The invention relates to a surgical method for positioning a permanent percutaneous electrical connection device in a receiving bone site of a patient, the patient being a human being or an animal, and the device comprising, on the one hand, a plate-implant integrating at least one fixed electrical connection port and, on the other hand, a percutaneous electrical connection abutment designed to be coupled to the electrical connection port, the method comprising the following successive steps:step of preparing the receiving bone site, during which: the cutaneous plane facing the receiving bone site is incised, thenthe periosteum of the receiving bone site is incised and detached and then reclined to clear the bone structure, thenthe bone structure is hollowed out so as to form a cavity in which the plate-implant is to be impactedstep of impacting the plate-implant into the cavity formed in the receiving bone site, during which: the plate-implant is anchored in the cavity formed in the receiving bone site, thenbone fragments are positioned to cover the plate-implant except in the area of the fixed electrical connection port, thensaid bone fragments are covered with a membrane to keep the bone fragments in position so as to ensure guided bone regeneration, said membrane being affixed to the bone structure on one part and to the plate-implant on another part in order to hold the bone fragments in position.
