Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The adductor canal block targets the saphenous nerve and, through its spread in the adductor canal, the posterior branch of obturator nerve and the vastus medialis nerve. However these nerves can't fully explain this block's efficiency.
It has been shown that local anesthetic can spread in the adductor canal to the tibial and fibular nerves through the adductor hiatus. However, this spread is inconstant, and no study has evaluated the frequency of this spread yet.
The main objective of this study is to assess the diffusion's frequency of adductor canal block to fibular and tibial nerves through ultrasound observation at the popliteal fossa.
