To determine if you have snapping hip syndrome, your doctor will perform a physical examination and check your medical history. In some cases, imaging tests may also be necessary to further investigate your condition.
Physical exam and medical history
Your doctor will ask about your symptoms and other information such as the location of the snap, timing of the snap, duration, pain, and impact on your daily activities. The exam may include basic tests such as palpation of the affected area, Hip ROM, Muscle length tests, and Hula-hoop test.
X-ray is a diagnostic procedure that uses small amounts of radiation to create a picture of your spine. Radiography is used both to confirm the snapping hip syndrome and rule out any underlying conditions.
If physical exam cannot detect the syndrome, your doctor may recommend a dynamic ultrasonography to show the snapping of the iliotibial band over the greater trochanter. Dynamic ultrasound test can also detect associated health problems like tendonitis, iliopsoas bursitis or muscle tears.
This diagnostic procedure is used to visualise iliopsoas tendon under fluoroscopy after contrast dye is injected into the bursa, a fluid-filled sac that reduces friction between moving tissues.
Magnetic resonance imaging (MRI scan)
MRI can be used to rule out intra-articular causes. It is often done as an arthrogram study to show inflamed bursa.
