System and method for an intervertebral implant assembly

An intervertebral implant assembly for stabilization and decompression of two adjacent spinal vertebras, comprising:

• an implant having a U-shaped body shaped and dimensioned to be placed between two adjacent vertebras, wherein said U-shaped body comprises a rounded front end, an open back end, first and second elongated components extending from the rounded front end, forming the U-shaped body and ending at the open back end and at least one rigid strut extending from and connecting opposite inner side surfaces of the first and second elongated components;
• wherein the first and second elongated components comprise first and second extensions, extending from and being perpendicular to the back ends of the first and second elongated components, respectively, and wherein said first and second extensions protrude inward;
• a first through-opening formed in the space between the front end, the rigid strut and the opposite inner side surfaces of the front portions of the first and second elongated components;
• and
• a second through-opening formed in the space between the open back end, the rigid strut and the opposite inner side surfaces of the back portions of the first and second elongated components;
• wherein the first and second elongated components comprise first and second extensions, extending from and being perpendicular to the back ends of the first and second elongated components, respectively, and wherein said first and second extensions protrude inward and do not converge together;
• wherein the first extension comprises a first rectangular portion at the bottom, a rounded portion in the middle and a second rectangular portion at the top, wherein the second rectangular portion is set outward relative to the first rectangular portion at a plane parallel to the first rectangular portion;
• wherein the second extension comprises a first rectangular portion at the top, a rounded portion in the middle and a second rectangular portion at the bottom, wherein the second rectangular portion is set outward relative to the first rectangular portion at a plane parallel to the first rectangular portion;
• an inserter tool, wherein said inserter tool comprises:
• an elongated inner shaft extending along a first direction and comprising a flat disc component at the distal end, wherein the flat disc component extends perpendicular to the first direction and comprises first and second protrusions extending from the sides of the flat disc component and wherein said first and second protrusions are configured to be inserted in the open back end of the U-shaped body and to be placed behind the first and second extensions of the first and second elongated components, respectively;
• a middle sleeve surrounding the elongated shaft and comprising an attachment jaw at its distal end and an L-shaped opening at its proximal end;
• an outer sleeve surrounding the middle sleeve;
• and
• wherein said first and second extensions are used for locking the implant onto said inserter tool via a twist locking mechanism.
