The "Port-Hole" Technique for Spinal Stenosis

Spinal stenosis is the most common spine condition leading to surgery for patients over 60 years of age. Traditional surgery for spinal stenosis involves a procedure called a laminectomy where the back of the spine is removed over the area of stenosis. Unfortunately, this can cause the spine to become less stable and result in a worsening of the pain over time. In some cases, a complete laminectomy is not necessary to decompress the stenotic area.

In 1992, Dr. Kleeman designed an operation called the "Port-Hole" decompression. This technique maintains the stability of the spine by leaving the back of the spine intact. The areas of stenosis or narrowing are accessed through small windows or "port-holes". This allows for alleviating the compression without creating an unstable spine. Most patients are able to go home the morning after surgery.

A study was performed by the New Hampshire Spine Institute to evaluate this procedure. The results were presented at the annual meeting of the North American Spine Society in 1997 and received a national award for the outstanding poster presentation. Patients were polled four years after this surgery, with 97% of the patients reporting that their pain was improved and 100% being satisfied with the results of their surgery.
