Broken Surgical Screw in the Spine - SpineUniverse As expected, extraction torques of pedicle screw after fusion surgery (n=142) were significantly higher than those in non-fusion surgery (n=84) (p=0.001), as shown in Fig. I am still very conscious of the incision site and the feeling of the muscles and hardware in my back. I do have a doctor appt next week, but previously was told my CT scan showed the fusion is solid.

Pedicle screws of non-fusion surgery placed in fractured vertebrae had significantly lower extraction torque and, therefore, could be vulnerable to loosening. c Screw placed in fractured vertebrae showed significantly lower extraction torque than those in non-fractured vertebrae. p=0.673, Mann-Whitney Test. The main symptom is usually pain, but many things can cause pain; the best way to know if a loose screw is actually the cause is to do x-rays, and then compare them with your older films. 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). As there is not enough research conducted to formulate a textbook definition of what the effects might be in the long run, it becomes important to know what they could be. If such findings are detected, a second operation for revision should be considered as soon as possible to prevent potentially fatal complications.

The fusion of the vertebrae in the lower back can be used to alleviate pain and degeneration from a variety of low back conditions. 2. Other factors that could cause bone loss or destruction, such as infection surrounding the implant, bone tumor, metabolic diseases, and microfracture due to excessive loading, are risk factors of pedicle screw loosening. If any pain is still remaining, then that too will continue to get lesser gradually. What are the Treatments for Failed Back Surgery Syndrome? Meanwhile, there was no significant difference in extraction torque regarding the screw design (polyaxial vs. monoaxial) and location (placed at the end segment vs. at the middle segment).

Indications for L5 S1 fusion are debilitating pain and dysfunction arising from degenerative disc disease, slipped disc, fractures, recurrent herniation, sciatica, scoliosis, and spinal canal narrowing. Patients might feel like they got better for a little while, but then started to get worse again.
Aftermath of Spinal Fusion Surgery: Complications, Potential - Cellaxys Roellinghoff reported that in 64 patients treated with multilevel pedicle screw fixation, 35(54.69%) patients showed radiographic signs of screw loosening [16]. Pseudarthrosis means false joint and refers to movement that occurs at the fused site. Cite this article.
