Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 85 years
- All sexes
- No healthy volunteers
- Adult, Older adult
Study population: Patients > 17 years of age, patients having had ALIF procedures as defined by CPT codes at participating Methodist facilities during 2010-2020 targeted.
Who may be able to join
- Patients > 17 years of age, patients having had ALIF procedures as defined by CPT codes at participating Methodist facilities during 2010-2020 targeted.
Who cannot join
- 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.

About this study
To identify the current mortality rate for initial Anterior Lumbar Interbody Fusion(ALIF)procedures. Establish/prove mortality rates for this operation have dropped in the past decade.
Read the detailed description
Establish the mortality rate for "re-do" ALIF procedures [i.e., is it different than that of initial ALIF procedures and - if so - postulate that there are interventions that can be done in the pre-operative period to ameliorate that risk. This study is not designed to "prove" the latter hypothesis.]
This is a single sample study where medical records will be searched by Current Procedural Terminology(CPT) codes for ALIF codes (e.g. 22558, 22585, 22845, etc.) by trained researcher(s) at participating Methodist facilities going back 5-10 years to see if 1500-3500 cases can be identified within that time period.

Questions about this trial
What is this clinical trial studying?
An observational study of Lumbar Spondylolisthesis and Lumbar Spine Degeneration, run by Methodist Health System at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 20 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Establish/prove mortality rates (time frame: 5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05945550, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Mar 2026.
