A reduction of fracture is the term used to describe a medical procedure in which broken bones are set, or reduced. Fractures of bone can result from a number of workplace injuries, including stress placed on the bone from situations such as poor ergonomics, or a sudden strike to the bone. A reduction of fracture may be either closed or open.

Devices, kits, and methods are provided for reducing a bone fracture, e.g., a vertebral compression fracture, is provided. The device comprises a plurality of resilient wires composed of a biocompatible material, such as a biocompatible polymer (e.g., polymethylmethacrylate (PMMA)). The wires can be introduced into the cavity of the bone structure to form a web-like arrangement therein. The web-like arrangement can be stabilized by applying uncured bone cement onto the arrangement to connect the wires at their contacts point. The bone cavity can then be filled with a bone growth enhancing medium.

Bone plating system
The present invention relates to a bone plating system and method for fracture fixation of bone. The bone plating system includes a bone plate, at least one locking screw, and at least one non-locking screw. The bone plate has locking holes with threads and non-locking holes. The locking screws have a shaft with a thread for engaging bone and a head with a thread configured and dimensioned to mate with the thread of the locking holes. The non-locking screws have a thread for engaging bone and a non-threaded head. Both the locking and non-locking screws remain seated in their respective holes for substantially as long as the bone plate is implanted. The non-locking screws compress the bone plate against the bone and hold fracture reduction while the locking screws are secured to the plate at a fixed angular relationship. The mixed fixation achieved by this bone plating system and method is particularly useful for treatment of per-articular fractures.

Systems and methods for reducing fractured bone using a fracture reduction cannula
InactiveUS7153306B2Relieve painRaise the possibilitySurgical furnitureSurgical needlesFracture reductionFilling materials
Systems and methods provide for the fixation of osteoporotic and non-osteoporotic long bones, especially Colles' fractures. A cannula having a circumferential opening is inserted into cancellous bone and directed such that the circumferential opening faces the fracture. The cannula is further adapted to receive an expandable structure, the expandable structure being inserted through the cannula until it is in registration with the circumferential opening. The expandable structure is expanded through the circumferential opening into cancellous bone and toward the fracture. The expansion of the expandable structure through the circumferential opening toward the fracture causes compression of cancellous bone and moves fractured cortical bone, thus creating a cavity proximal to the fracture. The cavity is then filled with a flowable bone filling material and the material allowed to harden.

Devices and methods are provided for treating a bone structure (such as, e.g., reducing a bone fracture, e.g., a vertebral compression fracture, or stabilizing adjacent bone structure, e.g., vertebrae) is provided. The device comprises rigid or semi-rigid members, each of which comprises a common base and a plurality of ribs that extent along the a longitudinal portion of the common base. The device is configured to be placed in a collapsed state by engaging the pluralities of ribs of the members in an interposed arrangement, and configured to be placed in a deployed state by disengaging the pluralities of ribs. The ribs can be any shape, e.g., flutes, that allows opposing ribs to intermesh with one another. In this manner, the device has a relatively small profile when placed in the collapsed state, so that it can be introduced through small openings within the bone structure, while preserving the shear strength of the members during deployment of the device.

Bone treatment systems and methods

A system for treating an abnormal vertebral body such as a compression fracture. In an exemplary embodiment, the system includes a biocompatible flow-through implant structure configured with a three-dimensional interior web that defines flow openings therein for cooperating with a two-part hardenable bone cement. The flow-through structure is capable of compacted and extended shapes and in one embodiment provides a gradient in flow openings for controlling flow parameters of a bone cement injected under high pressure into the interior thereof. The flow-through implant structure is configured for transducing cement injection forces into a selected direction for moving apart cortical endplates of a vertebra to reduce a fracture. In one embodiment, the flow-through implant structure is coupled to an Rf source for applying Rf energy to a two-part bone cement to accelerate curing of the cement to thereby allow on-demand alterations of cement viscosity. The Rf system allows for control of bone cement polymerization globally or regionally to prevent cement extravasion and to direct forces applied to a vertebra to reduce a fracture.

Locking compression hip screw
ActiveUS7503919B2Avoid relative motionInhibition of translationInternal osteosythesisJoint implantsRight femoral headFracture reduction
A reverse obliquity fracture of the proximal femur is poorly secured with current generation hip screws, frequently necessitating the use of intramedullary fracture fixation devices or external fixation hardware. This compression hip screw comprises a femoral head lag screw, side plate, locking plug, and compressing screw, which can be assembled in a locked mode, preventing lateral translation of the lag screw within the side plate. In the locked mode, the proximal fracture fragment(s) are prevented from displacing laterally relative to the distal fragment, as occurs commonly when such a fracture is fixed with a conventional hip screw. No change in routine fracture reduction or insertion technique is required to use this compression hip screw. Additionally, this compression hip screw can be used in a dynamic or sliding mode, if so desired, when used to fix the more common femoral neck or intertrochanteric fracture patterns.

Locking compression hip screw
ActiveUS20070270847A1Avoid relative motionInhibition of translationInternal osteosythesisJoint implantsFracture reductionIntertrochanteric fracture
A modification to the prototypical compression (dynamic or sliding) hip screw is described which expands the utility and surgical indications of this frequently used fracture fixation device to include the fracture pattern commonly referred to as a “reverse obliquity fracture” of the proximal femur. This fracture pattern is poorly secured with current generation hip screws, frequently necessitating the use of intramedulary fracture fixation devices or external fixation hardware. The described modification blocks telescopic sliding of the femoral head lag screw within the cylindrical barrel of the side plate and allows for secure locking of the lag screw within the side plate, preventing any relative motion between the screw and plate once fracture reduction has been achieved. In a locked mode, the proximal fracture fragment(s) is prevented from displacing laterally relative to the distal (diaphysial) fragment, as occurs commonly when a reverse obliquity fracture or a comminuted intertrochanteric femur fracture is fixed with a conventional hip screw. No change in routine fracture reduction or insertion technique is required to use the Locking Compression Hip Screw. Additionally, the described modification does not preclude use of the Locking Compression Hip Screw in a dynamic or sliding mode, if desired, when used to fix the more common femoral neck or intertrochanteric fracture patterns.

Bones fracture in any number of various ways and, in order to properly reduce a fracture, it may be necessary to place compression screws in any number of combinations along a bone plate to bring the various bone fragments together. A bone plate is provided with an optimal number and combination of threaded holes and non-threaded holes. In embodiments, the bone plate comprises one or more “hole pairs” in which a non-threaded hole and a threaded hole are placed adjacent to one another. The use of hole pairs enables a surgeon to place a compression screw and a locking screw in close proximity, facilitating both bone reduction and bone plate stabilization in a proximate location on the bone plate. In embodiments, the bone plate has an optimal thickness that promotes structural integrity while maximizing the number and combination of holes and reducing the profile of seated screws.
