An osteosynthesis fixation system, comprising: a plate defining a central opening and adapted for affixing between a first bone and a second bone, the plate being configurable between an open shape and a compressed shape, the plate being fabricated from a shape memory material or an elastic material capable of deforming and rebounding to an original shape; and an insertion tool adapted for insertion into the central opening and abutment with the plate to retain the plate in its open shape once the plate has been moved to its open shape, wherein the insertion tool allows locating of the plate for affixing with the first bone and the second bone, further wherein release of the plate from the insertion tool after affixation of the plate with the first bone and the second bone allows the plate to move from its open shape to its compressed shape, thereby compressing the first bone with the second bone, wherein the plate is pre-loaded on the insertion tool, wherein the plate, comprises: a first end portion defining a first screw hole; a second end portion defining a second screw hole; and first and second arms (13, 14) disposed between the first and second end portions (16, 17), wherein the first and second end portions (16, 17) and the first and second arms (13, 14) define the central opening, further wherein the first and second arms (13, 14) expand to configure the plate in its open shape and contract to configure the plate in its compressed shape, and wherein the insertion tool comprises a retention spacer that inserts into the central opening of the plate when the plate is in its open shape such that the retention spacer abuts the first and second end portions (16, 17) of the plate to retain the plate in its open shape, wherein the retention spacer preferably comprises raised side portions that abut the first and second end portions (16, 17) of the plate to retain the plate in its open shape, characterized in that the insertion tool comprises a platform including a first guide hole that aligns with the first screw hole and a second guide hole that aligns with the second screw hole when the plate is in its open shape. a plate defining a central opening and adapted for affixing between a first bone and a second bone, the plate being configurable between an open shape and a compressed shape, the plate being fabricated from a shape memory material or an elastic material capable of deforming and rebounding to an original shape;
