Non-Systems NPTE Practice Exam

Avoiding pressure in the armpit is key because the brachial plexus runs near that area and can be irritated or compressed when weight is borne through the axilla. Forearm crutches (Loftstrand) have a cuff around the proximal forearm and rely on the hands and forearms to bear most of the load, keeping the armpit free from weight. This design minimizes pressure on the brachial plexus compared with axillary crutches, which press into the armpit and can compress nerves and vessels. A cane or a walker transfers weight through the hands and arms rather than the axilla, so they don’t press on the brachial plexus in the same way. Therefore, the forearm crutch is the device that avoids transmitting pressure to the brachial plexus area.
