What is the main feature of a Grade 2 sprain?

1. Minor stretching of the ligament

2. Partial tearing of the ligament

3. Complete rupture of the ligament

4. Severe bruising without any tearing

The correct answer is: Partial tearing of the ligament

A Grade 2 sprain is characterized by partial tearing of the ligament. This means that there is some degree of damage to the ligament fibers, leading to a loss of stability in the affected joint, along with pain and swelling. In contrast, a Grade 1 sprain would involve minor stretching of the ligament without any tearing, while a Grade 3 sprain denotes a complete rupture of the ligament, resulting in significant instability. Severe bruising without tearing would not adequately represent the underlying injury of a Grade 2 sprain, as this grade specifically implies that the ligament has sustained some degree of injury beyond just inflammation or bruising. Understanding this categorization helps in assessing the severity of ligament injuries and the appropriate management strategies for rehabilitation.
