Extreme pain, loss of function, and severe instability describe which ligament sprain grade?

• A. Ligament Sprain Grade III
• B. Contusion
• C. Hematoma
• D. Ligament Sprain Grade I

Answer: (A)

In ligament injuries, grading reflects how much damage the ligament has sustained and how unstable the joint becomes. A Grade III sprain means a complete rupture of the ligament, leading to severe instability and a significant loss of function. The signs described—extreme pain, inability to function, and severe instability—point to a full tear rather than just a stretch or partial tear. A mild Grade I sprain would have minimal swelling and function loss, and a Grade II would be a partial tear with more swelling and reduced function but not the marked instability seen in a complete rupture. Contusion or hematoma describe bruising or a collection of blood, not the level of ligament damage or instability involved in a sprain grade.
