Name of the Procedure:
Percutaneous Vertebral Augmentation, also known as Kyphoplasty.
Summary
Percutaneous vertebral augmentation (PVA) is a minimally invasive procedure designed to stabilize and reinforce fractured vertebrae. It involves creating a cavity in the fractured vertebra using a mechanical device and then injecting bone cement to stabilize the bone. Imaging guidance ensures precise placement of tools and materials.
Purpose
PVA is primarily performed to treat:
- Painful vertebral compression fractures (VCFs) often caused by osteoporosis, spinal tumors, or trauma. The goals are to:
- Reduce pain.
- Stabilize the vertebra.
- Restore some of the lost vertebral height.
- Improve mobility and quality of life.
Indications
- Severe back pain caused by vertebral compression fractures.
- Osteoporotic fractures.
- Fractures due to metastatic bone disease.
- Ineffectiveness of conservative treatments (e.g., pain medications, rest).
- Loss of height or spinal deformity due to fractures.
Preparation
- Patients may need to fast for several hours before the procedure.
- Medication adjustments, especially blood thinners, might be necessary.
- Pre-procedure imaging, such as MRI or CT scans, to assess the exact location and condition of the vertebrae.
Procedure Description
- Anesthesia: The patient receives local anesthesia, possibly with mild sedation.
- Positioning and Imaging: The patient is positioned face down, and imaging guidance (fluoroscopy or CT) is used to locate the fractured vertebra.
- Cavity Creation: A small incision is made, and a needle (trocar) is inserted into the vertebral body.
- Mechanical Device: A balloon catheter is inserted through the needle and inflated to create a cavity and restore vertebral height.
- Bone Cement Injection: The balloon is removed, and bone cement is injected into the cavity to stabilize the fracture.
- Completion: The cement hardens, the tools are removed, and the incision is closed.
Duration
The procedure typically lasts about 1 to 2 hours.
Setting
PVA is performed in a hospital operating room or an outpatient surgical center.
Personnel
- Interventional radiologist, orthopedic surgeon, or neurosurgeon.
- Nursing staff.
- Anesthesiologist or nurse anesthetist (if sedation is used).
Risks and Complications
- Infection.
- Bleeding.
- Cement leakage, potentially leading to nerve damage or embolism.
- Allergic reaction to anesthesia or materials used.
- Rarely, worsening of pain or new fracture at other spinal levels.
Benefits
- Rapid and significant pain relief.
- Stabilization of the fractured vertebra.
- Improved mobility and quality of life. Benefits are often realized within a few days to a week post-procedure.
Recovery
- Patients typically remain under observation for a few hours post-procedure.
- Most can go home the same day or the day after.
- Mild soreness at the incision site is common.
- Avoid heavy lifting and strenuous activity for a few weeks.
- Follow-up appointments to monitor recovery and evaluate the success of the procedure.
Alternatives
- Conservative treatments (pain medication, bracing, physical therapy).
- Vertebroplasty (similar to PVA but without balloon cavity creation).
- Open surgical interventions (more invasive with longer recovery).
## Pros and Cons:
- PVA offers quicker pain relief and shorter recovery time compared to conservative treatments and surgery.
- Vertebroplasty is less complex but might not restore vertebral height as effectively.
Patient Experience
- During the procedure, the patient might feel pressure but should not experience pain due to anesthesia.
- Post-procedure soreness is typical at the incision site but resolves within a few days.
- Pain management includes over-the-counter or prescription pain medications as needed.
- Patients often experience significant pain relief and improved mobility shortly after the procedure.
