Device for reconnecting a broken bone
First Claim
1. Device for connecting a fractured bone, such as the femoral neck area, comprising a bone fastening cover plate with fastening perforations, said cover plate having a longitudinal direction extending parallel to the longitudinal axis of a bone to which it is to be connected by fastening means a sleeve carried by and positioned at an angle relative to the bone fastening member and a trochanter supporting plate, wherein the trochanter supporting plate (20) is detachably connectable to the bone fastening cover plate (11) and comprises an elongated plate-shaped section (29) corresponding approximately to and elongated in the longitudinal direction of the bone fastening cover plate (11), said plate shaped section has a web (24), one end (24a) of said web passes into a plate-shaped section (25) extending in the elongated direction and forming a trochanter supporting surface, the web (24) has two sides extending in the elongated direction with a reinforcing leg (22, 23) extending along each side for at least a partial length of the elongated web (24) and into a portion of the section (25), toward a terminal area (25a) of the section spaced from the web, and in the direction toward the terminal area (25a), runs out tapering conically, the bone fastening cover plate (11) of the device (10) is positionable between the two legs (22, 23) and is arranged to rest against the web (24) so that the section (25) forming the trochanter supporting surface projects in the elongated direction from the bone fastening cover plate (11) and an ovaloid perforation (27) for the passing through of the bone fastening member reception sleeve (13).

Abstract
The device for connecting a fractured bone in the femoral neck is of two-piece construction that includes a bone fastening cover plate (11) and a trochanter supporting plate (20), in which the bone fastening cover plate (11) is provided with a bone screw reception sleeve (13) assuming an angle which, below the trochanter supporting surface, is passed through a cover plate-like section connected with the trochanter supporting plate (20) which bears upon the bone fastening cover plate (11) which, as well as the cover plate-like section are provided with a number of fastening screw perforations (12) which can be brought into coincidence, in which the trochanter supporting surface is so configured as to correspond to the shape of the trochanter so that, on account of the two-piece construction, an improved adaptability to anatomical conditions by an arbitrary combination of the individual components is possible.
