Ultrasound imaging of residual limbs: new use for an old technique

The use of ultrasound for diagnosing problems in the residual limb of an individual with an amputation has not been documented in the literature. We present a case where this modality was particularly useful in the diagnosis of an extensive abscess in the distal stump. Ultrasound imaging of compromised residual limbs is useful in the diagnosis of stump infections with infected muscle tissue and deep fluid collection. This technique can help shorten the course of intravenous antibiotics by clarifying the need for surgical intervention.
