Orthopedic implants having improved strength and imaging characteristics are provided. The implants can comprise an inner core member that is encased at least in part by an outer encasing member. The inner core member can be formed of a first material that imparts improved strength to the implant, while the outer encasing member is formed of a second material that imparts improved imaging characteristics to the implant. Alternatively, the implants can include a single-piece member formed of a first material that is coated by a coating layer of a second material.
