German term or phrase: Y-Fuge
Taken from a medical report about a patient who had surgery due to a dislocated hip.

Der dorsale Pfeiler ist intakt und das zentrale acetabuläre Fragment ist aus der Y-Fuge herausgebrochen.

English translation:triradiate cartilage (in pediatrics) or triradiate suture
Explanation:
All three bones of the pelvis (the ilium, ischium, and pubis) together form the acetabulum. The three bones are initially separated by a Y-shaped triradiate cartilage that begins to fuse after puberty. The fusion is complete between 20 and 25 years of age.
In adult patients it is no longer known as the triradiate cartilage complex but simply as the central acetabulum or perhaps the triradiate suture (since it has become a synostosis).

The description is weird because it says that the posterior column is intact and the central fragment has broken off the triradiate suture. How can it break off a suture which extends to the labrum in 3 regions?. I would simply translate it as "Posterior column intact with the central fragment dislocated from the cup".

agree  Arne Krueger: Sounds good. I assumed the patient is a kid. Good that you gave reference for older patients as well.

1. Definition

Als Y-Fuge bezeichnet man eine Y-förmige Knorpelfuge des Acetabulum.
2. Anatomie

Die Y-Fuge wird von den Anteilen des Os ilium, des Os ischii und des Os pubis gebildet. Diese drei Knochen des Os coxae treffen im Bereich des Acetabulum aufeinander.
3. Klinik

Die drei Hüftbeinanteile (Os ilium, Os ischii und Os pubis) synostosieren zwischen dem 5. und 7. Lebensjahr, innerhalb des Acetabulums jedoch erst im 14.-16. Lebensjahr.

The acetabulum is formed by the three bones of the pelvis (the ischium, ilium and pubis). Between them is a *****Y-shaped cartilaginous growth plate (the triradiate cartilage) ****which is usually fused by age 14-16. The ball and socket articulation allows for a high degree of mobility. The acetabular labrum increases the depth of the joint 1, thereby increasing the stability of the joint but causes a reduction in the movement at the joint. In comparison to the shoulder joint, it permits less range of movement due to the increased depth and contact area but displays far more stability.
