Clinical Features Requiring Sacroiliac Joint Arthrodesis in Patients with Sacroiliac Joint Pain.

PURPOSE: This study aimed to reveal the clinical features requiring sacroiliac joint (SIJ) arthrodesis, which was performed for patients who complain of severe SIJ pain.

METHODS

The differences in clinical features between a surgical treatment group (n=20) and a conservative treatment group (n=66) were investigated. All patients were definitively diagnosed with SIJ pain by the use of SIJ injections.

RESULTS

Six significant features were identified in the surgical treatment group, namely, sitting tolerance (<15 minutes), walking with a cane, pain in the supine position, pain while lying on the painful side, numbness in the lower limbs, and any accident that induced SIJ pain (P<0.01). Univariate logistic regression analysis revealed that sitting tolerance <15 minutes (odds ratio : 31.73), pain in the supine position (13.07), and pain while lying on the painful side (18.30) showed a high odds ratio.

CONCLUSIONS

Sitting tolerance (<15 minutes), walking with a cane, pain in the supine position, pain while lying on the painful side, numbness in the lower limbs, and a history of any accident that induced SIJ pain may be considered as indicators for surgery after >?6 months of continued substantial conservative treatment.
