Minimally invasive stabilization surgery of osteoporotic fractures
The minimally invasive stabilization surgery of osteoporotic fractures can help to decrease or eliminate pain. An early and efficient treatment can reduce the usual after-effects of vertebral fractures as e.g. long-term bed rest or administration of analgetic. Furthermore, the vertebral height can surgically be restored.
In which cases a minimally invasive stabilization of the spine will be performed?
Not all kinds of vertebral fractures can be treated minimally invasively. In case of osteoporotic fractures of the vertebral end plate and vertebral fractures without affection of the dorsal margin a minimally invasive stabilization procedure can be considered.
What is the difference between a Kyphoplasty and a Vertebroplasty?
Vertebroplasty is a procedure where bone cement is injected into the vertebra to stabilize the fracture.
How is Vertebroplasty performed?
Through a small incision, the surgeon passes a cannula into the fractured vertebra. Thereafter, under x-ray guidance, bone cement is filled through the cannula into the bone.
How is Kyphoplasty performed?
Through a small incision, the surgeon passes a cannula into the fractured bone. Thereafter, a small balloon is inserted into the fractured vertebral body. Typically, the surgeon places one balloon on each side of the vertebral body in order to better support and stabilize the bone. Once inserted in the fractured bone, the balloons are carefully inflated to gently raise the collapsed bone into normal position.
The inflated balloons create a cavity within the vertebra and compact the soft, inner bone against the outer wall.

What are the results of the minimally invasive stabilization of the spine?
The results of minimally invasive stabilization show a considerable relief of pain after surgery. But osteoporosis, the primary cause of spinal fractures, cannot be cured, so fractures of the adjacent vertebral bodies are possible. These fractures will have to be treated the same way.
What is the after-care of a minimally invasive stabilization surgery?
Typically, you will be able to walk without brace the day after surgery. You will have to schedule follow-up visits where x-rays will be taken to see if your recovery is successful. Furthermore, a medical treatment of the osteoporosis is necessary.
