Ultrasound-Guided Interfascial Hydrodissection for Gluteal Myofascial Pain in Piriformis Syndrome: A Prospective Study
Sponsor: Istanbul University - Cerrahpasa
Summary
This randomized, double-blind prospective trial investigates whether ultrasound-guided interfascial hydrodissection using 10% dextrose is more effective than dry needling in treating gluteal myofascial pain coexisting with piriformis syndrome. Following diagnostic piriformis injection response, eligible patients will be randomized into two treatment arms and followed at 1 hour, 1 week, 1 month, and 3 months. The primary hypothesis is that interfascial hydrodissection will provide superior long-term analgesic outcomes due to fascial separation, neuromodulation, and nociceptor suppression.

Interventions
Ultrasound-Guided Interfascial Hydrodissection
Ultrasound-guided interfascial hydrodissection is performed in the interfascial plane between the gluteus maximus and piriformis muscles.
Ultrasound-Guided Gluteus Maximus Dry Needling
Ultrasound-guided dry needling is performed on the gluteus maximus muscle without fluid administration.
