Fig. 5From: Catastrophic failure of a titanium locking plate in a proximal humeral fracture: case report and literature reviewThe SEM images of A’ marked by red frame (magnification × 800) show fatigue striations, suggesting crack origination. The morphology of the yellow frames (magnification × 350) represents a fatigue crack propagation. Ductile dimples at the blue frame (magnification × 180) indicate a dynamic fracture region.
