CLO09: Identify structures demonstrated on routine radiographic images.
Image: PA Oblique Hand
For a PA oblique hand, certain criteria are required to be fulfilled in order to classify it as such. Several of these criteria needed include having anatomy from fingertips to the distal radius and ulna, forty-five degree rotation of anatomy, open metacarpophalangeal (MCP) joints, open interphalangeal (IP) joints and partial superimposition of third, fourth and fifth metacarpal bases. A PA oblique hand can also be identified by whether the digits have concavity on only one or both sides of the digit.
