Intact wedge fractures in the proximal third of the femoral shaft are classified as 32B2(a) fractures.
Transverse femoral shaft fractures occur due to direct bending force and can be caused by a direct impact or blow and are of moderate energy impact.
In intact wedge fractures there are three fragments, a proximal, a distal and a wedge fragment. After reduction there is some contact between the proximal and distal fragments. Wedge fractures often result from moderate injury to the femur. The mechanism is a bending force, usually three points.
