Disclosed is a combined intramedullary and extramedullary bone stabilization and alignment system, which includes both methods and apparatuses for the alignment and stabilization of a first bone or piece of bone to a second bone or piece of bone. Embodiments of the system may include an implant device which has an elongated framework within the intramedullary portion and an extramedullary portion which are cannulated. The cannulated aspect of the framework includes a wire aperture through both the intramedullary portion and the extramedullary portion.

20190365435 · 2019-12-05 ·

Embodiments described herein provide an implant for rigid intramedullary fixation of the hindfoot complex with the midfoot and/or forefoot and methods of implanting the same. Embodiments described herein can allow for the implant to be adapted to the patient based upon the extent of bone loss and instability. Embodiments herein also provide a jig system to facilitate the shaping of the foot and/or the implantation of the described internal fixation systems.

INTERNAL FIXATOR FOR BONE FRACTURE
20190336186 · 2019-11-07 ·

A bone fracture internal fixator for repairing a bone fracture of a femoral neck that allows load to be applied to the associated bone parts evenly, and increases the connecting strength between the femoral head and femoral shaft while minimizing the risk of the femoral head being torn apart by the inner connecting member by increasing the diameter of the inner fixing member. The central axial line of the femoral head is offset from the central axial line of the intramedullary nail placed in the medullary cavity of the femoral shaft. In order to bring the inner fixing member such as a lag screw configured to be inserted through the femoral neck close to the central axial line of the femoral neck, the central axial line of the through hole for receiving the inner fixing member is offset from the central axial line of the intramedullary nail.

INTRAMEDULLARY FIXATION DEVICES

An internal intramedullary fixation device for the stabilization of bone in arthrodesis and fractures of the foot and hand is disclosed. During implantation in medullary canals of bones, the device grasps the edges of the canals, stabilizing the bones, internally, during a healing process. The intramedullary fixation device comprises arrow-shaped proximal and distal heads comprising tips and a pairs of wings, the heads being sized to fit within an intramedullary canal of a bone. The intramedullary fixation device also comprises a rigid body defining a longitudinal axis connecting the proximal and distal heads. The rigid body comprises an intermediate portion, a distal neck portion connecting the rigid body to the distal head, and a proximal neck portion connecting the rigid body to the proximal head, the neck portions having a cross-sectional area smaller than a cross-section area of the intermediate portion.

Fusion implant

An implant that facilitates the fusion of a first bone part with a second bone part includes an implant body that extends between the first bone part and the second bone part. The implant body includes a first portion that fits within a first receiving aperture in the first bone part, and the implant body includes a second portion that fits within a second receiving aperture in the second bone part. At least one of the first portion and the second portion can be made of bone. Additionally, at least the second portion is formed to have a non-circular cross-sectional shape to inhibit relative motion between the bone parts and the implant body.

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 end may further include a cross-locking feature, which includes a second bone anchor that interlocks with a first bone anchor, for example, for enhanced bone purchase and bony fixation.

Resorptive Intramedullary Implant Between Two Bones or Two Bone Fragments

The invention relates to a resorptive intramedullary implant between two bones or two bone fragments. The implant includes a single-piece body (1) having a generally elongate shape and having, at each end, areas for anchoring to the bone portions in question, characterized in that one of said areas (A1) has a cylindrical cross-section while the other area (A2) has a flat cross-section.

Osseointegrable device

An implant arranged for integration into a skeletal bone of a patient, comprising: a body having at least one end, the body being arranged to substantially mimic a portion of a skeletal bone; wherein the at least one end includes an enlarged portion arranged to, in use, prevent migration of the implant into the flesh of a patient.

Non-volatile memory to store resettable data

A non-volatile memory (NVM) is to store data and a first password. The first password is to protect the data. A controller is to selectively enable interaction with the data based on authenticating the first password against a second password. A temporary region is to store the second password. The second password is discarded in response to a status change of the apparatus. The data, the first password, and the second password are resettable by the controller in response to a reset request to bypass the first password, such that the apparatus is restorable to an unused state without authenticating the first password.

Femoral Nail With Enhanced Bone Conforming Geometry

A femoral nail includes a proximal section, a distal section remote from the proximal section, and an intermediate section disposed between the proximal section and distal section and having first and second curved portions. The first curved portion is positioned closer to the proximal section than the second curved portion. The second curved portion is curved in a first plane, and the first curved portion is curved in the first plane and a second and third plane.
