Abstract
Abstract A quick release handle apparatus for pulling an intramedullary nail includes a handle body with a sliding pushrod that moves an outer cylindrical member over an inner cylindrical member having locking elements. The locking elements engage an annular groove on a nail puller element that attaches to an intramedullary nail. The outer cylinder overlaps the inner cylinder at the locking balls to define the locking position.
