Paragraph Number

63

The radial grooves 116 of each arm 114 may be similarly shaped to mate with the raised ridges 216 on the head 210 of the corresponding screw 104 such that the clockwise rotation of the screw 104 (corresponding to tightening of the screw 104 within the bone 102) is permitted, while counterclockwise rotation of the screw 104 (corresponding to loosening of the screw 104 within the bone 102) is not permitted while the rotatable structure 112 is in the locked orientation. Thus, the engagement of the arms 114 with the heads 210 of the screws 104 may prevent the screws 104 from rotating in a manner that would loosen them relative to the bones 102 in which they reside.
