Abstract: An orthopedic joint hinge assembly includes a first elongated member, a first coupler attached to the first elongated member and including a first interface surface, a second elongated member, and a second coupler attached to the second elongated member and including a second interface surface. Each of the first and second couplers is constrained to rotate about an axis of rotation. The first and second interface surfaces are offset from the axis of rotation and engage each other to block a relative rotation between the first and second members in a first direction and separate from each other to permit a relative rotation in an opposite direction.

Abstract: Collapsible orthopedic fixation assemblies and related methods are disclosed. A collapsible fixation assembly includes end frames that are coupled with one or more cross beams. The fixation assembly is reconfigurable between a collapsed configuration in which the end frames are substantially aligned with the one or more cross beams and a deployed configuration in which the end frames are oriented transverse to the one or more cross beams and in which relative movement between the end frames and the one or more cross beams can be inhibited. The fixation assembly is configured to support at least one bone-interface component, which is configured to constrain a bone of a patient. In the collapsed configuration, the fixation assemblies is more compact than in the deployed configuration, thereby making it more easy to store and transport as compared to a comparable non-collapsible fixation assembly.

Abstract: The invention provides an orthopedic external fixation system for treatment of lower and upper extremities fractures. The system comprises an elongate base rail supported by a stand structure and a plurality of open rings slidably and removably coupled to the base rail along the base rail length. The ring members are connected to struts that support flag members, which support wires and pins that interact with the fractured bones for fixation of their positions relative to the rings during treatment. The system has means for combining the rings into separate modules that can be moved relative to each other. Through the use of the struts the rings can be bound into an integral system that can be disconnected from the base and the stand structure, while remains in a working position on the injured limb of the patient.

Abstract: Bulk solidifying amorphous alloys (BMGs) having improved corrosion resistance properties; and more particularly a sub-set of Zr—Ti-based BMGs having improved corrosion resistance properties are provided. The BMG compositions are formed by carefully controlling the concentration of, or removing altogether, highly electronegative elements, such as Ni and Cu from Zr—Ti-based bulk solidifying amorphous alloys thereby producing BMG materials with corrosion resistance properties that far exceed those of current commercially available BMGs and most conventional alloys. The elimination of these electronegative materials also opens the possibility of new uses for BMGs, including in biological applications.

Abstract: Methods and structures for removing a bone fragment from a body of a patent. A method can include advancing a distal portion of an orthopedic extraction device into a bone fragment disposed in a bone mass in the body of the patient, and actuating one or more deployable members of the distal portion of the device positioned in the bone fragment so as to engage the bone fragment with the device. With engagement between the device and bone fragment, a force or torque to the device so as to remove the bone fragment from the bone mass of the patient.
