The goal of this observational study is to evaluate the correlation between ultrasound measurements of quadratus femoris muscle thickness and ischiofemoral distance, as well as clinical parameters, with MRI measurements in patients diagnosed with ischiofemoral impingement (IFI) through MRI imaging and clinical examination. The main questions it aims to answer are: Is there a correlation between ultrasound and MRI measurements of quadratus femoris muscle thickness and ischiofemoral distance in patients with clinically and radiologically confirmed IFI? How do clinical parameters relate to ultrasound and MRI findings in these patients? What is the intra- and inter-rater reliability of ultrasound measurements for these parameters? Participants will undergo ultrasound measurement of quadratus femoris muscle thickness and ischiofemoral distance, assessment of clinical parameters related to ischiofemoral impingement, and measurements performed twice by two independent raters to assess intra- and inter-rater reliability. Researchers will compare ultrasound and MRI measurements as well as clinical parameters to determine if ultrasound can serve as a reliable and cost-effective alternative for diagnosing ischiofemoral impingement.
