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.
