    Abstract: Apparatus and methods for bone fracture repair. The apparatus may include a structural support for positioning a first bone segment relative to a second bone segment. The apparatus may include an anchoring substrate. The anchoring substrate may be configured to compress the first bone segment to the second bone segment. The anchoring substrate may transmit tension from a distal bone segment anchor in the first bone segment to a proximal bone segment anchor in the second bone segment. The apparatus may be configured to be deployed percutaneously in an inner cavity of a bone. The apparatus may be installed in an open fracture. The apparatus may be expanded, self -expanding or configured for mechanically actuation. Some embodiments of the apparatus may include a central axis member that may be used in conjunction with expansion of one or both of the structural support and the anchoring substrate to configure the apparatus.

    Abstract: Deployment systems (220) for deploying a bone fixation device are disclosed herein. One embodiment of a deployment system (220) includes a syringe-shaped body (222) configured to provide proximal traction to a bone fixation device in response to a compressive force between a finger grip (230) and a plunger (228) adapted to be engaged by the heel of a clinician's hand. The device (220) may include a collet (250) for gripping a proximal pin of a fixation device. The deployment device (220) may also include a tool (260) that includes an elongate body with a distal tip (266) adapted to rotationally engage a bone fixation device in order to axially rotate the fixation device.

    Abstract: Die Verriegelungsschraube (1) besitzt einen Schraubenkopf (2), einen Schraubenschaft (3) mit dem Durchmesser (d) und eine Zentrallinie (4), welche als Verbindungslinie der Schwerpunkte der axial aufeinanderfolgenden, orthogonalen Querschnittsflächen der Verriegelungsschraube (1) definiert ist. Sie weist ferner einen Austrittspunkt (5) am Schraubenkopf (2) und einen Austrittspunkt (6) am freien Ende des Schraubenschaftes (3) auf, wobei die Zentrallinie (4) nicht durchgehend geradlinig ist. Dank der erfindungsgemässen Verriegelungsschraube kann das Spiel zwischen der Querbohrung des Marknagels und der Verriegelungsschraube eliminiert werden.

    Abstract: A bone plating system is provided that permits maintenance of a compression force while also accommodating bony subsidence, among other features. Methods of implantation are also provided that improve alignment and placement during implantation and avoid maneuvers that weaken the vertebral bodies. A modular distraction screw is placed during the initial stages of surgery when all relevant landmarks are still intact. After completion of the surgical bone work, a proximal end of the distraction screw is detached, leaving a protruding distal segment implanted in the centerline of the vertebral bodies above and below the newly fused disc space. A bone plate is guided into proper position relative to the upper and lower vertebra by attaching the bone plate to the protruding distal segments. The distal segments of the distraction screws are tightened onto the plate and the plate is held stationary while bone screws are placed. The bone plating system is also extendable, allowing additional bone plates to be placed and coupled with existing plate components to create a multi-level plating system. Additional bone plates may be placed contemporaneously or during a subsequent surgical procedure.

    Abstract: Disclosed is a bone fracture fixation device (12), such as for reducing and compressing fractures in the proximal femur (10). The fixation device (12) includes an elongate body (28) with a helical cancellous bone anchor (34) on a distal end (32). An axially moveable proximal anchor (36) is carried by the proximal end (30) of the fixation device (12). The device (12) is rotated into position across the fracture or separation between adjacent bones and into the adjacent bone or bone fragment, and the proximal anchor (36) is distally advanced to apply secondary compression and lock the device (12) into place. The device (12) may also be used for soft tissue attachments.
