Engineered bone graft implant and methods of using the same

A substantially cylindrical bone graft implant sized and configured for endoscopic introduction to a bone of a patient, the bone graft comprising:

• a first end, a second end, and a longitudinal axis extending from the first end to the second end;
• a cortical-bone-facing portion that is porous extending along a first side of the bone graft implant from the first end to the second end;
• a cancellous-bone-facing portion that is porous extending along a second side of the bone graft implant from the first end to the second end;
• one or more reliefs formed on at least one of the cortical-bone-facing portion and the cancellous-bone-facing portion, the one or more reliefs being configured to allow the bone graft implant to be flexed when the bone graft implant is being introduced to the bone of the patient, wherein the one or more reliefs are selected from the group consisting of U-shaped reliefs, scalloped reliefs, and V-shaped reliefs;
• and
• a cannula that axially traverses a length of the bone graft implant,
• wherein the cancellous-bone-facing portion of the bone graft implant is configured to be placed proximate to a surface of the bone of the patient,
• wherein the cortical-bone-facing portion comprises cortical bone, and
• wherein the cancellous-bone-facing portion comprises cancellous bone.
