20080281428 | METHODS AND APPARATUSES FOR ATTACHING SOFT TISSUE TO ORTHOPAEDIC IMPLANTS - Methods and apparatuses for attaching soft tissue and/or bone to orthopaedic implants. In one exemplary embodiment, the methods and apparatuses are used to attach soft tissue and/or bone to a proximal tibial implant. In another exemplary embodiment, the methods and apparatuses are used to attach soft tissue and/or bone to a proximal femoral implant. | 11-13-2008 |
20090192610 | ORTHOPEDIC COMPONENT OF LOW STIFFNESS - An orthopedic component having multiple layers that are selected to provide an overall modulus that is substantially lower than the modulus of known orthopedic components to more closely approximate the modulus of the bone into which the orthopedic component is implanted. In one exemplary embodiment, the orthopedic component is an acetabular shell. For example, the acetabular shell may include an outer layer configured for securement to the natural acetabulum of a patient and an inner layer configured to receive an acetabular liner. The head of a femoral prosthesis articulates against the acetabular liner to replicate the function of a natural hip joint. Alternatively, the inner layer of the acetabular shell may act as an integral acetabular liner against which the head of the femoral prosthesis articulates. | 07-30-2009 |
20090222007 | MODULAR STEM EXTENSION - The modular stem component may include a shaft portion, a head, and a sleeve. The shaft portion is configured for receipt within the intramedullary canal of a bone and the head is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib defining a flange extending therefrom. The sleeve, which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends and has a bore extending therethrough. The bore is configured to facilitate sliding receipt of the sleeve on the head. | 09-03-2009 |
20100143576 | DIRECT APPLICATION OF PRESSURE FOR BONDING POROUS COATINGS TO SUBSTRATE MATERIALS USED IN ORTHOPAEDIC IMPLANTS - A method for constantly controlling a direct application of pressure for bonding porous coatings to substrate materials used in orthopaedic implants. The direct pressure is applied to an interface between the porous coating and the substrate material via a pressure application mechanism unaffected by heat and air pressure conditions of the bonding process. The pressure application mechanism maintains a pressure on the implant which is constantly controlled throughout the bonding process. | 06-10-2010 |

20110230973 | METHOD FOR BONDING A TANTALUM STRUCTURE TO A COBALT-ALLOY SUBSTRATE - Methods for bonding a porous tantalum structure to a substrate are provided. The method includes placing a compressible or porous interlayer between a porous tantalum structure and a cobalt or cobalt-chromium substrate to form an assembly. The interlayer comprising a metal or metal alloy that has solid state solubility with both the substrate and the porous tantalum structure. Heat and pressure are applied to the assembly to achieve solid state diffusion between the substrate and the interlayer and the between the porous tantalum structure and the interlayer. | 09-22-2011 |
20120125896 | RESISTANCE WELDING A POROUS METAL LAYER TO A METAL SUBSTRATE - An apparatus and method are provided for manufacturing an orthopedic prosthesis by resistance welding a porous metal layer of the orthopedic prosthesis onto an underlying metal substrate of the orthopedic prosthesis. The resistance welding process involves directing an electrical current through the porous layer and the substrate, which dissipates as heat to cause softening and/or melting of the materials, especially along the interface between the porous layer and the substrate. The softened and/or melted materials undergo metallurgical bonding at points of contact between the porous layer and the substrate to fixedly secure the porous layer onto the substrate. | 05-24-2012 |
20130180970 | RESISTANCE WELDING A POROUS METAL LAYER TO A METAL SUBSTRATE - An apparatus and method are provided for manufacturing an orthopedic prosthesis by resistance welding a porous metal layer of the orthopedic prosthesis onto an underlying metal substrate of the orthopedic prosthesis.

20130031051 | ADDING A KEW COLUMN TO A TABLE TO BE REPLICATED - Techniques are disclosed for adding a key column to a table to be replicated, where the key column stores key values for use in replication. In one embodiment, a request is received to add a table to a replication domain, such that the table is replicated from a first database server to at least a second database server. Key values are generated for both existing records and new records subsequently requested to be inserted into the table, respectively. Each generated key value is unique across the replication domain. Further, the key column may be added to the table without requiring exclusive access to the table. | 01-31-2013 |
