摘要

A tool (100) for aiding in the selection an appropriately sized implant (400) for use in performing joint arthroplasty is provided. The tool (100) cooperates with an anatomical joint (101) or with an image (102) of an anatomical joint (101). The tool (100) includes a body (110) for alignment with a first portion (112) of the anatomical joint (101) and a segment (114). The segment (114) is moveable with respect to the body (110). The segment (114) is aligned with a second portion (116) of the anatomical joint (101). The body (110) and segment (114) are adapted for measuring the relative positions of the first (112) and second (116) portions of the anatomical joint (101) for use in the selection an appropriately sized implant (400).
