Sacral/Pelvic Fixation: New Tools and Techniques.

This review article explores the advancements in sacropelvic fixation, comparing traditional and modern techniques, with a focus on iliac and sacral 2 alar-iliac screw fixations. It addresses the biomechanical challenges inherent in securing the lumbosacral junction and discusses the integration of current and future technologies like robotics and augmented reality to improve surgical outcomes. The article underscores the importance of these innovations in enhancing stability and reducing complications in complex spinal surgeries.

Cervical Spine Research Society-Cervical Stiffness Disability Index (CSRS-CSDI): Validation of a Novel Scoring System Quantifying the Effect of Postarthrodesis Cervical Stiffness on Patient Quality of Life.

Study Design: Cross-sectional study.

Objective: The aim was to create and validate a novel patient-reported outcome measure (PROM) focusing on stiffness-related patient functional limitations after cervical spine fusion.

Summary Of Background Data: Cervical arthrodesis is a common treatment for myelopathy/radiculopathy, however, results in increased neck stiffness as a collateral outcome.

Complications in the Elderly Population Undergoing Spinal Deformity Surgery: A Systematic Review and Meta-Analysis.

Study Design: Systematic Review and Meta-Analysis.

Objectives: The elderly have an increased risk of perioperative complications for Adult Spinal Deformity (ASD) corrections. Stratification of these perioperative complications based on risk type and specific risk factors, however, remain unclear.

The lexicon of multirod constructs in adult spinal deformity: a concise description of when, why, and how.

The use of multirod constructs in the setting of adult spinal deformity (ASD) began to prevent rod fracture and pseudarthrosis near the site of pedicle subtraction osteotomies (PSOs) and 3-column osteotomies (3COs). However, there has been unclear and inconsistent nomenclature, both clinically and in the literature, for the various techniques of supplemental rod implantation. In this review the authors aim to provide the first succinct lexicon of multirod constructs available for the treatment of ASD, providing a universal nomenclature and definition for each type of supplementary rod.

The Intradiscal Osteotomy: An Alternative Technique for Adult Spinal Deformity Correction.

Adult spinal deformity (ASD) correction has changed considerably since the initial description of a Smith-Petersen osteotomy (SPO), including pedicle subtraction osteotomies (PSO), and more minimally invasive techniques. Here, we introduce and describe the intradiscal osteotomy (IDO), a novel variation of Schwab type 3 and 4 osteotomies allowing pedicle and vertebral body preservation, and its advantages and disadvantages. After pedicle screw placement, the posterior elements (except pedicles) are removed from the appropriate vertebrae, including the superior/inferior articulating processes, laminae, and spinous processes.
