Tripod sign.
"Tripod Sign" or "Amoss's Sign" is a sign of meningeal irritation. Although useful in diagnosing meningitis, it is not pathognomic and may be seen in a variety of clinical conditions. Infants < 1 year of age and immunocompromised individuals may not demonstrate signs of meningeal irritation. Since elicitation of the sign requires voluntary sitting up, it is of limited use in patients with marked altered sensorium and young infants.
