Getting an Interspinous Spacer

An interspinous spacer can be implanted through a small incision in your back, often using just local anaesthesia. The procedure can take anywhere from 45-90 minutes. The implant is designed to keep the space between your spinous processes open, so that when you stand upright, the nerves in your back will not be pinched or cause pain.

Detail - An Interspinous Spacer implanted in the spine

An interspinous spacer is placed between two bones, called spinous processes, in your lower back. The procedure to implant the spacer may be minimally invasive. When implanted, the spacer is not positioned close to nerves or the spinal cord, but rather behind the spinal cord, between the spinous processes.

The procedure is done in theatre at the hospital. With the help of x-ray guidance, the spacer is implanted through a small incision in your back. Depending upon your anatomy and specific medical conditions, your doctor may elect to use local or general anaesthesia.

The procedure to implant the interspinous spacer may last anywhere from 45 to 90 minutes. The procedure can be done under local or general anaethesia, depending on your medical health.
