A tether for an implantable bone device, the tether including a retention portion for holding the implantable bone device in place, wherein the retention portion comprises a recess configured to receive a protruding proximate end of the device when the device is positioned inside a bone, wherein the recess is open at a first end and closed at a second end; and a fastening portion for affixing the tether to the bone, wherein the fastening portion comprises one or more through fastener openings, wherein each through fastener opening is configured to receive a bone fastener, wherein the fastening portion is adjustable, and wherein the fastening portion is shaped to be less thick that a height of the retention portion.

A cerclage system used to affix a bone includes a tension plate, a cable lock, and a cerclage cable configured to encircle the bone. The tension plate, which is engageable with the cerclage cable, is moveable between a natural shape and an insertion shape where the tension plate stores energy. The cable lock locks the cerclage cable about the bone in engagement with the tension plate. The tension plate is configured for positioning atop the bone while residing in the insertion shape. The tension plate, through an engagement thereof with the cerclage cable and upon attempted movement thereof from the insertion shape toward the natural shape, delivers the energy stored therein to the cerclage cable thereby tensioning the cerclage cable such that the cerclage system continuously compresses the bone.

Provided are a locking steel plate and a locking steel plate assembly with the locking steel plate. Herein, the locking steel plate may include a steel plate body, an elastic block hook and a limit groove. The steel plate body is provided with a mounting hole, and the mounting hole may include a first hole section and a second hole section having a cross section area less than that of the first hole section. The elastic block hook is provided inside the first hole section, a first end of the elastic block hook is connected with the steel plate body, and a second end of the elastic block hook bends toward the second hole section. The limiting groove is provided on an inner wall of the second end of the elastic block hook.

Disclosed is a surgical instrument for tightening a bone fixation member around bone. The instrument comprises a body with a gripping portion extending from the body and configured to be grasped by a hand, a clamp for clamping a bone fixation member and a clamp carrier connected to and movably guided relative to the body. The clamp is connected to and movably guided relative to the clamp carrier. The instrument further comprises an actuator connected to and movably guided relative to the body, and configured to be operated by a hand, wherein the actuator is configured to move the clamp carrier via the clamp.

An implant for bone fixation is presented. The implant comprises an elongated member configured to be wound around bone parts that are to be fixed. Further, an engagement feature is provided that is coupled to the elongated member and configured to engage a portion of the elongated member so as to secure the implant in a loop around the bone parts. A fastening member is arranged between and coupled to the elongated member and the engagement member. The fastening member comprises at least one opening for receiving a bone fastener. In one variant, at least one visual indicator indicating a region of the fastening member to be severed in order to detach the implant is provided. In another variant, at least one of the engagement member and the elongated member are coupled to the fastening member by injection molding.

The invention primarily relates to fastening and stabilizing tissues, implants, and/or bondable materials, such as the fastening of a tissue and/or implant to a bondable material, the fastening of an implant to tissue, and/or the fastening of an implant to another implant. This may involve using an energy source to bond and/or mechanically to stabilize a tissue, an implant, a bondable material, and/or other biocompatible material. The invention may also relate to the use of an energy source to remove and/or install an implant and/or bondable material or to facilitate solidification and/or polymerization of bondable material.

A device for the cerclage of fractured bone as well as to a cerclage system using such device are provided. The cerclage device comprises a cerclage wire or thread and at least one spacer arranged on the cerclage wire or thread. The at least one spacer is made as a band having a substantially rectangular plan and a concave profile. Owing to the concave profile, the band can adapt to the surface of the fractured bone; in addition, the force exerted on the bone by the cerclage wire is advantageously distributed over the entire surface of the band. The cerclage device further comprises at least one safety thread which allows preventing the spacer from becoming lost in the patient's body in case the cerclage wire or thread tears off.
