A variable angle locking implant includes a bone plate having a lower surface, an upper surface, and at least one opening extending from the lower surface to the upper surface along an axis. The opening has a plurality of fins oriented along a plane. The axis is non-perpendicular to a tangent of a projection of the lower surface across the opening, the tangent defined at the intersection between the axis and the projected lower surface, and/or the plane is non-parallel to the tangent. The implant includes at least one fastener, and the plurality of fins are deflectable relative to a head portion of the fastener such that the fastener can be inserted and retained at any one of a plurality of angles.

Variable angle locking implant

A multi-layer, fiber-reinforced composite orthopaedic fixation device having a design selected based on a desired characteristic of the orthopaedic fixation device. The design may be selected according to a model of the device, the model defining design constraints, and the design may comprise a pattern of the fiber angle for each layer. The selection of a design may be analyzed using finite element analysis to determine whether the design will comprise the desired characteristic.

Composite internal fixators

A multi-layer, fiber-reinforced composite orthopedic fixation device having a design selected based on a desired characteristic of the orthopedic fixation device. The design may be selected according to a model of the device, the model defining design constraints, and the design may comprise a pattern of the fiber angle for each layer. The selection of a design may be analyzed using finite element analysis to determine whether the design will comprise the desired characteristic.

A method for targeting a landmark of an orthopaedic implant comprises implanting the orthopaedic implant in a body. The orthopaedic implant having at least one landmark defining two or more locations for targeting and a first magnetic sensor located at a known distance from at least one of the two or more locations. The method includes comprises identifying one of the locations using a landmark identifier, the landmark identifier having at least one of a second magnetic sensor and a magnetic field generator, installing a transfixion element in the at least one landmark, and identifying a second location using the landmark identifier.

A bone plate system for fixation of bone includes a bone plate and a first fastener. The bone plate includes a bone contacting surface, an upper surface, and a first opening extending between the bone contacting surface and the upper surface. The first opening includes a lower portion, a non-threaded upper portion, and a threaded portion. The threaded portion includes threads and converges towards the lower portion. The lower portion includes a smallest diameter of the first opening. The first fastener includes a head at least partially comprising a spherical portion and a first material. When the first fastener is inserted into the first opening, the threads of the first opening form threads in the first material on the head of the first fastener to secure the first fastener in place at one of a plurality of possible angles within the first opening.

Bone plate and bone plate assemblies including polyaxial fasteners

A system for fixation of bone, including a bone plate with an opening comprising threads made of a first material and a fastener with a head at least partially comprising a polymeric material that is softer than the first material. In some embodiments, when the fastener is inserted into the first opening, the threads of the first opening form threads in the polymeric material on the head of the fastener and secure the fastener in place at one of a plurality of possible angles within the first opening. The first opening additionally accepts a fastener with a substantially spherical head for compression of a fracture, or a fastener with a threaded head that engages with the threads of the threaded opening. In some embodiments the first opening includes a substantially frustoconical-shaped top portion. In other embodiments there may be a second opening that is either non-threaded or comprises a plurality of protruding fins.

Bone plates with an upper surface, a bone contacting surface, and a plurality of holes extending through the upper and bone contact surfaces for receiving bone screws are disclosed. Each hole interchangeably accepts a compression screw for compression of a fracture and a locking screw that threads into the bone plate. Provisional fixation of a bone plate to a bone may be accomplished using provisional fixation pins through the screw-receiving holes of the bone plate.
