Summary

This study looks at medical records of 3,500 adults who had a type of back surgery called ALIF between 2010 and 2020. The goal is to see if death rates from this surgery have gone down over the years and whether having a second surgery is riskier than the first. Researchers hope the findings will help doctors better prepare patients for repeat surgeries.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients \> 17 years of age, patients having had ALIF procedures as defined by CPT codes at participating Methodist facilities during 2010-2020 targeted. Exclusion Criteria: * Pediatric patients (as defined by age \<18 years old), pregnant women and incarcerated individuals. We do not anticipate any of these in an elective spine surgery group of patients. If they have emergency spine surgery it is normally not an ALIF.
