About this trial

This study uses MRI imaging to evaluate the spread of local anesthetic following the administration of a pericapsular nerve group (PENG) block. The goal is to determine whether a distinct fascial plane exists between neurovascular structures, potentially explaining the block's observed clinical effectiveness.

Trial outcomes

Primary outcomes

Extent of local anesthetic spread as visualized on MRI after PENG block administration

MRI images will be used to assess the diffusion pattern of local anesthetic following PENG (Pericapsular Nerve Group) block. The assessment will focus on whether the anesthetic reaches a specific fascial plane between the femoral vessels and nerves. A radiologist will evaluate the extent and location of the anesthetic spread in relation to key anatomical landmarks (according to centimeter-based measurements as per MRI protocols).
