Hypothesis
The Tadpole system® provides a safer and more effective alternative to traditional pedicle screw fixation for lumbar spinal fusion.
Conclusion
The Tadpole system® is a useful, easy-to-use, and safe spinal instrumentation technique for lumbar fusion surgery.
Supporting Evidence
- The mean operation time was 79 minutes, and the mean postoperative improvement rate of JOA score was 70.9 ± 24.8%.
- Instrumentation failure occurred in one patient, but no serious complications like nerve root injury or infection were reported.
- Bone union was confirmed in 29 of the 31 patients (93.5%) two years after the operation.
Takeaway
The Tadpole system helps fix the spine using hooks and rods, making surgery safer and easier for patients.
Methodology
The study involved a biomechanical analysis using human lumbar cadaveric spines and a clinical study with 31 patients undergoing spinal fusion.
Limitations
The study primarily focused on short-term outcomes and had a limited sample size.
Participant Demographics
31 patients (19 men and 12 women) with a mean age of 73.3 years.
