Laterally insertable intervertebral spinal implant

An insertion tool and intervertebral implant kit, the kit comprising:

• an implant comprising:
• an implant body having a front end, a rear end and a pair of spaced apart first and second side walls extending between the front and rear ends with the front and rear ends extending in a transverse direction and a central axis of the implant body extending from the rear end to the front end, wherein the rear end defines a first fastener hole having a first central axis and a second fastener hole having a second central axis, the first and second central axes extending parallel to one another at an acute angle relative to the implant body central axis in the transverse direction;
• and
• an insertion tool comprising:
• a tool body extending from a proximal end to distal end, the distal end defining a face and the tool body defining at least two fastener passages with respective third and fourth central axes,
• wherein the insertion tool is configured to support the implant such that the implant rear end extends along the face and the third and fourth central axes align with and are parallel to the first and second central axes, respectively, in the transverse direction.

A retraction assembly comprising:

• a mounting plate with at least one mount extending therefrom, the mounting plate having a chamber extending therein with an adjustment screw extending into the chamber;
• a lateral adjustment arm having a first end with a shaft which is positioned in the chamber and engages the adjustment screw such that rotation thereof causes the lateral adjustment arm to move laterally relative to the mounting plate, the second end of the lateral adjustment arm defining a pivot mount;
• a pivot member pivotally connected to the lateral adjustment arm at the pivot mount with a second adjustment screw extending from the lateral adjustment arm and engaging the pivot member such that rotation thereof causes pivoting of the pivot member relative to the lateral adjustment arm;
• and
• a retraction blade connected to the pivot member.
