32-A2 Simple oblique fractures of the femoral diaphysis
32-A2 are simple oblique fractures of the femoral diaphysis. Spiral fractures are not explicitly included in this classification. However, as their treatment is often similar they will be included for this reference under A2 type fractures. Spiral and oblique fractures are usually caused by torsional forces. They typically occur after a sudden turn during running, while playing.
Oblique fractures can be subcategorized as “short oblique” (fracture line is between 30° and 60° relative to the long axis of the bone) and “long oblique” fractures (<30° relative to the long axis of the bone).
32-A type fractures are simple or incomplete fractures of the femoral diaphysis. They generally result from low energy trauma.
