Estimating the term…
This orthopedic assembly has a connection between the ancillary tool and the stem or raspatory that allows both the raspatory and the femoral stem to be positioned in the intramedullary channel of a femur by means of the same ancillary tool. The connector includes a tapped hole extending from the bottom of a conical recess in the femoral end of the stem, or of the raspatory, and a threaded projection provided on the ancillary tool and designed to be screwed into the tapped hole. The bottom of the conical recess in the raspatory and in the stem has a profiled indentation whose edge includes alternating concave and convex curves and is designed to receive a male indexing part of a corresponding profile arranged on the end of the removable neck.
An orthopedic surgery assembly including an ancillary tool for a hip prosthesis, a femoral raspatory and a femoral stem with a proximal end and a removable neck having a bearing span designed to engage a matching recess formed in the proximal end of the stem, said assembly comprising a tapped hole disposed on the stem and extending from a bottom of the recess on the stem for receiving the removable neck, and a threaded projection being formed on one end of the ancillary tool and being structured to be screwed into the tapped hole, both the raspatory and the femoral stem being structured to be positioned in an intramedullary channel of a femur using the same ancillary tool.
