A hip prosthesis comprising a first fastening assembly (1, 2, 6, 12, 13) intended for being mounted in the hip bone (A) and a second fastening assembly (4, 5, 7, 14) intended for being mounted in the upper extremity of the femur (F), wherein the first (1, 2, 6, 12, 13) and the second (4, 5, 7, 14) fastening assemblies are interconnected by means of a pivotable connection (8, 108) wherein all parts (1, 2, 4, 5, 6, 7, 8) of the hip prosthesis are so small and/or slender that they can each be arranged in the intended end position thereof via a bore (9) in the femur (F), which bore (9) extends from the outside (Fo) of the femur (F) through the femoral neck (Fn) substantially in the direction of the imaginary longitudinal center line (LFn) of the femoral neck (Fn) to the femoral head (Fh).

Une prothèse de la hanche comprend un premier ensemble de fixation (1, 2, 6, 12, 13) destiné à être monté dans l'os de la hanche (A) et un second ensemble de fixation (4, 5, 7, 14) destiné à être monté dans l'extrémité supérieure du fémur (F), les premier (1, 2, 6, 12, 13) et second (4, 5, 7, 14) ensembles de fixation étant reliés entre eux par un raccord pivotant (8, 108). Toutes les parties (1, 2, 4, 5, 6, 7, 8) de la prothèse de la hanche sont si petites et/ou si minces qu'elles peuvent être placées dans leur position d'extrémité voulue par un orifice (9) pratiqué dans le fémur (F) et s'étendant depuis l'extérieur (F¿o?) du fémur (F) jusqu'à la tête du fémur (F¿h?) en passant par le col du fémur (F¿n?), sensiblement dans le sens de la ligne médiane longitudinale imaginaire (LF¿n?) dudit col (F¿n?).
