A system for attaching a piece of osteosynthesis equipment against a bone tissue includes at least a screw, and a screwdriver having a handle extended by a rod with an adapater to engage the screw. A portion of the guide member of the screwdriver protrudes in front of the end-piece of the screwdriver and extends along or around a portion of the screw to guide the screw in axial translation. The guide member has a front end forming an abutment of the screwdriver against the surface of the piece of osteosynthesis equipment on completion of a predefined depth of screwing of the screw into the bone tissue. The guide member can be set at a chosen length of extension, corresponding to a predefined depth of insertion of the screw. After insertion, the screw can be severed, and optionally fused with the piece of equipment to reinforce the locking of same. |
