Pedicle screw loosening: the value of radiological imagings and the identification of risk factors assessed by extraction torque during screw removal surgery. Poor wound healing. The screw, especially a larger diameter screw, is acting like a wedge so the board can actually be split apart around the screw. 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.

In this process, two or more vertebrae are fused together and healed into one solid bone. Treatment for failed back surgery syndrome may include physical therapy, nerve blocks, medications, injections or a chronic pain management program. Spine. Internal Medicine 32 years experience. 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.

Loosening of the screws does not necessarily mean fusion will not eventually occur, or those symptoms are due to the loose screws. Botolin S, Merritt C, Erickson M. Aseptic loosening of pedicle screw as a result of metal wear debris in a pediatric patient. Spine. The debris elicited an inflammatory cytokine-mediated particulate-induced response through increased expression of intracellular TNF-alpha, increased osteoclastic activity, and cellular apoptosis. 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). Some reports showed that increasing length and diameter could increase the stability of pedicle screw [24, 25], which had not been observed from our results. What are the Treatments for Failed Back Surgery Syndrome? In a spinal fusion procedure, hardware is typically used to stabilize the spine while the bone graft fuses the vertebrae together. Spine. Life After Back Surgery: Broken and Loose Screws Can Screw Up a Person Extraction torque of pedicle screws inserted in fractured vertebrae was significantly lower than those in non-fractured vertebrae (p=0.009); meanwhile, screws of non-fusion surgery had lower extraction torque when compared to those in fusion surgery (p=0.001). Now they are going to extend the rods up further, does that sound right.

Berjano P, Bassani R, Casero G, Sinigaglia A, Cecchinato R, Lamartina C. Failures and revisions in surgery for sagittal imbalance: analysis of factors influencing failure. 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. This picture shows metal artifact around screw tail in CT scan, which may confuse the interpretation of screw loosening. Spinal fusion is generally safe. . Why do screws come loose after spinal fusion? Prinz V et al. As there is not enough research conducted to formulate a textbook definition of what the effects might be in the long run, it becomes important to know what they could be.

Traditionally, it was assessed by radiological approaches, both X-ray and CT (computed tomography) scan, while reports using mechanical method to study screw loosening after spine surgery are rare. Anecdotally, I have wondered if some loose screws occurred due to persistent wobbling of the screw in the bone. I do have a doctor appt next week, but previously was told my CT scan showed the fusion is solid. Sometimes a small ligament will snag as one moves, and then it pops back into place. Original question: What are the symptoms of a spinal fusion screw coming loose? If you have had a lumbar fusion, then there is always the risk of a hardware malfunction, failure or breakage. I consider the analogy of a screw placed in a wall. An epidural catheter (a thin, flexible tube) may be inserted into the back at the conclusion of the operation to help control pain. Meanwhile, stress shielding can lead to a decrease of stress transferred through the bone tissue, which can reduce bone mineral density and remodel the bone surrounding the screw. Screws inserted in the lumbosacral junction (L4, L5, and S1) showed the highest torque. Or perhaps file a law suit against him? In these cases, spinal cord stimulation (SCS) or narcotic pumps may be used for pain control. Lumbar fusion permanently stops movement between two vertebrae. Low back pain may persist even though patients experience significant relief from the radiating pain in their legs. Just recently My MRI shows that my fusion did not hold and I have a loose screw! Straightening of the cervical lordosis. f No significant difference of extraction torque was found among different screw diameter.

It is a treatment for a variety of diseases and conditions of your spine. Questions Regarding If the Screw Can Be Removed? c Screw placed in fractured vertebrae showed significantly lower extraction torque than those in non-fractured vertebrae. The titanium alloy pedicle screws (Johnson&Johnson, USA; Medtronic, USA; Stryker, USA; Kanghui Med, China; FULE, China) with diameter of 4.0 to 6.5mm and length of 30 to 55mm were used in the primary surgeries. Conventional lateral and anteroposterior radiographs were taken before and at 3 to 6months after primary surgery. Furthermore, the sensitivity and specificity of the X-ray criteria of loosening could be confounded by many factors, such as metal image artifact, intestinal gas, and display angle. If imaging tests did not reveal any hardware damage, only a tissue disturbance, you may be able to get by with physical therapy, controlled exercise and an extended period of rest. Broken Screw Back Surgery Lawsuit But I really can't stand the narcotics they give. A review of literature reveals a paucity of case reports detailing work-up and successful .

Meanwhile, we compared our extraction torque data with X-ray and CT scan findings, the result showed that the specificity of both imaging approaches were excellent, and the peri-screw osteolysis present both in X-Ray and CT scan could indicate low extraction torque of screw anchor, but their sensitivities were less than satisfactory (24% and 22% respectively), regarding detection of screw loosening. Screw loosening may become a worsening problem due to the aging of population and the increasing number of osteopenic and osteoporotic patients.

CAS Sanden [20] reported a 64% sensitivity of X-ray in 79 screws and a 35% rate of screw loosening, but their definition of a loosed screw was an extraction torque of 0.4Nm or less as there were no screws with and extraction torque between 0.4Nm and 0.75Nm.
