RETROGRADE FEMORAL INTRAMEDULLARY NAIL, AND RELATED SYSTEMS AND METHODS
A retrograde intramedullary nail for insertion in the medullary canal of a femur includes a body that is elongate and defines a leading end and a trailing end spaced from each other at a length sufficient to extend from an intercondylar region at least to a subtrochanteric region of the femur. The body further defines a leading portion that extends to the leading end. The leading portion defines at least one locking hole configured to receive a fixation member. The at least one locking hole defines a central hole axis that is oriented to extend through the neck and head of the femur.
Retrograde Nail with Bone Plate
A fracture fixation system includes a bone nail configured to be inserted into a canal of a bone by insertion through a distal end of the bone, such that the first end of the bone nail is configured to be seated in a proximal end portion of the bone. The fixation system further includes a bone plate defining an inner surface and an outer surface. The inner surface of the bone plate is configured to abut a lateral surface adjacent the proximal end portion of the bone. The fixation system further includes a first bone screw configured to pass through a first opening defined by the bone plate and a first opening defined by a first portion of the bone nail adjacent the first end of the bone nail to secure the bone plate and the bone nail together.
Systems and methods for intramedullary nail implantation
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. In some embodiments, the proximal opening may contain one or more relief cuts.
Arthrodesis device
The present invention relates to an improved orthopaedic device for athrodesis, in particular for the arthrodesis or fusion of a joint, for example an ankle joint, of the type comprising of a nail having head and tip ends opposed to each other; at least a first portion of the nail having an axis of symmetry; a single circular first transverse hole made in the first portion near the head of the nail and extended according to its own axis perpendicularly to the axis of symmetry; a slotted second transverse hole still made in the first portion of the nail and extended perpendicular to both the first axis of symmetry; and to the axis of the first transverse hole; and the slotted second transverse hole being made at a greater distance with respect to the head of the nail than the distance from the head of the first transverse hole.
BONE FIXATION DEVICES, SYSTEMS, AND METHODS
A combined inserter for insertion of an intramedullary nail and a bone plate together. The combined inserter includes a body that includes a longitudinal axis, a distal end, and a proximal end. The combined inserter includes an intramedullary nail coupler coupled to the body and configured to couple to an intramedullary nail; and a bone plate coupler coupled to the body and configured to couple to a bone plate.
BONE FIXATION DEVICES, SYSTEMS, AND METHODS
An intramedullary nail includes a shaft between a proximal end and a distal end. The distal end includes a first bend that extends from an anterior side of the intramedullary nail toward a posterior side and a second bend that extends from the posterior side toward the anterior side of the intramedullary nail. The two bends transfer an insertion force on a distal end of the intramedullary nail to, and along a longitudinal axis of the shaft of the intramedullary nail.
BONE FIXATION DEVICES, SYSTEMS, AND METHODS
A bone plate includes body having a bone-facing surface that faces a first side of the long bone when the bone plate is in use. The long bone includes the first side, a second side, a third side, and a fourth side. The bone plate also includes a low-profile fixation assembly that can secure one end to the long bone. The low-profile fixation assembly fixates the one end to the long bone by approaching the one end from one of the second side, the third side, and the fourth side of the long bone.
Femur fixation device
A femur fixation device includes an intramedullary nail having along its longitudinal axis a proximal portion, a distal portion and a lateral through hole extending through the proximal portion; and a hip screw capable of passing through the lateral through hole. An axis of the lateral through hole intersects the longitudinal axis at a first inclination angle. The proximal portion includes a first through hole. The first through hole is provided with a detachable positioning bracket therein. A positioning protrusion is defined at a lower end of one side of the positioning bracket. A line connecting the positioning protrusion and corresponding end points on a sidewall of the positioning bracket intersects the longitudinal axis at a second inclination angle. An outer surface of the hip screw is provided with a positioning groove. A tail nail is disposed in the first through hole.
Intramedullary nail with wire or magnet for targeting of a bone-anchor locking hole
In one embodiment, an intramedullary nail has a body that includes proximal and distal ends and an inner surface that defines at least one locking hole that extends into an outer surface of the body so as to receive a bone anchor to lock the nail in a medullary canal of a bone. The body has a first biocompatible material that defines at least a portion of the outer surface. The nail has a second material that is different from, and at least partially encapsulated in, the first material. The second material can produce at least one of an electrical current and a magnetic field, and is supported by the nail body such that a position of the at least one bone-anchor locking hole can be detected based on the at least one of the electrical current and the magnetic field.
Intramedullary rod for bone fixation
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.
