Claims126
A skeletal plating system for aligning and maintaining bone portions of the same bone or of different bones in a selected spatial relationship for healing or fusion of the bone portions, comprising a plate having a length sufficient to span at least two bone portions, said plate having an upper surface and a lower surface for placement against the bone portions, said plate having a thickness as measured from said upper surface to said lower surface, said plate having a plurality of bone screw receiving holes extending through said plate from said upper to lower surface, at least a first of said plurality of bone screw receiving holes associated with a first of the bone portions and at least a second of the said plurality of bone screw receiving holes associated with a second of the bone portions, said plate having at least one malleable segmentation zone in which said plate may be separated by bending at the time of use by a surgeon into at least first and second segments, said segmentation zone including a reduction of said thickness of said plate along which said plate can be separated into said first and second segments, each of said first and second segments having edges suitable for surgical implantation formed when separated at said segmentation zone, said first segment comprising at least said first and said second of said plurality of bone screw receiving holes and said a single locking element associated with a single bone screw receiving hole for second segment comprising at least two of said plurality of bone screw receiving holes.
A skeletal plate for aligning and maintaining bone portions of the same bone or of different bones in a selected spatial relationship for healing or fusion of the bone portions, said skeletal plate comprising:
- a mid-longitudinal axis, a length sufficient to span at least two bone portions, and a width transverse to the length, said plate having an upper surface and a lower surface for placement against the bone portions;
- a plurality of bone screw receiving holes extending through said plate from said upper surface to said lower surface, each of said bone screw receiving holes having a central longitudinal axis;
- and
- at least one segmentation zone configured to sever said plate into a plurality of segments along a predetermined path across the width of said plate, said predetermined path being non-linear.
A skeletal plate for aligning and maintaining bone portions of the same bone or of different bones in a selected spatial relationship for healing or fusion of the bone portions, said skeletal plate comprising:
- a mid-longitudinal axis, a length sufficient to span at least two bone portions, and a width transverse to the length, said plate having an upper surface and a lower surface for placement against the bone portions;
- a plurality of bone screw receiving holes extending through said plate from said upper surface to said lower surface, each of said bone screw receiving holes having a central longitudinal axis;
- and
- a plurality of segmentation zones, said segmentation zones each being configured to permit said plate to be separated along a predetermined path across the width of said plate to form at least two plate segments, a first of the segmentation zones being positioned between two adjacent bone screw receiving holes, at least a second segmentation zone being positioned between said first segmentation zone and at least one of said adjacent bone screw receiving holes.
A skeletal plate for aligning and maintaining bone portions of the same bone or of different bones in a selected spatial relationship for healing or fusion of the bone portions, said skeletal plate comprising:
- a mid-longitudinal axis, a length sufficient to span at least two bone portions, and a width transverse to the length, said plate having an upper surface and a lower surface for placement against the bone protions;
- a plurality of bone screw receiving holes extending through said plate from said upper surface to said lower surface, each of said bone screw receiving holes having a central longitudinal axis and a minimum dimension as measured transverse to the central longitudinal axis;
- and
- at least one segmentation zone pre-configured to sever said plate into a plurality of segments along a predetermined path, said at least one segmentation zone extending a distance across the width of said plate greater than the minimum dimension of one of said bone screw receiving holes, wherein said predetermined path is at least in part curved.
A method for aligning and maintaining bone portions of the same bone or of different bones in a selected spatial relationship for healing or fusion of the bone portions, said method comprising:
- providing a plate including a mid-longitudinal aixs, a width transverse to the mid-longitudinal axis, and a plurality of bone screw receiving holes;
- bending a first portion of the plate relative to a second portion of the plate in a first direction along a pre-configured separation path;
- bending the first and second portions in a second direction opposite to the first direction to separate the first and second plate portions apart along a predetermined separation path;
- placing one of the separated first and second plate portions against at least two of the bone portions;
- inserting a bone screw into one of the bone screw receiving holes to secure one of the plate portions against at least one of the bone portions;
- and
- locking the bone screw to the plate portion.
A method for aligning and maintaining bone portions of the same bone or of different bones in a selected spatial relationship for healing or fusion of the bone portions, said method comprising:
- providing a plate including a mid-longitudinal axis, a width transverse to the mid-longitudinal axis, and a plurality of bone screw receiving holes;
- moving a first portion of the plate relative to second portion of the plate of separate the first and second plate portions apart along a pre-configured frangible separation path, each of the first and second plate portions including at least one of the bone-screw receiving holes;
- placing one of the separated plate portions against at least two of the bone portions;
- and
- inserting a bone screw into one of the bone screw receiving holes to secure one of the plate portions against one of the bone portions.
