According to findings from a recently published case study, arachnoiditis ossificans is a relatively rare disorder with unclear etiologies that may not be able to be addressed through surgical intervention.
Researchers noted the case of a 29-year-old male patient who reported lower back stiffness and discomfort 23 months after undergoing posterior pedicle screw fixation and fusion for multiple lumbar spine fractures. The patient underwent a laminectomy at L2 and L3-4. Allogeneic bone was used to perform posterolateral fusion, and the surgeons noted at L2, bone fragments from the burst fracture had injured the dural sac along with some nerve roots.
