Beim femoroazetabul\u00e4ren Impingement (FAI) vom Cam-Typ bewirkt eine Asph\u00e4rizit\u00e4t am femoralen Kopf-Hals-\u00dcbergang die Induktion von Scherkr\u00e4ften am Azetabulum. Beim Pincer-Typ kann eine Retroversion der Pfanne und\/oder eine vermehrte \u00dcberdachung vorliegen. Ein wichtiger mechanischer Einflussfaktor, welcher ein Impingement oder auch H\u00fcftinstabilit\u00e4t verst\u00e4rken oder kompensieren kann, ist die Femurtorsion. Meistens treten Torsionsst\u00f6rungen kombiniert mit anderen oss\u00e4ren Deformit\u00e4ten auf. Zu beachten ist, dass ein hoher Prozentsatz der Adoleszenten mit kn\u00f6chernen FAI-Morphologien asymptomatisch bleibt. Die Diagnose des FAIS wird daher klinisch gestellt, die Bildgebung zeigt die zugrundeliegende Morphologie. Prim\u00e4re Bildgebung ist das R\u00f6ntgenbild in 2\u00a0Ebenen zur Beurteilung der H\u00fcftgelenk\u00fcberdachung und der azetabul\u00e4ren Version. Die vollst\u00e4ndige Zirkumferenz des Femurs ist jedoch nur in der Magnetresonanztomographie (MRT) beurteilbar, ebenso L\u00e4sionen des Labrums und Knorpels sowie des Knochenmarks und der umgebenden Weichteile. Das MRT-Protokoll sollte routinem\u00e4\u00dfig eine Bestimmung der Rotation des Femurs beinhalten. Zudem sollten fl\u00fcssigkeitssensitive Sequenzen des Beckens zum groben Ausschluss degenerativer oder entz\u00fcndlicher extraartikul\u00e4rer Ver\u00e4nderungen akquiriert werden.<\/jats:p>","DOI":"10.1007\/s00117-023-01197-6","type":"journal-article","created":{"date-parts":[[2023,9,12]],"date-time":"2023-09-12T15:02:26Z","timestamp":1694530946000},"page":"749-757","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Femoroazetabul\u00e4res Impingement beim Jugendlichen und Adoleszenten","Femoroacetabular impingement in adolescents"],"prefix":"10.1007","volume":"63","author":[{"given":"Iris-M.","family":"Noebauer-Huhmann","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felix R.
