Abstract
The body (4) of the hook (1) has a passage (6) for receiving a transverse bar, which passage terminates in an aperture (7) and extends throughout the length of the body. The hook (1) includes a curved strip portion (5) for retaining an osteosynthesis rod which is connected to the body (4) in a region of said aperture (7). The height of the aperture (7) exceeds the thickness of the bar. The strip portion (5) has a width substantially equal to the width of the body (4) and edge portions (9) of the passage (6) are so shaped as to define sliding ramps for the rod which are inclined toward the interior of the strip portion (5). The arrangement of the hook ensures a trapping of the rod which improves the safety of the device in use and reduces the overall size of the hook.
