Elbow is one of the most stable joints of the body. Medial instability of the elbow is more frequent than lateral instability. The term posterolateral rotatory instability of the elbow may be used, if its special test, described by O’Driscoll, is positive. Anatomical reason for this instability is injury of the radial and ulnar branches of the lateral collateral ligament. Cubitus varus deformity is a predisposing condition for this instability. We hereby report, a patient, which was treated surgically because of posterolateral rotatory instability of the elbow associated with cubitus varus.


Vücudun en stabil eklemlerinden biri olan dirseğin instabiliteleri genellikle medial yöndedir. Posterolateral rotatuar instabilite yeni tarif edilen bir kavramdır ve özel bir test ile tanı konulur, instabiliitenin sebebi lateral kollateral ligamanın radial ve ulnar dallarının yaralanmasıdır. Kubitus varus deformitesi, posterolateral rotatuar instabiliteye predispozan bir durumdur. Biz burada cerrahi olarak tedavi ettiğimiz kubitus varus ile birlikte posterolateral rotatuar dirsek instabiltesi olgusunu sunmak istiyoruz.
