During crutch fitting, the elbow should be bent at approximately how many degrees?

• A. 30 degrees
• B. 60 degrees
• C. 90 degrees
• D. 120 degrees

Answer: (A)

The concept being tested is how much the elbow should bend to optimize crutch use. A light bend in the elbow, about 30 degrees, places the forearm in a strong, comfortable position so the crutch can bear weight efficiently and the shoulder stays in a neutral, safer alignment. This slight flexion helps you control the crutch during gait, absorbs some of the load through the forearm, and keeps the wrists and hands in a natural posture.

If the elbow were almost straight, the weight would load the shoulder more, increasing the risk of fatigue, joint irritation, or awkward mechanics. If the elbow were too bent (near 90 degrees), it would make movement awkward, reduce control, and raise energy expenditure while compromising balance. The ~30-degree angle supports a stable, efficient pattern of using the crutches, allowing smooth progression of the opposite leg with the tips maintaining contact with the floor.
