Digit 1 Length is taken from the distal tip of the thumb to the palmar digit 1 crease. Digit 2 link length is the distance from the distal tip of the index finger to the MCP Joint, measured using the proximal transverse palmar crease. Digit 2 distance from D2 MCP joint to DIP joint is the distance from the D2 DIP Joint to the proximal transverse palmar crease. Maximum grip diameter is taken by having the subject touch the distal tips of the first and third digits together and slide them over a cone until the two digits can no longer touch. Hand Circumference is taken around the widest part of the palm, typically around the breadth of the knuckles.

The top arrow on the schematic stapler diagram represents the proximal trigger distance and the bottom arrow represents the distal trigger distance while the devices were in “fire-mode”.

Over 48 male and 8 female general surgeons had their preferred glove size recorded. The sizes were normally distributed among men and women. The numbers over the bar indicate amount of men and women at that particular size (P < 0.001).

The curves are the normal distribution of male and female surgeon's distance from D2 MCP to DIP Joint. The Stapler 1 reference line (leftmost vertical dashed line) is the proximal grip distance on the stapler 1 (5.13 cm). The Stapler 2 reference line (rightmost vertical dashed line) is the proximal grip distance on the stapler 2 (6.83 cm). These locations are typically where the index finger would be located during firing of the surgical stapler.
