MINIMALLY INVASIVE POSTERIOR FIXATION PATIENT INFORMATION LEAFLET

INTRODUCTION The lumbar spine is made up of five bones called vertebrae. The bones and joints contain and protect the spinal cord, while also allowing motion such as bending and twisting. The main joint between two vertebrae is called a disc. Each disc is comprised of two parts, a tough and fibrous outer layer (annulus fibrosus), and a soft, gelatinous centre (nucleus pulposus). These two parts play a vital role in allowing and restricting motion.

WHAT IS CAUSING MY PAIN? Age, genetics, injury, and everyday wear and tear caused by routine activities can contribute to damage and deterioration of the discs in your lower back. Your surgeon may have diagnosed a herniated disc, disc degeneration, spinal stenosis, or loss of disc height as compared to your other discs. Symptoms of these conditions can include loss of motor function and dexterity, tingling or numbness in the lower extremities, radiating pain, and weakness and/or numbness in your legs.

WHAT IS A MINIMALLY INVASIVE POSTERIOR FIXATION? Posterior Fixation for the lumbar spine is a surgical procedure that helps relieve pressure on the nerve roots and/or spinal cord to provide realignment, immobilisation, and stabilisation of spinal segments in skeletally mature patients. Compared to a traditional open procedure, the minimally invasive approach is performed through a minimal incision in your back, and the back muscles surrounding your spine are gently separated, rather than cutting through them. Decompression may be necessary if the symptoms are caused by a compression of the spinal...

NewPort™ Posterior Fixation IS MINIMALLY INVASIVE POSTERIOR FIXATION THE RIGHT PROCEDURE FOR ME? Your surgeon may have suggested that you are a candidate for a Minimally Invasive Posterior Fixation procedure. NewPort is intended to provide stability of the spine and is indicated for skeletally mature patients with Degenerative Disc Disease (DDD). DEGENERATIVE DISC DISEASE (DDD) During the natural aging process, the disc between each vertebral body can lose its flexibility, height, and elasticity which can cause a tear in the tough outer layer of the disc, causing the disc to herniate, bulge,...

PREPARING FOR SURGERY Your surgeon will provide a clinical examination and may conduct some diagnostic tests to ensure you are a candidate for the procedure. These may include MRI, CT scans, and/or X-rays. Your surgeon may provide you with guidance on what to do or not do before your procedure. It is important that you follow your surgeon’s recommendations in preparation of your surgical procedure.

WHAT TO EXPECT DURING SURGERY DURING SURGERY After you are sedated, positioned face down, and surrounded by the appropriate surgical draping, an X-ray image is taken of your spine to identify the location of the operative disc space. STEP 1: APPROACH Your surgeon will make a small incision down your back. The size of the incision can vary based on the number of levels and/or complexity of your case. STEP 2: DECOMPRESSION Your surgeon may decide that decompression of the affected vertebrae and discs may be necessary to reduce pressure from the cord or symptomatic nerve root. During decompression,...

WHAT TO EXPECT AFTER SURGERY After surgery you will wake up in the recovery room, where your vital signs will be monitored, and your immediate postoperative condition will be carefully observed. Once the medical staff feels that you are doing well, you will be returned to your room in the hospital. Your surgeon will determine the best postoperative course for you. The day after your surgery, your surgeon may instruct you to use a brace for a period of time to assist with the spinal fusion process. Supervised by trained medical professionals, your surgeon may ask you to carefully sit, stand, or...

WHAT ARE THE POTENTIAL RISKS? POSSIBLE ADVERSE EVENTS Like other spinal system implants, the following adverse events are possible. This list is not exhaustive. • Delayed union or nonunion (pseudarthrosis). • Bending, disassembly or fracture of implant and components. • Loosening of spinal fixation implants may occur due to inadequate initial fixation, latent infection, and/or premature loading, possibly resulting in bone erosion, migration or pain. • Pain, discomfort, or abnormal sensations due to the presence of the device. • Pressure on skin where inadequate tissue coverage exists over the...

TECHNICAL INFORMATION SeaSpine® offers a wide range of rod materials to accommodate each patient’s needs. With straight and pre-contoured rod options, there are rods available for the most complex cases. The different rod characteristics, such as rod stiffness, bending strength, and springback will allow your surgeon to pick the correct rod for your case. Although rare, metal sensitivities and allergic reactions to foreign materials have been reported for orthopedic implant patients. The most common sensitivities, in order of their frequency, are to nickel, cobalt, and chromium. Implant sensitivity...
