A sighting guide (2) is fixed on the support at outside the surface, with a sighting axis (X2) aligned on a diameter of the sphere. An abutment arm (4) on an inner part (73A) of femoral neck (73) is connected to the support and includes a distal end (43A) that bears against the inner part when the support covers the femoral head with a sighting axis (X2) aligned on a central axis (X73) of the femoral neck or slightly outwardly offset. Cet ancillaire (1) pour resurfaçage de la tête fémorale comprend un guide de visée (2) définissant un axe de visée (X2). Il comprend en outre :- un support (3) apte à coiffer la tête fémorale (71) et définissant une surface d'enveloppe en portion de sphère, le guide de visée (2) étant fixé sur le support avec l'axe de visée (X2) aligné sur un diamètre de la sphère ; et- au moins un bras (4) de butée sur une partie prédéfinie (73A) du col fémoral (73), ce bras (4) étant relié au support (3) et ayant une extrémité distale (43A) qui est en appui contre la partie prédéfinie (73A) lorsque le support coiffe la tête fémorale avec l'axe de visée (X2) aligné sur l'axe central (X73) du col fémoral ou en léger valgus.
