Lower limb的幾個重要區域

1.subinguinal space & femoral triangle--anterior thigh

• femoral triangle→邊界：inguinal ligament 、sartorius、adductorlongus；floor：pectineus、iliopsoas；roof：fascia lata、cribriform fascia、"part of sartorius"
• femoral artery穿過中間，頂點底下有deep femoral A&V
• 由外往內→NAV，其中A與V在femoral sheath內，神經沒被包起來
• femoral sheath包覆：femoral artery、femoral vein、femoral canal
• femoral→medial：lacunar ligament，lateral：femoral vein，anterior：inguinal ligament，posterior：pectineus
• subinguinal space被iliopectineal arch分成，前方：vascular lacuna，含A、V、淋巴；後方：muscular lacuna，含N、iliopsoas
• 股神經→分成saphenous nerve、nerve to vastus medialis
• 股三角的出口接到adductor cannal

2.adductor cannal & adductor hiatus

3.Tarsal tunnel

4.obturator cannal--medial thigh

5.greater sciatic foramen--gluteus

6.lesser sciatic foramen--perineum
