肋骨應該是cortical bone autograft

Cancellous bone may be harvested from any long bone metaphysis; 
可以從任何長骨幹骺端獲取鬆質骨；
however, the proximal humerus, proximal tibia, distal femur, and ilial wing are most often used because they are accessible and contain large amounts of cancellous bone. 
然而，最常使用的是肱骨近端、脛骨近端、股骨遠端和髂翼，因為它們易於接近且含有大量鬆質骨。
