Ultrasound Confirmation of Fluoroscopically Guided Piriformis Muscle Injections
Subjects will have failed conservative treatment, including, but not limited to oral medications, physical therapy, manual manipulation, and/or alternative medicine. They will be evaluated by a spine specialist in the Spine Division of the Department of Orthopaedics and will be scheduled for a piriformis muscle (PM) corticosteroid injection.
Subjects Will Have Failed Conservative Treatment.

|Official Title:||Ultrasound Confirmation of Fluoroscopically Guided Piriformis Muscle Injections: Does Accuracy Improve Efficacy?|
- Ultrasound evaluation of fluoroscopically guided needle placement in the piriformis muscle. [ Time Frame: Following fluoroscopic guidance of the needle placement and prior to the injection, the needle position will be evaluated by ultrasound. ] [ Designated as safety issue: No ]Following the fluoroscopically guided needle placement, the non-invasive ultrasound probe will then be placed on the skin with gel and will be used to visualize the needle tip and evaluate the accuracy of the fluoroscopically guided needle placement. Needle placement will be recorded as either inside or outside the piriformis muscle.
