Patent ID: 8753343

Claim:
A bone fixing device comprising: an intramedullary nail with a distal end part, a proximal end part, a center line and a bore extending in the proximal end part across and transverse to the center line, provided with a bore axis; and a bone plate with a top side, a bottom side destined for bone contact, a central continuous opening set up in a central section of the bone plate and connecting the top side with the bottom side and several plate holes, peripherally arranged around the central opening and also continuous, wherein at least one nail-side clamping surface is conformed at the proximal end part of the intramedullary nail, the bone plate is provided with at least one plate-side clamping face corresponding to the nail-side clamping surface such that the two clamping surfaces corresponding to each other are displaceable and rotatable against each other in an unclamped condition, and fixed to each other such that areal surface portions of each clamping surface are in contact with each other in a clamped condition, and the center line intersects the nail-side clamping surface under an average angle of 1° to 20°.
