Our objective in this report is to describe two cases with atlantooccipital (O-C1) osteoarthritis treated with posterior occipitocervical fusion. Methods and results: Two patients presented with unilateral suboccipital pain, which was refractory to conservative treatment. One patient suffered from long-standing rheumatoid arthritis while the other patient did not have pertinent medical issues. After non-diagnostic plain film imaging, CT scan demonstrated unilateral osteoarthritis of the atlantooccipital and atlantoaxial joint in both patients who subsequently underwent posterior O-C2 fusion with resolution of their preoperative symptoms. Conclusions: This is, to our knowledge, the first case report which specifically focused on surgical treatment of atlantooccipital osteoarthritis. Occipitocervical fusion is a treatment option for patients with atlantooccipital osteoarthritis when suboccipital pain is not responsive to conservative treatment.
