Medical Device Testing: Internal Fixation vs. External Fixation. External fixation is a surgical treatment used to set bone fractures in which a cast would not allow proper alignment of the fracture. An example of a standard test for external fixation is ASTM F1541. Internal fixation involves the surgical implementation of implants for the purpose of repairing a bone. Traditionally an internal fixator would be made of stainless steel or titanium, but now bioabsorbable bone screws, acrylic bone screws, and other composite materials are coming into the market.
The main physical distinction between screws and bolts is that screws are entirely full of threads while bolts contain shanks without threads. However, a better interpretation of the differences between the two is that bolts are always fitted with nuts. On the contrary, screws are normally used with tapped holes.
