How SImmetry® works

Everything you need to know about the SImmetry procedure.

SI fusion

SImmetry is an SI fusion procedure. This means an implant is used, which is designed to:

  • Keep your SI joint from moving

  • Give you immediate relief

  • Provide long-term stability

The SImmetry procedure is different from other treatment options because it creates a true fusion of your SI joint. Although this is the gold standard when it comes to spinal procedures, not all treatment options provide fusion. In addition, SImmetry is minimally invasive, which can lead to a much shorter recovery time compared to other fusion techniques.

SImmetry works in a three-step process:

  • First, cartilage is removed, encouraging your body’s own healing process

  • Then, bone graft material creates a bridge for your body to create new bone

  • Finally, screws are inserted to keep your SI joint in place, for immediate and long-term pain relief

What to expect before, during, and after your SImmetry procedure

The SImmetry procedure is minimally invasive, meaning your hospital stay, and recovery, may be shorter than expected.

Before the procedure

Make plans to have someone drive you to the procedure and bring you home as well as help out around the house for a day or two. You’ll also want to pack a bag for your stay, in the event you do have to stay the night. Be sure to follow any instructions your surgeon provides for you leading up to the procedure.

During the procedure

The SImmetry procedure takes about an hour to complete. You’ll be under a general anesthetic, so you won’t be awake. You’ll be lying face down, and the surgeon will only make two small incisions.

After the procedure

When you first wake up, you may experience some pain and swelling at the incision sites. This can be treated with ice and medication if needed. Once you are recovered enough to head home (usually within the same day), your doctor will provide you instructions for the remainder of your recovery.
