A device is for containing a bone graft material. The device includes a mesh outer sleeve extending longitudinally from a proximal end to a distal end and sized and shaped to correspond to a profile of an outer surface of a target bone. The outer sleeve includes a plurality of openings extending therethrough, longitudinally adjacent ones of the plurality of openings being offset from one another relative to a longitudinal axis of the device. The device also includes a mesh inner sleeve connected to an interior surface of the outer sleeve via at least one strut so that a bone graft collecting space is defined therebetween The inner sleeve is sized and shaped to correspond to a profile of a medullary canal of the target bone. The inner sleeve includes a plurality of openings extending therethrough.

Mobile prosthesis for interpositional location between bone joint articular surfaces and method of use
09814581 · 2017-11-14 ·

A biocompatible prosthetic device comprising a thin low friction spacer for location to overlie a bone member in an interpositional location between opposed bone joint articular surfaces. The prosthesis is preferably a thin spacer with at least one low friction surface, the spacer being adapted for location about a bone member in an interpositional location between opposed bone joint articular surfaces preferably about a margin of articular cartilage of a bone member's condyle, preferably without any modification of the articular surface of the condyle. One preferred use of a prosthesis is in a human temporomandibular joint as a thin cap-like member fitted closely over the mandibular condyle to be disposed intermediate of the mandibular condyle and the mandibular fossa of the temporomandibular joint.

PROSTHETIC IMPLANT FOR BALL AND SOCKET JOINTS AND METHOD OF USE

A hip prosthesis includes an acetabular cup and a femoral component comprising a head and a stem, wherein the stem comprises a truss structure, the truss structure comprising a space truss comprising a plurality of planar truss units having a plurality of struts joined at nodes, wherein the web structure is configured to interface with bone tissue.

IMPLANT COMPONENTS AND METHODS

Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. Mounting members include, for example, flanges, blades, hooks, and plates. In some embodiments, the orthopedic attachments may be adjustably positionable about the base member or other attachments, thereby providing modularity for assembling and implanting the device, and various securing and/or locking mechanisms may be used between the components of the implant.

Retention devices, lattices and related systems and methods

A woven retention device that is configured to receive a fastener in a bone hole can be configured to promote bone ingrowth and impede biofilm formation. The woven retention device can be made of woven filaments that outline apertures of varying sizes and shapes and can serve as an interface between the fastener and the bone material. In a first relaxed state, the interwoven filaments can outline apertures of varying sizes and shapes within a predetermined range and in a second constricted state inside the bone hole with the fastener the interwoven filaments can outline apertures of decreased area that still fall within the predetermined range. The woven retention device can be configured to allow for optimal bone growth while at the same time minimizing the likelihood that biofilm forms thereon.

Laser-Produced Porous Surface

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.

Implants for spinal fixation and or fusion

The present invention generally relates to bone implants. More specifically, the present invention relates to bone implants used for the fixation and or fusion of the sacroiliac joint and/or the spine. For example, a system for fusing and or stabilizing a plurality of bones is provided. The system includes an implant structure having a shank portion, a body portion and a head portion. The body portion is coupled to the shank portion and is configured to be placed through a first bone segment, across a bone joint or fracture and into a second bone segment. The body portion is configured to allow for bony on-growth, ingrowth and through-growth. The head portion is coupled to the proximal end of the shank portion and is configured to couple the shank portion to a stabilizing rod. Methods of use are also disclosed.

Interbody spacer for spinal fusion
11357632 · 2022-06-14 · ·

An interbody spacer for spinal fusion surgery includes first and second opposite side walls that have open-cell metal foam at upper and lower faces, and a three-dimensional lattice disposed between open-cell metal foam at the upper and lower faces. The open-cell metal foam is in communication with the three-dimensional lattice so that bone growth can enter the three-dimensional lattice from the open-cell metal foam. The interbody spacer may be formed by additive manufacturing.

HYBRID FIXATION FEATURES FOR THREE-DIMENSIONAL POROUS STRUCTURES FOR BONE INGROWTH AND METHODS FOR PRODUCING

An orthopaedic prosthetic component comprises a fixation peg including a porous three-dimensional structure configured to permit bone in-growth. The porous three-dimensional structure has an outer surface boundary. The fixation peg includes a plate attached to the porous three-dimensional structure at the outer surface boundary. The plate includes a tapered body having an outer wall that faces away from the porous three-dimensional structure and is devoid of any openings.
