Traube's space
From Wikipedia, the free encyclopedia
Traube's (semilunar) space is an anatomic region of some clinical importance. It's a crescent-shaped space, encompassed by the lower edge of the left lung, the anterior border of the spleen, the left costal margin and the inferior margin of the left lobe of the liver. Thus, its surface markings are respectively the left sixth rib, the left anterior axillary line, and the left costal margin.
Underneath lies the stomach, which produces a tympanic sound on percussion (medicine). If percussion over Traube's space produces a dull tone, this indicates splenomegaly. Assessing this may be more difficult in obese patients.
The normal human spleen measures about 125 millimeters in length, and splenomegaly is an important clinical sign. There are 2 possibilities to evaluate splenomegaly in the clinical examination: percussion and palpation.
Percussion can be done in Traube's space, as described by his pupil in 1868. Another method was described by Donald O. Castell in 1967 (Castell's sign).
