The treatment of craniocervical instability caused by diverse conditions remains challenging. Different techniques have been described to stabilize the craniocervical junction. The authors present 2 cases in which tumoral destruction of the C-1 lateral mass caused craniocervical instability. A one-stage occipitoaxial spinal interarticular stabilization (OASIS) technique with titanium cages and posterior occipitocervical instrumentation was used to reconstruct the C-1 lateral mass and stabilize the craniocervical junction. The ipsilateral vertebral artery was preserved. The OASIS technique offers single-stage tumor resection, C-1 lateral mass reconstruction, and stabilization with a loadsharing construct. It could be an option in the treatment of select cases of C-1 lateral mass failure.
由多种病因引起的颅颈交界区不稳定的治疗仍然具有挑战性。已经描述了多种稳定颅颈交界区的技术。本文作者报告了2例因C1侧块肿瘤性破坏导致颅颈交界区不稳定的病例。采用钛网枕颈关节突间稳定术（OASIS）联合后路枕颈内固定技术重建C1侧块并稳定颅颈交界区。同侧椎动脉得以保留。OASIS技术提供了一期肿瘤切除、C1侧块重建以及通过负载分担结构实现稳定。它可能是治疗特定C1侧块破坏病例的一种选择。
