Sizing for the proximal phalanx prosthetic requires 4 measurements:

1. Finger D: 1-5 left or right hand.
2. Original finger length in millimeters (Our G prosthetic is best balanced at 80% of original finger length.  Compare finger length to other hand if possible for this measurement)
3. Proximal phalanx length (measure from palm side finger crease to tip of stub in mm)
4. Ring size (slide on a ring sizer that fits comfortably and not too tight. The ring sizer should be able to slide all the way up to the base of the finger.)
