1 Sole Of The Foot Dr. Rakesh Kumar Verma Assistant Professor Department of Anatomy KGMU UP Lucknow

2 SKIN Thick Nerve Supply

3 Skin Thick and hairless.Firmly bound down to the underlying deep fascia by numerous fibrous bands. Shows a few flexure creases at the sites of skin movement. Sweat glands are present in large numbers. The sensory nerve supply to the skin of the sole of the foot

4 SUPERFICIAL FASCIA Cutaneous Nerves Cutaneus Arteries

5 CUTANEOUS NERVES Medial calcaneal branch of the tibial nerve Medial plantar nerve Lateral plantar nerve Sural & saphenous nerve

6 DEEP FASCIA Planter Aponeurosis Deep transverse metatarsal Ligament Fibrous flexor sheath Septae

7 Plantar aponeurosis Definition: Thickened band of deep fascia in the sole of the foot. Attachment: Posteriorly: Medial tubercle of calcaneus. Anteriorly: Divides into 5 slips which pass to the 5 toes. On each side: Attached to the metatarsal bones by medial and lateral intermuscular septa.

8 Plantar aponeurosis Functions: Protects the underlying nerves and vessels. Maintains the longitudinal arches of the foot.

25 NERVES MEDIAL PLANTER LATERAL PLANTER

26 Medial Plantar Nerve It is larger of the two terminal branch of the posterior tibial nerve. Enter the foot midway between the medial malleolus and the medial tubercle of the calcaneus, under cover the flexor retinaculum. Passes forwards deep to the abductor hallucis muscle. Terminate at the bases of the metatarsal bones by dividing into 3 planter digital nerves.

27 Medial Plantar Nerve Branches: Muscular (to four muscles) to: Abductor hallucis. 1)Flexor digitorum brevis. 2)Flexor hallucis brevis 3)First lumbrical muscle Cutaneous: Planter cutaneous branches: 1)To the skin of the medial 2/3 of the sole of the foot. 2)Planter digital nerves Articular branches: To intertarsal and tarso- metatarsal joints.

28 Lateral Plantar Nerve It is smaller of the two terminal branches of the posterior tibial nerve. Enters the foot midway between the medial malleolus and the medial tubercle of the calcaneus under cover the flexor retinaculum. Passes forwards and laterally deep to abductor hallusis. Terminate a t the base of the 5 th metatarsal bone, by dividing into a superficial and a deep branches.

29 Lateral Plantar Nerve Branches: Muscular : 1)Flexor digitoum accessorius muscle 2)Abductor digiti minimi 3)Flexor digiti minimi brevis 4)Adductor halucis muscle. 5)Interossei 6)2 nd, 3 rd & 4 th lumbricals. Cutaneous: 1)Skin of the lat. 1/3 of the sole 2)Skin on the lat.side of the planter surface of the little toe and the adjoining sides of the 4 th & 5 th toes. 3)The planter digital branches, also, supply the skin on the dorsum of the terminal phalanges of the lateral one and half toes.

33 Medial Plantar Artery One of the two terminal branches of the posterior tibial artery. Enter the foot midway between the medial malleolus and the medial tubercle of the calcaneus, under cover the flexor retinaculum. Passes forwards deep to the abductor hallucis muscle. Passes b/w the abd.hallucis and flexor digitorum brevis.

34 Medial Plantar Artery Termination: By anastmosing with the 1 st planter metatarsal artery. Branches: Muscular Digital: 3 superficial digital branches these branches end by anastmosing with the first, second and third planter metatarsal arteries.

35 Lateral Plantar Artery One of the two terminal branches of the posterior tibial artery. At first between the 1 st and 2 nd layers, then curves medially between the 3 rd and 4 th layers of the sole. Turns medially with the deep branch of the lateral planter nerve with slight forward convexity to from the plantar arch between the 3 rd & 4 th layers of muscles.

36 Lateral Plantar Artery Branches: Muscular Anastomotic branches: b/w arcuate & lateral tarsal arteries of the dorsalis pedis artery. Posterior perforating arteries: 3 branches which anastomose with the dorsal metatarsal arteries. Planter digital artery: to the lateral side of the little toe. Three planter metatarsal arteries
