FIELD: medicinal equipment, orthopedics.
SUBSTANCE: the suggested articular endoprosthesis contains, at least, one element in the form of a head or a cup designed as rotation body with smooth surface made of abrasion-resistant materials at low friction coefficient, for example, isotropic pyrolytic carbon or ceramics interacting with reciprocal surface of the second articular element. Smooth surface of rotation body is divided into segments immovably connected together through interlayers made of foreign material which form the border for fissures' development.
EFFECT: higher efficiency.
