摘要：
Various different porous screws and pegs are disclosed herein, as are methods of manufacturing such porous pegs or screws. The porous screws and pegs, in certain examples, are formed through additive manufacturing and have improved porosity for bone ingrowth. In certain cases, additive manufacturing or another manufacturing technique can be used to cover only part or all of the threads of the screws or pegs disclosed herein with a porous material. Such screws or pegs can have porosity but also threads that are capable of effectively digging into bone.
