Patent ID: 7828851

Claim:
A prosthetic trial for a joint prosthesis, comprising: a body including a channel having a catch; and a stem including at least one resilient member configured to be: inserted into said channel in a first direction until said at least one resilient member passes by said catch; and latched onto said catch to prevent said resilient member from passing by said catch in a second direction substantially opposite to said first direction, wherein said stem includes a movement-limiting element configured to engage said body and thereby limit movement of said resilient member in said first direction through said channel, wherein said channel includes a distal opening having a first width at a distal end of said body, said stem including: (i) a proximal section configured to be inserted into said channel; and (ii) a distal section configured for implantation in a bone, wherein said movement-limiting element comprising a proximal end of said distal section of said stem, said proximal end of said distal section of said stem having a second width greater than said first width of said distal opening of said channel, said proximal end of said distal section of said stem being configured to engage said distal end of said body.
