Among the rare structural causes of IFI, osteochondroma, a benign bone tumour, can serve and present as a space-occupying lesion, reducing the ischiofemoral space and leading to soft tissue impingement.\n\nCase Report: We report a case of a 33-year-old male patient presenting with a six-month history of clicking and progressive left gluteal pain. Examination and imaging studies revealed a narrowed ischiofemoral space associated with an osteochondroma arising from the medial aspect of the lesser trochanter. Surgical resection of the lesion led to complete resolution of the symptoms and restoration of hip function.\n\nConclusion: This case highlights the need for a high index of suspicion for structural causes of IFI and underscores the importance of MRI in the diagnosis. Early surgical intervention for osteochondroma-induced IFI can result in excellent clinical outcomes.\n\nKeywords: Ischiofemoral Impingement \u2013 IFI, Osteochondroma \u2013 OC, Quadratus Femoris Muscle \u2013 QFM.<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i08.7790","type":"journal-article","created":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T11:55:13Z","timestamp":1786103713000},"page":"65-69","update-policy":"https:\/\/doi.org\/10.13107\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Lesser Trochanter Osteochondroma as an Etiology for Ischiofemoral Impingement: A case report"],"prefix":"10.13107","volume":"16","author":[{"given":"M Venu Gopal","family":"Reddy","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Star Hospitals, Hyderabad, Telangana, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Praveen","family":"Mereddy","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Star Hospitals, Hyderabad, Telangana, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G Shashi","family":"Kanth","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Star Hospitals, Hyderabad, Telangana, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G Veda","family":"Prakash","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Star Hospitals, Hyderabad, Telangana, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raghuram","family":"Yeshwanth","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Star Hospitals, Hyderabad, Telangana, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chennur S M S","family":"Mazhar","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Star Hospitals, Hyderabad, Telangana, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5271","published-online":{"date-parts":[[2026]]},"container-title":["Journal of Orthopaedic Case Reports"],"original-title":[],"deposited":{"date-parts":[[2026,9,13]],"date-time":"2026-09-13T08:45:28Z","timestamp":1789289128000},"score":1,"resource":{"primary":{"URL":"https:\/\/jocr.co.in\/wp\/2026\/08\/lesser-trochanter-osteochondroma-as-an-etiology-for-ischiofemoral-impingement-a-case-report\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"8","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.13107\/jocr.2026.v16.i08.7790","relation":{},"ISSN":["2321-3817"],"issn-type":[{"value":"2321-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]},"assertion":[{"value":"Research Article","name":"content_type","label":"Content Type"},{"value":"Yes","name":"crosschecked","label":"CrossChecked"},{"value":"Yes","name":"peer_reviewed","label":"Peer Reviewed"},{"value":"10.13107\/jocr.2026.v16.i08.7790","name":"published","label":"Published"},{"value":"Creative Commons Attribution","name":"license","label":"License","explanation":{"URL":"https:\/\/creativecommons.org\/licenses\/by\/4.0"},"group":{"name":"rights","label":"Rights"}}]}}
