Analysis of leakage causes in balloon assisted percutaneous balloon assisted percutaneous surgery

Patient, male, 80 years old, trauma induced T12 vertebral compression fractures were admitted to hospital, back pain, and no neurological symptoms. Ray - X: vertebral body compression of about 1/2, CT: vertebral canal without a bit, the posterior margin of the vertebral body without bone broken line, leading to

fracture line. Local anesthesia assisted balloon kyphoplasty. In the left side of the needle, the position of the pedicle was satisfactory. The lateral position was in the middle of the middle line, and the lateral position was 1/3 in the middle of the vertebral body. Injection of bone cement why appear strange phenomenon: bone cement to posterior filled, before the middle of the no, alarm!!! Continue to inject, is still - - - - -, and see a little leakage of the posterior margin of the vertebral body, stop injection, a moment before filling in the middle of the moment, but has not been filled too much! Fortunately, the patient had no symptoms of nerve. False alarm!!! I do not know how to return a responsibility, good puncture, intraoperative needle less than 8mm ah, manufacturers have not seen this kind of phenomenon, previously played 10 a few cases are first filled the front, after gradually after withdrawing the needle to the back filling, excessive will back edge leakage, were without neurological symptoms.

After Xray:1 to fill 2 back, before mid filling, intermediate is not continuous?!
There is a fracture line in front of the vertebral body, which is supposed to be the leading edge of the vertebral body:
1 bone cement coagulation time is too fast or the operation of the patients in the grasp of bone cement coagulation time deviation, but also the domestic cement would have this virtue.
2 column in the spine is still intact, but may be due to patients themselves belong to the more serious osteoporosis, although the appearance of a complete but can not be a bone broken line (CT), because of the increase in density, so bone cement rebound into the posterior margin of the vertebral body, so bad.
Is it related to surgical posture?
Disc compression on the upper end plate fractures, resulting in high pressure in the middle of the vertebral body, bone cement backward side leakage. If the full range of the spine can be extended to the full extent of the spinal column, it will not cause neurological symptoms, and reduce the compression of the disc to the end plate.
See the bone cement leakage as if it is from the front of the seepage, and may have a relationship with the injury itself, osteoporosis and the possibility of fracture line in front of.
However, the common leakage of bone cement in clinic is from Shii Shizu, epidural vein. Adjacent to the intervertebral space and surrounding soft tissue infiltration, the majority of imaging findings for the non neurological symptoms.
Leakage occurs, because of the pressure problem, simple bone cement in the diameter of the patients are not free of time will be squeezed out, so to solve this problem or in the expansion of the balloon.
It's a good use of PKP to prevent leakage! Why not? The balloon can be left in the vertebral body, which greatly reduces the occurrence of this situation!
Or equipment not! Domestic especially! This product is Israel's best, is your point......
