A pin is insertable into the passage from the end having the head to expand the body transversely to anchor it in the hole. The body and pin are of biocompatible material and the body contains carbon fibres embedded in and extending longitudinally along its interior. The invention provides also a surgical implant kit including the stud, and a method of surgery employing the stud and kit.
