A method of forming a spinal implant for implantation into a human body, the method comprising: providing a spinal implant workpiece having a first end surface, an opposite second end surface, a first lateral side surface, an opposite second lateral side surface, an upper surface, and a lower surface; providing at least one mold portion including at least one surface configured for contacting at least one of the first end surface, the second end surface, the first lateral side surface, the second lateral side surface, the upper surface, and the lower surface, the at least one surface of the at least one mold portion including surface structures for correspondingly creating surface structures on the at least one of the first end surface, the second end surface, the first lateral side surface, the second lateral side surface, the upper surface, and the lower surface; positioning granules between the at least one surface of the at least one mold portion and at least one of the first end surface, the second end surface, the first lateral side surface, the second lateral side surface, the upper surface, and the lower surface; heating the at least one mold portion and/or the spinal implant workpiece; pressing the granules via physical force of the at least one surface of the at least one mold portion against the at least one of the first end surface, the second end surface, the first lateral side surface, the second lateral side surface, the upper surface, and the lower surface to incorporate the granules into the spinal implant workpiece so that the granules extend from the at least one of the first end surface, the second end surface, the first lateral side surface, the second lateral side surface, the upper surface, and the lower surface into the spinal implant workpiece; and forming a surface configuration on the at least one of the first end surface, the second end surface, the first lateral side surface, the second lateral side surface, the upper surface, and the lower surface corresponding to the surface structures formed on the at least one surface of the at least one mold portion. providing a spinal implant workpiece having a first end surface, an opposite second end surface, a first lateral side surface, an opposite second lateral side surface, an upper surface, and a lower surface; providing at least one mold portion including at least one surface configured for contacting at least one of the first end surface, the second end surface, the first lateral side surface, the second lateral side surface, the upper surface, and the lower surface, the at least one surface of the at least one mold portion including surface structures for correspondingly creating surface structures on the at least one of the first end surface, the second end surface, the first lateral side surface, the second lateral side surface, the upper surface, and the lower surface; positioning granules between the at least one surface of the at least one mold portion and at least one of the first end surface, the second end surface, the first lateral side surface, the second lateral side surface, the upper surface, and the lower surface; heating the at least one mold portion and/or the spinal implant workpiece; pressing the granules via physical force of the at least one surface of the at least one mold portion against the at least one of the first end surface, the second end surface, the first lateral side surface, the second lateral side surface, the upper surface, and the lower surface to incorporate the granules into the spinal implant workpiece so that the granules extend from the at least one of the first end surface, the second end surface, the first lateral side surface, the second lateral side surface, the upper surface, and the lower surface into the spinal implant workpiece; and forming a surface configuration on the at least one of the first end surface, the second end surface, the first lateral side surface, the second lateral side surface, the upper surface, and the lower surface corresponding to the surface structures formed on the at least one surface of the at least one mold portion.
