• An 100 - 200 unit injection of BoNT-A, performed intramuscularly, leads to weakness and atrophy of the injected muscle and can potentially reversing any nerve compression that has occurred.
• Ultrasound guidance is non-invasive and its successful use during BoNT-A administration in PMS is well documented in the literature.
• This treatment approach is relevant for those in whom the disease has progressed to cause significant difficulty in daily living activities and is refractory to first line treatments.
• This study had a statistically significant reduction in visual analog scale pain scores, which is a validated, subjective measure for acute and chronic pain, as well as flexion, adduction, and internal rotation scores, which measures indicate pressure placed on the sciatic nerve by the piriformis muscle.
• Multiple recent cases reports in the literature have also documented the resolution of pain and return of function with BoNT-A injections.
