Abstract
At least one bone fixation device comprising a stem having a maximum outer diameter is inserted into the sacroiliac joint through a minimally invasive incision path sized approximately at or about the maximum outer diameter of the stem in soft tissue, into the iliac bone, across the sacroiliac joint and into the sacrum. The stem is inserted through the incision path to a position within the sacroiliac joint between the iliac bone and the sacrum, to fuse the sacroiliac joint, without invasive joint preparation, removal of cartilage, or scraping at or near the sacroiliac joint. Desirably, at least a portion of the stem includes a surface permitting bony in-growth.
