What is the most common site for harvesting an autologous bone graft?

The most common site for harvesting an autologous bone graft is the anterior or posterior iliac crest. This site is preferred due to several factors that enhance its suitability for bone grafting procedures. The iliac crest is accessible with minimal morbidity, allowing for a relatively straightforward surgical approach.

Additionally, the quantity of bone that can be harvested from the iliac crest is significant, providing enough material for various orthopedic and reconstructive procedures. The cortical and cancellous bone found in this area is also advantageous since it supports bone healing and regeneration, which are critical in grafting scenarios.

Although other sites like the femur, radius, and scapula can be used for harvesting bone grafts, they are less favorable due to either the limited amount of bone available or higher associated risks and complications during and after harvesting. The iliac crest stands out as the gold standard in autologous bone graft harvesting.
