First off is the non-displaced fracture. This is where the bone ends retain their normal position.
Displaced fracture- bone ends are out of normal alignment
Complete fracture- bone is all the way through
Incomplete- bone is not broken all the way through
Linear fracture- the fracture is parallel to the long axis of the bone
Transverse fracture- fracture is perpendicular to the long-axis of the bone
compound (open)- bone ends penetrate the skin
Simple Fracture- Bone ends do not penetrate the skin
Comminuted fracture- bone fragments in three or more pieces; common in elders
Spiral fracture- ragged brake when bone is excessively twisted; very common sports fracture
Depression fracture: broken bone portion pressed inward; typical skull fracture
Compression Fracture-bone is completely crushed
Epiphyseal: epiphysis separates from diaphysis along epiphyseal line;
occurs where cartilage cells are dying
Above are a brief description and a picture of the different types of fractures. I would have to say that personally, I think the open fracture is the most nasty. I have been very fortunate and have only broken my index finger throughout my 18 years of life. Although, it was probably considered and "open fracture", it wasn't nearly as severe are the one picture above. YUCKKKKK! It is really interesting to me to see all these different pictures and learn about our bone and the types of things that can happen to them.
