PCT No. PCT/FR97/00257 Sec. 371 Date Aug. 13, 1998 Sec. 102(e) Date Aug. 13, 1998 PCT Filed Feb. 10, 1997 PCT Pub. No. WO97/29698 PCT Pub. Date Aug. 21, 1997An instrument including a cutter (2) mountable on a cutter 32 spindle (1) and shaped in such a way that it also acts as a test cup 33 engageable by a test head of a femoral prosthesis. The cutter (2) may be attached to the pelvis (34) by means of nails (29), and the cutter position is detected by sighting means (32) on the cutter spindle (1). The sighting means (32) are then used to arrange the final cup in the same position as the cutter (2) so that the position of the final cup may be selected in such a way that the risk of joint dislocation is reduced.
