Treatment of spinal cord compression caused by C2 osteochondroma with reconstruction and fusion after total resection: Case report and literature review.

Context: Osteochondroma is the most common benign tumor of the bone, but spinal osteochondroma is rare. We report a case of cervical osteochondroma in multiple exostoses arising from the lamina of the C2 vertebra, presenting with features of compressive myelopathy in a 22-year-old male. Total resection of the tumor and atlantoaxial fixation and fusion after reconstruction of the C1 posterior arch were performed.Findings: The patient recovered significantly. He was asymptomatic and no sign of recurrence was observed after one-year follow-up.

Conclusions

Osteochondroma should be considered as a rare cause of spinal cord compression. Entire removal of the tumor will result in complete decompression and can reduce the risk of recurrence. We provide a new approach to reconstruct after resection.
