Anchor for a synthetic ligament, in particular for a cruciate knee-ligament and process for implantation of a synthetic ligament with such an anchor

摘要

The anchor comprises a holding element, supported in a bone (2), for a terminal section of a ligament (1) arranged in a guide channel (3) formed in the bone (2), and a clamping element that can be braced relative to this terminal section. The holding element is formed by a pin (5) that can be inserted transversely to the pulling direction (Z) of the ligament (1) and is held in a bore (8) which is formed in the bone (2) so as to intersect the guide channel (3) and includes an angle (W) of less than 90@ with a section of the guide channel (3) extending in the pulling direction (Z) of the ligament (1) towards the interior of the bone (2). The pin (5) comprises a passage opening (12) which passes through it perpendicular to its longitudinal axis (B) and is suitable for passage of the ligament (1), and an axial bore (7) which opens into this passage opening and in which the clamping element is held so as to be adjustable perpendicular to the section of the ligament (1) which passes through the passage opening (12). This permits pre-tensioning and fastening of the ligament (1) in simple, separate working steps. IMAGE
