Cervical Area Thoracic Area MIS TLIF Patient Information

Anatomy of the Spine The spine is made up of vertebrae and is divided into 3 main sections: • Cervical (7 vertebrae) • Thoracic (12 vertebrae) • Lumbar (5 vertebrae) Below the lumbar spine is the sacrum which is comprised of 5 fused vertebrae. At the end of the spine is the coccyx, or the tailbone. The vertebrae bear the weight of the upper body and provide points of attachment for muscles and ligaments. It also protects the spinal canal and provides exit points for spinal nerves. The individual vertebrae are separated by intervertebral discs, which act as cushions or shock absorbers between...

General Conditions of the Lumbar Spine What is Degenerative Disc Disease? Degenerative changes in the spine may cause instability and pain in your back. Degenerative Disc Disease (DDD) involves the intervertebral disc and is part of the natural aging process. DDD can also result from torsional (twisting) injury to the lower back. Healthy Discs In the normal spine, your discs act as a cushion between vertebrae. Over time the discs can lose flexibility, elasticity, and height. When this happens, they lose their shock absorbing characteristics and can lead to abnormal motion or alignment of the...

What is Spondylolisthesis? Spondylolisthesis is a condition in which one of the vertebrae slips forward or backward. If left untreated, this can lead to deformity of the spine and narrowing of the spinal canal. Normal spine segment Displaced vertebra causing pressure on nerve Typical symptoms include low back pain, muscle spasms, thigh or leg pain, and weakness. Interestingly, some patients are asymptomatic and only learn of the disorder after spinal radiographs. MIS TLIF Patient Information

What is Lumbar Spinal Stenosis? Spinal stenosis is the narrowing of areas in the spine where nerve roots and the spinal cord must travel. It is most commonly caused by age-related spinal degeneration. This narrowing can put pressure on the nerves and cause pain. Healthy Spine Spinal cord Spinal Stenosis Spinal canal Exiting Nerve Root Compressed cord and nerves Vertebra Exiting Nerve Root Disc Symptoms often start gradually over time. Pain is likely to be present or worsen when you stand or walk, and lessen or disappear when you sit down or lean forward. Typically, people suffering from lumbar...

What Is a Minimally Invasive TLIF? Transforaminal Lumbar Interbody Fusion (TLIF) is a form of spine surgery in which the lumbar spine is approached through an incision in the back. Fusion is a means of stabilizing the spine by fusing two vertebrae together. The transforaminal approach accesses the disc through the space between the vertebrae. Minimally invasive surgery employs a strong understanding of anatomy combined with radiographic imaging to treat spinal conditions without undue injury to the surrounding soft tissues. The technique permits the surgeon to gently separate the muscles surrounding...

How Is a Minimally Invasive TLIF Performed? Spinal Access and Bone Removal First, the surgeon will make a small incision in the skin of the back over the vertebra(e) to be treated. Depending on the instrumentation used and the specific condition, the incision could be as small as 1 inch. In a traditional open TLIF, a 3 to 6 inch incision is typically required. A small section of the bone and disc are removed to clear a pathway for the interbody spacer. TLIF Spacer An interbody spacer is inserted into the disc space to aid in supporting areas between the vertebrae where the disc has been removed....

Pedicle Screws/Rods With the goal of Minimally Invasive Surgery in mind, preparations are made to insert pedicle screws and rods which are used to screw the spinal column in place while fusion occurs. The surgeon uses medical imaging to determine the precise screw location. The screws are then inserted into the vertebrae to be fused (as shown on page 8). Bone graft may be added along the side of the vertebrae to stimulate fusion. The surgeon will then close the incision and move the patient into recovery. What Should I Expect with My Recovery? A minimally invasive procedure typically allows patients...
