An external fixator acts as a stabilizing frame to hold the broken bones in proper position. In an external fixator, metal pins or screws are placed into the bone through small incisions into the skin and muscle.n external fixator acts as a stabilizing frame to hold the broken bones in proper position.

Cockatoo Squid This transparent cockatoo squid (Leachia sp.), also known as a glass squid, lives in the depths of the ocean and has many adaptations to help it survive there. It retains ammonia solutions inside its body that give it a balloon-like shape and help it float.
The bulk of the ocean is deep-sea habitat with no light. Munidopsis albatrossae, a blind âsquat lobster,â lives at depths up to 2,500 meters. Because there is no light at this depth, they would have little use for eyes and therefore have none. Image courtesy of Exploring Alaska's Seamounts 2002, NOAA/OER.
