Our Summary
This research paper was a study involving 51 people who had surgery to fuse their sacroiliac (SI) joint, a joint in the lower back, using 3D-printed triangular titanium implants. The operations were followed up at different intervals over five years to assess how the patients were doing. The measurements included pain levels, disability related to the SI joint, quality of life, and any changes observed in CT scans.
Results from the five-year follow-up, available for 36 out of the 51 patients, showed that the positive effects of the surgery, such as reduced pain and improved quality of life, were still present and not diminishing. The use of opioids for pain also decreased significantly from 57% of patients at the start of the study to 17% after five years. Tests of physical function also showed ongoing improvements from before the surgery.
The CT scans, interpreted by an independent specialist, showed no evidence of the implants breaking, moving, or sinking, and few late complications occurred due to the implants. The scans also showed that bone had grown onto the implants in all cases, and in 90% of cases, there was evidence of bone bridging, indicating successful fusion of the joint.
The researchers concluded that fusing the SI joint using 3D-printed triangular titanium implants resulted in immediate, significant, and long-lasting improvements in pain and quality of life, with better physical function, reduced use of opioids, and a low rate of needing further surgery. The implants successfully integrated with the bone and the joint fused as intended.

Doctor’s Tip
A doctor may advise a patient undergoing joint fusion surgery to follow a personalized physical therapy and rehabilitation plan to promote proper healing, improve strength and flexibility, and ensure long-term success of the procedure. It is important for the patient to follow all post-operative instructions and attend all follow-up appointments to monitor progress and address any concerns promptly. Additionally, maintaining a healthy lifestyle with regular exercise, a balanced diet, and avoiding smoking can help support the healing process and overall joint health.
Suitable For
Patients who are typically recommended joint fusion surgery are those who have chronic pain and disability related to the affected joint, despite conservative treatments such as physical therapy, medication, and injections. In the case of the study mentioned above, patients with sacroiliac joint dysfunction were recommended for joint fusion surgery using 3D-printed triangular titanium implants.
These patients may have conditions such as arthritis, degenerative joint disease, or injury that have not responded to other treatments. They may experience significant pain, limited mobility, and reduced quality of life due to the joint dysfunction. Patients who are considering joint fusion surgery should undergo a thorough evaluation by a healthcare provider to determine if they are appropriate candidates for the procedure.
It is important for patients to discuss the potential risks and benefits of joint fusion surgery with their healthcare provider and to have realistic expectations about the outcomes. Joint fusion surgery is a major procedure that requires a period of rehabilitation and recovery, but for many patients, it can provide long-lasting relief and improved function in the affected joint.
Timeline
Before joint fusion: Patients experience chronic pain, limited mobility, and reduced quality of life due to joint dysfunction. They may have tried various conservative treatments such as physical therapy, medications, and injections without success.
During joint fusion surgery: The surgeon uses 3D-printed triangular titanium implants to stabilize and fuse the joint. The surgery aims to reduce pain, improve function, and enhance the patient’s quality of life.
Immediately after joint fusion: Patients may experience some discomfort and need time to recover from the surgery. They will be monitored for any complications and given instructions on post-operative care.
1 year post-surgery: Patients start to experience significant improvements in pain levels, physical function, and quality of life. They may require physical therapy to regain strength and mobility.
5 years post-surgery: Patients continue to experience long-lasting benefits from the joint fusion surgery. Pain levels remain low, physical function continues to improve, and the need for opioid medications decreases. CT scans show successful fusion of the joint and integration of the implants with the bone.
Overall, the timeline before and after joint fusion surgery involves a gradual progression from chronic pain and limited function to significant improvements in pain relief, mobility, and quality of life. The surgery is shown to be effective in providing long-term benefits for patients with joint dysfunction.
What to Ask Your Doctor
What are the potential risks and complications associated with joint fusion surgery using 3D-printed triangular titanium implants?
