An orthopedic implant includes a metal core having a first end, a second end, a first elastic modulus, and a first porosity. A proximal body is fused directly onto the metal core between the first and second ends. The proximal body has a second elastic modulus, which is less than the first elastic modulus, and a second porosity, which is greater than the first porosity. The porosity of the proximal body may vary throughout.
