Pediatric Sprains and Strains - An Overview

Introduction:

An active lifestyle can make people prone to injuries, and this is especially true among children who indulge in sports and other kinds of physical activity. This can make them easily vulnerable to sprains and strains secondary to an injury due to physical exertion. Since they are a major cause of pain in children, managing sprains and strains should be done efficiently to help the children recover from them as soon as possible.

What Are Sprains and Strains in Children?

When a child suffers an injury, two types of reactions can occur in the child’s body, resulting in injuries to muscles and tendons or ligaments.

Strains:

When the connecting fibrous tissues between the bones and muscles (tendons) are injured, the surrounding tissues tend to overstretch or tear in children. This is a pediatric strain.

Sprains:

When the affected child’s ligaments (firm bands of tissue that connect bones) are injured, it results in a sprain.

What Causes Pediatric Sprains and Strains?

• Overexertion of the child during sports activities.

• Exercising and playing sports without proper warm-up.

• Lifting heavy objects suddenly.

• Sudden jerky movements.

• Falls that injure an already overstretched muscle or tendon.

• Twisting injuries (injuries that occur when there is heavy tension on one particular point of a ligament). This is common with sports activities like soccer or gymnastics.

• Direct collision with hard objects during a physical activity.

• Putting pressure on injured fibrous tissues.

What Is the Pathophysiology of Pediatric Sprains and Strain?

In strains, the pathophysiology begins with the overstretching or tearing of muscle fibers or tendons due to excessive force or overuse. This leads to micro-tears or, in severe cases, complete ruptures, initiating an inflammatory response within the injured area. The damaged tissues tend to release mediators like cytokines that exacerbate the inflammatory process and facilitate the repair process of the tissue at the same time.

In sprains, the mechanism involves the excessive stretching or tearing of ligaments caused by a sudden twist, fall, or impact that forces a joint beyond its normal range of motion. This disruption of ligamentous fibers results in joint instability and can damage surrounding blood vessels, leading to hemorrhage and edema within the joint capsule. The inflammatory response in sprains mirrors that of strains, with the release of similar mediators. In both injuries, the body's repair process involves the formation of scar tissue, which may restore structural integrity but can also reduce the flexibility and strength of the affected tissues.

What Are the Symptoms of Pediatric Sprains and Strains?

• Immediate pain soon after the injury to muscle or tendon.

• Tenderness in the affected region.

• Swelling.

• Erythema (redness) indicates localized inflammatory action.

• The injured area may have bruises.

• Muscle contractions can occur involuntarily, which exacerbates the existing pain.

• Difficulty in moving the joint.

• Stiffness.

• Limited motion and range of action.

• Reduced flexibility of the affected region.

• The affected area becomes weak.

• Inability to bear weight.

• In cases of pediatric sprains, the erythema and swelling tend to increase gradually over a period of the next two days.

• The affected children may have a sensation of the joint being unstable or wearing away.

• Some children may report a popping or snapping sensation at the time of injury.

Severity Grades of Pediatric Sprains and Strains:

Mild (Grade I):

• Minimal stretching or microscopic tearing of the bands of muscle fibers or ligaments.

• Mild pain and tenderness.

• Slight swelling of the affected area.

• Minimal loss of function.

Moderate (Grade II):

• Partial tearing of muscle fibers or ligaments.

• Moderate pain and swelling.

• Bruising in and around the injured area.

• Noticeable loss of function.

• Difficulty bearing weight or using the affected area.

Severe (Grade III):

• Complete tear or rupture of muscle fibers or ligaments.

• Severe pain and significant swelling.

• Extensive bruising.

• Complete instability of the affected area.

• Inability to use the affected muscle or joint.

How to Diagnose Pediatric Sprains and Strains?

• Asking the child about the history of injury and the activity involved can give a major view of the type of injury that the child has served.

• Physical examination of the injured area will give details about the severity of pain, swelling, and also helps in grading the injury.

• Tenderness can also be elicited during palpation of the injured region.

• Generally, during the time of examination, the color changes will be noted to identify and locate the bruises and associated inflammation in the surrounding area.

• To look for strains in the ligaments in children, X-rays will be advised. To know about the damage that occurred in the muscles and soft tissues, MRI will be taken.

How to Manage Pediatric Sprains and Strains?

The first line of treatment option for sprains and strains in children is

• Rest.

• Ice.

• Compressions.

• Elevation.

Other management options are:

• Pain killers.

• Restricting the usage of the injured muscles and ligaments.

• Avoiding heavy object usage.

• Physical therapy, like exercises.

• Use of ultrasound or electrical stimulation.

• Grade III injuries require the use of casts or splints to make the injured area immobile.

How to Prevent Sprains and Strains in Children?

• Children should be encouraged to engage in a thorough warm-up before initiating physical activities to increase blood flow to muscles and improve flexibility of all the muscles and ligaments of the body.

• Dynamic stretches that mimic the actual physical activity should be incorporated as a part of the activity to help in getting the muscles and ligaments accustomed to the activity.

• Using proper equipment, like well-fitted shoes and ankle braces, is the best way to prevent sprains and strain in children.

• Strength training and conditioning exercises should be mandatory components of physical activity for children to improve their muscle and tendons' resilience.

• Children should be taught to know about the right balance of core structures and proprioception during the activities so that they will be mindful of their actions during exertion.

• Children and young adolescents are the ones who suffer from strains and sprains frequently and educating them about the effects of overexertion and signs of fatigue is very important.

Conclusion:

Children who suffer from strains and sprains tend to also have a negative psychological impact, which should be overcome by positive reinforcement. Incorporating psychological counseling and skill training specifically for a particular physical activity can help children combat the pain associated with strains and sprains easily.
