Deep dives
Ankle Block
An ankle block is a regional anesthetic technique used for foot operations. It is technically easy, highly safe, and has minimal side effects. Ankle blocks target the five peripheral nerves that provide sensory innervation to the foot: the sural, deep peroneal, superficial peroneal, posterior tibial, and saphenous nerves. The cutaneous innervation of the foot, as well as indications, contraindications, and alternatives to ankle blocks, are common test questions.
