A device for the repair of a phalangeal joint comprises a first anchor, a second anchor, and a flexible spacer connecting the first and second anchors. The flexible spacer comprises a plurality of elongate fibers extending axially or criss-crossed between the first and second anchors and a polymeric matrix interspersed with the plurality of elongate fibers. Specifically, a prosthetic metatarsophalangeal joint device comprises a porous metallic metatarsal bone anchor, a porous metallic phalangeal bone anchor, and a polymeric spacer element comprising parallel or criss-crossed elongate fibers that can connect the metatarsal bone anchor and the phalangeal bone anchor. Methods for manufacturing prosthetic joint devices comprise using three-dimensional printing processes or molding processes. Methods for implanting prosthetic joint devices comprise positioning porous metallic anchor components adjacent resected bones at planar interfaces and between which a polymeric spacer having axial aligned elongate fibers embedded in a matrix can be disposed.

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.

Described here are deformable, monolithic, stabilization implants suitable for use within bone and between bones to fuse vertebral bodies, to repair herniated discs, or to repair spinal compression fractures. The implants are introduced into a chosen site at a first, smaller height and then plastically deformed to achieve a second, but unique, pre-selected, larger height. Variations of the device provide one or more specific larger heights. The devices are suitable as intervertebral spinal fusion implants for the immobilization of adjacent vertebral bodies. Methods of and instruments for deployment of the implants are also described. Also described are variations of the device suitable as sizing instruments.

An expandable support device for tissue repair is disclosed. The device can be used to repair hard or soft tissue, such as bone or vertebral discs. A method of repairing tissue is also disclosed. The device and method can be used to treat compression fractures. The compression fractures can be in the spine. The device can be deployed by compressing the device longitudinally resulting in radial expansion.

An acetabular cup assembly for use with liners is described. The acetabular cup assembly includes a cup and a liner. The cup has an outer surface, a generally concave inner surface and a top face. The inner surface includes a cylindrical band having a plurality of inward-facing recessed scallops, a tapered wall adjacent to the band, and an inner spherical surface adjacent the tapered wall. The inner spherical surface has a substantially uniform radius of curvature. A single groove interrupts the spherical surface. The liner has a substantially convex outer surface and includes a rim and a plurality of outward-projecting scallops adjacent the rim. The scallops of the liner are configured to engage the scallops of the cup when the liner is seated in the cup. Related methods of use are also provided.

An orthopaedic knee implant includes a femoral component having a substrate and a coating disposed on the surface of the substrate. A method for making a femoral component of an orthopaedic knee implant is also disclosed.

An orthopaedic implant includes a tibial component having a metal base with a polymer bearing molded thereto. A method for making a tibial component is also disclosed.

Devices and methods for orthopedic support are disclosed. The device can have a first rigid section hingedly attached to a second rigid section. The device can be curved or rotated around obstructions along an access path to a target site. The device can be delivered to an intervertebral location in a patient.
