When fitting crutches, how much space should be allowed between the crutch and armpit?

When fitting crutches, it is essential to maintain the right amount of space between the crutch and the user's armpit to ensure safety and comfort during use. Allowing 2-3 fingers of space between the crutches and the armpit is the recommended guideline because this distance strikes a balance between providing adequate support and preventing any pressure or discomfort on the axillary area.

Having too little space can lead to unnecessary pressure on the nerves or blood vessels in the armpit, potentially causing pain or numbness in the arms. Conversely, allowing too much space may compromise stability and support, making it difficult for the user to maintain their balance while walking with the crutches. This specific spacing ensures effective use of crutches while allowing for proper posture and movement.
