When fitting crutches, the elbow should be flexed approximately how many degrees?

• A. 0 Degrees
• B. 60 Degrees
• C. 90 Degrees
• D. 30 Degrees

Answer: (D)

Having the elbow slightly bent when fitting crutches sets up the hand through which most weight is borne and keeps the shoulder relaxed. About 30 degrees of elbow flexion provides a comfortable, neutral wrist position and stable leverage, so you can advance the crutch without lifting with the shoulder or pressing into the armpit. If the elbow is straight, weight tends to shift toward the axilla and the shoulder bears more strain, making the stance unstable and uncomfortable. If the elbow were very flexed (like 60 or 90 degrees), the lever becomes awkward to use, increasing effort and fatigue and reducing control during gait. Thirty degrees strikes the right balance for a safe, efficient, and comfortable fit.
