A plate for attaching to an anatomic structure with fasteners. A body defines openings for receiving the fasteners, and includes a bottom surface that is concave. The plate includes bone pad surface, and a spike extends away from the bone pad surface. The bone pad surface is oriented at an angle relative to the bottom surface to prevent further penetration of the spike into the anatomic structure beyond a predetermined depth. The bone pad surface may be oriented at an obtuse angle relative to the bottom surface. The bone pad surfaces may be planar or concave, or contoured to a corresponding profile of the anatomic structure. The spikes may be pyramidal or conical. At least one side of the spike may be integral and continuous with the bottom surface. The side may have a radius of curvature equal to that of the bottom surface.

Provided is a locking plate system for treatment of a distal radius fracture including a locking plate (4) that is a flat laminate of intermediate molding materials that includes carbon fibers as a reinforcing material and thermoplastic resin as a matrix; a screw anchor (5) having a shaft portion (10) which has a principal thread (13) achieving a self-tapping action formed thereon and an outer circumference of a head portion of the screw anchor (5) which has an auxiliary thread (13) achieving a self-tapping action tapped thereon; and a through-hole (6) in the radius locking plate (4), which allows the radius main body (3) and the fractured bone piece (2) to be threadably fixed to the radius locking plate (4) and having a diameter that is oversized relative to the principal thread (11), and that is undersized relative to the auxiliary thread (13).

A tracking device for a surgical navigational system. A tracking head includes tracking elements configured to communicate tracking information to the surgical navigation system. An extension arm is configured to be coupled to the tracking head, and a bone plate is configured to be coupled to the extension arm. The bone plate is further configured to be coupled to anatomic structure and includes openings each configured to receive a fastener. A central opening may be provided to receive an additional fastener for coupling the extension arm to the bone plate. A recess within the top surface may receive the base plate of the extension arm. Spikes of the bone plate are configured to penetrate the anatomic structure and, in conjunction with the fasteners, prevent movement of the tracking device. The bottom surface is concave between the spikes to define a space configured to accommodate portions of the anatomic structure.

A drug-impregnated sleeve for encasing a medical implant is provided. In one embodiment, the sleeve may include a body made of a biologically-compatible material that defines an internal cavity configured to receive the medical implant. In one embodiment, the biologically-compatible material is bioresorbable. The body may include a plurality of apertures, such as perforations or holes, extending from the cavity through the body. The sleeve may further include a first end, a second end, and a drug impregnated into the resorbable sheet. In one possible embodiment, the first end of the sleeve may be open for receiving the medical implant therethrough and the second end may be closed. The implant may be encased in the sleeve and implanted into a patient from which the drug is dispensed in vivo over time to tissue surrounding the implantation site. In one embodiment, the body is made from at least one sheet of a biologically-compatible material.

Surgical plating systems, devices, and related methods for stabilizing and immobilizing portions of a body for surgical procedures, e.g., spinal surgery, are disclosed herein. The plating systems can have narrow profiles that minimize trauma to the patient. An exemplary bone plating system can include a bone plate having one or more holes for receiving attachment members to couple the bone plate to a bony structure. The plating system can provide multipoint fixation to anatomical structures of the patient to prevent unwanted migration of the bone plate and/or unintentional back-out of the attachment members. In some embodiments, the attachment members can be disposed at various trajectories and angles relative to plating structures and can include a mesh construct and/or additional locking features. In some embodiments, the plating system can be introduced into the patient via an access tube to further limit the invasiveness of the procedure.

A device for coaptation of bone parts or bone fragments, comprising an integral plate obtained by moulding whereof one portion (1) is made from a first biocompatible polymer comprising at least one or, preferably, a plurality of areas or inserts (2) provided with a through hole (3), said areas or inserts being made from a second biocompatible polymer which is more malleable than the first polymer, said areas or inserts having mechanical properties allowing a self-tapping of the inner surface of the holes, by means of screws that can be used for securing said plate to bone tissue, said support portion and said areas or inserts having a partial molecular bond between them.

A compression plate for use with treating a fracture on a bone includes a main body portion comprising a pair of opposing ends and a pair of arms. Each arm of the pair of arms extending from a respective end of the pair of opposing ends. The compression plate also includes a bending feature defined in at least one of the main body portion and the arms. The bending feature is configured to enable deflection of at least one of the main body portion and the arms such that the bending feature applies a compression force on the bone.

A device for coaptation of bone parts or bone fragments, comprising an integral plate obtained by moulding whereof one portion (1) is made from a first biocompatible polymer comprising at least one or, preferably, a plurality of areas or inserts (2) provided with a through hole (3), said areas or inserts being made from a second biocompatible polymer which is more malleable than the first polymer, said areas or inserts having mechanical properties allowing a self-tapping of the inner surface of the holes, by means of screws that can be used for securing said plate to bone tissue, said support portion and said areas or inserts having a partial molecular bond between them.

A bone fixation plate comprises a main body formed of a first material and a support member formed of a second, different material and attached to the main body. The main body defines a first set of openings and the support member defines a second set of openings aligned with the first set of openings. For each opening of the first set of openings, a main body circumferential surface is disposed adjacent and continuous with a support member circumferential surface of the second set of openings to define an opening circumferential surface that bounds an opening of the first set of openings and an opening of the second set of openings.
