Percutaneous vertebroplasty

Percutaneous vertebroplasty is a minimally invasive surgical procedure used to treat vertebral compression fractures (VCFs), which are common in patients with osteoporosis, metastatic tumors, or traumatic injuries. The procedure involves the percutaneous (through the skin) injection of a special type of bone cement into the fractured vertebra to stabilize and strengthen it, thereby alleviating pain and restoring mobility.

Procedure

The process of percutaneous vertebroplasty is typically performed under local anesthesia and sedation, allowing the patient to remain awake but relaxed. Using fluoroscopy (a type of medical imaging that shows a continuous X-ray image on a monitor), the surgeon guides a needle through the skin and into the damaged vertebra. Once the needle is correctly positioned, a specially formulated acrylic bone cement is injected into the vertebral body. The cement quickly hardens, stabilizing the fracture and providing immediate pain relief in many cases.

Indications

Percutaneous vertebroplasty is primarily indicated for patients with painful vertebral compression fractures that have not responded to conventional treatment methods, such as rest, pain medication, or bracing. It is most commonly used in patients with osteoporosis-related fractures, but it can also be beneficial for treating vertebrae weakened by cancer or for certain types of spinal injuries.

Risks and Complications

As with any surgical procedure, percutaneous vertebroplasty carries certain risks. These may include infection, bleeding, increased back pain, and neurological symptoms if the cement leaks into surrounding areas. However, when performed by experienced practitioners, the procedure is generally considered safe and effective.

Benefits

The primary benefit of percutaneous vertebroplasty is pain relief, which can be significant and immediate for many patients. The procedure can also help restore vertebral height and spinal alignment in some cases, leading to improved mobility and quality of life.

Controversy

There has been some debate within the medical community regarding the effectiveness of percutaneous vertebroplasty. Some studies suggest that it provides significant pain relief and structural support, while others indicate that its benefits may be comparable to those of non-surgical treatments. Despite this, percutaneous vertebroplasty remains a valuable option for patients with severe and debilitating vertebral compression fractures.

Conclusion

Percutaneous vertebroplasty is a minimally invasive procedure that offers a potential solution for patients suffering from painful vertebral compression fractures. While it is not without risks, its ability to provide rapid pain relief and improve quality of life makes it an important tool in the treatment of certain spinal conditions.
