The plate has a first end and a second end where the end which is inserted into the bone has a chamfer and a through hole having a hole axis optionally at an oblique angle to the longitudinal axis of the plate, and which can receive a screw, peg or pin. The second end of the plate includes a locking screw hole and optionally including a compression slot extending in a direction toward a screw hole in the opposing end. Optionally, the non-locking hole has a shroud that forms an arc or portion of a cylinder over the hole. A plate driver having a recess that holds the plate is used to insert the plate into the bone. ## Claims ### Claim 1 A plate for bone fixation comprising: a first end and a second and a longitudinal axis defined between the first end and the second end; a bottom surface configured for contact with a bone; a top surface opposite the bottom surface, wherein a hole extends from the top surface to the bottom surface, the hole having a hole axis less than 90° from the longitudinal axis and configured to receive a head of a screw wherein said hole is shaped to permit the screw to be inserted therethrough with an angle between a screw axis of the screw and the hole axis of up to 20° of conical rotation; and a shroud extending outward from the top surface at an oblique angle and covering at least a portion of the hole, the shroud adapted to be interposed between a tissue and the head of the screw. ### Claim 2 (depends on 1) The plate of claim 1, wherein the plate has an undulating width. ### Claim 3 (depends on 1) The plate of claim 1, further comprising a second hole extending from the top surface to the bottom surface. ### Claim 4 (depends on 1) The plate of claim 1, wherein the hole axis forms an angle of between 10° and 45° with the longitudinal axis. ### Claim 5 (depends on 1) The plate of claim 1, wherein the hole axis forms an angle of between 15° and 40° with the longitudinal axis. ### Claim 6 (depends on 1) The plate of claim 1, wherein the hole axis forms an angle of between 25° and 35° with the longitudinal axis. ### Claim 7 (depends on 1) The plate of claim 1, wherein the first end terminates in a cutting edge. ### Claim 8 A plate for bone fixation comprising: a bottom surface configured for contact with a bone; a top surface opposite the bottom surface, wherein a hole extends from the top surface to the bottom surface and is shaped to permit a screw to be inserted therethrough with an angle between a screw axis of the screw and the hole axis of up to 20° of conical rotation, the hole configured to receive a head of the screw and having a hole axis forming an angle with respect to the bottom surface, and wherein the angle is between 10° and 45°; and a shroud extending outward from the top surface at an oblique angle and covering at least a portion of the hole, the shroud adapted to be interposed between a tissue and the head of the screw. ### Claim 9 (depends on 8) The plate of claim 8, wherein the angle of the hole axis with respect to the bottom surface is between 15° and 40°. ### Claim 10 (depends on 8) The plate of claim 8, the angle of the hole axis with respect to the bottom surface is between 25° and 35°. ### Claim 11 (depends on 8) The plate of claim 8, further comprising a second hole extending from the top surface to the bottom surface. ### Claim 12 (depends on 8) The plate of claim 8, further comprising a cutting edge. ### Claim 13 A plate system for use in associated bone comprising: a non-locking screw having distal threads and a head having a rounded surface without external threads; and a plate having: a first end and a second and a longitudinal axis defined between the first end and the second end; a bottom surface configured for contact with a bone; a top surface opposite the bottom surface, wherein a hole extends from the top surface to the bottom surface, the hole having a hole axis less than 90° from the longitudinal axis and configured to receive a head of the non-locking screw; and a shroud extending outward from the top surface at an oblique angle and covering at least a portion of the hole, the shroud adapted to be interposed between a tissue and the head of the non-locking screw. ### Claim 14 (depends on 13) The plate of claim 13, wherein the plate has an undulating width. ### Claim 15 (depends on 13) The plate of claim 13, wherein the hole is shaped to permit the screw to be inserted therethrough with an angle between a screw axis of the screw and the hole axis of up to 20° of conical rotation. ### Claim 16 (depends on 13) The plate of claim 13, wherein the hole axis forms an angle of between 10° and 45° with the longitudinal axis. ### Claim 17 (depends on 13) The plate of claim 13, wherein the hole axis forms an angle of between 25° and 35° with the longitudinal axis. ### Claim 18 (depends on 13) The plate of claim 13, wherein the first end terminates in a cutting edge.
