Provided herein are implants and methods for producing implants. In at least one embodiment, the implants include sheet-based, triply periodic, minimal surface (TPMS) portions. According to one embodiment, the TPMS portions include a gyroid architecture that provides for improved osseointegration and mechanical performance over previous implants due to novel ratios of porosity to compressive strength, among other features. In one or more embodiments, the gyroid architecture is organized into unit cells that demonstrate anisotropic mechanical performance along an insertion direction. In various embodiments, the present methods include novel selective laser melting (SLM) techniques for forming the TPMS portions of implants in a manner that reduces defect formation, thereby improving compressive performance and other implant properties.

A method of repairing a fractured bone may include implanting a prosthetic stem into an intramedullary canal of the fractured bone. First and second bone segments of the fractured bone may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the first end of the prosthetic stem. The first and second tuberosities may be machined so that the first and second bone segments have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the first end of the prosthetic stem, and the first interlocking surface interlocks with the second interlocking surface.

A medical honeycomb structure lacking at least a portion of an outer peripheral side wall of a honeycomb structure that includes a plurality of through-holes extending in one direction, wherein sites lacking the outer peripheral side wall have a plurality of grooves, and have a plurality of planes including distant surfaces of groove side walls flanked by the grooves.

Implants are provided. In one exemplary embodiment, an implant includes a spacer configured to be implanted within a joint. The spacer includes an elongated central body extending from a first end to a second end with a longitudinal axis extending therebetween, and first and second wings extending from the first and second ends of the elongated central body, respectively. The elongated central body has a first maximum height in a direction transverse to the longitudinal axis, and each of the first and second wings has a maximum height greater than the first maximum height. When implanted and in the inflated state, at least one of the first wing and the second wing is configured to mechanically interlock with a portion of the anatomy to thereby self-anchor the spacer to the joint and inhibit migration of the spacer. Implant systems and methods for biomechanically augmenting muscle function are also provided.

In order to promote bone growth without damage of a growth plate to improve the stability of a procedure, provided is an implant device for promoting bone growth, the device including: a first implant bar implanted to penetrate a metaphysis corresponding to the inside of a growth plate of a long bone to be treated; a second implant bar implanted to penetrate an epiphysis of the outside of the growth plate; and a stimulation elongation means disposed close to the external surface of the long bone to be treated and installed under skin tissues surrounding the long bone to be treated, and being elongated between end portions of the implant bars to increase a gap between the implant bars to cause the growth plate to be extended.

An implantable medical device is disclosed comprising a thermoplastic composite body having anterior, first lateral, second lateral, posterior, superior, and inferior surfaces, and at least one dense portion and at least one porous portion which are integrally formed. The at least one dense portion is formed of a first thermoplastic polymer matrix that is essentially non-porous, and which is continuous through a thickness dimension from the superior surface to the inferior surface. The at least one porous portion is formed of a porous thermoplastic polymer scaffold having a second thermoplastic polymer matrix which is continuous through the thickness dimension. A method for forming the thermoplastic composite body is disclosed comprising disposing a first powder mixture in a first portion of a mold, disposing a second powder mixture in a second portion of the mold, simultaneously molding the first powder mixture and the second powder mixture, and leaching porogen.

The invention features a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

An implant may include a body having a first portion and a second portion and a structural member having a central member curve. In addition, the structural member may be exposed on an outer surface of the implant. Further, the central member curve may include a winding segment, and the winding segment of the central member curve may wind around a fixed path extending from the first portion of the body to the second portion of the body. Also, the central member curve may make one or more full turns around the fixed path. And, the structural member may have a member diameter at the winding segment, wherein the winding segment has a winding diameter corresponding with the full turn around the fixed path and the member diameter is greater than the winding diameter.

A biological implant is implantable in a base being a part of a living organism. The implant includes an implant body including at least an outer circumferential surface containing a titanium alloy. The implant body is implantable in the base. Based on a first curve indicating a profile of the surface of the implant body obtained with a measurement length of 25.4 .Math.m and a second curve obtained by removing a long-wavelength component from the first curve at a cutoff value of 5 .Math.m in image processing performed on an image of a cut surface of the implant body perpendicular to the outer circumferential surface of the implant body, an arithmetic mean roughness value as a surface roughness value Ra of the outer circumferential surface calculated using the second curve is greater than or equal to 0.2 .Math.M.

The invention relates to a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.
