Ultrasound guided versus Landmark guided Ankle block and sono-anatomical correlation of ankle nerves with landmarks- Prospective randomized single blind study

This study is randomized, single blind, parallel group, single center trial will include 60 participants who are scheduled for elective foot surgeries under ankle block, will be randomized into two groups of 30 each where Group L will receive ankle block by landmark technique and Group U will receive ankle block under ultrasound guidance both these techniques are well established practice of ankle block. The primary outcome of this study to evaluate the effectiveness of these techniques in terms of Ease of performance, duration required, block success, analgesic requirement, total duration of analgesia, patient satisfaction feedback. the secondary objective of this study is to analyze the sono-anatomical correlation of Tibial nerve, saphenous nerve, superficial and deep peroneal nerve and sural nerve by proximal tracing of the these nerves by ultrasonography from fixed landmark points.
