When assessing a limb after fracture reduction, which aspect is MOST critical to check?

When assessing a limb after fracture reduction, examining skin color and temperature is crucial because these indicators can provide immediate information about blood flow and circulation to the extremity. Adequate circulation is essential for healing, and changes in skin color—such as pallor or cyanosis—along with temperature variations, can signal potential complications like compartment syndrome or impaired blood supply. These conditions can arise from swelling, tight bandaging, or misalignment after the fracture has been reduced.

While assessing range of motion, strength against resistance, and size compared to the opposite limb are important, they are secondary to the immediate assessment of circulation. Ensuring that the limb has good perfusion is vital for the healing process and for preventing permanent damage to the tissues. Thus, monitoring skin color and temperature provides essential insights into the ongoing viability of the affected limb following a fracture reduction.
