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 nerve:

Stabilize pelvis; Trendelenburg gait.

Inferior gluteal nerve:

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.

Arteries of the Lower Limb:

Blood Supply of Femur:

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.
