Abstract
1. Contact study of the human hip joint was performed in order to understand load-deformation pattern under compressive loading, contact area and contact pressure by our method. 2. Weight-bearing function of the hip joint was confirmed. Deformation of articular cartilage and subchondral bone were made reasonably and joint congruity was considered to be obtained with increasing load. 3. Neither contact area nor distribution of the contact pressure were symmetrical or concentric, and both were dependent on the magnitude of load. 4. The relationship between weight-bearing and early cartilage degeneration was discussed. 1. Belastungsuntersuchungen des menschlichen Hüftgelenkes wurden durchgeführt, um einen Einblick zu gewinnen in die Belastungsverformung des Gelenkes unter Druckbelastung, sowie um eine Information zu erhalten über die Belastungsflächen und deren Druckbeanspruchung. 2. Die lasttragende Funktion des Hüftgelenkes wurde bestimmt. Die Belastungsdeformation des Gelenkknorpels und des subchondralen Knochens wurde dargestellt und es wurde festgestellt, daß mit zunehmender Belastung eine Verbesserung der Gelenkkongruenz erreicht wird. 3. Weder die Kontaktfläche noch die Druckverteilung waren symmetrisch oder konzentrisch, und beide waren abhängig von der Größe der Belastung. 4. Die Wechselbeziehungen zwischen Belastung und vorzeitiger Knorpeldegeneration werden diskutiert.Keywords
