Abstract

L'invention concerne des revêtements cotyloïdiens monopolaires qui enveloppent une tête fémorale pour former une prothèse de hanche. Le revêtement comporte un bord définissant un orifice, cet orifice présentant un diamètre inférieur à celui de la tête fémorale, et le revêtement enveloppant un volume supérieur à 50 pour cent de la tête. Un anneau de contrainte peut être utilisé conjointement avec le revêtement cotyloïdien monopolaire contraint pour rendre la tête fémorale plus solidaire du revêtement cotyloïdien et éviter une dislocation. L'invention concerne aussi des ensembles, des prothèses totales et des procédés de mise en place de prothèse ; des revêtements et des anneaux de contrainte exempts de cavité ou comportant une ou plusieurs cavités ; le procédé selon la revendication 114, dans lequel le revêtement comporte au moins deux cavités.
