Final answer:
ORIF is utilized for all Type A1, A2, and A3 fractures as it involves surgical correction and stabilization of complex fractures typically not suitable for non-surgical methods such as closed reduction.
Step-by-step explanation:
The student asked, what kind of Type A fractures do we fix with ORIF (Open Reduction and Internal Fixation)? The answer is 4) All of the above, as Type A fractures refer to different types of fractures based on their location and complexity, including Type A1, Type A2, and Type A3 fractures. These fractures can be addressed with open reduction, which involves surgical intervention to reset the bone, as compared to closed reduction, where the bone is manipulated back into place without the need for surgery. ORIF is often employed when fractures are severe, involving multiple fragments or when they are displaced, requiring hardware (like screws or plates) to hold the bone fragments in place for proper healing.
