Characterized by rapid onset resulting from a traumatic event

Obvious, clearly identifiable causative mechanism

Usually associated with a significant traumatic event

Characterized by a slow, insidious onset

Lack of proper conditioning

Uneven playing surfaces

Heat and humidity

Improper shoes

Concentric contraction

Static (isometric) contraction

Isokinetic contraction

Eccentric contraction

Tendon

Ligament

Cartilage

Bone

Includes injuries that result in permanent disability

Involves damage to the brain and/or spinal cord and is potentially life threatening

Typically results in death of the participant

Caused by systemic failure related to exertion or by secondary complication

It involves ligament tissue.

A third-degree sprain is the least severe form.

No hemorrhage is associated with a third-degree sprain.

Second-degree sprains rarely recur.

This injury involves ligament tissue.

This injury involves tissues such as tendon, muscle, and the musculotendinous junction.

First-degree strains are the most severe form of this injury.

Third-degree strains involve little associated damage to muscle and tendon structures.

Hematoma

Ecchymosis

Myositis ossificans

Subluxation

This injury occurs when bone is subjected to repeated episodes of overloading that exceed the rate of recovery.

There is usually an absence of trauma in the presence of symptoms.

Typically the athlete with a stress fracture is involved in a repetitive activity.

Stress fractures are easily diagnosed in the initial phase with a standard X-ray.

Premature closure of the growth plate

Decreased bone mineralization

Partial displacement of joint

MRSA Infection

May present many of the same signs and symptoms of sprains

May involve a subluxation, which is a partial displacement of the bones in a joint

May involve a luxation, which is a total displacement of bones that compose a joint

Is generally acceptable for coaching personnel to reduce a dislocation in the field without medical assistance

The aggregate rate for boys’ sports was higher than for girls’ sports.

Boys had a higher knee ligament injury rate in soccer than girls.

Boys’ game injury rate was five times greater than for girls.

The aggregate rate for girls’ sports was higher than for boys’ sports.

Medial ankle sprains and lateral collateral ligament sprains of the knee were the most common injuries.

The rate of concussions was lower in competitions than in practice.

Fatalities have increased over the last few decades due to the lack of implementation of various rules.

College football accounts for 75% of the exertional heat illness (EHI) cases across all NCAA sports.

Best to treat with the “run-it-off” approach

Coaches are most often the first to arrive at the scene of an injury.

Determine if athlete is faking injury by asking questions

Treat all injuries with ice and crutches.
