An additively manufactured medical implant, comprising a metallic body having at least one porous surface configured to promote bony on-growth or in-growth of tissue, the porous surface being replicated from a high resolution scan of bone, and a biological surface coating configured to create a barrier to particulate debris, the biological surface coating being produced from a titanium porous plasma spray surface coating or a biomimetic coating.

Metallic structures having porous regions from imaged bone at pre-defined anatomic locations

A method of manufacturing a joint implant for a joint of a specific patient includes obtaining a three-dimensional image of a bone of the joint of the specific patient from medical imaging scans of the bone of the patient and determining on the three-dimensional image a resection plane for contacting a corresponding planar surface of the joint implant for the specific patient. The method includes determining a three-dimensional image of a porous structure of a bone layer along the resection plane from the medical imaging scans of the patient. The joint implant is manufactured with a layer of a patient-specific porous construct attached to the planar surface of the joint implant. The layer of the patient-specific porous construct substantially replicates the porous structure of the bone layer of the specific patient.

Implant with patient-specific porous structure

An osteotomy implant including a porous portion, a solid portion, and a hinge portion. The porous portion includes a first part and a second part that defines a clearance therebetween. A solid portion abuts the porous portion. A hinge portion of the solid portion is coupled to the first part and the second part. The hinge portion is configured to enable the implant to be changed from a first configuration to a second configuration.

Method and apparatus for pre-forming a high tibial osteotomy

A method for preparing an implant having a porous metal component. A loose powder mixture including a biocompatible metal powder and a spacing agent is prepared and compressed onto a metal base. After being compressed, the spacing agent is removed, thereby forming a compact including a porous metal structure pressed on the metal base. The compact is sintered, forming a subassembly, which is aligned with a metal substrate portion of an implant. A metallurgical bonding process, such as diffusion bonding, is performed at the interface of the subassembly and the metal substrate to form an implant having a porous metal component.

Method of bonding porous metal to metal substrates

A method of forming an implant having a porous region replicated from scanned bone, the method comprising imaging bone with a high resolution digital scanner to generate a three-dimensional design model of the bone; removing a three-dimensional section from the design model; fabricating a porous region on a digital representation of the implant by replacing a solid portion of the digital implant with the section removed from the digital representation; and using an additive manufacturing technique to create a physical implant including the fabricated porous region.

A ceramic implant having a rough surface texture and a method for forming the same. The method includes forming a green body of a first ceramic composition. The green body is reduced to smaller pieces thereby forming ceramic fragments. A mold is filled with a second ceramic composition to form a ceramic base. Ceramic fragments are added to the mold and an outer layer is formed over at least a portion of the ceramic base. Pressure is applied to the mold to compress the outer layer onto the ceramic base and to form a green assembly. The green assembly is sintered to form a ceramic implant having a rough surface texture.
