Percutaneous vertebroplasty
1. The patient was placed in prone position and disinfected locally. Local anesthesia or general anesthesia were used as appropriate.
2. Puncture needle should be selected according to the need. The pedicle approach is usually used to puncture under fluoroscopy, and the core of puncture needle should be taken out after puncture is in place.
3. Inhale the prepared bone cement (PMMA) with a special syringe and install the screw propeller to fix it firmly.
4. Rotating the push rod of the screw propeller to observe the state of the extruded bone cement. When toothpaste is formed, the syringe is quickly connected to the needle and injected under fluoroscopy to observe the distribution of bone cement in the vertebral body.
5. After the injection, remove the screw propeller, insert the core of the puncture needle, pull out the puncture needle, bandage locally, and finish the operation.
Percutaneous kyphoplasty
1. Under fluoroscopy, the dismountable needle pedicle puncture needle enters the collapsed vertebral body through the pedicle. After confirmation, the needle seat is removed, the orthotic sleeve is inserted along the needle core, and then the needle core is taken out to establish a working channel.
2. Insert the vertebral drill into the orthopedic sleeve (if biopsy is needed, hollow vertebral drill can be used). Observe under fluoroscopy and remove the vertebral drill after reaching the required depth.
3. The balloon was put into the collapsed vertebral body and fluoroscopy confirmed that the balloon should all extend the
orthopedic sleeve (two marking rings of the head of the balloon can be seen).
4. The balloon was dilated by slowly injecting contrast agent under fluoroscopy with a pressure gauge (attached to the method of use). The collapsed vertebral body was elevated to form a cavity, the pressure and volume were measured, the contrast agent was sucked out, and the balloon was withdrawn slowly after retracting to vacuum.
4. Under fluoroscopy, cement was injected into the vertebral body, then the working cannula was pulled out and the operation was completed.
