Open fracture
- correct answer Skin broken
Closed fracture
- correct answer Skin not broken
Simple fracture
- correct answer Single break, maintaining alignment and position
Comminuted fracture
- correct answer Multiple fractures and bone fractures
,Compression fracture
- correct answer Bone crushed or collapsed into small pieces
Impacted fracture
- correct answer One end forced into adjacent bone
Pathologic fracture
- correct answer results from weakness; occurs with little stress
Stress fracture
- correct answer Fatigue fractures
Depressed fractures

Hematoma
- correct answer Clot form (homeostasis)
Granulation
- correct answer Tissue-inflammation response
Fibrocartilaginous callus
- correct answer Procallus
,Bony callus
- correct answer Replacing procallus
Factors affecting bone healing
- correct answer -Amount of local damage
-Proximity to bone ends
