We also found that pedicle screws in the lumbosacral junction (L4, L5, and S1) had significant higher extraction torque than those in other segments. 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. Can loosening screws in spine fusion be dangerous? Apparently this is common as the bones fuse either the screw goes deeper in or out - my case it is on the move outwards but he said 4 months is too early to have it removed. While the mean torque of loosened screws diagnosed by CT was 1.031.00Nm, which was also significantly lower (p=0.008) than others (1.711.00Nm).

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). Later on, the screw was visible on xray pictures and my pain was just confirmation. 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. Case report. The risk factors of screw loosening we found based on extraction torque were fixation in fractured vertebrae and non-fusion spine. demonstrated endoscopic extrusion of a screw after anterior cervical disc fusion, which caused esophageal perforation .

Additionally, the patient's ability to complete activities of daily living may be altered. Further study with larger simple size is needed to confirm the effect of screw length and diameter on extraction torque in the human spine. 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. Like any surgery, this procedure can also have long-term side effects. 1991;16(8 Suppl):S4227. Pedicle screw loosening: a clinically relevant complication?

There was no significant difference regarding the diameter or length of screws as shown in Fig. It is important to discuss treatment options with .
