An orthopaedic fixation assembly for prosthetic biologic attachment. The orthopaedic fixation assembly may include a main body with a longitudinally-extending stem having a proximal end, a distal end, and a cavity body. An anchor plug may be configured to be received within the stem cavity, and securable thereto via complementary mating surfaces. A spindle structure may be fixedly attached to the proximal end of the longitudinally-extending stem and protrude outwardly therefrom such that a portion of the structure extends externally beyond the resected cavity of the bone that may prevent rotational motion of the spindle. The spindle structure may have at least one compliant biasing member configured to apply a compressive force to the surrounding bone. A porous coating may be at the juncture between stem and spindle structure, on the spindle, and the splines and anti-rotation chocks, improving the initial stability of the implant and facilitating long-term bone ingrowth.

Intramedullary nails, aiming guide assemblies, and methods. The aiming guide assembly can include an aiming guide having an elongate proximal handle portion. A generally arcuate distal implant alignment tip connector portion is connected to the proximal handle portion and has a distal implant alignment tip extending along a tip axis parallel to a longitudinal axis of the proximal handle portion. A recon module may be releasably attached to a proximal end of the proximal handle portion. An oblique module may be releasably attached to the distal implant alignment tip portion.

The invention concerns a distal radius fracture fixation device for securing at least two fractured bone segments together. The device comprises: a body portion comprising at least two insertion channels each extending through the body portion and each being configured for receiving a bone fixation element therethrough; and an insertion device connection portion connected to the body portion, and for coupling a separate insertion device to the fracture fixation device. The insertion device connection portion is arranged to be decoupled from the body portion.

The invention is directed to a surgical device which is externally used as aiming device that permits accurate placement of surgical wire to mend a supracondylar fracture. The device of the invention decreases operative time, risks of the re-dislocation through continuous manipulation, radiology exposure for both the patient and operation room staff, and to decreases anesthesia duration. It is also directed to surgical use of the device for repair of a supracondylar fracture and to methods for making it.

An intramedullary nail implant for positioning in a bone having a head and a shaft defining an intramedullary canal. The implant includes a distal portion having a shaft extending along a central axis and configured for positioning within the intramedullary canal. A proximal portion extends proximally from the distal portion. The proximal portion defines a contact surface which extends at least in part medially of the central axis such that it is configured to extend within a medial portion of the bone head. A method of implanting the nail is also provided.

A method of treating a bone fracture includes taking a first 2D image of an implant and a reference body with an imaging device; creating a 3D orientation of the reference body and the implant based on the 2D image; determining an actual axis of delivery of a bone screw through an opening extending through the implant; determining an optimal axis of delivery of the bone screw through the opening such that the optimal axis of delivery guides the bone screw toward a medically optimal location; and moving the implant such that the optimal axis of delivery and the actual axis of delivery coincide.

A system includes a bone anchor including a shank having a first end, a second end, a channel extending through the shank with a channel axis, and an internal advancement structure having at least a portion being closer axially to the second end than to the first end, and an elongate instrument configured to extend through the channel, with a tip portion and an external advancement structure configured to cooperate with the internal advancement structure. Engagement between the advancement structures facilitates holding of the tip portion at a first axial position relative to the bone anchor and movement of the tip portion from the first axial position towards both the first and second ends of the shank. The tip portion and the external advancement structure of the elongate instrument are insertable into and removable from the channel via the first end of the shank.

An apparatus including a sterilizable tray having a base and at least one fixture connected to the tray adapted for removably securing an implant insertion device to the tray. The tray can be free of a first wall portion for permitting the proximal end of an implantable device to axially align with the end of the implant insertion device for coupling to the implant insertion device and can be free of a second wall portion for permitting a tool to axially align with the end of the implant insertion device so as to threadedly couple the implant insertion device to the implantable device. Related methods and apparatus are provided.

A periprosthetic fracture repair solution that provides a variety of fracture fixation options should a fracture occur after total hip, knee, or especially a total shoulder arthroplasty, and provides associated methods and apparatus for application of provided fixation. The ability to pre-engineer fracture fixation contingent solutions into humeral components provides for a distinct clinical advantage in the planning and execution for periprosthetic fracture fixation. Said methods and apparatus include targeting devices which allow for intimate association of fixed angle locking screws in pre-drilled holes in an existing prosthetic or other components including additional fixation components. Such apparatus and methods further include the use of alignment devices and other components to allow for ease of repair of periprosthetic fractures utilizing the pre-engineered solutions. Such targeting devices are required in specific circumstances as the prosthetics may prevent x-ray imaging and consequently free hand alignment.

Systems and methods for fixing bone using an intramedullary nail locked to an encircling anchor including a bushing and a locking member. An exemplary system may include any combination of the nail, one or more bushings, one or more locking members, an instrument to guide installation of the bushing, at least one drill, and a driver that attaches to the bushing. The instrument may define a guide axis and be configured to be coupled to a bone such that the guide axis extends across the bone. The instrument may be used to guide a drill, the bushing, and/or the locking member along the guide axis into the bone. The nail may be configured to be placed along the medullary canal of the bone such that the nail extends through the bushing, and the locking member may be configured to lock the nail to the bushing.
