Atlantoaxial Dislocation
Conditions
Brief summary
Conventional open surgery often requires extensive dissection of the muscle insertion points of the suboccipital muscle group during the insertion position and direction of the atlas axis screw, resulting in sustained postoperative occipital neck pain and movement dysfunction. In order to overcome the shortcomings of the prior art mentioned above, the present invention provides a self stabilizing fusion cage with a wing plate. During surgery, a thinner and smaller screw through the wing plate is used to achieve a secure connection between the atlas axis and the fusion cage. Due to the smaller screw size, the screw placement has higher safety. The purpose of this study is to compare the advantages of using this new fusion cage compared to traditional surgical instruments.
