Patent ID: 8257405

Claim:
A periarticular bone plate for stabilizing a fracture of the proximal tibia, wherein a coronal plane and a transverse plane extend orthogonally relative to each other through the tibia, said bone plate, comprising: a bone plate having, a shaft portion and a head portion unitary with the shaft portion, the shaft and head portions having a bone contacting bottom surface, an opposite top surface, an anterior side, and a posterior side, said head portion defining a first plurality of threaded screw holes configured in a proximal row of at least four screw holes and a distal row of at least three screw holes, wherein said threads of said first plurality of screw holes define respective fixed screw hole axes for said first plurality of screw holes along which said first plurality of screw holes are adapted to secure screws to said plate, and said shaft portion defining a second plurality of screw holes longitudinally displaced relative to a longitudinal axis of said shaft, said first and second plurality of screw holes extending between said top and bottom surfaces for receiving fasteners for attaching said plate to the proximal tibia, said head portion oriented transverse to said shaft portion and extending on only said posterior side of said shaft portion, said shaft portion having a proximal portion and a distal portion that are angled relative to each other at an angle of 168° to 173° , a center of said angle located along said longitudinal axis of said shaft portion and positioned 42 mm to 50 mm from said proximal row in said head portion, and a center of an anteriormost screw hole of said first plurality of screw holes in said head portion being displaced in a posterior direction from said anterior side of said distal portion of said shaft portion by 10 mm to 12 mm such that said center of said anteriormost screw hole is located on a posterior side of said longitudinal axis of said shaft portion, and said head portion having a frontal offset relative to said distal shaft portion by 14 mm to 20 mm; a proximal plurality of screws corresponding to said proximal row of said first plurality of screw holes which extend substantially co-planar with each other and within a first plane parallel to the transverse plane when inserted into said proximal row of said first plurality along said respective screw hole axes, and said proximal plurality of screws including at least two inner screws that extend parallel to each other and two outer screws that extend at divergent angles relative to one another and said inner screws; and a distal plurality of screws corresponding to said distal row of said first plurality of screw holes which extend substantially co-planar with each other and within a second plane parallel to the transverse plane when inserted into said distal row of said first plurality along said respective screw hole axes, and said distal plurality of screws extending at divergent angles relative to one another within said second plane, said first and second planes displaced from each other.
