthesis and long adult deformity fusions to the sacrum, a montage of bilateral S1 screws and iliac screws were effective in protecting the sacral screws from failure.

TL;DR: A meta-analysis showed that the thigh thrust test, the compression test, and 3 or more positive stressing tests have discriminative power for diagnosing SI joint pain.

Low profile pelvic fixation: anatomic parameters for sacral alar-iliac fixation versus traditional iliac fixation.
TL;DR: Iliac fixation through the S2 ala provides a reproducibly chosen starting point in line with S1 pedicle anchors and is less likely to be affected in cases using iliac crest bone graft harvest because of the more anterior position of the anchor in the ilium.
