Abstract

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.

Dependent claims

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;
and
wherein the retention structure is configured to engage a surgical implantation device.
