You for referring mr. samuels to my office. i saw him on march 3, 2017. mr. samuels has a 4-month history of increasing pain in his right distal femur. he first noticed pain after being kicked in the leg at a soccer game and was evaluated in your office 3 weeks later for persistent pain. there was a soft tissue mass in his distal femur that was tender to touch.

The defects in the bone can be diagnosed by using the X ray technique. The small dose of the ionizing radiation is used to generate the picture of the bone.

The dislocation of the bone or joint can be easily diagnosed with x ray. The X ray never shows the formation of the new bone of the periosteum. The material present inside the bone cannot be diagnosed by the x ray technique used in medical application.

the answer is a) cell division.

hope this !
