This ancillary device (2) for the correction of the hallux valgus deformation of a patient, comprises a lever (3) comprising an insertion part (11) is configured to be engaged in the medullary canal of the body (6) of a first metatarsal (5), and a bearing part (8) intended to bear against the head (6) of the first metatarsal (5); and a guide member (17) comprising a contact surface (24) intended to bear against the skin of the foot of the patient, and a guide slot (21) extending along a plane of extension and intended to guide a drilling tool. The guiding member (17) is articulated relative to the lever (3) between a first position in which the contact surface (24) of the guiding member (17) bears against the skin of the foot of the patient when the insertion part (11) is engaged in the medullary canal of the body (6) of the first metatarsal (5), and a second position in which the contact surface (24) of the guiding member (17) is located at a distance from the skin of the foot of the patient when the insertion part is engaged in the medullary canal of the body (6) of the first metatarsal (5).
