Dr. Ebraheim’s educational animated video describes the condition known as snapping hip syndrome.
What is snapping hip syndrome?
An audible click or snapping sensation with hip movement.
May or not be painful.
Can occur due to three types of the condition:
1-Internal type
2-External type
3-Intra-articular type
1-Internal type
Iliopsoas tendon snap
•Snapping of the iliopsoas tendon over the iliopectineal eminence.
•Iliopsoas tendon will snap over the pelvic brim
Iliopsoas bursitis
•Inflammation of the bursa that lies between the front of the hip joint and the iliopsoas muscle.
•Ultrasound or MRI may be normal
•May reveal bursal fluid anterior to the hip joint.
•Iliopsoas injection can be diagnostic
Abduction and external rotation of the hip will also help in the diagnosis.
2-External type
Iliotibial band syndrome
•The thickened iliotibial band snaps over the bony greater trochanter of the femur.
•The patient may develop trochanteric bursitis, adhesions, gluteus maximus inflammation or edema.
Diagnosis of iliotibial band syndrome
•Direct palpation of the greater trochanter.
•Put the patient on the side
•The hip is placed in extension and rotate the hip till a pop is felt.
Ober’s test
Best clinical test
•It is a clinical examination test used to access tightness of the iliotibial band.
•The patient should lay on the side with the unaffected leg on the bottom.
•The examiner will then slowly abduct the leg with the knee in flexion and the hip in extension.
•When the IT band is tight, the test is positive and the patient will be unable to adduct the legs and the knees will not come together.
3-Intra-articular type
Hip joint labral tear or loose body.
•Painful labral tears are other causes of snapping hip syndrome.
•Decreased range of motion
•A painful click in the joint.
•Normal labrum is a black triangle structure shown as a normal healthy acetabular labrum. Dye is in the lateral recess.
•In acetabular or labral tear, MRI arthrogram shows contrast between the medial aspect of the labrum and acetabulum. Dye is medial.
