Kyphoplasty is one of the new methods of treating spinal fractures, which has been greatly developed in recent decades. In this article, we will first examine balloon kyphoplasty and then introduce kyphoplasty system (Trocar 3.1) of AJP brand.
What is kyphoplasty?
Kyphoplasty is a method to treat vertebral compression fracture. These fractures are one of the most common complications of osteoporosis. Osteoporosis leads to lose bone density and strength. As a result, bones become increasingly porous and vulnerable to fracture.
Vertebral body fracture leads to compression of the vertebra, shortening of the spine and deviation. This can lead to a kyphotic deformity and make it painful to stand or sit for long periods of time. It can also make it painful to move and walk.
These fractures can cause permanent spinal deformity and nerve damage if not treated quickly. For this reason, kyphoplasty is one of the most common techniques for the vertebral compression fractures treatment.
How is balloon kyphoplasty performed?
1- The patient needs to lie down on the stomach (Prone Position) and then the surgeon performs a local anesthesia.
2- The surgeon makes a small incision in the patient’s back to start the surgery.
3- The surgeon inserts a trocar into the vertebral body by passing through the skin and muscles of the patient’s back.
4- With the aid of a system called fluoroscopy (television radiography), the surgeon guides the trocar into the correct position.
5- The surgeon inserts a balloon through the trocar into the vertebra.
6- The balloon is then slowly and carefully inflated to create the necessary space for the bone cement. The balloon also helps the vertebra regain its normal shape and return to its normal height.
7- The surgeon then deflates the balloon and removes it from the vertebra.
8-The surgeon uses specially designed tools in the kyphoplasty system to fill the cavity with bone cement under low pressure.
9- After injection, the cement hardens quickly and stabilizes the bone.
10- Finally, the surgeon removes the trocar without the need for stitches.
Types of kyphoplasty
- Unipedicular balloon kyphoplasty
- Bipedicular balloon kyphoplasty
What are the benefits of using balloon kyphoplasty?
- Minimally invasive
- Opening the compressed space in the vertebra and spine, which reduces the pressure on the spinal cord and pain
- Restoration of height lost due to fracture
- Restoration of the normal alignment and structural integrity of the spinal column
- Improving the function of the spinal column
- Prevention of fracture growth and deformity of the spinal column
- Typically, the surgeon discharges the patients from the hospital the day after surgery.
- Most patients do not need strong painkillers 3-4 days after surgery.
- The patient can do daily activities after a short period of time after the operation.
General components of the kyphoplasty system
- Trocar for percutaneous entry and bone access
- Drilling tool
- Balloon and balloon inflator
- Bone cement and its delivery system (filler)
- Peripheral equipment including guide pin and introducer (cannula)

What is the difference between kyphoplasty and vertebroplasty?
Kyphoplasty and vertebroplasty are effective techniques for repairing damaged spine and reducing pain caused by compression fractures of the vertebrae. However, these are different from each other.
Vertebroplasty involves the injection of bone cement through the skin into the spongy bone of the vertebral body with the aim of reducing pain and preventing further reduction in the height of the vertebra.
In kyphoplasty, the surgeon uses a balloon to repair compression fractures and restore the shape of the vertebrae. The use of kyphoplasty reduces the pain caused by spinal fracture, stabilizes the bone, restores the lost height of the vertebra, and reduces kyphosis. In both methods, the use of visual guidance (usually fluoroscopy) is necessary.
Kyphoplasty or Vertebroplasty?
Some biomechanical studies demonstrate that kyphoplasty is initially superior for increasing and restoring body height of the vertebral and reducing kyphosis. Also, due to the use of balloon and creating enough space, the possibility of cement leakage is less in this method.
However, based on the studies, patients experience significant pain relief under each of these methods, and the rate of complications for both methods is low. Therefore, both kyphoplasty and vertebroplasty are safe and effective methods for vertebral compression fractures treatment.
What is bone cement?
Bone cements are biological materials that are obtained by mixing the powder phase and the liquid phase. These cements can be molded and implanted in the body as a paste. With the help of these cements, the surgeon can fill the bone cracks or gaps between the implant and the bone. The injectability of these cements has expanded their use as a minimally invasive surgical technique, and the surgeon widely uses in various orthopedic applications.
The characteristics required for bone cement include good biocompatibility, mechanical strength and sufficient hardness and radiopacity. Several options are available for use as cement or filler. Polymethyl methacrylate (PMMA) polymer has been used in orthopedic treatments for decades and is the most common material used as cement. Alternatives to PMMA with similar biomechanical properties include calcium sulfate and calcium phosphate cements.
Kyphoplasty risks
Kyphoplasty is a safe and effective surgical procedure. However, complications sometimes can occur after surgery. The most important of which are mentioned below:
- Infection
- Bleeding
- Problems caused by anesthesia
- Increased back pain
- Tingling, numbness, or weakness due to nerve or spinal cord injury
- Allergic reactions to chemicals used in bone cement
- Leakage of cement out of position, which can lead to compression of nerve elements or venous embolism.
Who needs the kyphoplasty system?
The surgeon recommends the kyphoplasty generally for people who suffer from chronic low back pain and poor mobility with compression fractures due to osteoporosis or pathological reasons such as bone marrow cancer, metastatic cancer, or benign vascular tumors.
The surgeon also uses this method in situations where the patient is so old that cannot tolerate open surgery or reconstructive surgeries of the vertebra. Therefore, to use the kyphoplasty set, the patient’s pain must be related to the fracture of the vertebra and should not be due to other problems such as disc herniation, arthritis or spinal canal stenosis.
In general, the surgeon uses the kyphoplasty in situations where simple treatments such as bed rest, use of a medical belt, physiotherapy, and painkillers have been ineffective. Conditions such as bone infection, spinal canal tumors, bleeding disorders, and sensitivity to drugs used during surgery also make the patient unsuitable for this treatment.
The doctor may perform a wide range of diagnostic tests such as blood tests, imaging (X-ray, CT and MRI) and bone densitometry scans to confirm the presence of a vertebral fracture and check other physical conditions of the person before surgery.
The best time to do the kyphoplasty for fracture
Kyphoplasty has the best results when it is performed shortly after the fracture. This procedure should be performed within 8 weeks after the occurrence of the fracture so that there is the greatest possibility of recovery.
Is kyphoplasty painful?
The patient may feel pain in the area where the trocar is placed. This pain should be resolved within a few days.
How effective is kyphoplasty system?
In kyphoplasty, the surgeon fills the pores created as a result of osteoporosis and caused bone fragility with cement injection. As a result, bone strength increases and the probability of re-fracture decreases. Kyphoplasty usually provides pain relief and improved mobility within 48 hours after surgery. In some cases, the patient may feel immediate pain relief.
Just a few weeks after surgery, two-thirds of patients are able to significantly reduce the dose of their pain medication. Many patients become asymptomatic, and about 75% of patients regain their lost mobility, which helps fight osteoporosis.
Warnings
- Sterilized with ethylene oxide gas
- A specialist surgeon must do surgery
- Use imaging device like fluoroscopy during surgery
- Maximum pressure for balloon equals to 400 psi or 27 bar or 27 atm. Exceeding the recommended pressure may cause balloon explosion.
