Arthrodesis, sacroiliac joint, percutaneous or minimally invasive (indirect visualization), with image guidance, includes obtaining bone graft when performed, and placement of transfixation device

Sacroiliac (SI) joint arthrodesis is a surgical procedure aimed at creating a solid fusion between the sacrum, which is the triangular bone at the base of the spine, and the ilium, the uppermost part of the pelvis. This procedure is typically indicated for patients suffering from severe, persistent pain in the SI joint, often resulting from conditions such as fractures or arthritis. The goal of the arthrodesis is to alleviate pain by stabilizing the joint through the process of ossification, which is the formation of bone tissue. During the procedure, a bone graft, which can be either harvested from the patient's own body (autograft) or obtained from a donor (allograft), is utilized to facilitate this fusion. The technique employed is percutaneous or minimally invasive, meaning it involves smaller incisions and less disruption to surrounding tissues compared to traditional open surgery. Image guidance, often through fluoroscopy, is used to accurately navigate to the joint and ensure proper placement of the graft and any necessary implants. This method not only enhances precision but also contributes to a potentially quicker recovery time for the patient.
