orearm
These are the most common type in Europe, used in the US almost exclusively by people with permanent [disabilities], though orthopaedic surgeons are now beginning to perscrib forearm crutches for patients with shorter term needs. Forearm crutches are used by slipping the arm into a cuff and holding the grip. The cuff is typically made of either plastic or metal and features a V-type opening in the front allowing the forearm to slip out in case of a fall. Forearm crutches are also sometimes referred to as Lofstrands (for their inventor, A. R. Lofstrand, Jr., who patented them in 1945),[1] Canadian crutches (since they are commonly used in Canada), elbow crutches or even Walk Easies (Walk Easy is a brand name).
Underarm
These are the most common type in the United States, and are used most often by people with temporary disability or injury. These are used by placing the pads under the armpits and holding the grip, which is below and parallel to the armpit pad. These are sometimes known as axillary crutches.
Strutters
These are a variation on under-arm crutches, incorporating large soles which remains flat on the floor or ground while the user walks. They allow for an improved walking gait, and distribute body weight to reduct the risk of nerve damage caused by underarm crutches.
Platform
These are less common and used by those with poor hand grip (due to arthritis, cerebral palsy, etc.). The arm rests on a horizontal platform and is strapped in place. The hand rests on a grip which, if properly designed, can be angled appropriately depending on the user's physical handicap.
Knee Support
These crutches are useful for patients whose injury or disability is below the knee. They allow the knee of the injured leg to be placed on a support, whereby the injured leg now points backward behind the patient. This style of crutch affords the patient the ability to have one or both hands free to carry objects. Upper thigh atrophy is also reduced due to the fact that half the patients weight is now supported by each thigh rather than one thigh and the armpits.
