Complications are likely to result in cases of excess blood loss or punctures to certain organs, possibly leading to shock. Swelling and bruising may result, more so in high-impact injuries. Pain in the affected areas may differ where severity of impact increases its likelihood and may radiate if symptoms are aggravated when one moves around.

Several precautions may decrease the risk of getting a pelvic fracture. One study that examined the effectiveness of vitamin D supplementation found that oral vitamin D supplements reduced the risk of hip and nonvertebral fractures in older people. Certain types of equipment may help prevent pelvic fractures for the groups which are most at risk.

In terms of overuse injuries a British study found that:

- 40 percent occurred in the fingers

- 16 percent in the shoulders

- 12 percent in the elbows

- 5 percent were the knees

- 5 percent back

- 4 percent wrists

One injury that tend to be very common among climbers is Carpal tunnel syndrome. It is found in about 25% of climbers.

In 2010 national statistics was done by Agency for Healthcare Research and Quality for posterior cruciate ligaments injuries. They found that 463 patients were discharge for having some type of PCL injury. The 18- to 44-year-old age group was found to have the highest injuries reported (figure 1). One reason why this age group consists of the majority of injuries to the PCL is because people are still very active in sports at this age. Men were also reported having more injuries to the PCL (figure 3).

According to the International Classification of Diseases, 9th Revision, Clinical Modification, ICD-9-CM, in 2008 the U.S. listed the diagonsis code for UCL injury as 841.1: Sprain ulnar collateral ligament. There were a total of 336 discharges of UCL injuries. Within the total discharges, separated by age groups: 18- to 44-year-olds; 165 people (49.17%). 45- to 64-year-olds; 91 (27.08%). 65- to 84-year-olds, 65 (19.35%) it shows that the ulnar collateral ligament injuries were more commonly found in men than women. There were 213 men compared to 123 women with ulnar collateral ligament injury. Most of these injuries were also paid through private insurance (170: 50.63%) and Medicare (70: 20.85%). The average estimated cost for the surgery also known as Tommy John surgery is $21,563.

604 injured rock climbers were prospectively evaluated from January 1998 to December 2001, due to the rapid growth of new complex finger trauma in the mid-1980s. Of the most frequent injuries, three out of four were related to the fingers: pulley injuries accounted for 20%, tendovaginitis for 7%, and joint capsular damage for 6.1%.

Isolated and combined posterolateral knee injuries are difficult to accurately diagnose in patients presenting with acute knee injuries. The incidence of isolated posterolateral corner injuries has been reported to be between 13% and 28%. Most PLC injuries accompany an ACL or PCL tear, and can contribute to ACL or PCL reconstruction graft failure if not recognized and treated. A study by LaPrade "et al." in 2007 showed the incidence of posterolateral knee injuries in patients presenting with acute knee injuries and hemarthrosis (blood in the knee joint) was 9.1%.

According to the posterior cruciate ligament injuries only account for 1.5 percent of all knee injuries (figure 2). If it is a single injury to the posterior cruciate ligament that requires surgery only accounted for 1.1 percent compared to all other cruciate surgeries but when there was multiple injuries to the knee the posterior cruciate ligament accounted for 1.2 percent of injuries.

Hand and wrist injuries are reported to account for fifteen to twenty percent of emergency room injuries, and metacarpal fractures represent a significant number of those injuries. Hand injuries of this sort are most prevalent among fifteen- to thirty-five-year-old males, and the fifth metacarpal is the one most commonly affected.

Males are nearly fifty percent more likely to sustain fracture from a punch mechanism than females. Male intentional punch injuries are correlated predominantly with social deprivation, while female punch intentional injuries show more correlation with psychiatric disorders.

Approximately 3.7 male hand injuries, per 1000, per year, and 1.3 female hand injuries, per 1000, per year, have been reported. Common mechanisms of injury are gender specific. Although the fiscal cost is not available, it can be asserted that the cost is reasonably significant per individual, depending on the cost of emergency care, immobilization, surgery, follow up doctors’ visits, etc. in addition to the fiscal impact from loss of and/or limited work abilities.

Scapular fracture is present in about 1% of cases of blunt trauma and 3–5% of shoulder injuries. An estimated 0.4–1% of bone fractures are scapular fractures.

The injury is associated with other injuries 80–90% of the time. Scapular fracture is associated with pulmonary contusion more than 50% of the time. Thus when the scapula is fractured, other injuries such as abdominal and chest trauma are automatically suspected. People with scapular fractures often also have injuries of the ribs, lung, and shoulder. Pneumothorax (an accumulation of air in the space outside the lung), clavicle fractures, and injuries to the blood vessels are among the most commonly associated injuries. The forces involved in scapular fracture can also cause tracheobronchial rupture, a tear in the airways. Fractures that occur in the scapular body are the type most likely to be accompanied by other injuries; other bony and soft tissue injuries accompany these fractures 80–95% of the time. Associated injuries can be serious and potentially deadly, and usually it is the associated injuries, rather than the scapular fracture, that have the greatest effect on the outcome. Scapular fractures can also occur by themselves; when they do, the death rate (mortality) is not significantly increased.

The mean age of people affected is 35–45 years.

Future research into posterolateral injuries will focus on both the treatment and diagnosis of these types of injuries to improve PLC injury outcomes. Studies are needed to correlate injury patterns and mechanisms with clinical measures of knee instability and laxity.

Running is a form of exercise and described as the one of the world's most accessible sport. However, its high-impact nature can lead to injury. Approximately 50% of runners are affected by some form of running injuries or running-related injuries (RRI) annually, and some estimates suggest an even higher frequency. The frequency of various RRI depend on the type of running, as runners vary significantly in factors such as speed and mileage. RRI can be both acute and chronic. Many of the common injuries that plague runners are chronic, developing over a longer period of time, as opposed to injury caused by sudden trauma, such as strains. These are often the result of overuse. Common overuse injuries include stress fractures, Achilles tendinitis, Iliotibial band syndrome, Patellofemoral pain (runners knee), and plantar fasciitis.

Proper running form is important in injury prevention. A major aspect of running form is foot strike pattern. The way in which the foot makes contact with the ground determines how the force of the impact is distributed throughout the body. Different types of modern running shoes are created to manipulate foot strike pattern in an effort to reduce the risk of injury. In recent years, barefoot running has increased in popularity in many western countries, because of claims that it reduces the risk of injury. However, this has not been proven and is still debated.

A study containing 100 consecutive patients with a recent anterior cruciate ligament injury were examined with respect to type of sports activity that caused the injury. Of the 100 consecutive ACL injuries, there were also 53 medial collateral ligament injuries, 12 medial, 35 lateral and 11 bicompartmental meniscal lesions. 59/100 patients were injured during contact sports, 30/100 in downhill skiing and 11/100 in other recreational activities, traffic accidents or at work.

An associated medial collateral ligament tear was more common in skiing (22/30) than during contact sports (23/59), whereas a bicompartmental meniscal lesion was found more frequently in contact sports (9/59) than in skiing (0/30). Weightbearing was reported by 56/59 of the patients with contact sports injuries whereas 8/30 of those with skiing injuries. Non-weightbearing in the injury situation led to the same rate of MCL tears (18/28) as weightbearing (35/72) but significantly more intact menisci (19/28 vs 23/72). Thus, contact sports injuries were more often sustained during weightbearing, with a resultant joint compression of both femuro-tibial compartments as shown by the higher incidence of bicompartmental meniscal lesions. The classic "unhappy triad" was a rare finding (8/100) and Fridén T, Erlandsson T, Zätterström R, Lindstrand A, and Moritz U. suggest that this entity should be replaced by the "unhappy compression injury".

Climber's finger is one of the most common climbing injuries within the sport of rock climbing. It is an overuse injury that usually manifests in a swollen middle or ring finger due to a damaged flexor tendon pulley, normally the A2 or A4 pulley. It is caused by a climber trying to support his or her body weight with one or two fingers, and is particularly common after a repeated utilization of small holds. Continued climbing on an injured finger may result in increased downtime in order to recover.

The consequences of whiplash range from mild pain for a few days (which is the case for most people), to severe disability. It seems that around 50% will have some remaining symptoms.

Alterations in resting state cerebral blood flow have been demonstrated in patients with chronic pain after whiplash injury. There is evidence for persistent inflammation in the neck in patients with chronic pain after whiplash injury.

There has long been a proposed link between whiplash injuries and the development of temporomandibular joint dysfunction (TMD). A recent review concluded that although there are contradictions in the literature, overall there is moderate evidence that TMD can occasionally follow whiplash injury, and that the incidence of this occurrence is low to moderate.

Boxers and other combat athletes routinely use hand wraps and boxing gloves to help stabilize the hand, greatly reducing pain and risk of injury during impact. Proper punching form is the most important factor to prevent this type of fracture.

As many as 50–70% of people who survive traffic accidents have facial trauma. In most developed countries, violence from other people has replaced vehicle collisions as the main cause of maxillofacial trauma; however in many developing countries traffic accidents remain the major cause. Increased use of seat belts and airbags has been credited with a reduction in the incidence of maxillofacial trauma, but fractures of the mandible (the jawbone) are not decreased by these protective measures. The risk of maxillofacial trauma is decreased by a factor of two with use of motorcycle helmets. A decline in facial bone fractures due to vehicle accidents is thought to be due to seat belt and drunk driving laws, strictly enforced speed limits and use of airbags. In vehicle accidents, drivers and front seat passengers are at highest risk for facial trauma.

Facial fractures are distributed in a fairly normal curve by age, with a peak incidence occurring between ages 20 and 40, and children under 12 suffering only 5–10% of all facial fractures. Most facial trauma in children involves lacerations and soft tissue injuries. There are several reasons for the lower incidence of facial fractures in children: the face is smaller in relation to the rest of the head, children are less often in some situations associated with facial fractures such as occupational and motor vehicle hazards, there is a lower proportion of cortical bone to cancellous bone in children's faces, poorly developed sinuses make the bones stronger, and fat pads provide protection for the facial bones.

Head and brain injuries are commonly associated with facial trauma, particularly that of the upper face; brain injury occurs in 15–48% of people with maxillofacial trauma. Coexisting injuries can affect treatment of facial trauma; for example they may be emergent and need to be treated before facial injuries. People with trauma above the level of the collar bones are considered to be at high risk for cervical spine injuries (spinal injuries in the neck) and special precautions must be taken to avoid movement of the spine, which could worsen a spinal injury.

About 25% of people over the age of 50 experience knee pain from degenerative knee diseases.

Management of tendon injuries in the fingers is to follow the RICE method.

- Immediately cease climbing and any other activity that puts stress on the injured finger. Consult a doctor if there is noticeable "bowstringing" on the flexor tendon or if you are the least unsure about the nature of the injury.

- There are different theories out there for the preferred line of approach. Some argue for the use of NSAIDs and ice for visible swelling only, others argue diclofenac sodium should be applied and carefully rubbed in on the injury until the swelling starts to give.

- When the pain and swelling is gone (depending of the grade of the injury, 1–4 weeks), begin with an active healing process – containing squeezing putty clay or a stress ball. Combine this with light massage and mild stretching to ensure your finger will heal properly and better prepared for future stress. The use of heating pads and cold water baths are also mentioned in several sources in order to increase blood flow. Use this therapy for about twice as long as the previous resting period (2–8 weeks) before gradually returning, with the utmost care, to climbing.

- Gradually return to climbing while using prophylactic taping every time you climb, and spend the first weeks climbing relatively easy routes with big holds, good footholds and keep your sessions short and stay away from overhangs and campus areas/boards.

- Return to full-force climbing if easy climbing yields no pain. Continue taping (it will also serve as a mental note of the previous injury) and avoid tweaky crimps and pockets for several months, since complete tendon healing can take 100 days or more.

The UCL is important because it stabilizes the elbow from being abducted. If intense or repeated bouts of valgus stress occur on the UCL, injury will most likely transpire. Damage to the ulnar collateral ligament is common among baseball pitchers and javelin throwers because the throwing motion is similar. Physicians believe repetitive movements, especially pitching in baseball, cause adolescents' UCL injuries. Furthermore, physicians have stated that if an adolescent throws over 85 throws for 8 months or more in a year, or throw when exhausted, the adolescent has a significantly higher risk of succumbing to a UCL surgery. Gridiron football, racquet sports, ice hockey and water polo players have also been treated for damage to the ulnar collateral ligament. Specific overhead movements like those that occur during baseball pitching, tennis serving or volleyball spiking increase the risk of UCL injury. During the cocking phase of pitching, the shoulder is horizontally abducted, externally rotated and the elbow is flexed. There is slight stress on the UCL in this position but it increases when the shoulder is further externally rotated. The greater the stress the more the UCL is stretched causing strain. During the overhead throwing motion, valgus stress on the medial elbow occurs during arm cocking and acceleration. The initiation of valgus stress occurs at the conclusion of the arm-cocking phase. In the transitional moment from arm cocking to arm acceleration, the shoulder vigorously rotates internally, the forearm is in near full supination, and the elbow flexes from 90° to approximately 125°. From late cocking to ball release, the elbow rapidly extends from approximately 125° to 25° at ball release. This causes tremendous valgus stress and tensile strain on the UCL. Injuries to the ulnar collateral ligament are believed to result from poor throwing mechanics, overuse, high throwing velocities, and throwing certain types of pitches, such as curveballs. Poor mechanics along with high repetition of these overhead movements can cause irritation, micro-tears or ruptures of the UCL. Injuries to the Ulnar Collateral Ligament in baseball players are rarely due to one-time, traumatic events. Rather, they are more often due to small chronic tears that accumulate over time.

Tibia shaft fractures are the most common long bone fractures. They account for approximately 4% of the fractures seen in the Medicare population.

Tibial plateau fractures constitute 1% of all fractures. Peak age is 30–40 years old in men and 60-70 in women. Approximately half of the people who sustain a tibial plateau fracture are aged over 50 years old.

Injury mechanisms such as falls, assaults, sports injuries, and vehicle crashes are common causes of facial trauma in children as well as adults. Blunt assaults, blows from fists or objects, are a common cause of facial injury. Facial trauma can also result from wartime injuries such as gunshots and blasts.

Animal attacks and work-related injuries such as industrial accidents are other causes. Vehicular trauma is one of the leading causes of facial injuries. Trauma commonly occurs when the face strikes a part of the vehicle's interior, such as the steering wheel. In addition, airbags can cause corneal abrasions and lacerations (cuts) to the face when they deploy.

Because of the high frequency of associated injuries, clinicians are taught to suspect that a patient has multiple severe injuries if a sternal fracture is present. Sternal fracture is commonly associated with injuries to the heart and lungs; if a person is injured with enough force to fracture the sternum, injuries such as myocardial and pulmonary contusions are likely. Other associated injuries that may occur include damage to blood vessels in the chest, myocardial rupture, head and abdominal injuries, flail chest, and vertebral fracture. Sternal fractures may also accompany rib fractures and are high-energy enough injuries to cause bronchial tears (ruptures of the bronchioles). They may hinder breathing. Due to the associated injuries, the mortality rate for people with sternal fracture is high, at an estimated 25–45%. However, when sternal fractures occur in isolation, their outcome is very good.

There is controversy over the question of whether the presence of sternal fracture is an indication of cardiac injuries.

About 1.8 million people go to the emergency department each year due to hand injuries.
