A sprain is a sudden stretching of the ligaments of a joint and is associated with pain and usually discoloration, which appears early from hemorrhage into the tissue. The ligaments sometimes become tense and get injured near the weak joints and bones. Sprain may occur joints like knee, ankle, elbow joints etc.
The sprain may be classified into.
(a) Mild Sprain: In this type of sprain there is slight tearing of some of the ligament fibres and there is no loss of function of joint.
(b) Moderate Sprain: In this type of sprain there is some rupture of ligaments and ther is some loss of function.
(c) Severe sprain: In this type of sprain there is total rapture of ligament and they are also separated from bone and total loss of any movement.
