Devices, methods and systems for remedying or preventing fractures of the bone are disclosed. The devices, and corresponding methods and systems, may include first and second members each having a proximal end, a distal end and a middle portion and an outer surface. The first member may be configured to be positioned at least partially within the femoral neck of the femur. The second member may be configured to be oriented at an oblique angle relative to the first member and mechanically engaged with the first member through an interlocking connection between the distal end of the second member and the middle portion or the distal end of the first member.

A device for correcting a placement of a guide wire in a bone includes a body extending from a proximal end to a distal end; a central channel extending through the body from the proximal end to the distal end along a central axis, the central channel sized and shaped to receive a guide wire slidably therein; and a first correction channel extending through the body from the proximal end to the distal end. The first correction channel is sized and shaped to receive a guide wire therein at an angle relative to the central axis of the central axis of the central channel.

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 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.

A patient-specific arthroplasty system comprising a database comprising preoperative data, ligament balancing tool data, and postoperative data associated with a plurality of patients, a preoperative evaluation module that receives preoperative data for a given patient, an analysis engine that analyzes the database, receives the preoperative data, and generates a surgical recommendation based on the preoperative data of the given patient and the analysis of the database, and a pin positioning block module that receives the surgical recommendation and determines a pin positioning block based on the surgical recommendation.

A bone nail for stabilizing a fracture. The bone nail having a head portion and a stem portion. The stem portion offset from the longitudinal axis of the head portion. The nail including a continuous passageway extending from a rear edge of the nail to a front edge of the nail. The continuous passageway including a bore extending longitudinally through the head portion and both a groove and a bore in the stem portion.

A method and device for attaching a bone plate to a bone includes the steps of placing a first surface of a wire insertion device against the bone, inserting a reference wire through an opening of the wire insertion device extending therethrough from the first surface of the wire insertion device to a second surface of the wire insertion device, removing the wire insertion device from the reference wire and positioning a bone plate on the bone by moving the bone plate in a transverse direction relative to a longitudinal axis of the reference wire so that the reference wire is received within a slot of the bone plate, the bone plate including a first surface facing toward the bone and a second surface opposing the first surface, the slot open to a lateral side surface connecting edges of the first and second surfaces.

The invention relates to a method for visually assisting the alignment of a medical instrument, wherein the instrument is visually displayed on an image output in a positional relationship to a part of a patient's body by means of a medical navigation system, wherein an orientation aid is displayed as a virtual model shape at the instrument or in a particular positioning with respect to a characteristic part of the instrument. It also relates to a planning method for optimized instrument alignment with the aid of such an image assisting method.

Methods for preparing a bone in surgery using an imaging system, a navigation system having a locating device, and a robotic system having a cutting tool. A cannula is guided into an incision to expand the incision and provide access to the bone so that the cutting tool is insertable through the cannula to remove material from the bone. An implant is insertable through the cannula to be placed in the bone.

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 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.

Surgical Guide for Positioning a Resurfacing Head Implant The present invention relates to a guide for positioning a resurfacing head implant into the appropriate position and angles on the femur bone. The present invention therefore provides a guide system for an implantable device (e.g. a resurfacing head implant), said guide system comprising a first component arranged to act as a clamp and a second component arranged to interact with the first component to prevent movement of said first component when clamped.
