Abstract

The invention provides an anterior-posterior combined atlantoaxial fusion device which comprises an occipito-cervical fusion plate, the occipito-cervical fusion plate comprises an occipital bone plateand two connecting plates, the occipital bone plate is of an arc-shaped structure, and the two connecting plates are connected to the two ends of the occipital bone plate respectively, a connecting piece is provided, a first end of the connecting piece is connected with the occipito-cervical fusion plate; an atlantoaxial support fusion device is connected with the second end of the connecting piece, and the atlantoaxial support fusion device is provided with a compression position and an open support position. According to the technical scheme, the problem that in the prior art, after the atlantoaxial fusion device is connected with a bone, the stress is uneven, and consequently the atlantoaxial fusion device is prone to losing efficacy is effectively solved.

Description

technical field [0001] The invention relates to the technical field of atlantoaxial vertebrae, in particular to an anteroposterior combined atlantoaxial vertebrae fusion device. Background technique [0002] Atlantoaxial joint dislocation refers to the loss of the normal alignment relationship between the joints between the first segment (atlas) and the second segment (axis) of the cervical spine, resulting in compression of the medulla oblongata and high cervical spinal cord, and the direction of the vertebral artery and blood flow. Changes in dynamics; dizziness or syncope may occur in mild cases, and quadriplegia or even death due to respiratory failure may occur in severe cases. Due to its high disability and fatality rate, atlantoaxial joint dislocation is one of the hot spots and difficulties in spinal surgery research worldwide. Atlantoaxial arthrodesis is currently recognized as the most effective method for the treatment of atlantoaxial joint dislocation. Posterio...
