Q

Types of fractures

A

COMPLETE – fracture extends all the way through bone

  • Closed – no break in skin
  • Open – break in skin
  • Transverse – right angle to shaft
  • Oblique – angle to shaft

· Eg Toddler’s fracture – oblique tibial fracture in infants

  • Spiral – twisting
  • Segmental – more than one fracture along bone
  • Comminuted – 2+ bone fragments
  • Compression – involving vertebrae in spine
  • Impacted – fractured bone forced together

INCOMPLETE (not all the way through cortex) – commonly children

  • Greenstick – bending of shaft, fracture on convex surface
  • Buckle (torus) – fracture of shaft of bone characterised by bulging of cortex
  • Salter-Harris – involving growth plate
  • Bowing – bend in bone shaft – plastic deformity
