A fixation device for treating an epiphyseal fracture, comprises a shaft extending longitudinally along a central axis from a first end to a second end configured to slidably engage a bone implant opening and a having a maximum radius r and a spherical head element attached to the first end of the shaft and having a radius R>r, the spherical head element configured to be inserted into a fragmented portion of bone such that the fragmented portion rotates about the spherical head element relative to the central axis of the shaft.

A system includes an implant and a packaging device assembled with the implant to hold an outer sleeve and a head element of the implant in a desired position relative to one another. The packaging device includes clip arms sized and shaped so that, when the arms are held toward a closed configuration, the implant is housed therebetween in the desired position and proximal ends of the arms form a space via which an insertion device is insertable to be coupled to the implant, and a housing defining a space within which the clip is housed. The housing includes a retaining feature for retaining the clip therein and a camming element which, when a proximal force is exerted on the implant via the insertion device coupled thereto, causes the arms to move away from one toward an open configuration to release the implant therefrom.

The present invention is directed to a bone plate and its method of use for reducing a bone fracture, the bone plate having a longitudinal axis, the bone plate comprising an upper surface, a lower surface, a first hole for engaging a head of a first bone anchor. The first hole is configured and adapted to fix a shaft of the first bone anchor along a first axis. A second hole is spaced apart from the first hole along the longitudinal axis. The second hole is for engaging a head of a second bone anchor, and is configured and adapted to fix a shaft of the second bone anchor along a second axis. The first hole and the second hole are configured such that the first axis and the second axis define a single plane and intersect at a point below the lower surface. The shafts of the first and second bone anchors may touch or nearly touch at the point of intersection, such that the first and second bone anchors form a truss.

Provided is an intramedullary (IM) rod for bone fixation. The IM rod is configured to be placed in an intramedullary cavity of a center portion of a part of a fractured bone which is required to be fixed to another part of the fractured bone, and lengthily extends in a direction of the part of the fractured bone, wherein the IM rod includes a plurality of guide holes configured to guide fasteners which are inserted through the part of the fractured bone and fastened to the other part of the fractured bone, and the plurality of guide holes include a main hole and a pair of sub-holes provided at positions forming vertices of a triangle together with the main hole.

A bone plate comprises a body including an elongated opening extending therethrough, the opening being open at a distal end of the body and including a distal portion and a proximal portion, the distal portion having a width smaller than a width of the proximal portion, the width being a dimension between two longitudinal sides of the opening extending parallel to a longitudinal axis of the body, the body further including an insert including a head portion and a base portion, the base portion being shaped to be slidably mounted within the proximal portion of the opening, a diameter of the base portion being larger than a width of the distal portion of the opening such that the base portion is prevented from exiting the opening through the distal portion thereof, the insert further including a central fixation element receiving hole configured to receive a bone fixation element therethrough.

Orthopedic surgical implants include an implant plate. The implant plate may include a proximal plate segment having a generally concave proximal bone engaging portion. A middle plate segment may extend from the proximal plate segment. The middle plate segment may have a generally convex middle bone engaging portion. A distal plate segment may extend from the middle plate segment. The distal plate segment may have a distal bone engaging portion. At least one proximal fastener opening may be provided in the proximal plate segment of the implant plate. At least one distal fastener opening may be provided in the distal plate segment of the implant plate. At least one proximal compression fastener may extend through the at least one proximal fastener opening. At least one distal tension fastener may extend through the at least one distal fastener opening. The orthopedic surgical implants may be suitable for repair of a fractured femoral neck and pertrochanteric fractures.

An assembly and method are disclosed. The assembly includes an orthopaedic implant and an active compression member. The implant has a compression screw hole with a step and the active compression member includes an outer tube and an inner slide. The tube and slide allow the proximal end portion and the distal end portion to move relative to one another. The method includes inserting a guide wire, placing a drill over the guide wire and drilling into a femur, tapping the drilled hole, using a compression device to reduce the fracture using the orthopaedic implant step, and inserting one or more active compression members into the tapped hole.

Fracture fixation devices and methods achieve stabilization of a bone fragment. A nail section of the device is dimensioned to be positioned within an intramedullary canal of a bone such that the nail section spans a fracture site in the bone. The nail section bends into a post-insertion configuration different from a pre-insertion configuration when inserted into the intramedullary canal. The nail fastening section is connected to the nail section by a connecting element on a first side of the fracture site. At least a portion of the nail fastening section is positioned outside the bone. A first end of the nail section and a second end of the nail fastening section are positioned on an opposite second side of the fracture site when the fracture fixation device is implanted in the bone.

A bone plate for implanting in a femur bone having a prosthesis implanted therein includes a shaft portion defining a plurality of holes and a trochanteric portion proximal to the shaft portion having two arms forming a concave shape and defining a plurality of first holes for receiving screws such that when implanted, the two arms at least partially wrap around and attach to the femur bone. The bone plate may include at least one bendable extension positioned between both of the arms. Each of the extensions may define at least one second hole.

The cephalomedullary nailing system of this invention contributes to solving three main problems: reduce fractures, improve assembly biomechanics to ensure the load axis is favorable as possible for bony fragments and prevent femoral neck collapse as well as offset and limb length loss, hence avoiding the possibility of reduced abductor power. The system is based on specific screw channel geometry and the placement of an additional locking screw, allowing the nail to turn 360 and facilitating nail insertion through the screw.
