Anything that can replace human bones must be as hard as bones, so orthopedics often uses metal materials.
If these pieces didn't show up in a surgeon's box, at first glance, one might think they were machine parts.
A cylindrical shape that looks like a mesh closed together, this thing is called a Titanium Cage, a type of orthopedic material.
Just by looking at this structure, you know it belongs to a simple device, and indeed it is. It is the least complex supporting material in the fixed-type fusion artificial vertebrae structure. Since it does not have a height adjustment device, it cannot be adjusted during surgery, and its stability depends on conical spikes at the two ends. Surgeons can only assist in fixing it by adding titanium plates or a Screw-Rod System.
