What does a coaptation splint do?

A coaptation splint is specifically designed to stabilize fractures by bringing the fractured limb segments together. Its primary function is to maintain alignment of the fractured bone ends, which is essential for healing and recovery. By keeping the limb in a neutral position and immobilized, the coaptation splint minimizes movement at the fracture site, which can help reduce pain and prevent further injury.

This type of splint is typically applied to limb injuries, especially to long bones, where bringing the two ends of the fracture together is vital for optimal healing.

The other options describe different types of splints or support mechanisms. For example, those extending from ankle to armpit generally refer to a long-arm or long-leg splint, which serves a different purpose than coaptation. The mention of securing the pelvis or the ankle relates to different anatomical regions and types of injury management, which do not align with the primary function of a coaptation splint. By understanding these distinctions, one can see why the coaptation splint primarily focuses on the stability and alignment of limbs, particularly during the healing process.
