COMMON ANKLE INJURIES ACUTE ANKLE SPRAIN An ankle sprain occurs when the foot suddenly twists or rolls and forces the ankle out of its normal position. In addition to pain, you may experience swelling, bruising, and additional discomfort when you try to put weight on your foot.
There are several levels of ankle sprain:
Grade I Sprain (Mild) • Slight stretching and microscopic tearing of the ligament fibers • Mild tenderness and swelling around the ankle
Grade II Sprain (Moderate) • Partial tearing of the ligament
• Moderate tenderness and swelling around the ankle • When the ankle moves in certain ways, there is an abnormal looseness of the ankle joint
Grade III Sprain (Severe) • Complete tear of the ligament
• Significant tenderness and swelling around the ankle • When the ankle moves in certain ways, substantial instability occurs
