摘要：
Systems and methods for forming an insert, such as a threaded or threadable insert, within a cavity in an implant, such as a spinal spacer. According to various embodiments, a spinal interbody spacer may include a proximal end and a distal end. The interbody spacer may be manufactured using a non-threadable material, or at least a material that is difficult to thread, such as a ceramic, a glass, or a porous material. Some embodiments may comprise a silicon nitride ceramic material. A cavity may be formed in the interbody spacer, such as in the proximal end. A material having desired properties lacking in the spacer, such as a threadable insert within a non-threadable spacer, may be inserted into the cavity. The threadable material may then be threaded in order to form a female-threaded insert within the otherwise non-threadable interbody spacer.
