Which statement correctly describes Type 3 pelvic fracture?

Which statement correctly describes Type 3 pelvic fracture?

• A. Fracture of the acetabulum
• B. Individual bone fracture
• C. Double break in pelvic ring
• D. Single break in pelvic ring

Answer: (C)

Pelvic stability hinges on the integrity of the pelvic ring as a whole. Type 3 describes a complete disruption of that ring, meaning two separate breaks that disrupt both the anterior and the posterior elements. In other words, both the front and back portions of the ring are broken, producing rotational and vertical instability. This is why the pattern is considered the most unstable and is typically seen after high‑energy trauma, requiring rapid stabilization and thorough evaluation for associated injuries. The other options don’t capture this full ring disruption: an acetabular fracture or an isolated single fracture affects only a specific part, not the complete ring instability implied by a double break.
