摘要:
An orthopaedic augment includes a porous material, which is removably attached to a medical implant. The porous material has a bone ingrowth surface for interfacing with an existing bone material and another surface for interfacing with the medical implant.
摘要:
The present invention provides an orthopaedic implant including a base device having a device surface and a fixation material attached to at least one portion of the device surface. The fixation material is configured to provide a minimally sufficient adhesive force to resist natural pull out caused by forces acting on the base device after implantation and bone growth. Also provided is a method of manufacturing an orthopaedic implant. A base device with a device surface is provided and a minimally sufficient adhesive force, that can resist natural pull out caused by forces acting on the base device after implantation and bone growth, is determined. A proper amount of fixation material sufficient to provide an adhesive force equal to the minimally sufficient adhesive force is determined and fixation material is applied to the device. When the proper amount of fixation material is applied to the device surface, application is stopped.
摘要:
A three-dimensional scaffold for a medical implant includes a plurality of layers bonded to each other. Each layer has a top surface and a bottom surface and a plurality of pores extending from the top surface to the bottom surface. Each layer has a first pore pattern of the pores at the top surface and a different, second pore pattern at the bottom surface. Adjacent surfaces of at least three adjacent layers have a substantially identical pore pattern aligning to interconnect the pores of the at least three adjacent layers to form a continuous porosity through the at least three adjacent said layers.

A method of manufacturing a tubular medical implant is provided. The method includes forming a hollow first tube with a first diameter and a first plurality of pores formed thereon and a hollow second tube with a second unstretched diameter and a second plurality of pores formed thereon. The second unstretched diameter is greater than the first diameter. At least a portion of the first tube slides within the second tube to create an overlapped area of the first tube and the second tube. The first tube and second tube are then bonded together in the overlapped area.
摘要:
The present invention provides an orthopaedic screw comprising a main body having a torqueing end, an inner chamber formed therein, and at least two mating features separated by a separation gap, said separation gap extending into said inner chamber; and a support member removably placed in said inner chamber of said main body and having a support portion at least partially filling said separation gap between said at least two mating features.
