This retrospective study included patients who underwent primary one-level minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) for degenerative lumbar spine conditions. ⋯ Level 3.

Retrospective cohort study. ⋯ Pre-frailty and frailty were associated with poor outcomes and higher level of care at discharge. Frail patients were less likely to undergo TL fusion, despite its association with improved survival. This suggests frailty should not discourage surgeons from performing thoracolumbar fusion. Frailty scoring upon admission may help guide management and set realistic expectations for patients and their families.

Retrospective single-center comparative analysis. ⋯ The predictive factors for LONDs include age, etiological diagnosis and SCSCS. We developed a nomogram model to predict LONDs, which could be useful for patient counseling and facilitating treatment-related decision-making.

Retrospective cohort study. ⋯ Cefazolin and vancomycin are comparable at preventing postoperative infections among patients with mild to moderate documented reactions to penicillin. Our findings also suggest that penicillin-allergic patients are not at higher risk of developing drug-related hypersensitivity reactions in response to cefazolin exposure when compared to those who received vancomycin.

Biomechanical Testing. ⋯ Surgical construct stiffness during a VCR is multifactorial. Larger rod diameter, increased number of fixation points, stiffer rod material, and increased number of rods across the resection site increase the construct stiffness. With minimal points of fixation using Co-Cr rods, increasing rod diameter does not impart greater construct stiffness unless additional fixation points are included.
