A surgical instrument includes a stem to be inserted into the medullary cavity of a proximal femur and a grip part slightly offset from and extending approximately parallel to the direction of the stem. The grip part is releasably connected to the upper end of the stem by mutual coupling parts including a peg protruding obliquely from the upper end of the stem and a bore located in the lower end of the grip part. Releasable means for arresting the peg in the bore are formed by the end of a rod which is guided movably in the longitudinal direction of the grip part and by a recess in the peg for receiving this end. The recess in the peg is a continuous bore and the rod, in its arrested position, extends completely through the bore. The upper end of the rod is connected to a handle located in the middle to upper region of the grip part. The rod or the handle is provided with a catch mechanism for securing the rod in the arrested position.
A surgical instrument comprising a stem configured to be inserted into a medullary cavity of a proximal femur, and a grip part extending generally parallel to said stem and releasably connected to an upper end of said stem by a coupling comprising a peg protruding obliquely from the upper end of the stem, a bore located in the grip part for receiving the peg, and releasable means for arresting the peg in the bore, wherein the releasable arresting means comprises a rod which is guided movably in the longitudinal direction of the grip part through a guide bore and a recess in the peg for receiving an end of said rod, wherein said recess is a continuous bore and the rod, in an arrested position, is supported on both sides of the peg in the guide bore.
