Also known as axillary crutches, **Underarm Crutches** are a traditional and widely used mobility aid that provides support by placing weight through the user's underarms and hands. They consist of a vertical support shaft with a padded top that fits under the armpit, a handgrip, and often an adjustable height mechanism. These crutches are typically prescribed for individuals with **lower limb injuries** like ankle sprains, fractures, or during post-surgical recovery, when full weight-bearing on one or both legs is not possible or advisable. While effective for offloading weight, proper fitting is crucial to prevent nerve damage in the armpit. Users rely on their upper body strength to maneuver and bear weight through their arms. Underarm crutches are a temporary but essential tool for individuals needing to maintain mobility while allowing injured lower limbs to heal, providing the necessary stability and support for ambulation.
