Honda sign
The "Honda sign" (H-pattern[1]) is a radiologic sign seen in case of sacral insufficiency fracture in bilateral sacral insufficiency fractures on a radioisotope bone scan.[2] It gets its name because the shape observed resembles the logo of the Honda motor company, resembling the alphabet "H".
Description
[edit]This sign is typically associated with bilateral fractures of the superior and inferior pubic rami. In simpler terms, it indicates a specific pattern of pelvic fractures where both the upper and lower parts of the pubic bones are fractured on both sides.[2]
While Honda sign is diagnostic of sacral insufficiency fracture, it is visible in only up to 40% of the cases.[3]
