33-A: extra-articular; 33-B: partial articular (e.g., Hoffa = B3); 33-C: complete articular. Articular types require anatomic joint reduction; fixation usually with locking plates or retrograde nails.

What is the primary reason for the use of locking plates in the fixation of distal femur fractures?
What is the main characteristic of AO/OTA type 33-A fractures?
Which type of fracture is classified as 33-B in the AO/OTA system?
What is the preferred fixation method for a complex 33-A fracture with metaphyseal comminution?
In distal femur fractures, which muscle primarily causes posterior displacement of the distal fragment?
Which of the following statements about AO/OTA type 33-C fractures is true?
What is the primary goal in the surgical management of distal femur fractures?
Which of the following is a common complication of distal femur fractures?
