Description

The theoretical line drawn from the anterior superior spine of the ilium to tuberosity of the ischium, in the moderately flexed hip.

In cases of dislocation of the hip the tip of the greater trochanter of the femur is above the line.

Normally the greater trochanter of the femur lies below this line. However, in cases of dislocation of the hip, the tip of the greater trochanter of the femur lies above the line.


History of the Roser-Nélaton line
Nélaton’s line (Roser-Nélaton line)

“Die diagnose der Luxation erschien uns inden meisten Fällen dieser Art sehr leicht: bei normaler Lage befinden sich die Spina ilii, der Trochanter und der Tuber ischii nahezu in Einer Linie, ist Luxation da, so steht der Trochanter auffallend höher und weiter nach hinten als die Linie, welche man sich von der Spina zum Tuber gezogen denkt.”

Roser W. Hacker, Erfahrungen und Abhandlungen im Gebiete der Chirurgie. Archiv für physiologische Heilkunde, 1846; 5: 142

The diagnosis of luxation presented itself in most cases quite clearly: in a normal situation, the iliac spine, the trochanter and the ischial tuberosity lie nearly on the same line; if there is a luxation, the trochanter lies noticeably higher and more posterior to the line, which one may imagine traced from the spine to the tuberosity

Si l’on examine à l’état normal les rapports exacts du grand trochanter avec les diverses saillies osseuses que l’on trouve sur le bassin, on reconnaît que , si le fémur est fléchi à angle droit avec une légère adduction, le sommet du grand trochanter répond à une ligne qui partirait de l’épine  iliaque antéro-supérieure pour se rendre à la partie la plus saillante de la tubérosité sciatique, et que cette ligne divise en même temps la cavité cotyloïde en deux parties égales.

If one examines, in its normal state, the exact relations of the greater trochanter to the different bony prominences which are found on the pelvis, one recognizes that, if the femur is flexed at a right angle with a light adduction, the summit of the greater trochanter corresponds to a line traced from the anterior superior iliac spine to the ischial tuberosity, and that this line also divides the acetabulum into two equal parts.
