To prevent hip contractures after leg amputation, which position is recommended?

• A. Prone with hip extension for 30 mins 3-4 times/day
• B. Supine with limb elevated on pillow
• C. Sitting in a chair with leg extended
• D. Lying on back with hips flexed

Answer: (A)

Preventing hip flexion contractures after a leg amputation hinges on keeping the hip in an extended position so the hip flexors can lengthen and maintain range of motion. Placing the patient prone with the hip extended periodically—about 30 minutes, several times a day—stretches the hip flexors (like the iliopsoas) and counteracts shortening from immobility. This position also helps maintain proper residual limb alignment for future prosthesis use.

Elevating the remaining limb while lying on the back promotes hip flexion and can lead to a contracture. Sitting with the leg extended keeps the hip in a flexed position, which again encourages contracture development. Lying on the back with the hips flexed same way keeps the hip in flexion. While elevation can be useful briefly after surgery for edema, it should not be prolonged as the primary strategy for contracture prevention.
