What should you do if a patient cannot extend their leg after an injury?

When a patient is unable to extend their leg after an injury, the correct approach is to use a bent knee splint. This method provides support while accommodating any swelling or muscle spasms that may have occurred due to the injury. A bent knee splint helps to minimize pain and stabilize the leg in a comfortable position, which can be particularly important if the injury involves damage to the ligaments, tendons, or muscles around the knee or thigh.

Applying a straight splint in this scenario may not provide the necessary comfort or support because it could put further stress on the injured area, potentially exacerbating the condition. Encourage movement is generally not advisable in acute injuries, as unnecessary movement can lead to further damage and increased pain. Leaving the leg as is would not provide any support, and the risk of worsening the condition or causing additional injury is high. Thus, using a bent knee splint ensures that the patient is stabilized properly while reducing the risk of exacerbating their injury.
