This patient underwent 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. A prosthesis was attached to the circular external fixator allowing the patient to bear weight and walk during the treatment.
The patient is a 27-year-old male who developed compartment syndrome after trauma 2 years earlier. This led to a BKA done at an outside medical center. The length of the tibial remnant was 7 cm. Although he was able to wear a prosthesis, he had difficulties related to the short residual limb.
Figures 7A and 7B: AP and lateral x-rays 2 years after surgery. Note the well healed bone 15 cm in length without deformity. Flap coverage was performed by plastic surgeon to improve soft-tissue coverage of the residual limb.
Figures 8A and 8B: Clinical photos showing appearance and length of the residual limb. Prosthetic wear was improved with the lengthened residual leg.
