Endoscopic Osteochondroma Resection for Treatment of Ischiofemoral Impingement Through Posterior Approach: A Case Report.

Narrowing of the ischiofemoral space leading to the entrapment of neurovascular structures is the pathologic basis of ischiofemoral impingement (IFI). In our clinical practice, we encountered a patient with secondary IFI because of an osteochondroma in the lesser trochanter region, presenting with typical posterior hip pain. Traditional surgical methods typically involve lesion resection through a posterolateral approach to the hip, with only a few patients reported using hip arthroscopy. We present a modified posterior hip arthroscopic technique for resecting an osteochondroma near the lesser trochanter. This technique allows for rapid access to the lesion site and provides clear visualization of the sciatic nerve under arthroscopy, facilitating safe and thorough lesion resection.Level of evidence V, Case Study.
