Abstract: A device for securing a fractured bone together includes a main screw configured to be driven through a bone fracture, where the main screw engages a removable screw head. Another device secures a fractured bone together and includes a main screw driven through a bone fracture where the main screw includes a slot configured to engage a cross screw therethrough, where the slot includes a system that prevents lateral movement of the main screw relative to the cross screw. Yet another includes a main screw with a main portion and a movable portion, where the movable portion moves within the main portion, and where one of the main portion or movable portion includes threads configured to engage bone. And another device includes a main peg with a hook that: extends from a channel through the peg configured to engage bone.

Abstract: The device has a body with holes to accept the bone screws. The bone screws have a layer of bioresorbable material on a surface portion of the head of the screw contiguous with the shaft. Engagement between the bone screws and the body is initially through the bioresorbable material, which engagement rigidly fixes the relative angular orientation between the bone screws and the body when the device is applied to a bone. As the bioresrobable material is resorbed the angular relation between the bone screws and the body is no longer rigidly fixed, thereby effecting a transformation from rigid osteosynthesis to flexible osteosynthesis to allow micromotion between the bone fragments which promotes healing.

Abstract: A bone fixation device for treatment of a bone fracture includes a fixation screw defining a transverse opening, a fixation arm configured for inserting the fixation screw through a bone fracture, a set screw, and an aiming arm configured for inserting the set screw into the transverse opening and engagement with the fixation screw. The set screw stabilizes the fixation screw.

Abstract: A centering assembly for centering a surgical guidewire, includes a guidewire having an elongate body having a first end and a second end. The assembly further includes an expander located at the first end. The expander has a center point aligned with the elongate guidewire. An actuator is located at the second end. Actuation of the actuator moves the expander between a collapsed configuration and an expanded configuration.

Abstract: An orthopedic fixation device for treating fractures has a body with holes to accept fasteners such as bone screws and pins. Either the fasteners, or the body, or both the fasteners and the body have a layer of bioresorbable material thereon. The bioresorbable material is on the shaft or head of the fasteners and when on the body surrounding one or more holes. Engagement between the fasteners and the body is initially through the bioresorbable material, which engagement rigidly fixes the relative angular orientation between the fastener and the body when the device is applied to a bone. As the bioresrobable material is resorbed the angular relation between the fastener and the body is no longer rigidly fixed, thereby effecting a transformation from rigid osteosysthesis to flexible osteosynthesis to allow micromotion between the bone fragments which promotes healing.
