Correct answer: E — Angle fracture
Mandibular angle fractures have the highest rate of post-operative complications (infection, malunion, plate failure) compared to other sites. This is attributed to: (1) the presence of impacted or partially erupted third molars in the fracture line acting as a source of contamination; (2) thin bone cross-section with less surface area for fixation; (3) unfavourable biomechanics (pull of masseter and medial pterygoid on the proximal segment); and (4) the angle being the weakest structural point of the mandible.
