摘要:
The invention relates to an osteosynthesis implant (1) that preferably consists of a bioresorbable plastic material. The inventive implant receives the longitudinal fixation elements (10) to be anchored in the bone, especially in the form of wires, nails, pins or screws. The openings destined to receive the fixation elements (10) do not completely extend through the implant (1) like in conventional bone plates or intramedullary nails but are degenerated to indents (2) in the surface of the implant (1) so that they may serve as a guide for the fixation elements (10) to be guided through the implant (1). The inventive implant (1) allows insertion of the fixation elements (10) in the bone t diverging angles and crossing one another, so that the fixation elements (10) extending intramedullarly or in the spongiosa are primarily prevented from migrating in a proximal or distal direction.

A distal radius plate having a head with a complex palm shaped profile which flares from the sides of the plate to a leading edge that includes a central oblique linking area that helps to mark the placement of the plate relative to the radius. Further, the plate includes an oblique depression that extends from the rounded pinky side of the head and gradually morphs into the elevated styloid prominence in one diagonal direction, and rises less gradually upward into the lunate prominence on the other side of the head. A proximal plate portion mimics the spiral of the radial bone as it spirals along the longitudinal axis, and includes a tighter radial bend. The head includes holes or bores for pegs which extend into the distal portion of the radius to lock fragments into position. In the first embodiment, the angles of the pegs are fixed. In a second embodiment, one or more of the peg holes are provided with a variable axis locking mechanism assembly and the remaining holes are fixed.

A bone fixation system including a bone plate and surgical drill guide is provided. The drill guide assembly includes one or more alignment drill tubes that are remotely aligned with corresponding fastener holes in the bone plate, and a plate holder to engage a hole in the bone plate. The surgical drill guide is releasably lockable to the plate holder.

A fracture fixation plate shaping kit comprises a bone plate including a plurality of longitudinally displaced threaded holes and a plurality of removable tubular elements removably coupled in the threaded holes. A first shaping tool has a handle portion and a portion sized and shaped to engage with one of the tubular elements. A second shaping tool has a handle portion and an end portion sized and shaped to engage with another of the tubular elements. The first and second shaping tools can be engaged with the tubular elements for the manual application of force to the bone plate to bend the bone plate.

A locking plate apparatus (10) for engagement with a bone (11) is provided in accordance with the present invention. Locking plate apparatus (10) includes a plate (12) that has a body portion (20) and an internal wall (26) defining a plate hole (14) through body portion (20) and a bushing (16) with a passageway (36) therethrough. Bushing (16) is sized for polyaxial rotation within plate hole (14). Locking plate apparatus (10) also includes an attachment component (18) that has a leading portion (48) sized for extension through passageway (36) and into bone (11) and an opposite trailing portion (50). Trailing portion (50) presses bushing (16) against internal wall (26) of plate (12) to form a friction lock between bushing (16) and plate (12) in a selected polyaxial position.

A medical device (400) for handling an implant (101), the medical device (400) comprising a loading section (401) adapted to be loaded with an insert element (402) to be inserted into a hole (102) formed in an implant (101), and a guiding section (406) adapted to be guided by a pin (200) inserted into the hole (102) formed in the implant (101) for guidedly inserting the insert element (402) into the hole (102) formed in the implant (101).
摘要:
Removable drill guide tips are pre-assembled into threaded holes of a bone plate. The tips may be used with an extension to together function as a conventional drill guide. After drilling, the extension or another tool is used to remove the tips from the plate. According to another use, the tip is used as a guide for a drill bit without any additional extension and then removed with a tool.
