What is the METRx system?

What is the METRx system?

METRx® Micro Endoscopic. Discectomy System. The METRx® MED® System allows a surgeon access to the spine using a series of sequential muscle dilation tubes. This dilation approach offers less disruption to the surrounding muscles and also allows for the paraspinous muscles to remain attached to the spinous process.

What is METRx in spine surgery?

Minimally Invasive Microdiscetomy or METRx Discectomy uses microscopic or endoscopic techniques to access and remove this herniated disc and relieve pressure on the compressed nerves. Minimally invasive microdiscetomy or METRx discectomy is usually performed on an outpatient basis under spinal or general anesthesia.

How is minimally invasive spine surgery done?

Minimally invasive spine surgery may involve percutaneous (through the skin) or mini-open (small incision) procedures. Instead of cutting through soft tissues, segmental tubular retraction creates an expandable tunnel that passes between muscles to access the spinal column.

Is laminectomy the same as decompression?

Cervical laminectomy Laminectomy is surgery that creates space by removing the lamina — the back part of a vertebra that covers your spinal canal. Also known as decompression surgery, laminectomy enlarges your spinal canal to relieve pressure on the spinal cord or nerves.

How is a Microdiscectomy performed?

The surgeon uses small instruments to go under the nerve root and remove the fragments of disc material that have extruded out of the disc. The muscles are moved back into place. The surgical incision is closed and steri-strips are placed over the incision to help hold the skin in place to heal.

What is the difference between Microdiscectomy and laminectomy?

While microdiscectomy surgery is performed to remove the herniated intervertebral disc, laminectomy surgery is usually performed to increase the space of the neural foramen. The spinal cord runs from the lower part of the brain and ends around the lower border of the L1/L2 vertebrae.

What is the success rate of minimally invasive spine surgery?

Minimally Invasive Spine Surgery Success Rate An estimated 80 to 90 percent of our patients report less pain and better mobility after surgery. Over time, you will be able to resume some activities you once had to skip out on due to your spinal condition.

Who is a good candidate for minimally invasive spine surgery?

Patients with a herniated disc, spinal stenosis, and spondylolisthesis may be treated using a minimally-invasive approach when nonsurgical treatments fail to relieve symptoms for a period of three months or more. In many cases, elderly patients are good candidates for the procedure.

Is laminectomy a major surgery?

One concern you might develop is: Is a laminectomy a major surgery? The truth is, this surgery option is minimally invasive and, at most, might require a short hospital stay. Laminectomy offers you relief from the pain and neurological conditions that result from spinal stenosis.

Does bone grow back after laminectomy?

A laminectomy removes the entire lamina. Removal of the lamina allows more room for the nerves of the spine and reduces the irritation and inflammation of the spinal nerves. The lamina does not grow back. Instead, scar tissue grows over the bone, replacing the lamina, and protects the spinal nerves.

Is Microdiscectomy a major surgery?

Even though microdiscectomy recovery times are generally much faster than more invasive spinal surgeries, they’re still major procedures that involve general anesthetic. As such, they require careful oversight prior to medical personnel releasing you to return home.

How painful is Microdiscectomy surgery?

Compared with other surgeries, the pain a patient might experience from a microdiscectomy is mild to moderate. Pain from the surgery typically subsides within one to two weeks. Oftentimes, Tylenol can be used to manage the pain, however, sometimes a small Vicodin prescription is given to get through the first few days.

How long can a Microdiscectomy last?

While there is a risk for another herniation or a second surgery, the benefits of a successful microdiscectomy typically last for many years. One large study found that at an average follow-up of 4 years, about 84% of people who had the surgery rated their results as good or excellent.

How long does it take to recover from minimally invasive spine surgery?

Minimally invasive spinal stenosis surgery recovery time is typically brief, about six weeks for most patients.

How painful is minimally invasive spine surgery?

Because minimally invasive techniques do not disrupt muscles and soft tissues, it is believed that postoperative pain is less than pain after traditional open procedures.

How many years does a laminectomy last?

Success Rates of Lumbar Laminectomy for Spinal Stenosis Research suggests: 85% to 90% of lumbar central spinal stenosis patients find relief from leg pain after an open laminectomy surgery. 75% of patients may have satisfactory outcomes for up to 10 years postoperatively.

How long does it take to fully recover from a laminectomy?

Complete recovery may take 4 to 6 weeks or a few months after a lumbar laminectomy depending on the age and general health of the patient and the number of segments treated.

Can you live a normal life after Microdiscectomy?

Most patients will be able to resume all normal activities during this period, including physical therapy if ordered by your doctor. While few particularly enjoy this part of the recovery process, it’s vitally important for long-term stabilization. Physical therapy will increase your flexibility and muscle strength.

How painful is a Microdiscectomy?

Does a laminectomy weaken your spine?

A few potential complications of open lumbar laminectomy are: Neural tissue damage. Injury to the spinal cord’s dura, cauda equina syndrome, nerve roots, and the formation of scar tissue may occur causing neural tissue damage in the lumbar spine.
