Studies of adverse events (AEs) after orthopedic surgery commonly use composite AE outcomes. An example of such an outcome is any AE. These types of outcomes treat AEs with different clinical significance (eg, death, urinary tract infection) similarly. We conducted a study to address this shortcoming in research methodology by creating a single severity-weighted outcome that can be used to characterize the overall severity of a given patient's postoperative course. All orthopedic faculty members at 2 academic institutions were invited to complete a severity-weighting exercise in which AEs were assigned a percentage severity of death...

Intraoperative imaging is vital for accurate placement of instrumentation in spine surgery. However, the use of biplanar fluoroscopy and other intraoperative imaging modalities is associated with the risk of significant radiation exposure in the patient, surgeon, and surgical staff. Radiation exposure in the form of ionizing radiation can lead to cellular damage via the induction of DNA lesions and the production of reactive oxygen species. These effects often result in cell death or genomic instability, leading to various radiation-associated pathologies including an increased risk of malignancy...

Typical sources for graft material utilized in minimally invasive transforaminal lumbar interbody fusion include both autograft and allograft. Autograft is frequently utilized due to its theorized benefits in promoting fusion. During minimally invasive transforaminal lumbar interbody fusion, autograft is often obtained locally during the laminectomy and facetectomy. However, this locally obtained bone graft has exhibited questionable osteoconductive properties, often necessitating the addition of biologics to improve fusion rates...
