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. 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. CAS This may suggest that spine screws could prophylactically be coated with antibiotic material prior to implantation, to help aid in fusion and surgical success.
