Lateral & Anterior Aspects of Leg Prof. Dr. Selda Önderoğlu NEU MED Department of Anatomy Cutaneous Nerves Lat. cutaneous n. of leg (from common peroneal n) Superf. peroneal n. (from common peroneal n) Saphenous n. (from femoral n) Superficial veins: Great saphenous v. (courses ant. To medial malleolus) Small saphenous v. (courses post. To lat. malleolus Deep fascia of leg (Fascia cruris) Ant & post intermuscular septa At ankle region thickens and form: Sup & inf extensor retinacula  muscles Anterior compartment Tibialis anterior Extensor digitorum longus Fibularis (peroneus) tertius Extensor hallucis longus Lateral compartment Fibularis (peroneus) longus Fibularis (peroneus)brevis Tibialis anterior muscle Tibialis anterior m. O: Lat. condyle & upper half of lat. surface of tibia, interosseous membrane I: Medial cuneiform & 1st metatarsal bone F: Extension & inversion of foot Extensor digitorum longus m. Extensor digitorum longus m. O: Lat. condyle of tibia, upper 3/4 medial surface of fibula, interosseous memb I: Dorsal aponeurosis 2- 5 digits (same as in hand) F: Extension of fingers 2-5 & foot Fibularis(peroneus) tertius m. Extensor hallucis longus m Fibularis(peroneus) tertius m. O: Lower 1/3 medial surface of fibula, interosseous membrane I: Base of 5th metatarsal bone F: Extension & eversion to foot Extensor hallucis longus m O: Middle 1/3 of medial surface of fibula, interosseous membrane I: Base of distal phalanx of hallux (big toe) F: Extension of hallux & foot, inversion of foot All mm. On the ant.aspect of leg are innervated by the: Deep peroneal nerve (branch of common peroneal n.) Prof. Dr. H. Selçuk Sürücü Origin&insertions of mm. Of anterior &lateral aspect of leg Lateral aspect of leg:Fibularis ( peroneus) longus m O: Head & upper 2/3 lateral surface of fibula, intermuscular septa I: Medial cuneiform bone & 1st metatarsal bone F: Flexion & evertion of foot N. Superf. Peroneal n. Fibularis(peroneus) brevis m O: Lower 2/3 lateral surface of fibula, ant & post. intermuscular septa Ins:base of 5th metatarsal b. N: superf. Peron. N. F: Flexion & evertion of foot Anterior aspect Lateral aspect Anterior tibial a. Muscular branches Ant recurrent tibial a Post recurrent tibial a Ant lat malleolar a Ant med malleolar a Continues as the: Dorsalis pedis a  Superficial fibular (peroneal) n. Muscular brr. to lat mm Ant & lat cutaneous brr  Deep fibular n Muscular brr to ant mm Articular branches Courses together with the ant. Tibial artery Prof. Dr. H. Selçuk Sürücü Common fibular n Most commonly injured peripheral nerve  Palpable Structures Patella Patellar lig Tuberosity of tibia Tibial & femoral condyles (joint line) Med & lat collateral lig Menisci Tendon of biceps Head of fibula Video links https://www.youtube.com/watch?v=s1 NMrkX59qE ant.&lateral aspect leg. https://www.youtube.com/watch?v=Y EVuykTeJhA ant.&lateral aspect leg. https://www.youtube.com/watch?v=8 3_ctEOFkhM ant.&lateral aspect leg.
