The radiographic views commonly used to assess bone age are

• A. Left Wrist And Knee
• B. Chest And Abdomen
• C. Skull And Jaw
• D. Pelvis And Hip

Answer: (A)

Bone age is determined by examining skeletal maturity on radiographs and comparing what you see to established reference standards. The left hand and wrist provide the most informative, standardized set of growth markers because many bones there ossify in a regular, well-documented sequence over a wide age range. An AP view of the left hand and wrist shows the phalanges, metacarpals, carpals, and the distal radius and ulna, whose sizes and the status of their growth plates change predictably with age. This consistency across patients and observers is why the left hand and wrist radiographs are the preferred method for age estimation, with widely used references like Greulich and Pyle or Tanner-Whitehouse.

Other regions—the chest and abdomen, skull and jaw, or pelvis and hip—do not provide the same reliable benchmarks for skeletal maturity, so they aren’t used for standard bone age assessment. The knee is not the commonly used site for this purpose, though in some cases alternative images may be considered if the hand is unavailable.
