The surgical marker (10) according to the invention is characterised in that it is formed, on the one hand, by a hollow screw (11) which is intended to be implanted in a bone and whose inner bore is blind, and, on the other hand, by a pin (14) which is intended to be engaged in this hollow screw (11). In addition to such a surgical marker (10), the measuring device (25) according to the invention comprises a flag marker (26) which for its part is formed, on the one hand, by a support pin (27), which is likewise to be implanted in a bone, and, on the other hand, at right angles to this support pin (27), by a graduated rule (28), the assembly advantageously constituting a U-shaped frame suitable for checking orientation and distance. Application, in particular, to the positioning of a hip prosthesis. Le repère chirurgical (10) suivant l'invention est caractérisé en ce qu'il est formé, d'une part, d'une vis creuse (11), qui est destinée à être implantée dans un os, et dont l'alésage interne est borgne, et, d'autre part, d'une broche (14), qui est destinée à être engagée dans cette vis creuse (11). Outre un tel repère chirurgical (10), le mesureur (25) suivant l'invention comporte un repère en drapeau (26) formé, lui-même, d'une part, d'une broche de support (27), à implanter, elle aussi, dans un os, et, d'autre part, d'équerre avec cette broche de support (27), d'une réglette graduée (28), l'ensemble constituant avantageusement un cadre en U propre à un contrôle d'orientation et de distance. Application, notamment, à la pose d'une prothèse de hanche.
