<p>A method of assembly of an attachment device for use in guiding a prosthetic ligament (21) to a required position in a bone tunnel formed in a bone joint (10) between two adjacent bones (11, 12), and to anchor one end of the ligament, said device comprising: an elongate guide element (16) which is manipulatable between a pulling position in which its longitudinal axis extends generally parallel to the pulling direction and an anchoring position in which its longitudinal axis extends transversely of the pulling direction; connecting means (26) provided on the guide element (16) to permit pulling means (22) to be connected to the element in order to pull the guide element, and a trailing implantation system connected thereto, through the bone tunnels with the guide element orientated so that its longitudinal axis extends generally parallel to the pulling direction until the element emerges from the mouth (33) at one end of one of the tunnels, whereby the guide element is manipulatable by the pulling means so as to overlie the mouth and thereby anchor one end of the implantation system; a connecting loop (17) for connection to the guide element (25); connecting apertures (27) formed in the guide element (16) to permit the loop (27) to be connected thereto; in which the loop (27) is made of flexible and implantable material comprising a cohesive assembly of twisted filaments, and is connected to the apertures (27) in the guide element (16) by feeding the loop through the apertures (27) so as to make a U-shaped form with free ends (31) to which the ligament (21) can be connected.</p> |
