Abstract

The invention relates to an arrangement (100, 200, 500) and a method for testing a hold (120, 220, 520), such as an implant, attached to an object (130, 230, 530), such as a bone, the method comprising the steps of: bringing a member (110, 210, 510) into contact with said hold, contactlessly detecting at least one resonance frequency of said member (110, 210, 510) when it is in contact with said hold (120, 220, 510); and interpreting the detected resonance frequency in terms of the degree of attachment of the hold with respect to the object.
