Abstract

To avoid requiring physicians to machine a connecting apparatus in the operating room, and to easily and accurately attach and secure rods and bone screws through the appropriate combination of connectors; a feature made possible by multiple connectors, each of which includes a through-hole through which a rod can be inserted, a short rod having the same diameter as the rod, with the short rod being directed in a direction substantially orthogonal to an axial direction of the through-hole and having a length required f or the short rod to be inserted and screwed into the through-hole, and an internal thread portion that allows an external thread member to be screwed therein, with the external thread member locking the rod or short rod inserted into the through-hole; and in which configuration a first connector can be set on the rod by inserting the rod into the through-hole therein, the short rod of a second connector can be arranged in a rod-attaching portion of a bone screw, and the short rod of the first connector can be inserted into the through-hole in the second connector.
