Tail abnormalities
Also known as: Knickrute · Kink tail · Screw tail · Rutenknick · Congenital tail deformity · …
Overview
What it is
Tail abnormalities (Rutenanomalien) are congenital malformations affecting the skeletal system, specifically the tail bones (caudal vertebrae). They occur during embryonic development in the womb when the individual vertebrae do not form properly, leading to fused, misshapen, or shortened bones. This is a structural issue of the spine's tail section and is typically inherited in a complex manner.
How it presents
Owners will usually notice a visible or palpable kink, bend, or unusual shortness in the puppy's tail right from birth. In the vast majority of cases, these abnormalities do not cause any pain or affect the dog's daily life.
Treatment
Treatment is generally unnecessary as this is primarily a cosmetic issue. If complications like chronic irritation or pain develop, a one-time surgical tail amputation may be required, costing between 0 and 1000 EUR.
How it's tested
Röntgenologische Untersuchung der Wirbelsäule und Rute(Röntgen Wirbelsäule/Rute)
Primary testRadiographDie Diagnose erfolgt durch eine klinische Untersuchung und wird mittels Röntgenaufnahmen abgesichert, um das Ausmaß der Deformationen der Schwanz- und Rückenwirbel (z. B. Keilwirbel) zu beurteilen.
Issuing body: vet
Result scheme: OFA-Hip
Röntgenuntersuchung der Rutenwirbel(Röntgen-Rute)
Primary testRadiographDurch eine Röntgenaufnahme der Rute können Fehlbildungen, Blockwirbel oder Knicke der Rutenwirbel exakt dargestellt und von traumatischen Veränderungen abgegrenzt werden.

Röntgenuntersuchung der Rute(Röntgen Rute)
Primary testRadiographEine Röntgenuntersuchung der Rutenwirbel dient dem sicheren Nachweis von Wirbelfehlbildungen wie Keilwirbeln, Blockwirbeln oder Knickruten, die klinisch nicht immer eindeutig tastbar sind.
