Accuracy Of A Sacral Drilling With A Custom 3d Printed Drilling Guide Or Free-Hand Technique In Canine Experimental Sacroiliac Luxation, Daniel Mccarthy
LSU Master's Theses
ABSTRACT
The objective of this study was to improve the accuracy of drilling during the repair of sacroiliac luxation with a 3D-printed patient-specific drill guide (3D-GDT) compared to free-hand drilling technique (FHDT). A blinded, randomized, prospective study was performed including sixteen canine cadavers (20-25 kg) euthanized for reasons not related to the study. Dorsal, bilateral, sacroiliac luxations (SILs) were created experimentally. A pelvic CT was performed pre- and post-drilling. The FHDT was drilled followed by 3D-GDT for each sacrum. CT and 3D measurements of craniocaudal and dorsoventral angles were compared between FHDT and 3D-GDT, as well as deviations of entry …
