    18 ABSTRACT The present invention relates to a an attachment device for attaching aprosthesis to a bone, comprising: a base plate having an extension in an xy-plane; a first holder for holding a first abutment; a second holder for holding asecond abutment; a locking plate attached to the base plate to restrictmovement of the holders in a z-direction away from the base plate. Thelocking plate is configured to allow rotation of the first and second holderaround a z-axis perpendicular to the xy-plane. The locking plate and the baseplate is configured to allow movement of the first holder along the x-directionand to prevent movement the y-direction and to prevent movement of thesecond holder in the x- and y-direction. At least one flexible member isarranged between each of the first and second holders and the base plate,the flexible member being flexible in the z-direction to allow movement of thefirst and second holder in the z-direction and to allow the first and secondholder to tilt with respect to the xy-plane.

    that the attachment device 100 acts as an intermediate element allowing aprosthesis to be attached to an arm.
    The attachment device further comprises a Iocking element 114 whichis configured to be connected to the base plate by means of screws 116through openings 118 in the base plate and corresponding openings 120 inthe Iocking element 114. Even though the Iocking element 114 is illustratedherein to consist of two separate parts, the Iocking element 114 may equallywell be a single part or comprise a plurality of parts. A suitable Iockingelement may also be formed as an integral part of the base plate 102.
    A functional feature of the Iocking element 114 is that it is configured torestrict movement of the holders 106, 108 in a z-direction away from the baseplate 102. ln other words, the Iocking element 114 locks the first and secondholder 106, 108 to the base plate 102, preventing them from coming off.Moreover, the Iocking element 114 is further configured to allow rotation ofthe first and second holder 106, 108 around their respective z-axis,perpendicular to the xy-plane. The Iocking element 114 and the base plate102 is further configured to allow movement of the first holder 106 along thex-direction of the base plate and to prevent movement of the first holder 106in the y-direction, and to prevent movement of the second holder 108 in boththe x-direction and the y-direction. For the first holder 106, the movement inthe x-direction is allowed since the distance between a side wall 104b of thebase plate 102 and a dividing wall 122 is larger than a diameter of the lowerportion 124 of the holder 106. The maximum, allowable movement of the firstholder in the x-direction is thus limited by the side wall 104b and the dividingwall 122. ln a similar manner, any movement in the xy-plane of the secondholder 108 is prevented by the side walls 104a,d,c of the base plate 102 andthe dividing wall 122. The skilled person readily realizes that the wall limitingthe movement of the holders may be arranged and configured in manydifferent ways. One or more of the walls may for example be part of theIocking element 114 while still providing the desired functionality.
    Moreover, the attachment device 100 comprises two flexible members126, 128, arranged between each of the first and second holders 106, 108
