Femoral fracture fixation device with posterior support portion
Described is a femur fracture fixation device for treating a fractured, proximal end portion of a femur. The femur fracture fixation device comprises: an intramedullary nail; an extramedullary plate, including a main body portion for attachment to a lateral surface of the femur, and a posterior support portion extending from the main body portion for attachment to a posterior surface of the greater trochanter region of the femur; and a bone fastener, configured for insertion through an opening of the main body portion of the extramedullary plate, through an opening of the intramedullary nail, and into the head portion of the femur.
Lag screw systems and nail systems and methods incorporating the same
A trochanteric fracture nail system includes: a trochanteric fracture nail and a lag screw system adapted and configured for fixation medially through the trochanteric fracture nail. The trochanteric fracture nail includes: a substantially cylindrical wall defining a longitudinal bore; at least one lateral bore intersecting the longitudinal bore; and a detent on an inner surface of at least one of the at least one lateral bore. The lag screw system includes a lag screw and an interference member. The lag screw includes: an annular body defining a substantially hollow central bore; and a keel located along the annular body. The keel is adapted and configured to substantially lie within an outer profile of the annular body when in a neutral position. The interference member is adapted and configured to displace the keel radially to resist motion of the annular body by engaging with the detent of the trochanteric fracture nail.
Orthopaedic trauma devices with porous regions and therapeutic agent delivery
A device for treating orthopaedic trauma includes a device body having an exterior surface and a cannulation formed therein that extends from one longitudinal end of the device body to an opposite longitudinal end of the device body and at least one porous ingrowth material region associated with the exterior surface of the device body and fluidly coupled to the cannulation. The at least one porous ingrowth material region is configured to deliver a therapeutic agent from the cannulation to a region outside the device body.
SYSTEM AND METHOD FOR TREATING BONE FRACTURES
An intramedullary nail includes one or more nail openings extending therethrough. The intramedullary nail is implantable within a medullary canal of the bone. A bone plate is configured to engage an outer surface of the bone. The bone plate includes one or more plate openings extending therethrough. The plate openings are spaced about the bone plate such that the bone plate is positionable to axially align the plate openings with the nail openings when the intramedullary nail is implanted within the medullary canal of the bone. An aiming guide includes one or more targeting openings. The targeting openings are spaced about the aiming guide such that the aiming guide is positionable to axially align the targeting openings with the plate openings and the nail openings for extending one or more stabilizing fasteners therethrough when the intramedullary nail is implanted within the medullary canal of the bone.
Lateral cortex penetrator
A system for penetrating the lateral cortex of a long bone includes a tubular cortex penetrator having an inner surface and an outer surface, a proximal end, and a distal end comprising a beveled cutting edge configured to penetrate the lateral cortex. A guide wire is configured to pass over the tubular cortex penetrator, and a guide sleeve is configured to surround the outer surface of the tubular cortex penetrator. A hollow extraction screw with an axial bore, a proximal end, a distal end, and a threaded cutting edge is configured to pass through the axial bore of the hollow extraction screw; and the hollow extraction screw is configured to retract into a distal end of a bore through the tubular cortex penetrator.
Stereotactic Computer Assisted Surgery Method and System
A computer assisted surgical system that includes an apparatus for imaging a region of interest of a portion of an anatomy of a subject; a memory containing executable instructions; and a processor programmed using the instructions to receive two or more two-dimensional images of the region of interest taken at different angles from the apparatus and process the two or more two-dimensional images to produce three dimensional information associated with the region of interest.
ORTHOPEDIC BONE TAP AND METHODS INCORPORATING THE SAME
An orthopedic bone tap is provided, including a rod comprising a proximal end, a medial portion, and a distal end. The orthopedic bone tap also includes a plurality of cutting threads on the distal end of the rod. The orthopedic bone tap also includes an axial compression member engaged with at least one of the proximal end and the medial portion of the rod. The axial compression member is adapted and configured to exert compression that draws a bone fragment engaged with the plurality of cutting threads distally and against another bone fragment.
BONE FIXATION DEVICES, SYSTEMS, AND METHODS
A femur fixation system includes an intramedullary nail that includes a first bending stiffness and a bone plate that includes a second bending stiffness and a second torsional stiffness. In the femur fixation system either at least one of the second torsional stiffness compensates for the first torsional stiffness and the first torsional stiffness is insufficient to enable the intramedullary nail to stabilize the bone fracture independently of the bone plate or the first bending stiffness compensates for the second bending stiffness and the second bending stiffness is insufficient to enable the bone plate to stabilize the bone fracture independently of the intramedullary nail.
Femoral nail and instrumentation system
An instrumentation system (100) and an intramedullary femoral nail system (1) for antegrade or retrograde implantation with laterally inserted bone screws, the system comprising a nail stem (2) having a multi-featured proximal end (3), a distal end and a central conduit (22) configured to accommodate a fastener (4), wherein the multi-featured proximal end (3) comprises a plurality of holes (20) configured to accommodate at least two bone screws (50, 52), wherein the first bone screw (50) is at an angle that is horizontal relative to the central conduit (22) and is on a coronal plane, and the second bone screw (52) is at an angle of between 120° to 130° relative to the central conduit (22).
Hip implant device
A hip implant is provided that includes a metal acetabular cup to be inserted into an acetabulum of the pelvis, a femoral head and neck portion with a polymer femoral head molded onto a metal formal head base that is attached to a metal femoral neck rod configured to be inserted into the neck of a femur, and a metal main body shaft configured to be inserted into a femoral shaft region of the femur and secured by bone screws. The head base may have stabilizing features, such as dimples and peripheral mounds, over which the femoral head is molded. The main body shaft also has diagonal hole located at the center line of the neck of the femur to receive the femoral neck rod at an adjustable angle. The femoral head interfaces with the acetabular cup as a smooth plastic-to-metal spherical-surface joint.
