The invention describes a femur marrow nail for insertion between the condylii of a knee joint having an anchoring ( ) in the region of the nail tip ( ), having a curvature ( ) extending in the sagittal plane ( ) and having a straight end piece ( ) which has fastening bores ( ) with axes B, C for its fastening. At least two fastening bores ( ) with axes B and C cross the longitudinal axis X of the end piece ( ) at a spacing X , X less than 70 millimeters from the end ( ) of the end piece ( ), and with their axes B and C penetrating a plane ( ) which includes the end ( ) and is perpendicular to the longitudinal axis X at a distance r from the X axis in a region of 10 mm&lE;r&lE;116 mm in order to grip hard bone zones with fastening screws ( ) in the region of the condylii.

Femur marrow nail for insertion at the knee joint

A bone plate for the splinting of a fracture at a bone with a plurality of bone screws. An elastic cushion is provided between the bone screws and the bone plate in the direction towards the fracture. The screw head penetrates through the bone plate completely and lies on the bone with a contact surface under a bias force. A ring body is molded onto the elastic cushion and can be mounted at the lower side of the bone plate. The ring body and the contact surface of the screw head both project beyond the lower side of the bone plate.
