Disclosed are examples of a patella bone plate. In some examples, the patella bone plates may include a contoured body with a longitudinal axis, and with a radius of curvature, a plurality of contoured arms and extending superiorly from the contoured body, the plurality of contoured arms spaced apart from the longitudinal axis, the plurality of contoured arms, a plurality of holes, a hook, the hook having a radius of curvature configured to allow the hook to extend around an apex of the patella, a hole located on the hook, the hole defining a distal fixation screw path that is substantially parallel to and offset from the longitudinal axis. In various examples, the contoured body may have a single arm with a staggered hole arrangement. The plurality of holes may include variable angle holes, locking holes, fixation holes, slots, or a combination thereof.

An orthopedic implant including an outer surface and at least one opening extending through the outer surface for receiving a fastener for coupling the implant to a patient's bone or bone portion / fragment. The opening including a plurality of fins circumferentially disposed about the opening for engaging threads formed on a head portion of the fastener to secure the fastener to the implant. The plurality of fins being arranged and configured in first and second vertically spaced rows of fins. At least one of the fins including a different configuration, property, etc. relative to at least one of the other plurality of fins. In one embodiment, each of the first and second fins in a vertically stacked relationship includes a different configuration from the other of the first and second fins in that stack. In one embodiment, the different configuration includes a different length, a different thickness, or a combination thereof.

An internal plate for treating a fracture along a clavicle, the internal plate comprising: a plate body comprising a longitudinal component extending from a first end to a second end and an extension portion extending from the second end, the second end configured to be mounted over an internal lateral head, a first set of variable angle holes extending through a portion of the longitudinal component including the second end of the longitudinal component and the extension portion, each variable angle hole of the first set of variable angle holes extending through the plate body along a central axis such that a bone screw can be inserted through the variable angle hole at a user-selected angle relative to the central axis; and a plurality of combination holes extending through the longitudinal component, each combination hole of the plurality of combination holes comprising a first portion configured to receive a bone screw at a user-selected angle and a second portion configured to receive a compression screw.

The utility model relates to the technical field of cutting tools, and discloses a variable-angle ceramic cutting tool which comprises a tool handle, an adjusting circular truncated cone is fixedly connected to the right end of the tool handle, an adjusting disc is arranged above the adjusting circular truncated cone, a connecting unit is arranged on the outer side of the adjusting disc, and a mounting block is fixedly connected to the surface of the right side of the adjusting disc. A blade is detachably connected to the right side of the mounting block, an annular adjusting tooth set is fixedly connected to the upper surface of the adjusting circular truncated cone, an annular tooth groove set is formed in the bottom face of the adjusting disc, and a protective cover is fixedly connected to the outer side of the adjusting disc. According to the utility model, through the cooperation of the connecting unit, the annular adjusting tooth group and the annular tooth groove group, the angle, equivalent to the knife handle, of the blade can be rapidly adjusted, and meanwhile, through the cooperation of the protective cover, the annular groove, the annular air bag, the annular plate and the push rod, after the adjustment is completed, the knife handle can be rapidly adjusted. And the outer side of the annular adjusting tooth group is completely sealed and protected.

The present invention relates to an embodiment that includes a bone fixation system comprising: a bone anchor with a tapered head, the head being threaded; and a plate that includes a recess, the recess being a reamed or countersunk hole; wherein: (a) no part of the recess is threaded; (b) the recess includes an inner wall; (c) the inner wall includes reliefs along its perimeter. Other embodiments are described herein.

Apparatus and methods are disclosed for correcting deformities in a patient's foot. In one example, a metatarsus adductus is addressed using a pin placement guide that is angulated to be placed in alignment with a cuneiform and a metatarsal, such that the TMT joint can be subsequently cut, and the metatarsal moved into proper alignment. Th pin placement guide can be a variable angle guide, or a kit of fixed-angle pin placement guides can be provided.

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.
