Abstract
An apparatus and method for measuring a version angle of a restored neck of a femur during a hip replacement procedure. The apparatus includes a broach. The broach has a distal end that is insertable into a medullary canal of the neck of the femur. The broach also has a proximal end that extends along a neck axis of the broach. The apparatus also includes a protractor. The protractor includes a rod which is attachable to the proximal end of the broach to extend away from the neck axis of the broach for measuring the version angle of the restored neck of the femur relative to a vertical direction. The method includes inserting the broach, flexing the knee at approximately ninety degrees, orienting the tibia vertically, attaching the protractor to the proximal end of the broach and using it to measure the version angle.
