Anatomy of Hand X-rays_Revised

Dr. Morton explains the anatomy visible in hand X-rays, focusing on PA, oblique, and lateral views. The PA view highlights carpals, metacarpals, and phalanges, useful for diagnosing arthritis. Carpal bones are detailed with a mnemonic for memorization. Metacarpals and phalanges are discussed, including their joints. Oblique and lateral views are examined for overlapping bones and potential fractures.
