Incomplete Fractures Greenstick
The fracture lies in a transverse or oblique plane across the cortex with cortical disruption on one side and deformity on the other, resulting in bowing of the bone.
Can only happen in young bone
Incomplete Fractures Fissure
Longitudinal or spiral fracture in the cortex with no significant bone displacement and no bending, also know as a hairline fracture
Mature bone (more brittle)
Depression Fractures
Complete FracturesTransverse
The fracture occurs perpendicular (at right angles) to the axis of the bone.
Complete FracturesOblique
The fracture is diagonal to the long axis of the bone.
Often prefaced with “short” or “long”
Complete FracturesSpiral
The fracture is a curve.
Due to torsional forces on bone
Lots of soft tissue damage.
Complete FracturesComminuted
The fracture has one or more completely separated fragments
High energy trauma
No inherent stability
Complete FracturesMultiple
at least 3 pieces of bone, but the fracture lines do not intersect
Complete FracturesImpaction
cortical bone wedged into cancellous bone
Rare in animals
Complete FracturesCompression
cancellous bone collapses in upon itself
this occurs in vertebral bodies following trauma to the spine
Closed vs. Open Fracture
CLASSIFICATION OF FRACTION BY LOCATIONMETAPHYSEAL FRACTURE
For a clearer description the terms proximal or distal should be added, such as a closed, oblique fracture of the distal femoral metaphysis.
Since most metaphyseal fractures are through cancellous bone, they generally heal rapidly.
Salter-Harris Type I Physeal separation resulting in displacement of the
epiphysis from the metaphysis at the growth plate.
Salter-Harris Type I
Called a “slipped cap” when on the head of the femur
Salter-Harris Type II A corner of the metaphyseal bone is fractured with
displacement of the epiphysis from the metaphysis at the growth plate.
Salter-Harris Type II
Salter-Harris Type III A fracture through the epiphysis and part of the
growth plate; the metaphysis is unaffected (articular fractures).
Salter-Harris Type III
Salter-Harris Type IV
A fracture through the epiphysis, growth plate, and metaphysis; several fracture lines may be seen (articular fractures).
Salter-Harris Type IV
Salter-Harris Type V A compression fracture of the physis: These fractures
can lead to premature closure of the physis resulting in abnormal growth and limb deformity. This is most commonly seen in the distal ulnar growth plate due to its conical morphology.
