Abstract
The neurologic consequences of an intraneural needle insertion and injection of local anesthetic depend on many factors, such as the design of the needle tip, the injection force, and the chemical structure and concentration of the injectate. However, the anatomic specifics of a given nerve and how its organization can protect it against external injury may be the most significant factor determining the likelihood of injury. Finally, any preexisting pathology of the peripheral nerve also contributes to the risk of postblock neurologic symptoms.
