Treatment of Severe Ankle and Hindfoot Deformity: Technique Using Femoral Head Allograft for Tibiotalocalcaneal Fusion Using a Cup-and-Cone Reamer

Abstract

Limb shortening due to structural bone loss in tibiotalocalcaneal arthrodesis is a concern that can negatively impact the patient's gait and weight-bearing. To aid in preventing the risk of limb shortening, the use of a femoral head allograft and intramedullary nail in tibiotalocalcaneal arthrodesis has been shown to successfully preserve limb length in patients with structural bone deficits. We present our technique using a femoral head allograft with a cup-and-cone reamer for the treatment of severe ankle and hindfoot deformity.

Prebent Steinmann Pin to Remove the Broken Retrograde Intramedullary Nail After Tibiotalocalcaneal Arthrodesis

“… 2 Retrograde intramedullary nail is one implant option used in tibiotalocalcaneal arthrodesis because it provides mechanical strength and compression at the fusion site, while being less invasive to soft tissue. 3 , 4 , 5 , 6 However, some fusion failures result in implant overloading, resulting in implant failure. 1 , 7 The accumulated stress at the level of the subtalar joint will most likely cause implant breakage.…”
