Hypothesis
Can custom 3D-printed drill guides and titanium plates improve surgical outcomes in dogs with spinal instability due to congenital vertebral malformations?
Conclusion
The study found that custom 3D-printed drill guides and titanium plates can provide a safe and effective method for spinal stabilization in dogs.
Supporting Evidence
- Optimal screw placement was achieved in 63% of screws across the eleven dogs.
- Partial penetration of the medial wall was observed in 3% of screws.
- Partial penetration of the lateral wall was observed in 29% of screws.
- Full penetration of the lateral pedicle wall was observed in 5% of screws.
Takeaway
This study shows that using special 3D-printed tools can help fix dogs' spines better and safer.
Methodology
A retrospective analysis of 11 dogs who underwent spinal stabilization using custom 3D-printed plates and drill guides, with assessments of screw placement and neurological status pre- and post-surgery.
Limitations
The study's retrospective nature and small sample size limit the generalizability of the findings.
Participant Demographics
Eight of the eleven dogs were brachycephalic breeds, with a median age of 8.5 years and a median body weight of 10.5 kg.
