INTERVERTEBRAL IMPLANT DEVICES |
摘要 |
Spinal implants for positioning between adjacent vertebrae. Some embodiments may comprise a pair of opposed sidewall surfaces, a pair of opposed frictional surfaces, a first end wall joining the pair of opposed sidewall surfaces, and a second end wall recessed at least in part and joining the pair of opposed sidewall surfaces. A fish-tailed structure may be positioned within the second end wall when viewed from one of the opposed frictional surface. The fish-tailed structure may be formed so as to extend at least substantially uninterrupted between at least one of the opposed sidewall surfaces and the opposed frictional surfaces. A retention structure, such as a hole, may be positioned within the fish-tailed structure. The hole may be configured to engage a surgical implantation device. |

1. A spinal implant, comprising:
a first sidewall; a second sidewall opposite from the first sidewall; a first frictional surface configured for engaging a first vertebra; a second frictional surface configure for engaging a second vertebra adjacent to the first vertebra; a first end wall joining the first sidewall and the second sidewall at a first end of the spinal implant; a second end wall joining the first sidewall and the second sidewall at a second end of the spinal implant opposite from the first end; and a retention structure positioned within the second end wall;
wherein the second end wall comprises a recess formed by a first wall portion and a second wall portion arranged at an angle to one another to form a fish-tailed structure;wherein the retention structure is positioned within the fish-tailed structure; andwherein the retention structure is configured to engage a surgical implantation device. |
