interspinous process spacer Overview:
An interspinous process spacer is a medical device that is implanted between the spinous processes of the vertebrae in the lower back. The spinous processes are bony protuberances that can be felt along the midline of the back, and they provide attachment points for the muscles and ligaments of the spine. The purpose of an interspinous process spacer is to create space between the vertebrae and reduce pressure on the spinal nerves, which can help to relieve pain and improve mobility in the lower back.
The spacer is typically made of a biocompatible material such as titanium or polyetheretherketone (PEEK) and is shaped like a small wedge. It is inserted through a small back incision and is held with screws or other fixation devices. The procedure to implant an interspinous process spacer is typically performed under general anesthesia and takes about an hour to complete.
Several different brands of interspinous process spacers are available on the market, and they are often used as an alternative to more invasive procedures such as laminectomy or fusion surgery. While the procedure is generally considered safe, some potential risks and complications can occur, including infection, bleeding, and damage to the surrounding nerves or tissues. As with any surgical procedure, it is important to carefully weigh the potential benefits and risks with a healthcare provider before deciding to undergo treatment
FAQ for Interspinous Process Spacer Implant:
What is the recovery time for interspinous spacers?
Most patients return to light daily activities within a few days to a few weeks after the procedure. Recovery depends on overall health, activity level, and the severity of spinal stenosis before treatment.
What is the success rate of interspinous spacers?
Interspinous spacer implants have shown strong success rates in reducing leg pain, numbness, and walking difficulty caused by lumbar spinal stenosis. Many patients report improved mobility and less pressure on spinal nerves.
What are the risks of interspinous spacers?
Possible risks include infection, bleeding, implant movement, nerve irritation, or ongoing back pain. Complications are uncommon when the procedure is performed by an experienced spine or pain management specialist.
Can L4 and L5 problems be cured permanently?
Treatment for L4-L5 spinal conditions focuses on long-term pain relief and improved function. While degeneration cannot always be reversed, procedures like interspinous spacers can help reduce nerve compression and improve quality of life.
Who is a candidate for interspinous spacers?
Patients with lumbar spinal stenosis, leg pain while walking, numbness, or lower back discomfort that improves when bending forward may be good candidates for an interspinous spacer implant after conservative treatments fail.
Pain treatments are covered by most major medical insurances including Medicare, Workers Comp, No Fault & Others.
