iliotibial band
- Discussion:
- an overuse phenomenon which is common in
runners (more common w/ downhill running);
- pts usually have pain over lateral femoral epicondyle, which is caused by inflammation resulting from
friction as iliotibial tract slides over the condylar prominence;
- syndrome may be more common in runners w/ genu varum &
hyperpronated feet;
- this may occur due to the need for the lower limb to generate a valgus moment at the point of maximum
stance phase flexion inorder to balance out the opposing forces;
- a varus limb alignment will require a larger valgus moment at the time of stance phase, which then causes
increased friction between the IT band and the lateral epicondyle;
-
clinical findings:
- athletes usually complains of pain over the lateral aspect of knee;
- pain over lateral femoral epicondyle, due to inflammation resulting from friction as iliotibial tract slides over condyle;
- there is tenderness where iliotibial band slides over lateral prominence or at Gerdy's tubercle;
-
diff dx:
- includes lateral meniscal tear, discoid lateral meniscus,
popliteus tendinitis, and patellofemoral pain syndrome;
-
treatment:
- non operative rx includes stretching, orthosis, and steroid injections;
- in chronic cases bursectomy and lateral tendon resection may relieve symptoms;
- Snapping Syndrome of the hip:
- usually caused by the thickened posterior border of iliotibial band or anterior border of
maximus muscle near its insertion;
- tense fasical band catches as it slides over superior margins of greater troch as hip is flexed, adducted, or internally rotated;
- snapping may also occur from iliopsoas tendon over bony prominence at the lesser trochanter;
