Plate arrangement for osteosynthesis
First Claim
1. A plate arrangement for the osteosynthesis of fractured hollow bones, said plate arrangement comprising:
- two plate parts (10, 12) each of which is connectable to a bone section by means of a plurality of fastening screws (30) and which two plate parts are connected with one another by a telescope arrangement (16, 18) having a telescope axis (24), which telescope arrangement permits an axial movement of the plate parts (10, 12) relative to one another along the telescope axis (24), through passages (28) intended for the passing through of fastening screws (30) being formed in the plate parts (10, 12) in the form of elongated holes, each of said holes having a longitudinal dimension arranged perpendicular to the telescope axis (24).

Abstract
A plate arrangement for the osteosynthesis of fractured tubular bones is made of two plate sections each connectable to associated bone sections or fragments by fastening screws passing through the plate parts. The plate parts are slidable relative to one another by means of a telescope arrangement connecting the two parts, and holes formed in the two parts for attaching the parts to bone sections or fragments are elongated in the direction perpendicular to the telescope axis to allow fastening screws to be inserted at different angles allowing the surgeon some choice in selecting a most favorable position at which to insert each screw into the associated bone fragment. The surface of each plate part facing the bone may be shaped to provide a number of small feet engageable with the bone to provide multiple point contact between the bone and the plate part, and areas of diminished cross section between pairs of adjacent screw holes allow each plate part to be bent by the surgeon on the spot to better adapt the plate to the shape of the involved bone.
