An observational study in Spinal Fusion, Spondylolisthesis and Scoliosis, sponsored by Advanced Scanners Inc.. Terminated at 1 site in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-10-02.
Sponsored by Advanced Scanners Inc. · Observational
The primary objective is to assess the capability of the device as measured by its consistency, its accuracy, and feedback from surgical staff over the study period.
227 studies on the registry are indexed under Spondylolisthesis; 43 are open to participants now.
This study's enrollment of 1 is below the median of 108 across 79 observational studies indexed under Spondylolisthesis.

Counted across the registry records on this site, refreshed daily.
Subjects will be invited to participate from the Principal Investigator's clinic population. All subjects will be identified as requiring a spine surgery that meets the eligibility requirements.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

An optical 3D scanner used to register spine anatomy to surgical computer navigation systems.
Spine Registration
Closely match the Advanced Scanners optical scan of the partially exposed surface of the patient vertebra to the corresponding patient's preoperative MRI and/or CT scan, thereby learning the position of the rest of the vertebra. This endpoint includes registration of the relevant preoperative MRI or CT scan portion to the portion scanned by Advanced Scanners.
Time frame: Throughout the surgical procedure
Vertebral Shift Measurement
Use the intraoperative x-ray (typically O-arm) measurements taken at various times in the procedure to validate the capability of our scanner to determine relative shifts between vertebra as a function of time.
Time frame: Throughout the surgical procedure
Determination Of Bony Exposure Requirements
Measure the area of the exposed vertebra of registered adjacent segments. Bone regions will be identified in the scan mesh, segmented from the rest of the scan, and their areas determined directly from that surface region by integrating the area of the relevant mesh faces, in units of square millimeters or square centimeters.
Time frame: Throughout the surgical procedure
