What is a fitting rule for axillary crutches?

• A. Forearm cuff should be 1-1.5 inches below olecranon
• B. Have patient hold crutches 2-3 inches lateral and 4-6 inches anterior
• C. Should be 2-3 fingers below axilla
• D. Crutches should be placed with the armpit under the top of the shoulder

Answer: (B)

A secure, stable gait with axillary crutches depends on placing them so they form a solid base of support while keeping the axillary area free from pressure. The best fitting rule is to position the crutches so the tips are about four to six inches in front of the toes and about two to three inches to the side of the feet. This arrangement creates a stable tripod with each step, allowing the patient to advance the crutches and the opposite leg smoothly without the crutches getting in the way or tipping inward. This setup also helps minimize the risk of nerve or vessel compression in the axilla by avoiding crowding under the arm. The other options describe measurements or placements that either pertain to different devices (like forearm crutches, which use a cuff on the forearm), or rely on unreliable or unsafe distances (such as a finger-width measurement below the axilla) or direct armpit pressure, which is not how axillary crutches should be fitted.
