Therefore, the reading of extraction torque was taken in 226 screws. Google Scholar. A clinical and radiologic review is presented of a patient who underwent rigid fixation with L4-5 interbody fusion and L3-4 posterolateral dynamic stabilization with Zimmer Dynamic-to-Optima (DTO) hybrid fusion to non-fusion system (Zimmer Spine, Minneapolis, MN) with hydroxyapatite coated pedicle screws that exhibited lucency on radiographic studies which subsequently disappeared. These cookies track visitors across websites and collect information to provide customized ads. Original question: What are the symptoms of a spinal fusion screw coming loose? The process of spinal fusion is costly . Surgeons needed to be more cautious when assessing screw loosening merely according to radiological examination, and aware of that screws in fractured vertebrae or non-fusion surgery were vulnerable to loosening. Lumbar fusion permanently stops movement between two vertebrae. Now I know why! Also I will not re fuse her as it didn't work the first time. Spinal nerve damage that can result in weakness, pain, loss of sensation, and loss of bowel or bladder control The vertebrae above and below the fusion are more likely to wear away, leading to more problems later Leakage of spinal fluid that may require more surgery Headaches Bleeding and blood clots Later on, the screw was visible on xray pictures and my pain was just confirmation. The x rays showed a halo around the screw. 4 and 5. 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. Persistent Pain The University of Maryland Spine Center states that the most common complication of lumbar fusion surgery is persistent pain 3. Hence, further studies with larger sample size and stratified data according to different factors will be needed to better understand the prevalent of pedicle screw loosening. Pedicle screw loosening is a common complication after spine surgeries. It's a pain like sciatica: a sharp stabbing pain that runs in a thin band down your leg.

Depending on the patient, the bones can fuse quickly, or they can take some time. Patients with fusion surgery were considered to get better stability than those without fusion; hence, screws in fused spine might share lower strain and have higher torque. 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. Injury in the nerves: Naturally, when dealing with the spine, there is always a risk of suffering through nerve damage. 2005;10(2):1336. 2011;31(4):E9. hardware removed after a spinal fusion - shared with permission.

Privacy 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). Cookies policy. The debris elicited an inflammatory cytokine-mediated particulate-induced response through increased expression of intracellular TNF-alpha, increased osteoclastic activity, and cellular apoptosis. A rod is used to connect the screws which prevents movement and allows the bone graft to heal. I am hoping that the hardware can just be removed if my fusion is complete. Significant difference was found between different segments (p<0.001) as shown in Fig. Surgical screws, rods or metal plates are used. A postoperative complication of a surgery for a back injury is to sustain a broken screw. It can occur without symptoms so the patient doesn't even know he or she has it. b Lateral X-ray showed that the same screw was pulled out (white arrow). When the screws get loose, it can also result in infections. The relatively low related coefficients might be due to the existence of numerous confounding factors, and these results indicated that the failure risk of instrumentation increased with age and osteopenia/osteoporosis, which was widely credited but rarely proven in vivo with mechanical measurement. What can't you do after spinal fusion? 6). The key factor regarding investigation of screw loosening is the assessment of whether a screw is loosened or not, which is traditionally based on radiological approaches [3].
