Question 10

Thumb CMC Abduction Goniometer Alignment

Answer 10

1. Center fulcrum of the goniometer over the lateral aspect of the scaphoid or radial styloid process, so that the proximal and distal arms of the goniometer can be properly positioned over the long axes of the first and second metacarpals.
2. Align proximal arm with the lateral midline of the second (index) metacarpal, using the center of the second MCP joint for reference.
3. Align distal arm with the dorsal midline of the first (thumb) metacarpal, using the center of the first MCP joint for reference.
