Bidirectional Limb Salvage and Its Impact on Residual Limb Survivorship: Is a Partial Calcanectomy in Ambulatory Midfoot Amputees Worthwhile?

Partial calcanectomies and midfoot amputation are commonly used functional limb salvaging interventions; however, it is well documented that they independently result in global biomechanical disruption of diabetic foot, further placing the residual limb at risk for limb loss. We retrospectively identified and reviewed 9 ambulatory midfoot amputees (10 feet) who developed heel osteomyelitis, whom were treated with an ipsilateral partial calcanectomy to determine whether the combined anterior and posterior interventions result in additive dysfunction that impacts function or places the residual pedal construct at risk for limb loss.
