Document Summary

Fascia latae the stocking of the thigh, covers it entirely. Tensor fascia latae o iliac crest. Inferior gluteal nerve: extension of hip, external rotation. In greater trochanter: n superior gluteal nerve, a abduct thigh, medial rotation holds pelvis level in swing rotation phase or during weight bearing, gluteus minimus between anterior and inferior gluteal lines. In greater trochanter: n superior gluteal nerve, a abduct thigh, medial rotation, both are important in gait cycle, keep pelvis level to stabilize. If left limb is unsupported right gluteus medius and minimus work to tilt left pelvis up: clinical correlate = trendelenberg gait contralateral hip hop. Lateral rotation of hip: clinical correlate intragluteal injections- the top right corner if looking laterally. Piriformis irritation can cause irritation of the sciatic nerve: o anterior surface of sacrum. In greater trochanter: n nerve to piriformis, a , obturator internus o obturator membrane.
