Abstract: A universal clamp apparatus for orthopedic exterior fixators is disclosed. Preferably, the universal clamp apparatus has two pin/rod clamps, each having seating grooves for attaching to a frame rod associated with a frame of the fixator and/or a bone pin for implantation in a bone fragment. A clamp screw extends through and connects the first and second pin/rod clamps. An ergonomically designed knob having at least one collapsible or non-collapsible turn lever acts as a torque amplifier when rotated by hand without tools to tighten and untighten the pin/rod clamps to the frame rod and/or bone pin by movement along the clamp screw. The pin/rod clamps have planar sides that are contiguous and have radial ratchet grooves that are in mating engagement and provide a ratcheting mechanism so that the rotation of the pin/rod clamps relative to each other occurs in incremental rotational steps.

Abstract: A bone plate for treating periprosthetic fractures includes a head portion sized and shaped so that, in an operative position, a proximal end thereof aligns with a vastus ridge of a greater trochanter of a femur. The plate also includes a shaft portion extending distally from the head portion. The shaft portion includes offset holes to receive bone fixation elements therethrough. Each of the offset holes includes a first hole positioned on a first side of a longitudinal axis of the plate and a second hole positioned on a second side of the longitudinal axis opposite the first side so that bone fixation elements inserted therethrough extend anterior and posterior of a prosthetic received within the femur. The first and second holes are staggered relative to one another along a length of the shaft portion and extending beyond longitudinal edges of the shaft portion.

Abstract: Embodiments of a universal clamp apparatus for an orthopedic exterior fixator are disclosed. The universal clamp apparatus can be operated without the need for tools, with extraordinary tightening precision, and with low risk of losing stability. The universal clamp apparatus has at least one pin/rod clamp, but preferably two pin/rod clamps. Each clamp has seating grooves for snapping in and attaching to at least one of the following: a frame rod associated with a frame of the fixator and/or a bone pin for implantation in a bone fragment. A screw mechanism, such as a clamp screw, extends through and connects the first and second pin/rod clamps. An ergonomically designed knob having at least one collapsible or non-collapsible turn lever acts as a torque amplifier when rotated to tighten and untighten the pin/rod clamps to the frame rod and/or bone pin by movement along the clamp screw.

Abstract: A bone plate for treating periprosthetic fractures includes a head portion to be positioned along a greater trochanter of a bone. The head portion includes pairs of bone fixation element receiving openings extending therethrough from a first surface of the plate which, when the plate is in an operative position, faces away from the bone, and a second surface which, when the plate is in the operative position, faces toward the bone. A pair of cable holes extend through the head portion from a first longitudinal side connecting the first and second surfaces to a second longitudinal side connecting the first and second surfaces. The head portion includes a pair of hooks for engaging a superior ridge of the greater trochanter. The plate also includes a shaft portion extending distally from the head portion to extend along a portion of the bone distal of the greater trochanter.

Abstract: A plate for treating a bone includes a plate body extending along a longitudinal axis from a first end to a second end and being sized, shaped and contoured to be positioned along a desired surface of a bone. The plate also includes a slotted opening extending through the plate body and defined by a first portion sized and shaped to permit a head portion of a bone fixation element fixed to the bone to be passed therethrough and a second elongated portion extending along the longitudinal axis from the first portion in communication with the first portion, the second portion sized to prevent the head portion of the bone fixation element from being passed therethrough so that, when the head portion of the bone fixation element is received through the first portion, the plate is slidable relative thereto such that the second portion engages the head portion of the bone fixation element.

Abstract: A device for electromechanically and/or electro-pneumatically positioning a fractured bone having a first clamping unit adapted for attachment to the bone by at least one first bone fastener, a second clamping unit adapted for attachment to the bone by at least one second bone fastener, and at least one of: (i) a translation component operatively driven by a translational driver for relative translational movement of one clamping unit with respect to the other along a translational axis; (ii) an angulation component operatively driven by an angulational driver for relative angulational movement of one clamping unit with respect to the other along an articulation axis; and (iii) a rotational component operatively driven by a rotational driver for relative rotational movement of one clamping unit with respect to the other along a rotational axis.

Abstract: A mold assembly and method of forming a surgical implant from bone cement. The method has the steps of connecting a plurality of mold segments to approximate the size of a patient implant. Each mold segment has an open channel. The method may further include aligning the channels of connected mold segments, positioning a centralizing holder on a reinforcement member, mixing bone cement, pouring at least some bone cement through the channels and into connected mold segments, fitting the reinforcement member into the mold segments, curing the bone cement; and removing the cured surgical implant.
