Summary
This modified vertebroplasty technique effectively reduces cement injection pressure and pain in patients with vertebral compression fractures. The method involves creating small voids, leading to improved outcomes and minimized complications.
Area of Science:
- Orthopedics
- Neurosurgery
- Radiology
Background:
- Vertebroplasty faces limitations due to high cement injection pressures.
- Kyphoplasty offers a solution by creating voids with balloon tamps.
- A novel modification aims to reduce cement delivery pressure in vertebroplasty.
Purpose of the Study:
- To present a modified vertebroplasty technique.
- To reduce cement injection pressure during vertebroplasty.
- To evaluate the safety and efficacy of the modified technique.
Main Methods:
- Modified vertebroplasty performed on 48 patients with acute vertebral compression fractures.
- Creation of small voids and micro-connections using a curved probe.
- Assessment of Visual Analogue Scale (VAS) pain scores preoperatively and postoperatively.
Main Results:
- Significant reduction in VAS pain scores at 1 week and 3 months postoperatively (p<0.001).
- No device-related complications reported.
- No major cement leakages causing neurological deficits or pulmonary complications.
Conclusions:
- Modified vertebroplasty with small cavity creation simplifies cement injection.
- The technique effectively minimizes cement leakage-related complications.
- This approach offers a safer and easier alternative for treating vertebral compression fractures.
