In the context of splinting a closed, angulated fracture, moving the limb from its found position carries the risk of converting the injury into an open fracture. An open fracture occurs when the bone breaks through the skin, which can lead to increased exposure to infection and significant complications. When a limb is angulated, it may imply that the bone is misaligned but still contained within the skin; manipulations could force the bone through the skin, making a previously closed fracture open.

Other considerations that factor into this decision include the potential for loss of circulation and increased pain. While movement can indeed cause pain or even risk compromising blood flow due to further displacement, the primary concern in the scenario provided is the potential for changing a closed fracture into an open one. Hence, ensuring minimal movement is crucial to maintain the integrity of the injury and prevent worsening the condition.
