Imaging of pediatric musculoskeletal trauma: Age-specific considerations and challenges

Table 2 Gartland classification

Type	Description	Subtypes
I	Undisplaced or minimally displaced (< 2 mm)	Ia: Undisplaced in both projections; Ib: Minimal displacement, medial cortical buckle, anterior humeral line intersects capitellum
II	Displaced but with intact cortex	IIa: Posterior angulation, intact posterior cortex, anterior humeral line does not intersect capitellum; IIb: Rotatory or straight displacement, fracture ends remain in contact
III	Completely displaced	IIIa: Complete posterior displacement, no cortical contact; IIIb: Complete displacement with soft tissue gap (bone ends separated by soft tissue)
IV	Displaced, unstable in flexion and extension, periosteal disruption (diagnosed intra-operatively)	NA

NA: Not available.
