Abstract:Non-focal hip and groin pain can frequently be a diagnostic problem, particularly if it is related to uncommon causes such as ischiofemoral impingement. The vast majority of published cases of ischiofemoral impingement are caused by osseous changes of the ischiofemoral interval. We describe an unusual case of ischiofemoral impingement caused by an intermuscular lipoma. Surgical resection of the tumour and histology confirmed the lipomatous nature of the tumour, with subsequent resolution of symptoms. To the be… Show more
“…The overall quality of studies was 78.1% based on the JBICAC ranging from 62.5 to 100%. The four open surgical treatment articles were subdivided based on the treatment modality [ 2 , 30 , 35 , 38 ]. Two articles reported open surgical resection of the exostosis [ 35 , 38 ].…”

“…However, subsequent MRIs showed incremental narrowing of the IFS and an abnormal signal in the quadratus femoris muscle [ 16 ]. In chronic cases resistant to conservative therapy, a tumour mass has to be taken into account, as well [ 30 ]. Thus, in cases of suggestive symptoms with no initial visible pathology, repeat MRI studies may be warranted.…”
Ischiofemoral impingement (IFI) is a rare cause of hip pain defined by a narrowing of the space between the lateral aspect of the os ischium and the lesser trochanter of the femur. Several underlying anatomic, functional and iatrogenic pathologies have been identified for symptomatic IFI in native hip joints and after total hip arthroplasty. Clinical symptoms vary but most commonly consist of pain of the lower buttock and groin including the inner thigh, and a snapping or clunking phenomenon is often reported. Symptoms may be provoked by a combined extension, adduction and external rotation during physical examination and during long-stride walking. Radiographs of the pelvis and an axial or false-profile-view of the hip as well as magnetic resonance imaging (MRI)-scans should be obtained to strengthen the diagnosis. On MRI, the quadratus femoris muscle signal and the space confined by the anatomic structures surrounding the muscle, the quadratus femoris space, are to be assessed. Targeted infiltration of the muscle can be helpful both diagnostically and therapeutically. The literature on differential diagnoses and treatment options for IFI is limited; therapeutic suggestions are offered only in case reports and series. With this work, we aim to give a systematic approach to the non-surgical and surgical treatment options for IFI based upon the current literature and the authors’ personal experience.
“…26 A final report described a case of IFI due to a lipomatous tumor that was excised through an open posterior approach in the lateral position. 27 The open approach may improve cosmesis because it is made in the gluteal crease.…”
