Abstract:
A bone fixation plate comprises a main body formed of a first material and a support member formed of a second, different material and attached to the main body. The main body defines a first set of openings and the support member defines a second set of openings aligned with the first set of openings. For each opening of the first set of openings, a main body circumferential surface is disposed adjacent and continuous with a support member circumferential surface of the second set of openings to define an opening circumferential surface that bounds an opening of the first set of openings and an opening of the second set of openings.
Abstract:
The disclosure relates to medical devices and methods of manufacturing medical devices. An intramedullary rod includes a head member, a shaft member partially disposed within a distal recess of the head member, and an outer body member disposed circumferentially around the shaft member and a portion of the head member. Medical device systems and methods of manufacturing medical devices are also described.
Abstract:
The rod coupler according to the present invention comprises two clamping jaws and locking means for locking said clamping jaws against one another. Each clamping jaw comprises an outside surface and a clamping surface, the latter providing at least a first and a second groove. Each groove runs laterally from a different part of the outside surface extending into the rod coupler, wherein longitudinal axis of the first groove and the second groove include an angle that is equal to or less than 160 degrees. Opposing grooves form an aperture. The apertures are adapted for receiving a rod if the locking means is released. Clamping jaws that are locked by the locking means clamp the rods received in said apertures.

Abstract:
A medical system includes parts used in a method for detachably establishing a spatial orientation between a body implant and an aiming device. A positioning arm being connected to the aiming device and an adaptor device being connected to or integrally formed with a bone stabilizing plate are hooked into each other. This is accomplished by means of an engaging element of the positioning arm, which engaging element is designed such that it may be coupled with an attachment element of the adaptor device. Further, there is provided a snapping mechanism which is designed to automatically engage in an interlocking element of the adaptor device, when the positioning arm, when hooked into the adaptor device, is rotated relative to the adaptor device towards a final angular position.
Abstract:
A method of connecting an intramedullary nail and a targeting and/or nailing instrument includes engaging a coupling element which has an axially parallel projection with an axially parallel recess on the hollow connection end of the nail. The engagement of the projection and recess fastens the nail under axial engagement on the connection end of the instrument in predefined rotational position on the instrument. A quick-fastener element engages in the connection end of the nail and has a first coupling element and the connection end of the nail has a second coupling element. The coupling elements are configured so that in a first rotational position relative to the axially parallel projection the instrument can be introduced into the connection end of the nail and in a second rotational position the coupling elements cooperate so that the nail is held axially fixedly on the instrument.

Abstract:
An osteosynthetic aid for tubular bones includes a locking nail which has a shank and, at the two ends of said shank, has at least one cross-bore for a headed locking screw. A biasing sleeve is resiliently deformable in an axial direction and is disposed between the head of the locking screw and the shank of the locking nail. The sleeve maintains the cross-locking screw under tension to keep the shank of the nail from shifting during use.

Abstract:
A locking nail for treating fractures of tubular bones has at least one cross-bore is provided at one end for the reception of a bone screw. The nail has a female thread at the end with the cross-bore for connection to a nail retention screw. The nail has an anti-rotation feature to anti-rotationally secure the rotational position of a joining sleeve which joins a targeting apparatus relative to the locking nail.
