The Reactivation of the Metal-Metal Pairing for the Total Hip Prosthesisshed than the earlier McKee prosthesis and its successors. A newly developed metal-metal prosthesis is described which was implanted 110 times between 1988 and 1992. To date absolutely no problems have arisen with this new metal-metal pairing.

Primary Stability of Cemented and Noncemented Implantsimmediately after implantation. This stability is defined as inversely proportional to the amount of movement. A large relative movement therefore reflects a low primary stability and vice versa. Because this relative motion is between 1 and 1 000 μm, it is also called micromotion. The concept of pr

Gait Analysis: A Biomechanical Tool in the Development of Artificial Joints this interplay is altered, especially in joints of the lower extremity. This interplay can be changed by arthritic joint disease (Messier et al. 1992; Harrington 1983), trauma, or corrective surgery, including osteotomies (Prodromos et als. 1985) and joint replacements (Andriacchi et al. 1977).

Gait Analysis of Normal Persons and Patients with Coxarthrosis Before and After Conservative TherapyWell known are the prehistoric cliff paintings in France and South Africa which display the elements of movement in an outstanding manner. It is, however, only in the past three centuries that scientists and researchers have paid special attention to upright walking and the sequence of movements inv

The Cemented Hip Cup: The Weber Polyethylene-Ceramic and Metasul Cups and the High-Pressure Cementinmediate loosening, occurring as a consequence of faulty cementing technique, or immediate stability, as a result of good cementing technique. The subsequent fate of the prosthesis after immediate stability depends on possible factors of interference: (a) premature loosening resulting from infection,

Noncemented Acetabular Fixation in Primary Total Hip Replacement1] and is demonstrated by the survivorship analyses of Sutherland et al. , Morscher and Schmassmann , and others (Fig. 1). Mulroy and Harris found a 20-fold increase in the rate of acetabular loosening between 5 and 11 years.

The Saint Nabor Cup: 8 Years of Experience . It has been shown by Sutherland and Morscher and Schmassmamm that femoral loosening increases linearly with time, whereas socket loosening increases exponentially. A rapid acceleration of socket loosening occurs 7 years post operatively. Orthopedic surgeons therefore rapidly became
