Beschreibung
Zusammenfassung:	A reverse hip prosthesis include an acetabular cup arrangement configured for insertion into an acetabulum of a patient and fixation therein, an acetabular ball configured for threaded attachment to the acetabular cup arrangement, a femoral stem configured for insertion into an intramedullary femoral canal of the patient, and a femoral cup arrangement configured for attachment to the femoral stem and to operatively receive the acetabular ball therein. The acetabular cup arrangement includes an anchor portion which becomes fixed to the patient's acetabulum and is the largest size suitable for the patient, and an insert which comes in different sizes and are connectable to the anchor portion, so that the most appropriate insert for the patient may be used. The acetabular cup arrangement and ball are interconnected with a threaded stem that also functions as an artificial Ligamentum Teres.
