A bone anchor (1, 101, 201, 301, 401), comprises:
a main body (2, 102, 202, 402) defining a longitudinal axis (21) and comprising a head (6, 106, 206, 406);
at least one insertion hole (3, 103, 203, 403), which extends from a first opening (31, 131, 231, 431) formed in the head (6, 106, 206, 406) to a second opening (32, 132, 232, 432) formed in the main body (22, 102, 202, 402),
wherein the at least one insertion hole (3, 103, 203, 403) has an axis (33, 133, 233, 432) which is arranged to be inclined with respect to the longitudinal axis (21) of the main body (2, 102, 202, 402) at an angle (±), and wherein the insertion hole (3, 103, 203, 403) is further configured to receive and guide therethrough a pin-shaped element (4) to be anchored within a bone (1000) or bone fragment;
a locking device (5, 105, 205, 305) configured to lock the position of the pin-shaped element (4) inserted within the at least one insertion hole (3, 103, 203, 403) in an axial direction. |
