"There are 217 bones in the human body. Among them, there are around 230 joints. One of the most complex of these joints is the joint connecting the pelvis and the femur. There are trace amounts of gases within the joint. I can increase the volume of said gases, causing the bone to shatter into 17 pieces. The pieces would embed themselves in the tissue of the leg and lower torso, impeding function in circulatory, nervous, skeletal, muscular, endocrine, and reproductive systems. The resulting damage would not heal, and it will take doctors another fifty years to fully repair."
