Interlaminar Spacer

interlaminar spacer

Interlaminar spacers are spinal implants, which facilitate a minimally invasive surgical option to treat certain types of spinal stenosis. For the right patients, our implant surgeons can relieve pain and symptoms from nerve compression caused by stenosis. The surgically implanted spacer is inserted between spinal segments to provide necessary space for nerves to function optimally without pain.


Patients diagnosed with central and foraminal spinal stenosis may benefit from placement of interlaminar spacers using a minimally invasive surgical approach. In some cases, a more invasive surgical treatment may be needed. Osteoarthritis and the aging process can lead to bone and soft tissue thickening with crowding and irritation of nerve tissue in the affected area of the spine.

A condition that causes back, arm or leg pain and/or “pins and needles” sensations, called neurogenic claudication, may decrease when the patient sits or bends the spine. This can temporarily provide the compressed nerves with more space and consequently relieves pressure. Affected individuals sometimes begin to walk in a bent-over manner. After proper treatment, like interlaminar spacer placement, patients may regain the ability to stand straighter and walk pain-free once again.

Our doctors at NJSO use a minimally invasive technique to insert the interlaminar space without the need for painful, open back surgery. This technique allows our patients to go home the very same day.

Same day surgery mean no hospital stay, which means less chance for infections, reduced overall cost and fewer problems.

When would this surgery be an option?

Surgery for spinal stenosis is only considered when one or more of these findings occur:

  • Your symptoms severely restrict your normal daily activities and have become unmanageable.
  • More conservative treatments do not relieve pain.
  • Nerve compression symptoms, like numbness or weakness, are worsening.
  • Your bladder or bowel control is decreasing.
  • You experience sudden changes in gait or become clumsy.

If severe osteoporosis is present or spinal anatomy prevents implantation, implant surgery will not be recommended. There are other possible contraindications which your physician will discuss with you. If you have cervical spinal stenosis, which affects the upper extremities and back, your doctor may recommend surgery (of another type) because this condition can cause nerve damage and paralysis. Most stenosis, however, occurs in the lower (lumbar) back.

Our personalized treatment approach

Our doctors are highly skilled at minimally invasive treatment methods to eliminate back pain once and for all. Patients receive a quick, outpatient experience without having to undergo multiple surgeries, resulting in a reduced recovery period.

Are you frustrated with the partial, temporary pain relief that you’ve gotten from side-effect laden medications or nerve block injections? An interlaminer spacer may be the right treatment for you.

This treatment is not advisable for every stenosis patient. Our doctors at NJSO work with each patient to evaluate your specific condition to create a tailored treatment plan thats right for you.

How does an interlaminar implantation work?

Placement of interlaminar spacer(s) is a minimally invasive alternative to more invasive laminectomy or laminectomy plus fusion surgery. When preforming a laminectomy, the orthopedic surgeon removes a portion of the lamina (the back part of the vertebra covering your spinal canal), thickened ligaments and any bone spurs in the spine. Tfhis allows the nerves to decompress.

During this alternative and minimally invasive approach, the surgeon places one or more titanium interlaminar spacers between the spinal bones and/or tissues. The spacer “props up” the bony structures, holding them in a flexed position, as if you were bending forward or sitting. The change in position takes place only in the region of the stenosis, limiting extension of the spine and maintaining a neutral or slightly flexed position.

Advantages to interlaminer spacers

For the right patient candidates, interlaminar spacers offer all the advantages that come with more invasive surgery, with benefits including:

  • May be performed under local anesthetic and considered lower risk.
  • Generally done on an outpatient basis.
  • Typically, there is no bone or tissue resection and incisions are smaller.
  • The spinal canal is not compromised.
  • Operating room time is shortened and may be less expensive for the patient.
  • Shorter recovery times and rapid symptom relief.
