        abstract = {Background
Piriformis syndrome is an underdiagnosed cause of chronic buttock pain and sciatica resulting from compression or irritation of the sciatic nerve by the piriformis muscle. Image-guided piriformis injections are increasingly being used for both diagnostic and therapeutic purposes. Ultrasound guidance offers real-time visualization without radiation exposure, whereas fluoroscopy remains a commonly practiced conventional technique. This study aimed to compare the clinical efficacy and procedural outcomes of ultrasound-guided versus fluoroscopy-guided piriformis injections in patients with piriformis syndrome.

Methods
A retrospective comparative analysis was conducted on 30 patients diagnosed clinically with piriformis syndrome who underwent image-guided piriformis injection at a tertiary care center. Patients were divided into two groups based on the intervention technique: ultrasound-guided group (n=15) and fluoroscopy-guided group (n=15). All patients received a standardized injectate containing local anesthetic and corticosteroid. Pain intensity was assessed using the Visual Analog Scale (VAS) before the procedure and at follow-up. Procedural duration, patient comfort, radiation exposure, and complications were also evaluated. Statistical analysis was performed using paired and unpaired t-tests, with p <0.05 considered statistically significant.

Results
Both groups demonstrated significant reduction in post-procedural VAS scores compared to baseline (p <0.05). However, the ultrasound-guided group showed superior procedural comfort, shorter procedure duration, and avoidance of radiation exposure. Real-time visualization of the sciatic nerve and surrounding soft tissue structures improved needle placement accuracy in the ultrasound group. No major complications were observed in either group.
Conclusion
Both ultrasound-guided and fluoroscopy-guided piriformis injections are effective interventions for piriformis syndrome. Ultrasound guidance appears to provide additional advantages including real-time soft tissue visualization, reduced procedure time, improved patient comfort, and elimination of radiation exposure. Ultrasound-guided piriformis injection may therefore be considered a preferred technique in routine pain management practice.},
