A little girl has seriously injured one of her hands after getting it stuck in playground equipment.

The five-year-old was at a playground in Strathfield, in Sydney's Inner West, when her hand was trapped in a carousel.

A crew from Burwood Fire Station rushed to the playground just before 1.30pm, Fire and Rescue NSW (FRNSW) said.
