However little has been reported in patients who receive tibiotalocalcaneal arthrodesis with femoral head allografts for a rigid cavovarus foot type. It has been freeze dried sterilized with gamma irradiation and has an approximate weight of 20g. Sterigraft Femoral Head Bone Bank The donor femoral head allograft is secured in the Arthrex Allograft OATS Workstation and perpendicular alignment is confirmed with the OATS sizer. . Autografting with the removed femoral head has been used for several decades to achieve better coverage but the long-term benefits of this technique remain controversial with some series reporting high rates of graft resorption and collapse. Natural bone matrix facilitates cell attachment and proliferation and vascular in-growth. A tight fit is achieved by fine adjustments to the graft with a saw and this is used as a stem to place the graft into the site of the iliac osteotomy. A recent study by And
