Osteosynthesis plate for smaller bones e.g. carpel bones, has central hole with diameter adjusted to that of positioning pin for engaging running plate on pin, and landmark situated at level of plate periphery

摘要

The plate has lateral holes for fixing a screw (6) for its fixation to small neighboring carpel bones (2 to 5). A central hole has its diameter adjusted to that of a positioning pin, for permitting the engagement of a running plate (1) on the positioning pin. The pin is fixed in one of the bones or between the bones to be healed. A landmark (18) is situated at a level of plate periphery. An Independent claim is also included for an instrument set for fixing an osteosynthesis plate.
