Interspinous process distraction device (implantable)
HCPCS code
Name of the Procedure:
Common Name: Interspinous Process Distraction Device Implantation
Medical Term: Interspinous Process Decompression (IPD)
Summary
This procedure involves the implantation of a small device between the spinous processes of the vertebrae in the lower back. It is designed to alleviate pain and treat certain conditions by stabilizing the spine and relieving pressure on spinal nerves.
Purpose
The procedure aims to treat conditions such as spinal stenosis by expanding the space around the spinal cord and nerves. The goal is to reduce pain, improve mobility, and reduce the need for more invasive spinal surgeries.
Indications
- Symptoms of lumbar spinal stenosis, including back pain, leg pain, and difficulty walking
- When conservative treatments (e.g., physical therapy, medications) have failed
- Patients who are not candidates for more invasive spinal surgeries due to health reasons
Preparation
- Patient will need to fast for a specific period before the procedure (typically 6-8 hours).
- Adjustments to medications may be required, particularly blood thinners.
- Diagnostic tests such as MRI or X-ray scans to assess the condition of the spine.
Procedure Description
- The patient is positioned and anesthetized (general or local anesthesia may be used).
- A small incision is made in the lower back.
- The surgeon gently separates the muscles to access the spine without cutting them.
- The interspinous process distraction device is inserted between the spinous processes of the vertebrae.
- The device is expanded to create space and relieve pressure on the spinal nerves.
- The incision is closed, and the area is bandaged.
Duration
The procedure typically takes about 45 minutes to 1 hour.
Setting
The procedure is usually performed in a hospital operating room or an outpatient surgical center.
Personnel
- Orthopedic or neurosurgeon
- Anesthesiologist
- Surgical nurses
- Possibly a physician assistant or surgical technician
Risks and Complications
- Infection at the surgical site
- Bleeding or hematoma
- Device migration or failure
- Nerve damage
- Allergic reaction to the materials in the implant
Benefits
- Significant reduction in back and leg pain
- Improved ability to walk and perform daily activities
- Minimally invasive compared to traditional spinal fusion surgery
- Shorter recovery time
Recovery
- Patients can often go home the same day or the day after the procedure.
- Instructions typically include limited physical activity and avoiding heavy lifting for several weeks.
- Follow-up appointments to monitor the healing process and the position of the device.
- Physical therapy may be recommended to improve strength and flexibility.
Alternatives
- Conservative treatments: physical therapy, pain medications, epidural steroid injections
- Traditional spinal fusion surgery, which is more invasive
- Laminectomy, a surgical procedure to remove part of the vertebrae
Patient Experience
During the procedure, the patient will be under anesthesia and will not feel pain. Post-procedure, there might be some discomfort and swelling at the incision site, but pain management options will be provided. Most patients experience a significant improvement in symptoms within a few weeks.
