An improved posterior acetabular wall fracture buttress plate has a main plate and a plate extension. The buttress plate has a pair of arms extending from the main plate and an arm extending from the plate extension. The main plate and the plate extension are pre-contoured with a concavity contoured and bent lengthwise off horizontal relative to the main plate to mimic a hip socket contour posteriorly along an undersurface at about 38 degrees plus or minus 8 degrees to mimic a curvature of the hip to yield an angle on the undersurface of 142 degrees plus or minus 8 degrees. The arms are 1.0 cm or less wide. The plate extension extends from the main plate and has at least one transverse groove defining a breakaway section allowing the plate extension to be removed from the main plate.
