Seventy patients over seventy years who are admitted in our hip fracture department with the indication for hemi joint replacement therapy, due to a Garden 3-4 femoral neck fracture or a fracture Garden 1-2 with over 20-degree posterior tilt are randomized to either hemialloplastik or total joint replacement. The patients are followed for 24 mouths with X-ray Stereo Photogrammetric Analysis (RSA) radiographs and clinical examinations.
