What is the recommended distance from the axilla to the top notch on a crutch?

• A. 6 cm (2–3 finger widths)
• B. 12 cm
• C. 2 cm
• D. 8 cm

Answer: (A)

Proper crutch fit centers on placing the top notch at a height that keeps the axillary pad from bearing excessive weight while allowing safe, stable support through the hands. About 6 cm (2–3 finger widths) below the axilla is ideal because it positions the pad to clear the armpit and avoids compressing the axillary nerves and vessels, yet still lets the user bear weight through the hands with the elbow flexed roughly 20–30 degrees. If the notch sits too close to the armpit, pressure can injure the axillary contents; if it’s too far away, control and balance suffer and more weight may be placed on the armpit. This 6 cm distance provides a practical, comfortable balance for typical adult use.
