This question was originally posted by Claire, who wrote: I am 13 weeks post-op spinal fusion L4-L5. g No significant difference of extraction torque was found among different screw length. We also tested the average torque of newly implanted screws and found that 1.02Nm was lower than the low limit of 95% confidence interval of newly implanted screws. Spinal hardware is used in a number of different procedures to help increase stability or facilitate healing after an injury. pedicle screws) may be used as an internal splint to hold the spine while it fuses after spine surgery.

Those with significant pedicle malplacement or destructive spine disorders, such as bone metabolic disease, were excluded from our study. senior attending doctor), who was blinded to the extraction torque and patient information. Spinal fusion often involves placing metal screws with rods or plates to immobilize bones and allow them to fuse, or grow together. 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. Symptoms of Loose Screws after Spinal Fusion - Mehta Spine What Happens when Spine Hardware Breaks? | Dr. Sinicropi Patients with fusion surgery were considered to get better stability than those without fusion; hence, screws in fused spine might share lower strain and have higher torque.
