Evaluation of Local Anesthetic Diffusion to the Sciatic Nerve During Adductor Canal Block

Recruiting now

Conditions studied: Sciatic Nerve, Adductor Canal Syndrome

In brief

Adductor canal block is an effective analgesic technique for major knee surgery. However, the saphenous nerve block is not sufficient to explain this block's efficiency. It has been shown that adductor canal block can spread to the tibial and fibular nerves through the adductor hiatus. However, this diffusion's frequency has never been measured. The main objective of this study is to assess clinically the frequency of the spread of the adductor canal block to the fibular and tibial nerves.
