An adjustable spinal fusion intervertebral implant is provided that can comprise upper and lower body portions that can each have proximal and distal wedge surf aces disposed at proximal and distal ends thereof. An actuator shaft disposed intermediate the upper and lower body portions can be actuated to cause proximal and distal protrusions to converge towards each other and contact the respective ones of the proximal and distal wedge surfaces. Such contact can thereby transfer the longitudinal movement of the proximal and distal protrusions against the proximal and distal wedge surfaces to cause the separation of the upper and lower body portions, thereby expanding the intervertebral implant. The upper and lower body portions can have side portions that help facilitate linear translational movement of the upper body portion relative to the lower body portion.

A biodegradable joint implant comprises a joint scaffold and a film layer coated on the surface of the joint scaffold. The joint scaffold comprises a first anchor fixing, a second fixing and a flexible spacer, and the first anchor fixing and the second anchor fixing are respectively axially connected to opposite sides of the flexible spacer. The joint implant is made of biodegradable material, and the film layer contains at least one substance that can induce tissue growth. A method for preparing the joint implant and a joint replacement method using the joint implant are also provided.

An implantable composition, method of making and using the implantable composition is provided. The implantable composition comprising a first set of fibers and a second set of fibers, the first set of fibers manufactured to have a first binding surface, the second set of fibers manufactured to have a second binding surface, the first binding surface of the first set of fibers configured to bind at least at or near the second binding surface of the second set of fibers and the second set of fibers configured to bind at least at or near the first binding surface of the first set of fibers.

Provided are biocompatible and implantable scaffolds for treating a tissue defect, such as a bone gap. The scaffolds can have a modular design comprising a tissue scaffold rack designed to accommodate one or more modules. Also provided are methods for fabrication and use of such scaffolds.

The three-dimensional lattice structures disclosed herein have applications including use in medical implants. Some examples of the lattice structure are structural in that they can be used to provide structural support or mechanical spacing. In some examples, the lattice can be configured as a scaffold to support bone or tissue growth. Some examples can use a repeating modified rhombic dodecahedron or radial dodeca-rhombus unit cell. The lattice structures are also capable of providing a lattice structure with anisotropic properties to better suit the lattice for its intended purpose.

This disclosure relates to orthopaedic implant systems and methods for repairing bone defects and restoring functionality to a joint. The implant systems and methods disclosed herein may include augments extending from respective baseplates. The augments may have an internal network for communicating material in the respective implant.

Provided are a bone graft composition and a preparation method thereof, and more particularly, a bone graft composition provided in the form of a putty formulation by mixing calcium phosphate compound particles with hydrogel, having excellent physical properties, which is easy to inject, and which maintains its structure even in an in vivo environment after implantation, thereby enabling sustained release of a drug loaded therein.

The invention primarily relates to fastening and stabilizing tissues, implants, and/or bondable materials, such as the fastening of a tissue and/or implant to a bondable material, the fastening of an implant to tissue, and/or the fastening of an implant to another implant. This may involve using an energy source to bond and/or mechanically to stabilize a tissue, an implant, a bondable material, and/or other biocompatible material. The invention may also relate to the use of an energy source to remove and/or install an implant and/or bondable material or to facilitate solidification and/or polymerization of bondable material.

A medical product, preferably for use in the treatment, more particularly in the filling up and/or closure, of a bone cavity, the product having structural elements connected to one another, the structural elements being dividable at least into two groups of structural elements, namely at least into a first group of structural elements and into a second group of structural elements, the structural elements of the first group having a lower hardness than the structural elements of the second group. Furthermore, a method for producing the medical product and a medical kit.

The invention relates to an augmentation device comprising an annular cone surrounding a channel which extends through the cone from a proximal cone end to a distal cone end of said cone. The invention furthermore relates to a method for adapting a cone size of such an augmentation device.
