Minimally invasive versus open transforaminal lumbar interbody fusion: evaluating initial experience. There was no significant difference in sensitivity (p=0.863) or specificity (p=1.00) between X-ray and CT scan. 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. Pedicle screw loosening is a common complication after spine surgeries. The results showed a low but significant linear correlation between extraction torque and BMD. Skipping steps, not following normal protocol, ignoring you when you told them something that is a classic sign they did something wrong in your post op visit. volume14, Articlenumber:6 (2019) I am really not looking forward to have an addition fusion surgery.

Bone-compatible materials made from bone grafts or bone substitutes will be inserted between the vertebrae targeted for fusion. 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. Do you know whythe screws keep coming loose. 1994;19(10):115761. PubMedGoogle Scholar. X-ray revealed the hardware appeared to be in same position.
