    Abstract: A plug system (10', 10, 10") for preventing material from extruding beyond a desired location in a bone tunnel (42) includes a plug member (20', 20, 22") that has an insertion axis (2, 4, 206') extending from a first end (202', 202, 202") and a plurality of interleaving arms (205', 205, 205") disposed about the insertion axis. The arms (205', 205, 205") are affixed at a second end (204', 204, 204") and are flarable at the first end (202', 202, 202") between an insertion position wherein the arms (205', 205, 205") are relatively close packed and a position wherein the arms (205', 205, 205") are flared. A portion of each arm (205', 205, 205") remains in overlapping relation to an adjacent arm (205', 205, 205"). The system (10', 10, 10") further includes an expansion member (32, 30, 31) that has an insertion portion (321, 301, 311) adapted to separate the arms (205', 205, 205") upon progressive entry along the insertion axis (2, 4, 206') from the first end m(202'. 202. 202"). In use the plug (20', 20, 20") can be inserted either first end (202', 202, 202") first, with the expansion member (32, 30, 31) drawn into the plug (20', 20, 20") by a manipulator (33, 50), or second end (204', 204, 204") first, with the expansion member (32, 30, 31) driven along the insertion axis (2, 4, 206').

    Abstract: Locking plug (1) consisting of two coaxial parts (2, 3) separated by a break start line, mutually coaxial recesses (2, 3) being formed within each part. The first part (1) enables the second part (3) having a thread (5) to be screwed into an implant where it remains fixed after the two parts are separated at line (4), after a predetermined rupture torque is exceeded. Advantageously, the recess (7) in the second part (3) provides for subsequent release, if required, so that the instrument can be removed. A clamping action is obtainable with great precision, in accordance with the requirements of the manufacturer, since the rupture torque can be adjusted to a specified value by precise machining of the break start line (4).
