Q

what are the different types that tibial shaft fracture can be?

A
  • Nondisplaced: a fracture where the broken bones remain aligned. This type of fracture is usually seen in children under four.
  • Displaced, noncomminuted: a fracture where the bones are broken in no more than two pieces (noncomminuted) but are not aligned. This is an isolated fracture of the tibia shaft with an intact fibula. It is the most common tibia shaft fracture.
  • Displaced, comminuted: a fracture where the bones are broken in several fragments and not aligned.
