Lengthening of a Very Short Below Knee Amputation Residual Limb to Enhance Prosthetic Wear

This is a case illustrating an 8 cm lengthening of a dysfunctional very short below-knee amputation (BKA) residual limb that was initially 7 cm in length. The lengthening was greater than 100% and resulted in a BKA residual limb of 15 cm. The external fixation index was 1.5 months/cm. A prosthesis was attached to the circular external fixator allowing the patient to bear weight and walk during the treatment.
