Important lower limb nerves:

Femoral nerve: extend knee; sensory loss on anterior thigh, medial leg and foot; weak hip flexion, loss of knee extension.

Obturator nerve: adduct thigh; medially rotate thigh; sensory loss on medical thigh.

Tibial nerve: flex knee; extend knee; plantar flex foot; flex digits; inversion.

Common peroneal (fibular) nerve: flex knee; foot drop.

Superficial peroneal (fibular) nerve: eversion; dorsal foot sensory loss except first web space.

Deep peroneal (fibular) nerve: dorsiflex foot; extend digits; inversion; foot drop; sensory loss on anterolateral leg and dorsum of foot.

Superior gluteal n.: stabilize pelvis; Trendelenburg gait.

Inferior gluteal n.: extension of hip; lateral thigh rotation; can't rise from sitting position; can't climb stirs.

Sciatic nerve: weakened extension of thigh; no knee extension; no function below knee.

Arterial supply of lower limb:
• External iliac a., femoral a., popliteala., anterior tibial a., posterior tibial a., obturator a.

Femur supplied by medial femoral circumflex artery.

Knee joint:
• Strengthened medially and laterally by the medial and lateral collateral ligaments, respectively.
• Strengthened anteriorly and posteriorly by the anterior and posterior cruciate ligaments, respectively.
• Triad knee injury: medical collateral ligament, medical meniscus, and anterior cruciate ligaments.

Ankle joint:
• Medical collateral (deltiod) ligament and lateral collateral ligament injured in eversion and inversion ankle injuries, respectively.

Additional Notes:
• Spasm of peroneus (fibularis) longus spasm: pes planus (flat feet; eg., from playing too much soccer).
• M. peroneus longus: planter flexion and eversion.
• Feel pulse at: dorsal aspects of feet lateral to extensor hallucis longus tendons.
