Brief summary
iFuse TORQ for the Treatment of Sacroiliac Joint Dysfunction (STACI) is a prospective, multicenter, study of SIJ fusion using the iFuse TORQ implant system.
Detailed description
This trial is a prospective, multicenter, study of SIJ fusion using the iFuse TORQ implant system. The goal of the trial is to demonstrate the effectiveness of the device for its intended use.

Currently participating in another interventional clinical trial
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Improvement from baseline in SI joint (SIJ) pain | At baseline, 1-, 3-, 6-, 12-, and 24-months | Improvement from baseline in SIJ pain as measured by numeric rating scale (0- no pain to 10- worst pain imaginable). |
| Improvement from baseline in disability | At baseline, 1-, 3-, 6-, 12-, and 24-months | Improvement from baseline in disability as measured by Oswestry Disability Index |
| Improvement from baseline in quality of life | At baseline, 1-, 3-, 6-, 12-, and 24-months | Improvement from baseline in aggregate quality of life and individual domains as measured by PROMIS-29. |
