Percutaneous intervertebral hydrogel ( @entity968 ) implantation is a current treatment procedure that aims to restore hydration of a degenerated disc. There have been a few studies that claim that @entity968 is successful for @entity158 relief as the intervertebral space restores its hydration and elasticity. This procedure is reported to be indicated for discogenic @entity1643 and mild @entity158 as it contributes to disc restoration. In this report, the authors describe the case of a 43-year-old @entity1 who was admitted with @entity1643 . Muscle strength in dorsiflexion of the right ankle and right toe was 3/5. The @entity1 had undergone hydrogel implantation for L4-5 intervertebral disc restoration 2 days prior to presentation. There was a significant increase in the @entity1 's complaints after hydrogel implantation, and acute @entity425 in the right ankle and toe had developed. Magnetic resonance imaging of the lumbar vertebrae, which was performed before the hydrogel implantation, showed a significant narrowing of the L4-5 disc space height, and a disc herniation that extended to the right neural foramen and caused compression of the dural sac. The @entity1 underwent surgery immediately. The sequestered disc fragment that caused a prominent @entity850 in the spinal canal, as well as hydrogel fragments, was removed. There was an improvement in the @entity1 's complaints and @entity51 postoperatively. In this paper, a very rare complication is reported. In @entity1 who have @entity158 after intervertebral hydrogel implantation and who develop a @entity51 , the migration of the applied material into the spinal canal should be considered.

Migration of fragments into the spinal canal after intervertebral XXXX implantation: an extremely rare adverse effect.
