What is the pathway of the tibial nerve?

121
Q

L4, L5, S1, S2, S3

A

What is the segmental innervation of the tibial nerve?

122
Q

No, because of its protected position int he popliteal fossa and posterior leg

A

Is the tibial nerve commonly injured?

123
Q

Posterior dislocation

A

What type of dislocation of the knee joint causes damage to the tibial nerve?

124
Q
  • unable to flex toes
  • weakened plantar flexion
  • weakened inversion of the foot

There may be loss of sensation of the posterior aspect of the leg and plantar surface of the foot

A

If the tibial nerve is damaged what can occur?

125
Q

Posterior tibial artery

A

The larger of the 2 terminal branches fo the popliteal artery. It provides the blood supply to the posterior leg compartments and the plantar surface of the foot

126
Q
  • the vessel descends deep to the soleus with tibial nerve and passes behind the medial malleolus
  • as the vessel enters the plantar surface of the foot it divides into the medial and lateral plantar arteries
A

What is the pathway of the posterior tibial artery?

127
Q

Fibular artery

A

Is the larges and most important branch of the posterior tibial artery, it descends along the fibula and supplies the muscles of the deep posterior and lateral leg compartment, as well as giving off a nutrient branch to the fibula.

128
Q

Peripheral Arterial Disease (intermittent Claudication)

A

A condition in which there’s a narrowing or occlusion of the posterior tibial artery and/or its branches
