Sports injury
Sports injuries are injuries that occur during sport, athletic activities, or exercising. In the United States, there are approximately 30 million teenagers and children combined who participate in some form of organized sport. Of those, about three million athletes age 14 years and under experience a sports injury annually. According to a study performed at Stanford University, 21 percent of the injuries observed in elite college athletes caused the athlete to miss at least one day of sport, and approximately 77 percent of these injuries involved the lower leg, ankle, or foot. In addition to those sport injuries, the leading cause of death related to sports injuries is traumatic head or neck occurrences. When an athlete complains of pain or an injury, the key to a diagnosis is to obtain a detailed history and examination. An example of a format used to guide an examination and treatment plan is a S.O.A.P note or, subjective, objective, assessment, plan. Another important aspect of sport injury is prevention, which helps to reduce potential sport injuries. It is important to establish sport-specific dynamic warm-ups, stretching, and exercises that can help prevent injuries common to each individual sport. Creating an injury prevention program also includes education on hydration, nutrition, monitoring team members “at risk”, monitoring at-risk behaviors, and improving technique. Season analysis reviews, preseason screenings, and pre-participation examinations are also essential in recognizing pre-existing conditions or previous injuries that could cause further illness or injury. One technique that can be used in the process of preseason screening is the functional movement screen. The functional movement screen can assess movement patterns in athletes in order to find players who are at risk of certain injuries. In addition, prevention for adolescent athletes should be considered and may need to be applied differently than adult athletes. Lastly, following various research about sport injury, it is shown that levels of anxiety, stress, and depression are elevated when an athlete experiences an injury depending on the type and severity of the injury.
Types of sport injury
Nearly two million people every year suffer sports-related injuries and receive treatment in emergency departments. Fatigue is a large contributing factor that results in many sport injuries. There are times where an athlete may participate on low energy leading to the deterioration in technique or form, resulting in a slower reaction time, loss in stability of muscle joints, and allowing an injury to occur. For both sexes the most common areas injured are the knee and ankle, with sprains/strains being the most common areas for injury. Injuries involving the patellofemoral articulation are significantly more frequent among females. The sport with the highest injury rate is football, with greater than 12 times the number of injuries seen in the next most common sport.Soft tissue injuries
When soft tissue experiences trauma the dead and damaged cells release chemicals, which initiate an inflammatory response. The small blood vessels that are damaged become dilated which produce bleeding within the tissue. The body's normal response includes forming a small blood clot in order to stop the bleeding and allows a clot of special cells, called fibroblasts, to form. This begins the healing process by laying down scar tissue. Therefore, the inflammatory stage is the first phase of healing. However, too much of an inflammatory response in the early stage can indicate that the healing process takes longer and a return to activity is delayed. Sports injury treatments are intended to minimize the inflammatory phase of an injury, so that the overall healing process is accelerated. Intrinsic and extrinsic factors are determinant for the healing process.Soft tissue injuries can be generally grouped into three categories: contusions, abrasions and lacerations. Contusions or bruises are the simplest and most common soft tissue injury and is usually a result of blunt force trauma. Severe contusions may involve deeper structures and can include nerve or vascular injury. Abrasions are superficial injuries to the skin no deeper than the epidermis tissue layer, and bleeding, if present, is minimal. Minor abrasions generally do not scar, but deeper abrasions generally bleed and may scar. Lastly, sports-related lacerations are caused by blunt trauma and result in burst-type open wounds, often with jagged irregular edges. Facial lacerations are the most variable of the soft tissue injuries that athletes can sustain. They can occur intraorally and extraorally, vary from a superficial skin nick to a through and through lip laceration, or involve significant vascular disruption or injury to collateral vital structures.
Hard tissue injuries
Types of hard tissue injuries can include dental and bone injuries and are less frequent than soft tissue injuries in sport, but are often more serious. Hard tissue injuries to teeth and bones can occur with contusions, such as Battle sign, which indicates basilar skull fracture, and so-called raccoon eyes, which indicate mid-face fractures. However, tooth fractures are the most common type of tooth injury, and can be categorized as crown infractions, enamel-only fracture, enamel-dentin fractures, and fractures that extend through the enamel and dentin into the pulp which are defined below.- Crown infractions are characterized by a disruption of the enamel prisms from a traumatic force, these injuries typically present as small cracks that affect only the enamel.
- Enamel-only fractures are mild and often appear as roughness along the edge of the tooth crown. These injuries typically can go unnoticed by the athlete as they are usually not sensitive to the touch or to temperature changes. Enamel-only fractures are not considered dental emergencies and immediate care is not needed.
- Enamel-Dentin crown fractures typically present as a tooth fracture confined to enamel and dentin with loss of tooth structure, but not exposing the pulp. The athlete often will report sensitivity to air, cold or touch, but the athlete can return to play as tolerated and referral can be delayed up to 24 hours.
- Enamel-Dentin-Pulp fractures extend through the enamel and dentin and into the pulp. If the pulp is vital, a focal spot of hemorrhage will be noticeable within the yellow dentin layer and the athlete may report acute pain. Referral to a trauma-ready dentist should occur as soon as possible.
Overuse injuries
Overuse injuries can be defined as injuries that result from a mechanism of repetitive and cumulative micro-trauma, without a specific onset incident. Rapid changes in physical growth can make children vulnerable to overuse injuries, and these types of injuries are increasing among youth populations. Overuse injuries can usually be classified into 4 types/stages, these include:- Pain in the affected area during activity
- Pain in the affected area during activity
- Pain in the affected area after activity
- Chronic pain in the affected area, even after resting
Head and neck injuries
Head and neck injuries can include a variety of pathologies from sprains, strains and fractures to traumatic brain injuries and spinal cord injuries. Sprains and strains can occur from an abrupt rotation or whipping motion, such as whiplash. Stress injuries of the lumbosacral region are one of the causes of sports-related lower back pain in young individuals. The onset of the observed cervical fractures in sports injury were likely due to continued momentum that transferred loads superiorly through the neck, which likely exacerbated the injuries the injuries to the occipital condyles and the upper cervical vertebrae. Researchers have reported that 3-25% of cervical spine injuries actually occur after the initial traumatic event and are caused or exacerbated by improper handling during early stages of management or patient transport. One of the more common head or neck injuries that occurs in sports is a concussion. A concussion is a type of mild traumatic brain injury resulting in a chemical change in the brain and has potential to cause damage to brain tissue. This can occur when a person sustains a hit or blow that cause the head and brain to move quickly, causing the brain to bounce in the skull. According to an epidemiological study published in the Journal of Athletic Training, the incidence of concussions from 27 high school sports was 3.89 sports-related concussions per 10,000 athlete exposures.Risk factors
Prevention
helps reduce potential sport injuries and provides several benefits. Some benefits include a healthier athlete, longer duration of participation in the sport, potential for better performance, and reduced medical costs. Explaining the benefits to participate in sports injury prevention programs to coaches, team trainers, sports teams, and individual athletes will give them a glimpse at the likelihood for success by having the athletes feeling they are healthy, strong, comfortable, and capable to compete.Primary, secondary, and tertiary prevention
can be broken up into three broad categories of primary, secondary, and tertiary prevention. Primary prevention involves the avoidance of injury. An example is ankle braces being worn as a team, even those with no history of previous ankle injuries. If primary prevention activities were effective, there would be a lesser chance of injuries occurring in the first place. Secondary prevention involves an early diagnosis and treatment should be acquired once an injury has occurred. The goal of obtaining early diagnosis is to ensure that the injury is receiving proper care and recovering correctly, therefore limiting the concern for other medical problems to stem from the initial traumatic event. Lastly, tertiary prevention is solely focused on the rehabilitation to reduce and correct an existing disability resulting from the traumatic event. An example in the case of an athlete who has obtained an ankle injury the rehabilitation would consist of balance exercises to acquire the strength and mobility back as well as wearing an ankle brace, while gradually returning to the sport.Season analysis
It is most essential to establish participation in warm-ups, stretching, and exercises that focus on main muscle groups commonly used in the sport of interest. Participation in these events decreases the chances for getting muscle cramps, torn muscles, and stress fractures. A season analysis is one of the beneficial reviews for preventing player sport injuries. A season analysis is an attempt to identify risks before they occur by reviewing training methods, the competition schedule, traveling, and past injuries. If injuries have occurred in the past, the season analysis reviews the injury and looks for patterns to see if it may be related to a specific training event or competition program. For example, a stress fracture injury on a soccer team or cross country team may be correlated to a simultaneous increase in running and a change in running environment, like a transition from a soft to hard running surface. A season analysis can be documented as team-based results or individual athlete results. Other key program events that have been correlated to injury incidences are changes in training volume, changes in climate locations, selection for playing time in important matches, and poor sleep due to tight chaotic scheduling. It is important for team program directors and staff to implicate testing in order to ensure healthy, competitive, and confidentPreseason screening
Another beneficial review for preventing player sport injuries is preseason screenings. A study found that the highest injury rate during practices across fifteen Division I, II, and III NCAA sports was in the preseason compared to in-season or postseason. To prepare an athlete for the wide range of activities needed to partake in their sport pre-participation examinations are regularly completed on hundreds of thousands of athletes each year. It is extremely important that the physical exam is done properly in order to limit the risks of injury and also to diagnose early onsets of a possible injury. Preseason screenings consist of testing the mobility of joints, testing the stability of joints, testing the strength and power of muscles, and also testing breathing patterns. The objective of a preseason screening is to clear the athlete for participation and verify that there is no sign of injury or illness, which would represent a potential medical risk to the athlete. Besides the physical examination and the fluidity of the movements of joints the preseason screenings often takes into account a nutrition aspect as well. It is important to maintain normal iron levels, blood pressure levels, fluid balance, adequate total energy intake, and normal glycogen levels. Nutrition can aid in injury prevention and rehabilitation, if one obtains the body's daily intake needs. Obtaining sufficient amount of calories, carbohydrates, fluids, protein, and vitamins and minerals is important for the overall health of the athlete and limits the risk of possible injuries. Iron deficiency, for example, is found in both male and female athletes; however 60 percent of female college athletes are affected by iron deficiency. There are many factors that can contribute to the loss in iron, like menstruation, gastrointestinal bleeding, inadequate iron intake from the diet, general fatigue, weakness, among others. The consequences of iron deficiency, if not solved, can be an impaired athletic performance and a decline in immune and cognitive function.Functional movement screen
One technique used in the process of preseason screening is the functional movement screen. Functional movement screening is an assessment used to evaluate movement patterns and asymmetries, which can provide insight into mechanical restrictions and potential risk for injury. Functional movement screening contains seven fundamental movement patterns that require a balance of both mobility and stability. These fundamental movement patterns provide an observable performance of basic locomotor, manipulative, and stabilizing movements. The tests place the individual athlete in extreme positions where weaknesses and imbalances become clear if proper stability and mobility is not functioning correctly. The seven fundamental movement patterns are a deep squat, hurdle step, in-line lunge, shoulder mobility, active straight-leg raise, trunk stability push-up, and rotary stability. For example, the deep squat is a test that challenges total body mechanics. It is used to gauge bilateral, symmetrical, and functional mobility of the hips, knees, and ankles. The dowel held overhead gauges bilateral and symmetrical mobility of the shoulders and the thoracic spine. The ability to perform the deep squat technique requires appropriate pelvic rhythm, closed-kinetic chain dorsiflexion of the ankles, flexion of the knees and hips, extension of the thoracic spine, as well as flexion and abduction of the shoulders. There is a scoring system applied to each movement as follows a score of 3 is given to the athlete if they can perform the movement without any compensations, a score of 2 is given to the athlete if they can perform the movement, but operate on poor mechanics and compensatory patterns to achieve the movement, a score of 1 is given to the athlete if they cannot perform the movement pattern even with compensations, and finally, a 0 is given to the athlete if one has pain during any part of the movement or test. Three of the seven fundamental tests including shoulder mobility, trunk stability push-up, and rotary stability have a clearance scoring associated with them meaning a pass or fail score. If the athlete fails this part of the test a score of 0 is given as the overall score. Once the scoring is complete the athlete and medical professional can review the documentation together and organize a set prevention program to help target and strengthen the areas of weakness in order to limit the risks of possible injuries.Sport injury prevention for children
There are approximately 8,000 children treated in emergency rooms each day for sports-related injures. It is estimated that around 1.35 million kids will suffer a sports-related injury per year worldwide. This is why children and adolescents need special attention and care when participating in sports.According to the Centers for Disease Control and Prevention, many sports-related injuries are predictable and preventable. Some prevention techniques are listed below.
- Exercise-based injury prevention has shown to reduce injury rates in sports. Sport-specific warm-up programs exist which have proven efficacious in reducing injury rines of children.
- Warming up improves the blood flow in muscles and allows for the muscle temperature to rise which helps to prevent muscle strains or tears.
- Provide children the right equipment for sport like helmets, shin guards, ankle braces, gloves and others to prevent injuries.
- Have breaks and drink water as well to keep them hydrated.

Costs
Interventions targeted at decreasing the incidence of sports injuries can impact health-care costs, as well as family and societal resources. Sports injuries have direct and indirect costs. The direct costs are usually calculated by taking into account the cost of using healthcare resources to prevent, detect and treat injury. There is a need for research about how healthcare is used and the expenses that coincide with it. Included in these expenses are how different injuries may have different prognoses. Indirect costs may be taken into account as well, when an injury prevents an individual from returning to work it may hinder the economic benefit to themselves and others.For collegiate athletics, the estimated cost of sport injuries ranges from $446 million to $1.5 billion dollars per year. For high school athletics, the yearly estimated cost of sport injuries ranges from $5.4 billion to $19.2 billion. Medical costs in the United States for sports injury related emergency department visits exceeded $935 million dollars every year.
