Common Injuries

Sprains and strains are common injuries that we sustain with daily activities, recreation, and competitive sports. But what is a sprain and what is a strain?

Strains

A strain is the tearing of muscle fibers. Muscle fibers are the individual units that make up your muscles. When you call upon the muscle to perform strong or repeated contractions, you may suffer a strain. To further confuse the layperson, strains are classified intogrades I, II, and III.

Agrade Istrain is a mild disruption of the muscle fibers. There may be mild swelling, mild tenderness, and it may be painful to stretch and use the injured muscle.

Agrade IImuscle strain indicates moderate muscle fiber damage. The pain is moderate to severe, it definitely hurts to use and stretch the injured muscle, and ecchymosis may be present. Ecchymosis (commonly called bruising) indicates that there was internal damage to blood vessels that resulted in bleeding within and around the muscle.

Agrade IIIstrain is the most severe. It is the complete tearing of a muscle into two pieces, or separation of the muscle from its associated tendon. There is severe pain, complete loss of muscle strength, swelling is normally present with ecchymosis, and there may be a palpable “indentation” where the muscle is torn. Medical intervention is ususally necessary. Typically, an orthopaedist will evaluate your condition and surgical repair may be necessary.

Sprains

Sprains are tears of the ligaments and capsules (tissues around joints). Ligaments are made up of bundles of somewhat elastic, collagen tissue and attach one bone to another. Capsules typically partially or completely surround a joint. In a synovial joint, there is lubricating and nourishing fluid within the capsule called synovial fluid. Like strains, sprains are classified asgrade I, II, or IIIin their severity.

Agrade Isprain involves a minimal number of ligament fibers. There may be pain, swelling, and only mild loss of function.

Agrade IIsprain is a moderate or partial ligament tear. There is usually moderate to severe pain, swelling and bruising are typically present, and there is a loss of joint function.

Agrade IIIsprain is a complete tearing of the ligament or joint capsule into two pieces. Severe pain, swelling, bruising, and loss of function are associated with a grade III sprain. As with grade III strains, orthopaedic intervention/surgical repair may be necessary.
