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 plate, two connecting plates and a cervical bone plate, the two connecting plates are connected to the two ends of the occipital bone plate respectively, the cervical bone plate is connected to the two connecting plates in a bridging mode, and through holes are formed in the two connecting plates; a bridging plate comprises a plate body and a filling block arranged on the plate body; and a bridging screw penetrates through the through hole and is matched with the filling block so as to connect the occipito-cervical fusion plate and the bridging plate together. According to the technical scheme, theproblem 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 present invention relates to the technical field of atlantoaxial vertebrae, in particular to an anterior and posterior combined atlantoaxial vertebra fusion device. Background technique [0002] Atlantoaxial dislocation refers to the loss of the normal abutment relationship between the first and second cervical vertebrae (the atlas) and the second vertebrae (the axis), resulting in compression of the medulla oblongata and the high cervical spinal cord, and the direction and blood flow of the vertebral artery. Dynamic changes; mild dizziness or syncope, severe cases can lead to quadriplegia, or even respiratory failure and death. Due to its high disability and fatality rate, atlantoaxial dislocation is one of the hotspots and difficulties in spine surgery research worldwide. Atlantoaxial joint fusion is currently recognized as the most effective method for the treatment of atlantoaxial joint dislocation. Posterior atlantoaxial fusion has convenien...
