2 Shape Diamond Inter-Muscular Space Boundaries 1 Upper Lateral Upper Medial 1- Biceps Femoris Semitendinosus 3- Semimembranosus Lower Medial Medial Head of Gastrocnemius Lower Lateral 5- Plantaris 6- Lateral Head of Gastrocnemius

3

4 Shape Boundaries Floor Popliteal Surface of Femur 2- Back of the Capsule of Knee Joint 3- Popliteus Muscle & Fascia Vertical Sectional View

5 Shape Boundaries Floor Roof 2- Small Saphenous Vein 12 Skin Superficial Fascia Deep Fascia * End of Small Saphenous Vein *Medial Cutaneous Nerves of Thigh *Lateral Cutaneous Nerves of Calf Pierced by : 1- Posterior Cutaneous Nerve of Thigh

6 Shape Boundaries Floor Roof Contents In Addition to Diagram * Genicular Branch of Posterior Division of Obturator Nerve * Popliteal Lymph nodes * Popliteal Fat

7 Contents to Be Discussed Popliteal Artery Popliteal Vein Lateral Popliteal Nerve Medial Popliteal Nerve

8 Contents to Be Discussed Popliteal Artery

9 Origin continuation of femoral artery Termination Course & Relations deepest structure in the popliteal fossa passes downward and laterally from the upper medial boundary of the fossa downward to the inferior angle Deep Relations : Floor of the fossa Superficial Relations Upper : semimembranosus Middle : Medial Popliteal N & Popliteal V Lower : Gastrocnemius

10 Popliteal Artery Branches Muscular Muscular Genicular Genicular Sural Sural Terminal Terminal Hamstrings & Calf Superior Medial & Lateral Inferior Medial & Lateral Middle Anterior & Posterior Tibial

11 Anastomosis Around Knee Joint 1-GENICULAR BRANCHES OF POPLITEAL ARTERY. 2- BRANCHES FROM FEMORAL ARTERY. 3-BRANCHES FROM ANT &POST TIBIAL ARTERIES.

12 Contents to Be Discussed Popliteal Artery Popliteal Vein

13 Origin At lower border of Popliteus by Venae Comitantes of Ant & Post Tibial a. Termination Continue as Femoral V. Tributaries Small Saphenous Vein 5 Genicular Veins Muscular Veins

14 Contents to Be Discussed Popliteal Artery Popliteal Vein Lateral Popliteal Nerve

15 Lateral Popliteal Nerve (Common Peroneal Nerve) L4,5 & S1,2 Origin Lateral & smaller of the 2 terminal branches of Sciatic Nerve Course & Relations 1- enter fossa through its upper angel lateral to medial popliteal N 2- descend downward laterally along medial border of Biceps Femoris Muscle 3- leave fossa through lateral angel 4- descend behind head of fibula curve around its neck inside substance of Peroneus Longus Muscle Termination

16 Lateral Popliteal Nerve (Common Peroneal Nerve) L4,5 & S1,2 Branches Lateral Popliteal Nerve Muscular Muscular No Muscular Branches in the Fossa S upply Short head of Biceps Femoris in the back of the thigh Cutaneous Cutaneous Sural Communicating Nerve Lateral Cutaneous Nerve of the Calf Articular Articular Superior Lateral Genicular Inferior Lateral Genicular Recurrent Genicular - Arise near end of the nerve - Pierce upper part of Tibialis Anterior -Ascend through substance of Extensor Digitorum Longus

17 Contents to Be Discussed Popliteal Artery Popliteal Vein Lateral Popliteal Nerve Medial Popliteal Nerve

18 Medial Popliteal Nerve (Tibial Nerve) L4,5 & S1,2,3 Origin Medial Terminal Branch of Sciatic Nerve Termination Become Posterior Tibial Nerve Course - Enter through Upper Angle - Most Superficial Structure -Leave through Lower Angle Coverings : - Upper part : Hamestring - Lower Part : Gastrocnemius Relation with Vessels : Lateral Superficial Medial

19 Medial Popliteal Nerve (Tibial Nerve) Branches Tibial Nerve Articular To Knee Joint - Superior Medial - Inferior Medial - Middle Genicular Nerves Cutaneous Sural Nerve Muscular

20 Sural Nerve * Descends in the groove between 2 heads of Gastrocnemius by short saphenous nerve. * In the lower 1/3 of the leg, it is joined by the Sural Communicating branch of lateral popliteal nerve * It runs behind & below the lateral malleolus then forward along the lateral border of the foot. * It supplies the skin of the lower 1/3 of the back of the leg & lateral border of the foot & little toe.
