Abstract
A bone plate includes a first through hole extending through the plate along a first longitudinal axis from a proximal surface of the plate to a bone-facing distal surface thereof which, when the plate is placed on a target portion of bone in a desired orientation, faces the bone. An outer wall of the first through hole includes three wall sections provided with projections for receiving a screw head of a bone screw. The three wall sections are straight or convex.
Claims35
A kit for bone fixation, comprising:
- a through hole extending through a bone plate along a longitudinal axis from a proximal surface to a bone-oriented distal surface which, when the bone plate is positioned on a bone in a desired orientation, faces the bone, an outer wall of the through hole having three non-concave wall sections provided with projections for lockingly engaging a head of a bone screw inserted therethrough and at least one peripheral hole, each peripheral hole overlapping part of the through hole;
- a central bone screw configured to be inserted through the through hole, the central bone screw including a threaded head sized and shaped to lockingly engage the projections in the through hole;
- and
- at least one peripheral bone screw, each peripheral bone screw being sized and shaped to be inserted through a corresponding peripheral hole.

A kit for bone fixation, comprising:
- a bone plate comprising a through hole extending therethrough from a first surface which, in an operative configuration, faces toward a bone, to a second surface which, in the operative configuration, faces away from the bone, the through hole extending through the bone plate and defined via a wall including at least three non-concave sections, at least portions of the non-concave sections including threading and at least one peripheral hole formed between a first one and a second one of the non-concave sections;
- and
- a central bone screw configured to be inserted through the through hole, the central bone screw including a threaded head sized and shaped to lockingly engage the threading of the non-concave sections.
