    • A surgical spine implant comprises a solid wedge shape device body is such that said polygonal shape with decreased height posterior and several surfaces that contours to the anatomy of the spine intervertebral space without complex machining across radiuses. The diminished height posteriorly provides for the angulations necessary to accommodate and ensure maintenance of the normal spinal alignment resulting in posterior extension angulations. The device provides ease of application of bone grafts. Such as for impaction of cancellous bone grafts after placement of the device and narrow posterior aspect easily directs grafts. This minimizes the problem of bone grafts hanging up behind the device either to the right or the left of the medial or lateral, which prevents the displacement of the device or prominence of the bone grafts near the spinal canal. The recess hole in the device accommodates a holding insertion tool and ease of bone graft packing “fill” to ensure a tight fit and immobile the attachment of the disc to the lower vertebrae.
    • 手术脊柱植入物包括固体楔形装置主体,使得所述多边形形状具有降低的高度后部和多个表面,其轮廓与脊椎椎间空间的解剖结构不进行跨半径的复杂加工。 高度向下的降低提供了适应并确保维持正常脊柱对准所需的角度,从而导致后延伸角度。 该装置提供了骨移植物的易于应用。 例如在装置放置后的松质骨移植物的碰撞和狭窄的后方容易引导移植物。 这最大限度地减少了悬挂在装置后面的骨移植物到内侧或外侧的右侧或左侧的问题,这阻止了装置的移位或靠近椎管的骨移植物的突出。 装置中的凹孔容纳保持插入工具,并且容易地进行骨移植包装“填充”,以确保紧密配合并且将盘的附接固定到下椎骨上。
