Abstract
A prosthetic stem inserter device includes an elongate rod member having a handle portion and an elongate rod member having a distal portion which has a plurality of surface features formed thereon which define a series of predetermined stem insertion depths. The device further includes a depth guide member having a proximal portion removably and replaceably engageable with the surface features on the elongate rod member. A distal, bone engaging portion of the depth guide member protrudes beyond a distal end of the elongate rod member. The depth guide member includes a mounting plate having a substantially hemispherical opening slot therein and a pair of distally extending prong elements. Each prong element has a first, longitudinally extending portion and a second portion that is angled with respect to the first portion. The second portion is adapted for contacting a plane of calcar bone in a prepared femoral cavity when a femoral stem is inserted into the cavity.
