An implant for a human includes a body having a superior surface, an inferior surface, a distal surface, and a proximal surface. The proximal surface is configured to engage the talus and the calcaneus of an adult human, and the distal surface configured to engage at least the first and fourth metatarsals of the adult human. The distal surface has a largest distal height and a largest distal width that is greater than the largest distal height, and the proximal surface has a largest proximal height and a largest proximal width that is greater than the largest proximal height.

Graft collection and containment system for bone defects

A device for containing bone graft material comprises a body including an inner sleeve extending longitudinally from a proximal end to a distal end and an outer sleeve surrounding the inner sleeve and extending longitudinally from a proximal end to a distal end such that a bone graft collecting space is formed therebetween.

Systems and methods for attaching soft tissue to an implant

An implant has a soft tissue attachment structure, and a surface defining a trough. An ingrowth plate spans a portion of the trough and defines a suture tunnel between the ingrowth plate and the trough for receiving suture. The ingrowth plate bows convexly away from the surface and is perforated to facilitate long-term ingrowth and biologic fixation of soft tissue to the implant.

TALUS FORMATION AND IMPLANTATION METHOD

A process for printing a talus implant comprising the steps of scanning a joint for a damaged talus, and scanning a contralateral joint for a healthy talus. Next, the process includes obtaining dimensions for a talus based upon an initial scan and then obtaining dimensions for a talus based upon the scan of the contralateral joint. Next the process includes inverting the dimensions of the talus in the contralateral joint and then comparing the dimensions of the calculated talus with a pre-set of dimensions in a database. Next the process includes exporting a set of dimensions to a printer to print a talus implant.

TALUS IMPLANT

At least one embodiment comprises a talus implant comprising: a body section; a neck section; a crown, wherein the crown is positioned at a top portion of the body section; at least one wing coupled to the body section, wherein the wing extends out from the body section. At least one embodiment further comprises at least one screw hole positioned in at least one of the neck section and the body section. In at least one embodiment the outer surface of the implant is polished. In at least one embodiment a portion of the outer surface is polished while a portion of the outer surface is roughened.

Resistance welding a porous metal layer to a metal substrate utilizing an intermediate element

One aspect of the present disclosure provides a method of manufacturing an orthopedic prosthesis. This particular method includes providing a porous metal layer (22) positioned against a metal substrate at an interface between the porous metal layer and the metal substrate. Additional steps include providing an electrode (132) and providing an intermediate element or coating positioned between and in contact with the electrode and the porous metal layer where the intermediate element includes tantalum in contact with tantalum of the porous metal layer. In a further step, an electrical current is directed to the interface between the porous metal layer and the metal substrate to bond the porous metal layer to the metal substrate.

Implant having porous layer and molding method thereof

An implant having a porous layer and a molding method thereof includes: a substrate having a bone contact surface being in part in direct contact with a bone of a patient; a porous layer having a void inside; a connecting layer disposed between the bone contact surface and the porous layer to attach the bone contact surface to the porous layer; and a rib detachably coupled to the porous layer, wherein the connecting layer includes at least one constituent component identical to one of constituent components in the bone contact surface to be integrated into the porous layer and the bone contact surface, thereby firmly attaching the porous layer to the bone contact surface. Accordingly, bonding of dissimilar metals is facilitated by inducing the attachment of the bone contact surface of the implant to the porous layer having a void inside, formed by dissimilar metals, through the connecting layer including at least one constituent component identical to one of constituent components of the bone contact surface.

BIONIC ARTIFICIAL HIP JOINT
20210045882 · 2021-02-18 ·

The invention discloses a bionic artificial hip joint. The artificial hip joint includes a femoral stem located above corpus femoris, and a convex force-bearing part is provided on the femoral stem. The force-bearing part abuts against the inner side of the cortex on greater trochanter and bears a part of the longitudinal stress; its hollow design is convenient for bone grafting, so that the prosthesis and the greater trochanter can be integrated. Replacement surgery can preserve the hard cortex on the greater trochanter, providing another focus point for the femoral stem and further improving the stability of the connection between the bionic artificial hip joint and corpus femoris.

Medical implants disclosed herein may include an interior space and at least one bone on-growth structure within the interior space. The bone on-growth structure may include a root coupled to an interior surface of the implant, or to a mesh insert disposed within the interior space of the implant. The root may extend into the interior space toward another opposing interior surface of the implant. The bone on-growth structure may include a plurality of branches coupled to the root via a plurality of junctions. The plurality of branches may project at a plurality of different angles with respect to the root. The plurality of branches may each terminate within the interior space, or alternatively, one or more branches may contact opposing interior surfaces of the implant. The medical implants may also include one or more channels to enhance bone growth within the interior space.

IMPLANTABLE CONTAINMENT APPARATUS
20210059821 · 2021-03-04 ·

An implant containment apparatus for use with an implant device that defines a cavity that contains a bone graft material, and an implant tool selectively attached to the implant device, the implant containment includes a sack that defines a compartment and an opening that provides access to the compartment, where the compartment is adapted to contain the implant device with bone graft in the cavity and where the opening is adapted to allow the implant tool to extend out of the sack when the implant device is in the compartment, and a pre-attached closing member surrounding the opening adapted to selectively vary the size of the opening between a size that tightly fits around the implant tool and a size that closes the opening.
