Clinical diagnosis of IFI is challenging due to the overlap of other syndrome symptoms, which can delay appropriate management. Hip external rotation reduces the ischiofemoral and quadratus femoris (QF) spaces, compressing the QF muscle between the ischial tuberosity and the lesser trochanter. Ultrasound imaging can demonstrate dynamic entrapment of the QF, including assessment of symptom provocation and concurrently identify injury or irritation of nearby structures including the peri\u2010QF fat, sciatic nerve, and proximal hamstring tendons.<\/jats:p>","DOI":"10.1002\/jcu.70438","type":"journal-article","created":{"date-parts":[[2026,10,22]],"date-time":"2026-10-22T06:13:27Z","timestamp":1792649607000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Pain in the Buttocks: Practice Article for Sonographically Imaging the Quadratus Femoris and Ischiofemoral Impingement"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-1937-7903","authenticated-orcid":false,"given":"Elaine","family":"Tyzack","sequence":"first","affiliation":[{"name":"Central Queensland University School of Health, Medical and Applied Sciences, Brisbane Campus  Brisbane Australia"},{"name":"Lumus Imaging  Rockingham WA Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4088-2645","authenticated-orcid":false,"given":"Michelle","family":"Fenech","sequence":"additional","affiliation":[{"name":"Central Queensland University School of Health, Medical and Applied Sciences, Brisbane Campus  Brisbane Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,21]]},"reference":[{"key":"e_1_2_15_2_1","volume-title":"Grant's Atlas of Anatomy","author":"Agur A.
