The same surgeon (J.S. 165K views 4 years ago Dr. Gillard describes the case of a primary failed lumbar fusion, followed by a failed revision fusion. He could feel it, which is kind of freaky. If your fusion has not been successful they may put new hardware in its place. I am sorry for what you are going through. The screws were clustered into three clusters based on torque by Twostep Cluster as shown in Fig. In addition to chronic back pain, other symptoms of failed back surgery include neurological symptoms (eg, numbness, weakness, tingling sensations), leg pain, and radicular pain (pain that spreads from one area of the body to another, such as from your neck down to your arm). Like any surgery, this procedure can also have long-term side effects. In a spinal fusion procedure, hardware is typically used to stabilize the spine while the bone graft fuses the vertebrae together. lol I'm trying to be hopeful that this will at least alleviate most of my pain. The indications for screw removal included the following: (1) pedicle screw fixation for thoracolumbar fracture without fusion and imaging confirmed solid fracture union, (2) patients required screw removal that presented persistent axial para-midline back pain to palpation or abnormal foreign body sensation due to pedicle fixation with imaging confirmed solid fusion, and no other cause found, e.g., infection. Revision pedicle screws. Pedicle screws are placed above and below the vertebrae that were fused. Damaged hardware may be replaced or additional hardware may be inserted to ensure healing takes place as expected and so your spine can handle any future stress your body may put on it. Injury in the nerves: Naturally, when dealing with the spine, there is always a risk of suffering through nerve damage. The diagnostic criteria for loosening developed by X-ray include the radiolucent area (thicker than 1mm) around screw [4,5,6,7,8,9] and the double halo [4, 10] defined as the presence of radiolucent area and radiopaque rim at the same X-ray.

A possible explanation could be that surgeries performed in lumbosacral spine were mainly for degenerative disc diseases, which often required spinal fusion, while in the thoracolumbar spine, where operations were more likely for vertebral fracture, fusion were not always necessary. kyphosis (abnormal rounding of the upper spine) spinal weakness or instability due to severe arthritis, tumors, or infections spondylolisthesis (a condition in which one vertebra slips onto the. I have no pain from those cages at all. a Anteroposterior X-ray showed radiolucent zone and double halo around the screw (black arrow) which indicate screw loosening. The mean torque of screws was 1.551.00Nm. PubMedGoogle Scholar. Even if the screw is in a wall stud, it could get loose if someone daily wobbled the screw. 2023 MehtaSpine. There was no linear correlation between extraction torque and patients height (p=0.848), weight (p=0.196), BMI (p=0.125), and time interval between the primary surgery and screw removal surgery (p=0.965). When hardware is loose, it usually doesn't make a noise. Google Scholar. In both cases, bilateral S1 pedicle screws were inserted outwardly using a free-hand technique, and on one side, screws induced severe pain by impinging on an L5 root. The mean torque of screws placed in the lumbosacral junction (L4, L5, and S1, n=54) was 2.141.12Nm, which was significantly higher than those placed in other segments. The same X-ray and CT scan were scheduled before screw removal surgery to evaluate fracture union and spine fusion, as well as stability of instrumentation. 2010;28(6):E10. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. Those with significant pedicle malplacement or destructive spine disorders, such as bone metabolic disease, were excluded from our study. He is removing all hardware except for the upper flexible cage, which is doing its job at preventing further damage to the discs above my fusion. This picture shows metal artifact around screw tail in CT scan, which may confuse the interpretation of screw loosening. In the last 6 years I've had 5 back surgeries. Heres how.
