2Vessels•Femoral A becomes the Popliteal A•Around the knee there are 4 arteries:– Sup & Inf, Lat & Med Genicular A.•Popliteal A. gives off Ant Tibial A.– Penetrates the Interosseous Membrane•Then Post Tibial gives off Fibular A.Veins• Deep– Ant and Post Tibial V.•Join to become Popliteal V• Superficial– Saphenous V runs medially•Joins Femoral inferior to triangle– Small Saphenous V runs dorsally•Joins Popliteal above knee
3Innervation•Sciatic courses posteriorly•Sup to Knee it splits into Tibial & Fibular•Fibular N– Wraps laterally around fibula and splits– Superficial (l) & Deep Fibular nn•Saphenous N (fr. Femoral N)– Wraps medially around tibia to medial maleollusInnervation - 2• Posteriorly– Tibial N•Courses along post aspect of Tibia to foot•Gives off many local nerves•Continues to foot medially•Gives rise to Sural N (S) & Plantar nn–Supplies skin on post & lat leg, lat foot• Anteriorly– Sup & Deep Fibular nn continue to foot•Lateral and Medial respectively
