What is a significant advantage of using Lofstrand crutches over axillary crutches?

1. Lofstrand crutches are more durable.

2. Lofstrand crutches are more aesthetically pleasing for the patient.

3. There is a decreased risk of brachial plexus injury when using Lofstrand crutches.

4. Lofstrand crutches provide better stability for patients.

The correct answer is: There is a decreased risk of brachial plexus injury when using Lofstrand crutches.

Lofstrand crutches, also known as forearm crutches, offer a significant advantage regarding the risk of brachial plexus injury. This risk is primarily associated with the improper use or prolonged pressure from axillary crutches, which rest against the axilla and may compress the brachial plexus nerves. This can lead to nerve injury or discomfort, particularly in patients who rely heavily on crutches for prolonged periods. In contrast, Lofstrand crutches do not bear weight directly under the arms; instead, they provide support through the forearm. By using cuffs that encircle the forearms, these crutches allow for a more natural arm position and improved control during ambulation, reducing the risk of nerve compression and associated injuries. This design is especially beneficial for long-term use, as it minimizes potential complications related to the brachial plexus. While durability, aesthetics, and stability are important factors to consider when selecting assistive devices, the decreased risk of brachial plexus injury stands out as a critical advantage of Lofstrand crutches, particularly in clinical populations where safety and prevention of secondary complications are priorities.
