The present disclosure relates to bone plates that are configured for use with bones having periprosthetic fractures. For example, in the event that a proximal femur is fractured in an area that is adjacent to a prosthetic component, such as a femoral stem used in a hip replacement, the periprosthetic bone plates of the present invention may be used. In one exemplary embodiment, the periprosthetic bone plates include a periprosthetic zone having a plurality of central apertures and a plurality of outer apertures that are offset from the central apertures. The periprosthetic zone may further include a plurality of indentations, each indentation extending longitudinally between adjacent outer apertures to narrow a width of the bone plate.

Periprosthetic bone plates

The present disclosure provides an orthopedic plate, in particular a plate for osteosynthesis. The plate () comprising a body (). The body () has a distal surface () adapted to be arranged facing the fractured bone and a proximal surface () adapted to be arranged facing away from the fractured bone. The surfaces () define a distal and a proximal face of the plate (), respectively. The body () further has a length measured along a longitudinal direction (), a width measured along a transverse direction (), and a thickness measured from the distal surface () to the proximal surface (). The body () comprises two longitudinal plate ends () delimiting the body () in the longitudinal direction (). The body () comprises at least one slotted longitudinal section (). The slotted section () extends over a part of the length of the body (), wherein within the slotted section () at least one slot () is arranged. The slot () extends in the transverse direction () of the body () such as to subdivide the body () in the slotted section () into at least two layers () comprising at least a distal layer () facing the fractured bone and a proximal layer () facing away from the fractured bone. The at least one slot () is arranged between the distal layer () and the proximal layer ().

Orthopedic plate

The present disclosure relates to an insert sleeve () designed for being inserted into a through hole () of an implant (), comprising a body () with a through hole () defining an axial direction () for receiving a bone anchoring element (), in particular a bone screw, said body () being made of a material having a first modulus of elasticity and including multiple recesses () arranged in circumferential direction around said through hole () of said insert sleeve () for reducing a stiffness of said insert sleeve () in a direction transverse () to said axial direction (). At least one of said recesses () is filled with a filler material () having a second modulus of elasticity different from said first modulus of elasticity.

Implantable insert sleeve

An orthopedic implant assembly is disclosed for the treatment of fracture or other trauma to a long bone. The implant assembly includes an intramedullary nail and a lag screw that extends through a transverse bore of the intramedullary nail. The intramedullary nail includes an elongated body and one or more enlarged portions positioned adjacent to the transverse bore to reinforce the intramedullary nail.

Reinforced intramedullary nail

An orthopedic nail of generally rod-like shape having a through hole extending from a first side to a second side of the orthopedic nail and being adapted to receive a screw and/or a pin, a first end of the through hole at the first side defining a rim region, wherein at least one surface notch is provided in the rim region at and restricted to an outer circumferential surface of the orthopedic nail, the surface notch being arranged transverse to a nail axis of the orthopedic nail, a width (W) of the surface notch in the direction of the nail axis being smaller than a diameter of the through hole.

Orthopedic nail and an orthopedic nail system

The present invention provides an intramedullary nail having a body with a transverse bore extending through the body and having an area of enhanced stress distribution on at least the lateral side of the transverse bore. In one exemplary embodiment, the intramedullary nail includes a cutout adjacent to the transverse bore, such as an oblique cutout, that enhances the stress distribution of the intramedullary nail in the region around the lateral opening of the transverse bore. In one exemplary embodiment, the cutout includes a ramp portion or area that defines the lateral opening of the transverse bore. In other exemplary embodiments, the cutout includes a runout or a substantially flat portion that defines the lateral opening of the transverse bore.

Intramedullary nail

A plate is provided for the treatment of bone fractures, the plate having a first surface and a second surface, the second surface being opposed to the first surface and being adapted to face a bone surface. At least one of the first and second surfaces defines at least one generally linearly shaped portion of a boundary of at least one cross section of the plate.

Plate for the treatment of bone fractures

An orthopedic screw that may be used to align and stabilize a bone fracture and a method for using the same.

Orthopedic screw

The invention relates to a bone anchoring device for the operative repair of fractures, comprising a fracture fixation plate which has at least one opening and at least one anchoring element for the fastening of the fracture fixation plate on the bone, wherein the anchoring element has a shaft and a head, and wherein at least one part of the shaft can be guided through the opening while the head can be fixed in the opening, and wherein the shaft is produced in at least two parts with a first part on which the head is arranged and with a second part provided for the anchoring in the bone, wherein the first part and the second part of the shaft are guided such that they move toward each other along an axis when the bone anchoring device is in the state of being fixed to the bone.
