Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study aims to evaluate whether the anatomical structure of the pelvis predisposes to the etiopathogenesis of the piriformis syndrome.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Piriformis syndrome group
Patients who were diagnosed as PS by diagnostic injection with ultrasound guidance
Ultrasound guided diagnostic injection
4 cc lidocaine %2 injection into the piriformis muscle was performed for the diagnosis of piriformis syndrome. It was performed by the ultrasound-guidance to increase the accuracy of the injection.
Age and sex match control group
Patients who were excluded from the diagnosis of PS and had anteroposterior (AP) direct radiographic imaging
No interventions assigned to this group
