An anatomically adapted plantar bone plate for fixation of the arthrodesis of the tarsometatarsal I joint in a stable angle, comprising: - a distal plate section, which extends in the longitudinal direction, and in which a distal bore is formed for receiving a bone screw at a stable angle, - a proximal plate section, which extends transversely to the longitudinal direction, and - a central plate section, which extends between the distal plate section and the proximal plate section (2, 3), wherein a plantar bore for receiving a bone screw to be affixed in a plantar position at a stable angle and a bore at a medial angle for receiving a bone screw to be affixed at a stable angle in the medial direction are arranged side-by-side transversely to the longitudinal direction in the proximal plate section, characterized in that the bone plate is adapted to the anatomical conditions in the area of the tarsometatarsal I joint, in that - the bore that is angled medially is formed on a laterally protruding section of the proximal plate section, - the laterally protruding section is inclined towards the bottom side of the plate and is provided with an offset relative to a central section of the proximal plate section, - the central plate section is free of bore holes for screws, - an essentially planar plate section that continues towards the central plate section is formed in the area of the proximal plate section, - the central plate section is formed with a curved plate section with a proximal bending zone that is assigned to the joint gap of the joint to be affixed and that is connected to the essentially planar plate section in the area of the proximal plate section, and - the central plate section is connected to the distal plate section by way of another bending zone or bend, wherein the bending zones (7; 8) are each formed with a thinning of material (5; 6), so that they can be used for additional adaptation of the shape of the bone plate to anatomical conditions, in that predetermined bends are adjustable. - a distal plate section, which extends in the longitudinal direction, and in which a distal bore is formed for receiving a bone screw at a stable angle, - a proximal plate section, which extends transversely to the longitudinal direction, and - a central plate section, which extends between the distal plate section and the proximal plate section (2, 3), - the bore that is angled medially is formed on a laterally protruding section of the proximal plate section, - the laterally protruding section is inclined towards the bottom side of the plate and is provided with an offset relative to a central section of the proximal plate section, - the central plate section is free of bore holes for screws, - an essentially planar plate section that continues towards the central plate section is formed in the area of the proximal plate section, - the central plate section is formed with a curved plate section with a proximal bending zone that is assigned to the joint gap of the joint to be affixed and that is connected to the essentially planar plate section in the area of the proximal plate section, and - the central plate section is connected to the distal plate section by way of another bending zone or bend,
