摘要： An angled bone fixation apparatus including a bone screw (11) having a first end portion (12) adapted to be surgically implantable into a patient's vertebral bone mass at first and second spaced apart positions on the bone mass and a second end portion having a head portion (13) with a load transfer surface (14) thereon and a top surface (15). An elongated plate member (30) having upper and lower surfaces angled with respect to each other and an elongated plate slot (36) having a longitudinally extending axis with the slot (36) being surrounded by a peripheral portion having outer opposed edges (32, 34). The plate member (30) has a first and second angled sidewall at the slot with the sidewalls each forming an acute angle with the upper and lower plate surfaces. A washer (20) interfaces with the plate member (30) and the bone screw (11) for distributing load from the bone screw (11) to the plate member (30) with the washer (20) including an opening (26) and upper and lower surfaces with the lower surface having a pair of spaced apart projections (28) extending therefrom. The plate member (30) having a plurality of adjustment openings (49) with each of the washer projections sized and shaped to fit in selected pairs of the adjustment openings.
