The modified Boyd fusion: An uncommon limb salvage procedure

This study reports on four patients who underwent a Modified Boyd Fusion, which consists of a Chopart amputation with a subtalar and ankle joint arthrodesis utilizing an intramedullary nail. This technique affords the patient a rigid platform for ambulation by controlling the rearfoot and provides maximal limb length preservation. This technique also helps prevent the complications associated with a Chopart amputation alone, which consist of an equinovarus deformity and associated increased plantar pressures of the distal stump with high risk of subsequent wound development and failure.
