Decellularized and mineralized osteons with the surrounding lamellae and central Harversian canals are visible. C Electron microscopic image of the AMSA. Decellularized Harversian canals with surrounding bone lamellae are visible. D Animation of the AMSA after subtraction of bone tissue. The Harversian canal system is visible all along the suture anchor
