Education on the proper use of crutches can help prevent which type of injury?

1. Wrist fracture

2. Radial nerve entrapment injury

3. Rotator cuff injury

4. Ankle sprain

The correct answer is: Radial nerve entrapment injury

Using crutches properly is essential to prevent injuries related to their use, particularly injuries to the nerves and joints. The risk of radial nerve entrapment injury, which can occur when crutches are not utilized correctly, highlights the importance of educational intervention. When crutches are used, proper positioning is crucial. If the crutches are placed too high or the patient leans excessively on the crutches, it can lead to compression of the radial nerve, which runs down the arm and can be affected by poor posture or incorrect crutch height. This nerve entrapment often results in pain, weakness, or numbness in the wrist and hand, also referred to as "wrist drop." Understanding how to correctly use crutches helps individuals maintain proper alignment and avoid undue pressure on sensitive areas, particularly around the shoulder and upper arm where the radial nerve is located. Thus, proper education on crutch use is vital to minimize the risk of such injuries.
