A surgical instrument having a first assembly with a first radio-opaque portion providing a profile of a first portion of an intramedullary implant or canal in a bone, and a second assembly having a second radio-opaque portion providing a profile of a second portion of the intramedullary implant or canal. The surgical instrument may also include a third radio-opaque portion providing an alignment feature to provide a fluoroscopic planar check for the surgical instrument.

The present invention relates to an orthopaedic implant and system for fixation of bones and a method for the use of the orthopaedic implant and system. The orthopaedic system finds utility for fixation of bones such as fractures of the tibia, although it may be used in any suitable long bone.

A system includes a cartridge having an elongate body extending from a first end to a second end and having a top side and a bottom side. The cartridge defines a first hole adjacent to the first end that extends through the cartridge from the bottom side to the top side. The top side of the cartridge defines a pair of parallel slots that extend perpendicular with respect to a longitudinal axis of the cartridge. Each slot of the pair of parallel slots is equidistant from a central axis defined by the first hole.

A device for implanting an intramedullary nail includes a base member and an adjustable member coupled together and translatable relative to each other along a direction. The device includes an insertion handle configured to carry the nail and mount to the adjustable member. A drill guide is attachable to the base member and configured to carry one or more guide sleeves for alignment with locking holes of the intramedullary nail. A first reference member extends from the base or adjustable member and has a first contact portion configured to contact an exterior location of a patient's limb. A second reference member extends from the other of the base and adjustable members and has a second contact portion configured to contact another exterior location of the limb. At least one of the first and second reference members is positionally adjustable relative to the base or adjustable member from which it extends.

A guidance tool includes a body having a length extending from a first end to a second end. The body includes a shape memory section along the length of the body. The shape memory section has a curved shape.

Systems and methods are provided for processing X-ray images, wherein the methods are implemented as a software program product executable on a processing unit of the systems. Generally, an X-ray image is received by the system, the X-ray image being a projection image of a first object and a second object. The first and second objects are classified and a respective 3D model of the objects is received. At the first object, a geometrical aspect like an axis or a line is determined, and at the second object, another geometrical aspect like a point is determined. Finally, a spatial relation between the first object and the second object is determined based on a 3D model of the first object, a 3D model of the second object, and the information that the point of the second object is located on the geometrical aspect of the first object.

A surgical drill alignment guide is disclosed that can provide an accurate trajectory for placement of a bone screw along a longitudinal axis of a bone.

An implanted article physical referencing apparatus comprises a guide body, a first guide shaft and a second guide shaft. The guide body includes a plurality of guide shaft receptacles therein. A longitudinal axis of each of the guide shaft receptacles extends substantially parallel to a longitudinal reference axis of the guide body. The first and second guide shafts each have a proximate end portion and a distal end portion. The proximate end portion of the first guide shaft includes an exterior surface adapted for being engaged with a corresponding interior surface of a selected one of the guide shaft receptacles to constrain unrestricted relative movement between the first guide shaft and the guide body. The proximate end portion of the second guide shaft is attached to the guide body. A longitudinal axis of the second guide shaft extends substantially parallel to the longitudinal reference axis of the guide body.

An orthopaedic joint replacement system is shown and described. The system includes a number of prosthetic components configured to be implanted into a patient's knee. The system also includes a number of surgical instruments configured for use in preparing the bones of the patient's knee to receive the implants. A method or technique for using the surgical instruments to prepare the bones is also disclosed.

Intramedullary nails, systems, and methods. The intramedullary nail may include a generally elongate body extending from a first, distal end to a second, proximal end. The distal end may include one or more openings configured to receive one or more bone anchors that extend transversely through the distal end of the intramedullary nail, and thereby configured to secure the distal end of the nail. The proximal end may also include one or more openings configured to receive one or more bone anchors that extend transversely through the proximal end of the intramedullary nail, and thereby configured to secure the proximal end of the nail.
