Abstract:
1. Locking mechanism for a broken or fractured bone, comprising: a medulla nail with a proximal portion and a distal portion, and at least one locking aid, wherein the distal portion has an outer surface structure which is designed so that the bone can be stabilised by means of the medulla nail due to the at least one locking aid configured to extend through the bone to be in contact with at least a portion of the outer surface structure of the medulla nail, thereby preventing the medulla nail from being rotated or subjected to axial stress; wherein the medulla nail has a longitudinally extending shape; wherein the outer surface structure has grooves distributed around the external circumference of the outer surface structure, the grooves extending parallel with the longitudinal extension of the medulla nail; and wherein the at least one locking aid contacts at least one groove of the outer surface structure of the distal portion, without extending through the medulla nail, to thereby prevent the medulla nail from being rotated or subjected to axial stress.
