About the METRx® System
The METRx® System is designed for use in minimally invasive surgery and may be used in the cervical or lumbar spine.
The METRx® System consists of a series of dilators and tubes designed to be used during minimally invasive surgery.
Minimally invasive spine surgery is different from traditional, open spine surgery in that the open approach involves making a long incision down the back, stripping large bands of muscle away from the spine and then retracting, or pulling to each side, the surrounding muscles so the surgeon can get a clear view of the vertebrae of the spine to be treated.
Minimally invasive spine surgery requires a small incision, muscle dilation and the use of microsurgical and image guided technologies to access, view and repair spinal deterioration or damage. Muscle dilation involves gently and gradually separating, rather than cutting and stripping the muscles that surround the spine.
Surgeons can use the METRx® System to perform various surgical procedures including discectomy, cervical foraminotomy, and others.
To perform a minimally invasive procedure using the METRx® System, your surgeon will make a small (less than 1 inch) incision in the skin of your back over the vertebrae to be treated and then insert a series of progressively larger dilators, one around the other, to gradually separate the muscles and create a "tunnel" or portal through which the surgery may be performed.
Once the procedure is complete, your surgeon will remove the tube. The incision will be closed with a few stitches and covered with an adhesive bandage.

It is important that you discuss the potential risks, complications, and benefits of the METRx® System with your doctor prior to receiving treatment, and that you rely on your physician's judgment. Only your doctor can determine whether you are a suitable candidate for this treatment.
