Translation - English-German - Lumbar Spine Joint Indicator

Lumbar spine => Lendenwirbelsäule
Joint => Gelenk
Indicator => Anzeiger/Indikator

but if you see it in reality, it's a dictionary-request, isn't it, Francky?

Hallo,

Das Problem ist, das wir nicht alle Sprachen in unseren Wörterbücher finden!

Da diese Texte bei uns für Produktettiketierung und Katalogue verwendet werden, ist es sehr wichtig die Korrekte Bezeichnung zu haben!

Hello Franz und leticiaschlup, as here there isn't only one single word, but an association of several words, even if it is about only one item (device), according to what leticiaschlup said about difficulty to find out meaning of these words , I think we can accept this translation request. What do you think, Franz?

ok :-)

but still I don't really understand the second part "joint" has 30 different meanings in german. I don't know, which one to translate for.
Exists maybe an image/picture to see it?
Or some other helps?

Also "joint"-"Gelenk" scheint mir nach dem Bild richtig zu sein. Komisch kommt mir eher der "Indikator" vor. Treffer bei Google für
- Gelenkindikator: 0 (!)
- Gelenkanzeige: 1
- Gelenkmesser: 25
- Gelenkmessgerät: 54
Könnte es das sein?

Could a joint indicator be something like that? (There are 2 pictures at the bottom)
