The Boyd amputation is a surgical technique used to treat osteomyelitis of the foot. This amputation is a technically more difficult procedure to perform than the Syme amputation, but it offers certain advantages. The Boyd amputation provides a more solid stump because it preserves the function of the plantar heel pad. Also, because a portion of the calcaneus is left and fused to the tibia, the weightbearing surface is more solid than in the case of a Syme amputation. The authors recommend a Boyd amputation as an alternative to a Syme or a below-the-knee amputation to treat patients with osteomyelitis of the forefoot and midfoot.
