Diagnosis

Simple fracture, oblique ≥ 30° (AO/OTA 32A2)

print

Simple oblique fractures often result from medium to moderate injury to the femur. Slightly more energy is needed to cause an oblique fracture as compared to a spiral fracture.
This fracture is exemplified by a fracture angle of more than 30°.

Options
1. Proximal 1/3 (AO/OTA 32A2(a)) 
2. Middle 1/3 (AO/OTA 32A2(b)) 
3. Distal 1/3 (AO/OTA 32A2(c)) 

1. Proximal 1/3 (AO/OTA 32A2(a)) 

(AO/OTA 32A2(a))

(AO/OTA 32A2(a))

Simple oblique fractures in the proximal third of the femoral shaft are classified as 32A2(a) fractures.

(AO/OTA 32A2(b))

Simple oblique fractures in the mid third of the femoral shaft are classified as 32A2(b) fractures.
