Controlled laboratory study. ⋯ BPSs at the UIV led to greater motion at UIV+1 compared to bilateral TPH after cyclic loading. This is likely due to the increased rigidity of BPS compared to TPH leading to a "softer" transition between the TPH construct and native anatomy at the supra-adjacent level. Facet capsule compromise led to a 49.9% increase in UIV+1 motion, underscoring the importance of preserving the posterior ligamentous complex. Clinical studies that account for fusion rates are warranted to determine if constructs with a "soft transition" result in less proximal junctional kyphosis in vivo .

This is a retrospective radiographic study of a consecutive series of cases in patients with dropped head syndrome (DHS) at a single tertiary referral center. ⋯ The loss of compensation at the cervicothoracic junction was observed in all DHS types. B-DHS showed decompensation only at the cervicothoracic junction. N-DHS presented additional decompensation of the thoracic spine, and P-DHS showed decompensation between the thoracic and lumbar spine. Evaluation of global sagittal spinal balance is important for determining global spinal compensation associated with DHS and when considering treatment strategy.

A retrospective cohort study. ⋯ The administration of vancomycin suspended in fibrin glue was significantly associated with a lower likelihood of SSI in patients undergoing spinal instrumentation surgery.

Randomized Controlled Trial
Perioperative Nutritional Supplementation Decreases Wound Healing Complications Following Elective Lumbar Spine Surgery: A Randomized Controlled Trial.
The prevalence of malnutrition in patients undergoing lumbar spine surgery ranges from 5% to 50% and is associated with higher rates of surgical site infections, medical complications, longer lengths of stay, and mortality. ⋯ I.

Narrative review. ⋯ Advancements in our understanding of blunt TL trauma injuries have led to changes in management. Such advances are reflected in modern, dedicated classification systems. Over time, various key factors have been acknowledged and incorporated. In an effort to promote standardization of thought and language, past ideas and terminology should be retired.
