What is causing my pain?

There are several primary causes of lumbar spine problems. The majority of symptoms are caused by disc, bone, or ligaments pressing onto the nerve roots or spinal cord.

Degenerative Disc Disease (DDD)

During the natural aging process, the discs between each vertebral body can lose their flexibility, height, or elasticity which can cause discs to herniate, bulge, or leak their gelatinous core.

Spondylolisthesis

Spondylolisthesis is a condition where your vertebrae have moved forward or backward. This can lead to a narrowing of the spinal canal, causing pressure on your nerves if left untreated.

Spinal Stenosis

Spinal stenosis is the narrowing of the cavity where your spinal cord passes through. The common cause for this is spinal degeneration through age. If untreated, this pressure on your nerves can cause numbness or pain.

Symptoms

Conditions in which one of the vertebrae slips forward or backward can lead to degeneration and narrowing of the spinal canal.

Typical symptoms include:

  • Lower back pain
  • Muscle spasms
  • Numbness
  • Burning 
  • Thigh or leg pain
  • Weakness
  • Tingling

What are my treatment options?

Many symptoms can be treated through methods that involve:

  • Pain mangement
  • Rest and/or activity modification
  • Physical therapy
  • Steroid injections

Your physician may suggest spinal surgery if you do not gain relief from non-operative forms of treatment and/or if your symptoms are increasing or worsening.

What is T/PLIF?

Transforminal or Posterior Lumbar Interbody Fusion (T/PLIF) is a procedure used to treat problems associated with DDD such as spine instability and deformities.

In this procedure, the surgeon works on the spine from the back (posterior) and removes a spinal disc in the lumbar spine. An interbody fusion implants with bone graft are inserted into the space between the two vertebrae where the disc was removed and supporting fixation is added (screws, plates, etc.).

The goal of the procedure is to stimulate the vertebrae to grow together into one solid bone, a process known as fusion. Fusion creates a rigid and immovable column of bone in the problem section of the spine.

Possible benefits include:

  • Pain relief
  • Stability
  • Return to activities

What is the dualX®Slim expandable interbody implant?

The dualXSlim expandable interbody implant is designed to help restore the natural spacing and alignment of the spine. After it is placed, the implant expands in both height and width to create a larger area of support between the bones of the spine.

This unique design helps provide stability, supports new bone growth for fusion, and allows surgeons to use less invasive surgical approaches that may help reduce the impact of surgery and support recovery.

Is a T/PLIF right for me?

Your spine surgeon might determine that a T/PLIF procedure is a good option if you:

  • Are skeletally mature with Degenerative Disc Disease (DDD) at one or more contiguous levels from L2–S1
  • Have up to Grade I spondylolisthesis or retrolisthesis at the involved level(s)
  • Received 3–6 months of non-operative treatment

What to Expect: Minimally Invasive Surgery

Before

  1. Your physician will evaluate your condition and consider all treatment options.

  2. If surgery is the best option, your spine surgeon will discuss complications, risks, pre-operative, and post-operative procedures.

  3. Once admitted to the hospital, you will be taken to a pre-op room and prepared for surgery (put to sleep, etc.).

During

  1. An x-ray is taken of your spine to identify the location of the operative disc space.

  2. Through a small incision, the lumbar spine will be accessible from your back.

  3. Disc removal will take place followed by insertion of an interbody fusion implants packed with bone graft.

  4. Pedicle screws and rods are inserted into the vertebral body to stabilize the spine and implants while fusion occurs.

  5. Your surgeon closes the incision and moves you into recovery.

After

  1. Your physician will determine post-operative procedures and safety guidelines to follow at home.

Adverse Events & Risks

All surgeries present risks and complications that are important to discuss with your physician prior to your surgery. Listening to your physician’s guidance both before and after surgery will help ensure the best possible outcome from your procedure.

Specific complications associated with the spinal implant procedure include, but are not limited to:

  • Failure to fuse (Pseudoarthrodesis)
  • Interbody device or hardware malfunctions
  • Damage to the spinal cord nerve roots, or nerves, possibly resulting in paralysis or pain

Please contact your physician to discuss all potential risks.
