Therefore, a broken screw won't move very much in your spine, so if it's not causing you issues now (you don't have any pain, so it sounds like it isn't), the screw isn't likely to be a problem later on. Jianting Chen or Hui Jiang. Survivorship analysis of pedicle spinal instrumentation. Both X-ray and CT had high specificity to detect screw loosening, but their sensitivities could be overestimated. 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. The process of spinal fusion is costly . If the screws are loose I will not remove them as it will give her back pain. MedHelp is not a medical or healthcare provider and your use of this Site does not create a doctor / patient relationship. Thanks. The main symptom is usually pain, but many things can cause pain; the best way to know if a loose screw is actually the cause is to do x-rays, and then compare them with your older films.

What can't you do after spinal fusion? 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]. Sanden and colleagues [20], in a cohort study of 21 patients who underwent pedicle screw removal surgery, reported that the radiolucent zones around pedicle screws was associated with lower extraction torque, but they did not employ CT scan or evaluate the risk factors for loosening according extraction torque. Answer (1 of 13): Yes, it can happen, especially in an area which is being constantly used. CAS Surgical screws, rods or metal plates are used. In adults, scoliosis can cause a lot of pain, and this is the number-one reason adults with scoliosis opt for spinal fusion as their treatment path. What are the symptoms of a failed laminectomy?

During this first appointment, theyll ask about your symptoms, conduct a physical exam and have you perform some movements if you are able. Surgery in L5 S1 Fusion is denoted by its level. L lumbar vertebrae, S sacrum, T thoracic vertebrae. J Neurosurg Spine. Spinal tumors all affect the spine, but they can happen in different ways and cause different symptoms. Nevertheless, like X-ray, the details about how the screw loosening was evaluated by CT scan were obscure and the assessment was subjective too. In this process, two or more vertebrae are fused together and healed into one solid bone. However as it stands regarding pain im at level 10, can't walk or stand as my back feels unstable and like I have an axe in my back that I can feel with the tiniest of movement. It may take 1-3 hours depending on your own condition. It is a treatment for a variety of diseases and conditions of your spine. If you notice any of the potential signs of a broken piece of spine hardware, contact your surgeon right away. The screws at the ends of implant were supposed to share more strain and be vulnerable to loosening [3]. Spinal fusion surgery might also be performed when a patient has: Fractured (broken) bones from a traumatic injury Abnormal curvatures of the spine from conditions like scoliosis An unstable or weak spine due to tumors or infections Degenerative disc disease resulting in mechanical back pain c CT scan showed no gap around the same screw.

There were 26 screws placed in 13 fractured vertebrae. Ko CC, Tsai HW, Huang WC, Wu JC, Chen YC, Shih YH, Chen HC, Wu CL, Cheng H. Screw loosening in the Dynesys stabilization system: radiographic evidence and effect on outcomes. 16 Other complications of ACDF include spinal cord injury (<1%), nerve root injury (0.9%), post-operative haematoma (1.7%), recurrent laryngeal nerve injury (2%-4%), vertebral artery injury (<1%), surgical wound infection Our results showed a low but significant linear correlation between extraction torque and BMD (p=0.010, R2=0.304, F=8.296) as well as age (p=0.045, R2=0.123, F=4.345), indicating pedicle screw in aged patients or those with low bone density may be less stable according to mechanical measurement, as shown in Figs. While methods for spine surgery have significantly improved over the years, a patients recovery still depends on their own diligence and dedication, so following the Dos and Donts of spinal fusion recovery is a must. McAfee PC, Weiland DJ, Carlow JJ. Spine J. With a failed fusion, the patient's initial symptoms may return, or they may experience new problems. In my practice, I often order a CT scan around 3 months to verify the instrumentation is not loose and there are early signs of bone growth (fusion). Your surgeon will normally re-open your original incision. This study was a prospective and clinical study and was approved by the Nanfang Hospital, Southern Medical University Institutional Review Board. Although lumbar spine fusion surgery is one of the most commonly performed spine surgical procedures, it is associated with the risk of perioperative complications as well as death [1].

Injury to blood vessels or nerves in and around the spine. 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. There can be various complications that might come along with it. David Chang, MD-PhD, DABNS, Roseville, MN, 6 Tips For Recovering After Spine Surgery. Degeneration of the adjacent discs. There was no significant difference in sensitivity (p=0.863) or specificity (p=1.00) between X-ray and CT scan. Naturally, there are some risks associated with the surgery.

Spinal hardware is used in a number of different procedures to help increase stability or facilitate healing after an injury. g No significant difference of extraction torque was found among different screw length. The average value should be $1.5 Million - $5.5 Million on a broken screw back surgery case. The mean torque of screws placed in fractured vertebrae was 1.030.63Nm, which was significantly lower (p=0.009) than those in non-fractured vertebrae, as shown in Fig. Lee et al. How do I know if my spinal fusion has failed? lol I'm trying to be hopeful that this will at least alleviate most of my pain. Therefore, we intended to investigate the pedicle screw loosening rate using extraction torques during instrumentation removal surgery, and compare it with X-ray and CT image findings. I am having the same problem with the screws coming loose. Revision pedicle screws. J Bone Joint Surg Br.

Meanwhile for the past years all was okaytill Just recently where I started seeing a sports medicine doctor, orthopaedic, physical therapy, and massage, but nothing has helped. In our study, we also found a significant linear correlation between BMD and extraction torque, indicating pedicle screws in aged patients or patients with lower BMD might be less stable due to lower extraction torque. An instrumented fusion can fail if there is not enough support to hold the spine while it is fusing. Chronic back pain. Ohtori employed both CT scan and X-ray and the results showed that CT scan was more sensitive than X-ray [11]. Prinz V et al. p=0.988, Mann-Whitney Test. e Extraction torques of pedicle screw after fusion surgery (n=142) were significantly higher than those in non-fusion surgery.

The maximum extraction torque was recorded while unscrewing the screw using torque gauge with a range of 0.06 to 6.00Nm (Park Tool, China). The debris elicited an inflammatory cytokine-mediated particulate-induced response through increased expression of intracellular TNF-alpha, increased osteoclastic activity, and cellular apoptosis. These are few things to keep in mind whenever an individual opts for spinal fusion surgery.

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. Like any surgery, this procedure can also have long-term side effects. Esses SI, Sachs BL, Dreyzin V. Complications associated with the technique of pedicle screw fixation.
