  • Patent number: 6162226
    Abstract: The present invention provides an orthopaedic instrument system and method for reaming a long bone to a predetermined depth. The instrument system includes an elongate reamer having a proximal portion and a bone contacting surface with an integral cutting element. A stop indicating sleeve having an axial bore and a stop indicating element is removably disposed about the reamer. The stop indicating sleeve may be provided with a stop element and a distal bone contacting surface. Reaming beyond the predetermined reaming depth forces the stop indicating sleeve proximally and urges the stop element on the sleeve into engagement with a stop engaging element provided on the reamer.

  • Patent number: 5989259
    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.
