Abstract

Abstract Disclosed is an orthopedic implant suitable for arthroplasty procedures. The orthopedic implant includes a first plate, a second plate, an axial support between the first plate and the second plate and one or more torsional supports connecting the first plate and the second plate. The axial support may be, for example, one or more flexible struts, such as cables, or a ball and socket joint. The torsional supports connect the first and second plates and may be, for example, curved around the axial support. The torsional supports may be integrally formed with the first and second plates as a single unitary device, by, for example, a Laser Engineered Net Shape (LENS) process.
