Partial Calcaneus Reconstruction using 'Opportunistic Grafts': A Case Report.

Although replantation of an amputated extremity has been successfully performed, occasionally the surgeon is forced to amputate in the case of an unsalvageable open fracture. These appendages can theoretically act as an autologous 'bone and tissue bank' for patients if they have reconstructable contralateral injuries. We present a case of an athlete who sustained a Gustilo and Anderson IIIC injury on 1 leg resulting in a below knee amputation. Her other lower leg had a traumatic amputation of the heel pad, partial amputation of the calcaneus, and complete Achilles tendon loss. Tissues from this amputated appendage were utilised to restore the anatomy of the contralateral extremity. The distal tibia and the tibialis anterior from the amputated limb were used to reconstruct the missing posterior tuberosity of the calcaneus and the Achilles tendon respectively. The soft tissue deficiency of the heel pad was restored with an anterolateral thigh free flap. At 2-year follow-up, the patient is pain free and back to playing soccer. This case highlights the opportunistic use of amputated parts to reconstruct a calcaneus and Achilles tendon. A multidisciplinary approach with plastic surgeons is required. The main advantage of this 'Spare Part Surgery' philosophy is to provide autologous graft of a similar geometry and to avoid harvesting tissues from an additional donor site.
