Aggressive osteoblastoma of the cervical spine and resultant complication due to swollen oxidized regenerated cellulose: A case report.

Background: Osteoblastomas, although rare, are benign primary bone tumors, with cervical spine involvement being exceptionally uncommon. Late diagnosis, especially in aggressive cases, can lead to surgical challenges. Oxidized regenerated cellulose (ORC) used for hemostasis may result in complications if left in the surgical field.
Case Description: An 8-year-old female presented with six months of intractable neck pain accompanied by swelling, hindering proximal right upper extremity evaluation. Motor strength was intact distally, with normal reflexes and no hypoesthesia. Imaging revealed a C4-5 facet joint lesion necessitating surgery. Intraoperative hemorrhage prompted ORC application, which led to postoperative arm pain and C5-6 radiculopathy. Subsequent surgery alleviated these symptoms.
Conclusion: Osteoblastomas, despite their benign classification, may exhibit aggressive characteristics, warranting en-bloc resection. Cervical spine osteoblastomas, due to their vascular nature and proximity to vital structures, complicate surgical interventions. ORC, a commonly used hemostatic agent, may induce compression complications, and early intervention is critical for patient recovery. This case underscores the intricacies of managing aggressive osteoblastomas in the cervical spine and highlights potential ORC-related complications. Surgeons must exercise caution when using ORC and consider postoperative risks. Prompt intervention and meticulous planning are paramount for favorable outcomes in such cases.
