A fracture fixation plate assembly comprising: an elongated body defining a first longitudinal axis and including a proximal end, a distal end, a bone contacting surface, an opposite surface, at least one anchoring slot extending from said bone contacting surface to said opposite surface and a pivot hole at said distal end; a hinge, including a proximal end and a distal end, the proximal end pivotally engaged with the distal end of said elongated body defining a first pivot axis through said pivot hole transverse to said first longitudinal axis and the distal end of the hinge including a substantially cylindrical barrel, said barrel defining a second pivot axis transverse to both said longitudinal axis and said first pivot axis; said hinge having an unlocked state and a locked state; a setting fastener, adapted for insertion along said first pivot axis of said hinge and into said pivot hole of said elongated body, wherein when said setting fastener is loose, said hinge remains in an unlocked state and when said setting fastener is tightened said hinge remains in a locked state; an axle adapted to be received by the cylindrical barrel of said hinge, having a lateral end, a medial end, and a middle portion defining an axle axis, the middle portion pivotally engaged with said barrel of said hinge, said axle axis collinear with said second pivot axis and at least one of said lateral and medial ends (402, 404) extending out from said barrel of said hinge; and at least one head (500, 550) having a bone contacting surface (506, 556) and an opposite surface (508, 558), said at least one head (500, 550) rigidly engaged to said lateral and/or medial ends (402, 404) of said axle, and said at least one head (500, 550) having at least one hole (510, 560) adapted to receive a bone fastener, said at least one hole (510, 560) extending from said bone contacting surface (506, 556) to said opposite surface (508, 558); wherein said elongated body, hinge, setting fastener, axle and at least one head (500, 550) are separate components; wherein, in the unlocked state, said hinge is adapted to pivot laterally/medially with respect to said elongated body around said first pivot axis; wherein, in the unlocked state, said axle is adapted to displace laterally/medially along said second pivot axis and to rotate in said cylindrical barrel about said second pivot axis; wherein, in the locked state, said hinge is impeded from pivoting with respect to said elongated body; and wherein, in the locked state, said axle is impeded from displacing along, and rotating about, said second pivot axis. an elongated body defining a first longitudinal axis and including a proximal end, a distal end, a bone contacting surface, an opposite surface, at least one anchoring slot extending from said bone contacting surface to said opposite surface and a pivot hole at said distal end;
