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.

A bone implant holding and shaping tray is provided. The tray includes a first segment having a distal end and a first surface sized to hold and shape at least a portion of the bone implant with bone material. The tray includes a second segment having a second surface sized to hold and shape at least a portion of the bone implant with bone material, the second segment having a proximal end configured to be coupled to the distal end of the first segment so as to extend the first surface to hold and shape the bone implant. Methods of making and using the bone implant holding and shaping tray are also provided.

Medical implant surface treatments and methods are described. Such a surface treatment may provide an uneven texture that is configured to interlock with adjoining bone and/or an uneven texture on another implant, such as an augment for an acetabular cup for revision hip surgery. At least one of the uneven texture of the cup bone-facing surface and the uneven texture of the augment cup-facing surface may include a web of rods. The rods may be configured to interlock with each other when the two implants are urged together.

A system, comprises an implant including an outer sleeve and a head element, the outer sleeve extending longitudinally and including a channel extending therethrough, the head element including a shaft portion and a bone-engaging portion, the shaft portion received within the channel of the outer sleeve and longitudinally movable relative thereto and a clip device removably assembled with the implant to hold the outer sleeve and the head element in a desired position relative to one another, the clip device including a body extending longitudinally along with a separation portion connected to a proximal end of the body via a releasable connection to engage the proximal end of the outer sleeve and a spacer portion connected to the proximal end of the body to releasably engage a portion of the shaft portion between a proximal end of the bone-engaging portion and the distal end of the outer sleeve.

An implant has a soft tissue attachment structure, and a surface defining a trough. An ingrowth plate spans a portion of the trough and defines a suture tunnel between the ingrowth plate and the trough for receiving suture. The ingrowth plate bows convexly away from the surface and is perforated to facilitate long-term ingrowth and biologic fixation of soft tissue to the implant.

One aspect of the present disclosure provides a method of manufacturing an orthopedic prosthesis. This particular method includes providing a porous metal layer (22) positioned against a metal substrate at an interface between the porous metal layer and the metal substrate. Additional steps include providing an electrode (132) and providing an intermediate element or coating positioned between and in contact with the electrode and the porous metal layer where the intermediate element includes tantalum in contact with tantalum of the porous metal layer. In a further step, an electrical current is directed to the interface between the porous metal layer and the metal substrate to bond the porous metal layer to the metal substrate.

An implant having a porous layer and a molding method thereof includes: a substrate having a bone contact surface being in part in direct contact with a bone of a patient; a porous layer having a void inside; a connecting layer disposed between the bone contact surface and the porous layer to attach the bone contact surface to the porous layer; and a rib detachably coupled to the porous layer, wherein the connecting layer includes at least one constituent component identical to one of constituent components in the bone contact surface to be integrated into the porous layer and the bone contact surface, thereby firmly attaching the porous layer to the bone contact surface. Accordingly, bonding of dissimilar metals is facilitated by inducing the attachment of the bone contact surface of the implant to the porous layer having a void inside, formed by dissimilar metals, through the connecting layer including at least one constituent component identical to one of constituent components of the bone contact surface.

An apparatus including a joint spacer for treatment of a joint of a human subject. The joint spacer includes a bioresorbable stent having compressed and expanded configurations and a covering that covers an external surface of the stent. The joint spacer is configured to be inserted into a space of the joint, and is shaped, when the bioresorbable stent is in the expanded configuration, to provide mechanical support to the joint until the bioresorbable stent resorbs into a body of the subject. Treating a joint of a human subject includes inserting a joint spacer into a space of the joint while a bioresorbable stent of the joint spacer is in a compressed configuration, and transitioning the bioresorbable stent to an expanded configuration within the joint, such that the joint spacer provides mechanical support to the joint until the bioresorbable stent resorbs into a body of the subject.

A sleeve for use with a percutaneous, external fixation device is disclosed, wherein the sleeve includes a sleeve body with an interior space in which the percutaneous device can be disposed, a flange that extends at a substantially perpendicular angle to the sleeve body, and a cutting edge extending from the sleeve body below the flange. The cutting edge is designed for placement in contact with the skin adjacent to the percutaneous device so as to define a leading edge thereof in a primary anticipated direction of migration of the percutaneous device. Kits and assemblies that include sleeves and percutaneous devices are also disclosed. Further disclosed are methods of reducing tension in a patient's skin following placement of the percutaneous device via use of the sleeve, as well as methods of adjusting and readjusting the assembly upon placement.

Medical implant surface treatments and methods are described. Such a surface treatment may provide an uneven texture that is configured to interlock with adjoining bone and/or an uneven texture on another implant, such as an augment for an acetabular cup for revision hip surgery. At least one of the uneven texture of the cup bone-facing surface and the uneven texture of the augment cup-facing surface may include a web of rods. The rods may be configured to interlock with each other when the two implants are urged together.
