Abstract:
The authors report on a case of a complete protrusion of the cup of the hip joint into pelvis. Angiographic examination documents a considerable displacement of iliac vessels caused by the pressure of the displaced acetabular cup which poses a great risk of the injury of vessels during the revision surgery. As a solution of this complication the authors used a separate extraperitoneal approach described in literature as an approach to iliac vessels after Leitz allowing a safe removal of the acetabular cup and the ball of the prosthesis. For the removal of the stem the transgluteal approach was used. Key words: Pelvic protrusion of the acetabular cup, angiography, extraperitoneal release of iliac vessels.
