Ischiofemoral impingement (IFI) is a rare cause of hip pain that is due to an abnormal contact between the lesser trochanter of the femur and the ischium.
This is the result of a narrowing of the ischiofemoral space,
leading to muscular,
tendon and neural changes. This anomaly was first described in patients after total joint replacement but it has since been described in young patients with no history of trauma in association with anatomical or functional disorders. 1 Clinically,
Methods and Materials
We retrospectively revised all hip MRI carried out in our institution in the last 4 years (from January 2009 to December 2012).
There were a total of 90 studies of 89 patients between 20 and 67 years old (mean age of 38). We reviewed the studies using the PACS. We also reviewed all the clinical histories of our patients,
paying special attention to the clinical onset symptoms and the radiology reports from the MRI studies,
as well as the background and follow-up after treatment of our...
Introduction : Ischiofemoral impingement is caused bya narrowing of the ischiofemoral space and leads to muscular,
tendon and neural changes. Patients present with nonspecific hip and groin pain,
raising a wide range of differential diagnoses. 2.
Differential diagnosis of hip pain : Positive results for IFI in our study were seen in 11 studies corresponding to 10 patients (12%) between 28 and 64 years old (mean age of 44).
One patient had an operation after diagnosis and an MRI was...
Ischiofemoral impingement is a rare pathology that causes hip pain in young patients but it seems to be more common than we thought,
especially in cases of women with coxa valga and dysplasia. Fig. 20 Radiologists and clinicians should bear this diagnosis in mind.
We must take into accountthe imaging findings in this disorder in order to depict this anomaly.
A correct MRI study with clinical correlation is usually sufficient to make the diagnosis.
