Gartland's classification of supracondylar fractures in children

Gartland classified supracondylar fractures into 3 types. They are:

• Type I – Undisplaced
• Type II – Displaced, but posterior cortex is intact
• Type III – Displaced but posterior cortex is not intact. The distal fragment may be displaced in one of the 2 possible ways
  • Posteromedial
  • Posterolateral

Nerve injuries and other complications are more common in type III supracondylar fractures.
