The most crucial factor when splinting a suspected extremity fracture is ensuring proper distal neurovascular function. This involves assessing circulation, sensation, and movement in the area beyond the fracture site. The purpose of this assessment is to establish a baseline for capillary refill, pulse presence, and sensory responses before applying the splint. After splinting, it is equally important to check these functions again to confirm that the splint has not compromised blood flow or nerve function. Any signs of compression, such as a loss of pulse or altered sensation, can indicate that the splint is too tight or improperly applied, necessitating immediate adjustment.

While other considerations, such as immobilizing joints and positioning ties, contribute to effective splinting, they do not take precedence over the assessment of neurovascular status. Monitoring the distal region for any changes in neurovascular function is key to ensuring the safety and effectiveness of the splinting process, which is why this aspect is highlighted as most important.
