Summary
Adding a pedicular screw during spinal ligamentotaxis for fractured vertebrae significantly reduces bone fragment retropulsion and postoperative pain. This technique improves outcomes compared to standard methods.
Area of Science:
- Orthopedic Surgery
- Spinal Fusion Techniques
- Trauma Surgery
Background:
- Spinal ligamentotaxis is crucial for managing fractured vertebrae by reducing retropulsed bone fragments.
- Evaluating different ligamentotaxis techniques is essential for optimizing patient outcomes.
- Pedicular screw insertion is a potential adjunct to ligamentotaxis.
Purpose of the Study:
- To compare the efficacy and safety of two spinal ligamentotaxis techniques.
- To assess the impact of one pedicular screw insertion versus no screw in the index vertebra.
- To determine the effect on biomechanical values and complication rates.
Main Methods:
- A randomized clinical trial was conducted.
- The case group involved one pedicular screw insertion into the fractured vertebra.
- The control group did not receive a pedicular screw in the index vertebra.
Main Results:
- Postoperative retropulsion percentage and pain were significantly lower in the pedicular screw group (p=0.003 and p=0.004).
- Vertebral canal diameter, kyphotic deformity correction, and anterior height restoration were similar between groups.
- No significant differences in early or long-term postoperative complications were observed between the groups.
Conclusions:
- One additional pedicular screw insertion during ligamentotaxis improves retropulsion reduction and decreases postoperative pain.
- This technique offers enhanced clinical and imaging benefits for spinal fracture management.
- The findings support the use of an additional pedicular screw for improved spinal ligamentotaxis outcomes.
