- Prep area.
- Rotate the leg medially to gain access to the lateral posterior aspect of the foot.
- Inject 5 mls of local anesthetic solution on the lateral side of the foot between the Achilles tendon
and the posterior lateral malleolus.
c. Deep Peroneal Nerve Block (Figure 5-40)
What To Do:
- Assemble equipment.
- Prep area.
- On the dorsal surface of the foot, locate the dorsalis pedis artery and the extensor hallucis longus
tendon (tendon to the great toe). - Insert the needle between the dorsalis pedis a. and the extensor hallucis longus. If a paresthesia of
the great or second toe is obtained, inject 5 mls of local anesthetic solution. - If a paresthesia is not obtained, advance the needle until bone is contacted and inject the 5 mls of
local anesthetic solution in a fan-like manner while withdrawing the needle.
d. Tibial Nerve Block (Figure 5-41)
What To Do:
- Assemble equipment.
- Prep area.
- Rotate the leg laterally to gain access to the medial posterior aspect of the foot.
