A method of removing an intervertebral disc prosthesis from an intervertebral disc space includes the steps of: a) providing a surgical extractor with two legs; b) individually inserting the legs, while the legs are completely detached from each other, into the intervertebral disc space; c) rotating the legs so that they take up a locking position in which a pulling force can be applied by the legs to the intervertebral disc prosthesis; d) connecting the legs to an extraction element; and e) pulling at the extraction element so that the legs apply a pulling force to the intervertebral disc prosthesis.
