Was heisst Acetabulum?
Das Acetabulum ist die Becken- oder Hüftpfanne.
Warum Hüft TEP?
Wann macht man eine Hüft-TEP? Die häufigste Ursache für einen Hüftgelenkersatz ist der Verschleiß des Hüftgelenks (Koxarthrose). Dabei nutzt sich der Knorpel an Gelenkkopf und Gelenkpfanne ab. Mangelnde Passform und eine erhöhte Reibung führen schließlich zu Schmerzen und Einbußen in der Beweglichkeit.
Was ist OS Ischii?
Das Os ischii oder Sitzbein ist ein Teil des knöchernen Beckens. Es bildet gemeinsam mit dem Darmbein (Os ilium) und dem Schambein (Os pubis) das Hüftbein (Os coxae).
Was befindet sich in der Fossa Acetabuli?
In der Mitte ist das Acetabulum zur Hüftgelenksgrube (Fossa acetabuli) ausgehöhlt. In dieser Grube entspringt ein Band (Ligamentum capitis ossis femoris), das einen dünnen Zweig der Arteria obturatoria, die Arteria capitis femoris, aufnimmt. Diese ist an der arteriellen Versorgung des Oberschenkelknochens beteiligt.
Was ist Zona orbicularis?
Die Zona orbicularis ist eine Bandstruktur des Hüftgelenks, die sich schlingenförmig um den Femurhals (Collum femoris) legt.
What is a normal acetabulum?
The acetabular angle using Hilgenreiner’s line should be less than 28º at birth. The angle should become progressively shallower with age and should measure less than 22º at and beyond 1 year of age. The normal range is 33º to 38º. Angles above 47º are seen in patients with acetabular dysplasia. A measurement between 39º and 46º is indeterminate.
What is the meaning of acetabulum?
Acetabulum. A deep semispherical socket cavity in the lateral surface of the hip, with which the femoral head articulates, located at the convergence of the ilium, ischium , and pubis. The acetabulum is functionally comprised of two columns (anterior and posterior) and two walls (anterior and posterior). Segen’s Medical Dictionary.
What does acetabulum mean?
The acetabulum is a rounded depression in the hip bone. It forms a socket which contains the ball-shaped head of the thigh bone, or femur, allowing it to rotate quite freely. Together, the acetabulum and the head of the femur form what is known as the hip joint.
What is the function of the acetabulum?
It is a synovial ball and socket joint that occurs between head of femur and acetabulum of hip bone. Its primary function is to make the legs mobile without weakening the ability to support the weight of human body in both static and dynamic postures. Hip joints are most important factors in maintaining balance of body.
