From the Research

The most common cause of fused sacroiliac (SI) joints in a 76-year-old male is degenerative joint disease, which is a natural process of aging that can lead to the fusion of the SI joints over time. This condition is often associated with wear and tear of the joint cartilage and can be exacerbated by factors such as osteoarthritis, trauma, or previous surgeries. Other potential causes of SI joint fusion include ankylosing spondylitis (AS), diffuse idiopathic skeletal hyperostosis (DISH), reactive arthritis, and psoriatic arthritis, but these are less common than degenerative joint disease as primary causes of complete SI joint fusion in elderly males 1.

The diagnosis of SI joint fusion can be confirmed through imaging studies such as X-rays, CT scans, or MRI, which would show the characteristic bridging bone formation across the SI joints. Management of SI joint fusion focuses on symptom control with anti-inflammatory medications, physical therapy, and lifestyle modifications, as the fusion itself is irreversible once established 2, 3.

It's worth noting that the prevalence of SI joint fusion increases with age, and it is more common in males than females 1. In addition, minimally invasive sacroiliac joint fusion has been shown to be an effective treatment option for patients with degenerative sacroiliitis who have failed nonoperative management 4. However, the treatment approach should be individualized based on the patient's specific condition, medical history, and overall health status.

In terms of morbidity, mortality, and quality of life, it's essential to prioritize a comprehensive treatment plan that addresses the patient's symptoms, functional limitations, and overall well-being. This may involve a multidisciplinary approach, including pain management, physical therapy, and lifestyle modifications, to optimize the patient's quality of life and minimize the risk of complications or adverse outcomes 2, 3.
