Which statement is true about fitting Lofstrand forearm crutches?

• A. Forearm cuff should be 4-5 inches below olecranon
• B. Forearm cuff should be 1-1.5 inches below olecranon
• C. The handgrip should be at shoulder level
• D. Forearm cuff should be above the elbow

Answer: (B)

Setting up Lofstrand forearm crutches correctly hinges on where the forearm cuff sits relative to the elbow. The cuff should cradle the forearm and allow the elbow to stay slightly flexed while the weight is borne through the forearm, not the hand or shoulder. Positioning the cuff about 1 to 1.5 inches below the olecranon provides a stable, comfortable base: the elbow can bend naturally and the cuff remains in secure contact with the forearm. If the cuff is placed higher, near or above the elbow, it can press on soft tissue and the joint, causing pain and restricting movement. If it’s placed too far below, the forearm lacks solid contact, which reduces control and makes weight transfer inefficient, increasing strain on the wrist or shoulder. The handgrip should be at a height that allows the elbow to be slightly flexed and the wrist to be in a relaxed position, not at shoulder level. This positioning optimizes stability and safe weight bearing, making the 1 to 1.5 inches below the olecranon the best fit.
