Thigh: tensor fasscia latae, fascia latae, and iliotibial band
IT band syndrome (theories)
Common theory (friction): a lot of friction as femur moves from anterior to posterior (flexion to extension) with each stride, the IT band rubs across lateral femoral condyle and that causes pain and inflammation in IT band BUT there are fibrous strands between IT band and femur (so they will move together and not cause friction) Newer theory (compression of fat pad): instead of friction, it is due to compression of a fat pad between IT band and femur. Strengthening of TFL and GM to a point where there is tension on IT tract and compresses adipose tissue (highly innervated) causing pain Suggested treatment: ?? rest, stretching, pain management
tensor fasciae latae
Origin: (ASIS) anterior portion of iliac crest Insertion: (IT band) iliotibial tract Innervation: superior gluteal nerve (L4, L5, S1) Function: hip flexor, abduction, medial rotation of thigh, knee stabilization "tenses up IT band when it contracts" Blood supply: superior gluteal artery, lateral circumflex femoral artery
IT Band (iliotibial band)
Origin: continuation of the tensor fascia latae Insertion: lateral condyle of the tibia, Gerdy's tubercle
fascia lata
entire fascia surrounding thigh (IT band is portion of it), superior boarder/attachment (cont): inguinal line, ASIS to pubic tubercle (saphenous opening, where great saphenous V. enters into the femoral V.) inferior boarder (continuous): crural fascia
