Answer

Radiography rarely is indicated in TF. [5] Hand radiographs are performed only if abnormal pathology (eg, abnormal sesamoids, loose bodies in the metacarpophalangeal [MCP] joint, osteoarthritic spurs on the metacarpal head, or avulsion injuries of collateral ligaments) is suspected.

Radiographs are helpful to exclude osteoarthritis, fracture malunion, foreign body, or a large sesamoid bone that is affecting interphalangeal (IP) joint motion.
