Which type of graft has the highest rate of cell survival following transplantation?

• A. Fresh frozen cortical graft
• B. Milled cancellous graft
• C. Unmilled cancellous graft
• D. Decellularized graft

Answer: (C)

The highest rate of cell survival following transplantation is typically associated with unmilled cancellous grafts. This type of graft maintains a three-dimensional architecture that is crucial for the survival of viable cells post-transplantation. The configuration of unmilled cancellous bone preserves the marrow spaces, allowing for better nutritional and vascular support, which contributes significantly to cell viability. Additionally, unmilled cancellous grafts often contain a higher number of viable osteocytes and progenitor cells compared to milled grafts, which can lead to improved integration and healing at the recipient site. The structural integrity that unmilled grafts offer enhances the ability of the graft to support cellular activity and regeneration, promoting a favorable environment for bone healing. In contrast, other types of grafts, such as milled cancellous or decellularized grafts, may experience reduced cell survival due to the alteration of their natural structure and loss of critical cellular components that aid in integration and vitality. Fresh frozen cortical grafts, while beneficial in some contexts, can also have lower rates of cell survival compared to unmilled cancellous grafts due to issues such as dehydration and loss of cellular integrity during the freezing process. These factors all contribute to why unmilled cancellous grafts are recognized for their
