摘要： The invention is directed to an interbody fusion device comprises a load bearing component and a retention component and further comprises two bone screws that pass through the retention device and into the vertebral bodies. When implanted, the construct is flush with the anterior face of the vertebras and provides support and temporary fixation for the ultimate fusion of the vertebral bodies.

摘要： A method and apparatus is provided for use in spinal fusion procedures. An interbody fusion device has a first piece that is a load bearing device designed to bear the axial loading from the end plates of adjacent vertebrae. A second piece of the interbody fusion device is a retention component whose primary functions are to prevent migration of the load bearing device and loss or migration of graft material from within the load bearing device. A secondary function of the retention component is to address fixation of fasteners when the surgeon is confronted with a challenging access to adequate boney structures due to excessive curvature/angulation of the vertebrae column, minimal invasive surgery techniques, danger to surrounding vascular or neurological tissues, poor bone quality, or similar surgical complications. A tertiary function of the retention component is to provide better alignment and stabilization of misaligned vertebrae when spondylolisthesis is a significant factor. One or more fasteners secure the retention component to each of the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion.
摘要翻译： 提供了一种用于脊柱融合手术的方法和装置。 体内融合装置具有第一部件，该第一部件是承载来自相邻椎骨的端板的轴向载荷的承载装置。 体内融合装置的第二部分是保持部件，其主要功能是防止承载装置的移动和承载装置内的移植材料的损失或迁移。 保留组件的次要功能是解决紧固件的固定问题，因为外科医生由于椎骨柱的过度曲率/角度，最小的侵入性手术技术，对周围的血管或神经组织的危险而面临充分的骨架结构的挑战， 骨质量差，或类似手术并发症。 保留组件的三级功能是当脊椎前移是重要因素时，提供更好的对齐和稳定的不对准的椎骨。 一个或多个紧固件将保持部件固定到承载装置上方和下方的每个椎骨。 紧固件使得椎骨的端板将端板压缩到承载装置以促进适当的融合。
