SI Joint Stabilization with Unio

SI joint fusion is a minimally invasive surgical procedure that aims to stabilize the SI joint by fusing the Sacroiliac Joint.

Using the Unio designed implants, the procedure is done through a small incision and typically takes less than an hour. Unlike other SI joint fusion methods, Unio uses allograft made of dense cortical bone that is placed directly into the SI joint. The bone from which these implants are formed is a natural material that enhances bone fusion and resists migration or loosening of the implant over time.

Unio allows for fusion and stabilization of the SI joint in eligible patients where appropriate non-surgical treatment has failed. Stabilization of the SI joint may provide immediate relief of your symptoms.

The Unio approach to SI joint fusion surgery may be performed in a less invasive way than traditional Sacroiliac Fusions, allowing for less blood loss and potential quicker recovery time.

Unio is intended for sacroiliac joint fusion for conditions including Degenerative Sacroiliitis and Sacroiliac Joint Disruptions.
