It is called the traumatic tear (cross section) of various ligaments of the joint, but without fracture of the bones. Sometimes, an ankle sprain coexists with a bone fracture, so it is a mixed traumatic injury.

There are 3 degrees of sprain:

1st degree sprains: Slight tear, sprain of ligaments

2nd degree sprains: Partial rupture of the ligaments

3rd degree sprains: Complete rupture of the ligaments

Symptoms: Pain, edema (swelling), stiffness, lameness (the person limps) and hematoma (2nd + 3rd degree)
