The top of the crutch should be maintained at which level for comfortable crutch walking?

Appeared in: AIIMS Rishikesh NO - 2019

Explanation

The correct placement for the top of a crutch is 2-3 finger widths (about 5 cm or 1.5-2 inches) below the axilla.
This gap is essential to prevent pressure on the nerves and blood vessels in the armpit, which can lead to a serious condition called crutch palsy.
Proper fitting ensures that the patient's body weight is supported by their hands and arms on the handgrips, not by their axillae.
The handgrips should be positioned to allow for a 15-30 degree bend at the elbow, which provides optimal leverage and support.

Option A: Placing the crutch top directly at the level of the axilla causes compression of the brachial plexus nerves and axillary blood vessels.
Option C: A distance of 10-12 inches below the axilla is too large. The crutches would be too short to provide any meaningful support, making them ineffective and unsafe.
Option D: The pelvis is not the correct anatomical landmark for determining the height of axillary crutches. Measurements are taken from the axilla and by ensuring proper elbow flexion.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Correct Crutch Fitting and Measurement as background academic context rather than a clinical decision trigger.
A nurse's primary role includes ensuring patient safety, which involves correct fitting of assistive devices like crutches and educating the patient on their proper use.
Improperly fitted crutches can lead to nerve damage (crutch palsy), poor posture, instability, and an increased risk of falls.
Patient education should cover not leaning on the axillary pads, bearing weight on the hands, checking crutch tips for wear, and navigating stairs and chairs safely.

How to Approach the Question

First, identify the core question, which is about the correct placement of crutches.
Recall the standard guidelines for fitting assistive devices, specifically axillary crutches.
Focus on the key safety principle: avoiding pressure on the axillary nerves and blood vessels.
Evaluate each option against this principle. The correct distance must create a safe gap.
Option A (at the level) creates direct pressure. Option C (10-12 inches) is too far. Option D (pelvis) is an incorrect landmark. Option B (2-3 fingers below) provides the necessary safe gap.
Select the option that aligns with the established clinical standard for crutch fitting.
