There was no significant difference in sensitivity (p=0.863) or specificity (p=1.00) between X-ray and CT scan. 1). p=0.988, Mann-Whitney Test. 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].

During this first appointment, theyll ask about your symptoms, conduct a physical exam and have you perform some movements if you are able. In a spinal fusion procedure, hardware is typically used to stabilize the spine while the bone graft fuses the vertebrae together. However, in 24 patients who underwent multilevel (more than two segments) instrumentation, there was no significant difference regarding extraction torque (p=0.437) between screws placed in the end segments (n=88) and those in the mid segments (n=103), as shown in Fig. Normal movement places small stresses on normal bones, which can actually flex a tiny bit; but motion also stresses the hardware, which is rigid - that's the point of putting it in; and since the metal won. Fusion, hardware removal, fusion to fix failed fusion, etc. The incidence of ACDF has been reported between -50%23-29. Cervical spine fusion can be performed routinely from the front of the neck or the back of the neck. Therefore, the reading of extraction torque was taken in 226 screws. 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. Comparison of teriparatide and bisphosphonate treatment to reduce pedicle screw loosening after lumbar spinal fusion surgery in postmenopausal women with osteoporosis from a bone quality perspective. xray of the offending foot showed the screw is on the move.

Both X-ray and CT had high specificity to detect screw loosening, but their sensitivities could be overestimated. PubMedGoogle Scholar. I do not expect complete fusion at this point, but the scan gives a good idea if the fusion process is progressing. Those with significant pedicle malplacement or destructive spine disorders, such as bone metabolic disease, were excluded from our study. The mean torque of screws, which were diagnosed as loosening by X-ray, was 0.530.65Nm, which was significantly lower (p<0.0001) than others (1.650.98).

Answer (1 of 13): Yes, it can happen, especially in an area which is being constantly used. Pedicle screw loosening is a common complication after spine surgeries. This study may indicate that some screw loosening is associated with subtle bacteria contaminating the screws. The screws were carefully studied, using a process called sonication, which assessed if small amounts of subtle non-aggressive bacteria were present. 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 Surgical screws, rods or metal plates are used.

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 the fractured vertebrae, the continuity of cortical and structure of trabecula were damaged, which might affect the stability of screw placed in it.
