For a 1st metatarsal fracture in a child, CRPP is typically considered when which factor prevents reduction?

Explanation:
Soft-tissue interposition can block reduction. In a child’s first metatarsal fracture, the sesamoid apparatus sits under the metatarsal head and can become trapped between fracture fragments, making a true closed reduction impossible. When this interposition prevents alignment, a percutaneous closed reduction with pin fixation is considered to achieve and maintain alignment with minimal invasion. Open reduction would be pursued if there were an open fracture, and non-displaced fractures typically don’t require fixation. Nonunion risk isn’t the reason for choosing this approach.
