Question 1: To compare the effectiveness of fusion versus denervation for chronic sacroiliac joint pain after failed conservative management |
1. Patient satisfaction |
Fusion |
|
The majority of patients report satisfaction after both treatments. The rate was higher among denervation subjects; however, this was based on one study with nine subjects. |
|
Denervation |
|
|
2. Improvement in pain |
Fusion |
|
Both treatments rendered mean improvements in pain of 3.5–4.9 points on a 10-point scale among studies reporting this outcome; however, only two studies reported this outcome for fusion. |
|
Denervation |
|
|
3. Improvement in functional outcome |
|
Both treatments rendered an improvement in functional outcome based on the Oswestry disability score of 14.0–18.0 points; however, only one fusion study and two denervation studies reported this outcome. |
Question 2: To compare the safety of fusion versus denervation for chronic sacroiliac joint pain after failed conservative management |
4. Complications |
|
Rates of complications were higher among fusion studies (13.7%) compared to denervation studies (7.3%); however, it is important to note that these are different study populations and the follow-up times are much shorter among denervation studies. |
5. Infections |
|
Only fusion studies reported infections (5.3%). No infections were reported among denervation patients. |
