Data are presented in mm. AL: Posterosuperior fracture line vertical to the ground surface; BL: Posterior wall fracture line horizontal to the ground; CL: Posteroinferior fracture line vertical to the ground surface; CCRP: Conventional curved reconstruction plate; L: Left hemipelvis; PABP: Precontoured anatomical buttress plate; R: Right hemipelvis; STD: Standard deviation.
