Review Question - QID 3233

QID 3233 (Type "3233" in App Search)
A 34-year-old male is an inpatient at a rehabilitation hospital after sustaining severe lower extremity injuries in a motor vehicle collision. As a result, his energy expenditure while ambulating is 40% above baseline after being fitted with an appropriate prosthetic prescription. What is this patient's most likely lower extremity amputation level?

Bilateral transtibial amputee patients have an energy expenditure that is 40% above baseline levels.

The comparative study by Huang et al measured energy consumption by indirect calorimetry and found that mean oxygen consumption was 9% higher for a unilateral transtibial amputee, 49% higher for a unilateral transfemoral amputee (Miller's Review states 65%), and 280% higher for a bilateral transfemoral amputee.

The study by Traugh et al measured oxygen consumption in 9 transfemoral amputees. They found that crutch walking and prosthetic ambulation require the same amount of energy expenditure. Miller's Review also states that a long transtibial amputation expends only 10% above baseline compared to an average length transtibial amputation which expends energy 25% above baseline.
