The purpose of this study is to observe or not a reduction on pain and anxiety felt by the patient when performing an ultrasound-controlled ankle block in preparation for forefoot surgery, using a virtual reality device instead of drug sedation.

Currently, in preparation for forefoot surgery, the realization of the ankle block is accompanied by drug sedation.

The investigator's randomized study aims to compare the anxiety and pain experienced by patients who have benefited from drug sedation with those of patients who benefited from the virtual reality device at the time of the realization of the ankle block.
