A glenoid component for securement to a glenoid surface of a scapula comprises a body portion having a first surface adapted to contact the glenoid surface of a scapula and a second surface configured to receive the head portion of a humerus. The glenoid component further includes an anchor peg for penetrating the glenoid surface of the scapula so as to secure the body portion to the glenoid surface of the scapula. The anchor peg includes a cylindrical shaft extending from the first surface of the body portion and a fin secured to and extending outwardly from the cylindrical shaft. The glenoid component further includes a feature that prevents rotation of the glenoid component.

The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.

The methods disclosed herein of generating three-dimensional lattice structures and reducing stress shielding have applications including use in medical implants. One method of generating a three-dimensional lattice structure can be used to generate a structure lattice and/or a lattice scaffold to support bone or tissue growth. One method of reducing stress shielding includes generating a structural lattice to provide sole mechanical spacing across an area for desired bone or tissue growth. Some examples can use a repeating modified rhombic dodecahedron or radial dodeca-rhombus unit cell. Some methods are also capable of providing a lattice structure with anisotropic properties to better suit the lattice for its intended purpose.

The present invention relates to a prosthesis, such as a megaprosthesis, for a joint replacement or any segmental bone deficit. In particular, the present invention relates to a stem for a prosthesis having threads on at least part of an outer surface thereof. A prosthesis, such as a megaprothesis, is also provided. The prosthesis contains the threaded stem and a modular body engaged to the stem. The modular body contains a bone replace segment or a replacement joint, such as replacement knee joint, hip joint, shoulder joint, wrist joint, ankle joint, elbow joint, joints of the hand, joints of the foot, etc.

Provided herein are compositions and medical devices, and in particular, biodegradable scaffolds capable of repairing and replacing cartilagenous meniscuses. Also provided herein are methods of using scaffolds for treating degenerative tissue disorders. In certain embodiments, such scaffolds can promote tissue regeneration of a temporal mandibular joint (TMJ) meniscus.

The present invention relates generally to a prosthetic spinal disc for replacing a damaged disc between two vertebrae of a spine and methods for inserting said discs. The intervertebral prosthetic discs are provided with connections for facilitating implantation and removal and features which enhance primary and secondary stability over time.

A method of resurfacing a facet joint with a facet implant system. The facet joint includes a superior facet and an inferior facet that are adjacent to each other and movable with respect to each other. A first facet implant component is provided that has a first visualization marker. The first visualization marker includes a first marker section and a second marker section. The first marker section is oriented at an angle with respect to the second marker section. The first facet implant component between the superior facet and the inferior facet. A location and an orientation of the first facet implant component are determined using an imaging technique that locates the first visualization marker.

There is disclosed a hip implantation structure, comprising a stem and a femoral head, the femoral head comprising a plurality of grooves, an outer acetabular cup and an inner liner, wherein presence of the inner liner and plurality of grooves on the femoral head reduces friction and thereby reduces wear of the hip implantation structure. The hip implantation structure is used for total hip arthroplasty. The plurality of grooves on the femoral head comprises a plurality of hemispherical grooves of varying widths, and debris produced by the inner liner gets trapped inside the plurality of grooves, resulting in a reduced chance of adhesive wear.

Described is a femoral component of a prosthetic hip implant. The femoral component can include: a neck portion; and a stem portion including a proximal end and a distal end. The neck portion extends from the proximal end, and the stem portion comprises a first solid portion and at least one additional portion including at least one of a hollow portion, a porous portion, and a second solid portion comprised of a different solid material from a solid material of the first solid portion. The first solid portion and the at least one additional portion are in a predetermined configuration. The femoral component comprises a unitary component that is formed by additive manufacturing of the femoral component from a 3D model of the femoral component.

The invention discloses a support element for humeral implant comprising a central body extending along an axis and at least three arms extending outwardly from the central body, the arms being transversal to said axis and bearing a ring element at their ends opposite to said central body, wherein at least a first and a second pair of arms form different angles.
