Lower Extremity Amputations in At-Risk Patients: A Focus on Tissue Viability and Function in the Compromised Limb.

Amputations distal to the ankle joint are commonly performed in efforts to preserve a limb. Thorough examination of lower extremity biomechanics, patient functional status, and patient goals must be used to help prevent reulceration and further amputation. Once infection is resolved in the acute setting, musculotendon balancing should be considered at the time of amputation closure to maintain functionality of the limb. Patients should be closely followed postoperatively and monitored for biomechanical deformity that needs to be addressed. Careful attention to detail and adherence to surgical principles can help keep patients active and prevent further amputation.
