Abstract: The present disclosure provides medical instruments and medical instrument components having targeted torsional failure. Such targeted torsional failure helps prevent a surgeon from applying excessive torque that may damage an implant or bone, and also helps avoid the problems and complications that arise when medical instruments break within patients during surgical procedures. To provide such targeted torsional failure, the disclosed medical instrument components include a breakaway section designed so that the component breaks at a desired amount of torque, at a desired location, and in a desired way. The provided medical instrument components may also include a sleeve to increase side-loading strength that may otherwise be reduced due to the breakaway section. The increased side-loading strength may help prevent accidental bending-type failures. The presently disclosed medical instrument component therefore provides targeted torsional failure without sacrificing side-loading strength.
