A bone plate includes at least one variable angle locking hole that is configured to threadedly mate with a variable angle locking screw oriented so as to define any angle among a range of angles with respect to a central axis of the VA locking hole at which a threaded head of the locking screw is configured to threadedly purchase with the bone plate in the variable angle locking hole.

Bone plate with form-fitting variable-angle locking hole

A bone plate includes locking holes that reconfigured to threadedly mate with locking screws to fix the bone plate to an underlying bone. Some of the locking holes are standard-type locking holes. Alternatively or additionally, some of the locking holes are variable-angle locking holes. The bone plate defines a collection cavity in the locking holes that are configured to collect shavings that can be produced if the bone screw is cross threaded in the locking hole.

Implant having locking holes with collection cavity for shavings

A bone plate includes an upper surface, an opposed lower surface configured to face a bone, and at least one aperture extending through the bone plate from the upper to the lower surface along a central aperture axis. The aperture is defined by an interior surface of the bone plate. The interior surface defines a plurality of columns sequentially located about a circumference of the interior surface and a plurality of recesses located circumferentially between the columns. Each of the columns is configured to undergo deformation at least in a radial direction perpendicular to the central aperture axis responsive to engagement with a head of a locking bone screw that is receivable within the at least one aperture so as to lock the head to the bone plate. The plurality of columns comprises at least five columns.
