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: The present application provides a new and innovative device for aiding in screw installation through a distal end of a nail installed in a patient's bone (e.g., humerus). The nail's distal end is disposed away from an insertion point of the nail into the bone. The targeting device includes a targeting body having an outer frame, a flexible member connected to the outer frame, a targeting block having multiple holes and connected to the flexible member such that the flexibility of the flexible member enables the targeting block to translate towards sides of the outer frame, and an adjustment assembly that adjusts and maintains the targeting block's position relative to the sides of the outer frame. The targeting device further includes a base plate removably coupled to the targeting body. The targeting device may be coupled to the nail at the base plate.

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: An implant system for use in orthopaedic surgery for fixation of bone includes an intramedullary nail and a coupling member. The intramedullary nail includes a proximal portion defining a longitudinal axis. The proximal portion includes an axial bore defining an axis substantially parallel to the longitudinal axis of the proximal portion and a transverse bore configured to receive a bone fastener. The coupling member includes a through hole and is movably arranged within the axial bore of the proximal portion. Further, the coupling member includes a drive portion and a bone fastener engagement portion. The drive portion is in one variant non-rotatably coupled to the bone fastener engagement portion. The bone fastener engagement portion is configured to engage the bone fastener penetrating the transverse bore. In one variant the engagement is realized via an extended contact region.

Abstract: A targeting system for aligning an axis of a targeting sleeve and a bore in a distal end portion of an intramedullary nail is proposed, the targeting device comprising a distal targeting arm with a first end being configured to be coupled to a trailing end of an intramedullary nail, an adjusting device, the adjusting device being configured to be coupled to the distal targeting arm. The adjusting device may comprise an adjusting element and a nail follower including two targeting holes each being configured to receive a sleeve assembly. The adjusting element may cooperate with the nail follower such that the positions of the two targeting holes are adjustable so as to correspond to respective locking holes at a leading end of the intramedullary nail, even when the nail is bent.

Abstract: A sleeve clamp has a body with a through bore for receiving a sleeve, and a clamping element. The clamping element includes a clamping edge and may be arranged at the body so as to be movable between two positions, i.e. a neutral position and a deflected position. In the neural position, the clamping edge protrudes laterally into a lumen which is occupied by the sleeve when the sleeve is received in the through bore. In the deflected position, the clamping element may be elastically deformed and the clamping edge does not protrude into the lumen which is occupied by the sleeve when the sleeve is received in the through bore.
