Stratification of Sacroiliac Joint Pain Patients and the Efficacy of Ultrasound-Guided Injection Treatment: A Retrospective Study

Ultrasound-guided SIJ injections provided early pain reduction, with a complication rate of 2.67% limited to transient, self-limited sensory changes. Predictive factors, such as the presence of metabolic disorders, offer insights into patient selection and individualized treatment planning. A clinical diagnosis supported by a positive response to diagnostic injection may be sufficient to confirm SIJ-related pain, although further investigation is needed to elucidate the underlying cause.
