Damage to the flexor tendon pulleys that encircle and support the tendons that cross the finger joints is the most common finger injury within the sport (see climber's finger).

The main culprit for pulley related injuries is the common crimp grip, especially in the closed position. The crimp grip requires a near ninety-degree flexion of the middle finger joint, which produces a tremendous force load on the A2 pulley. Injuries to the A2 pulley can range from microscopic to partial tears and, in the worst case, complete ruptures. Some climbers report hearing a pop, which might be a sign of a significant tear or complete rupture, during an extremely heavy move (e.g. tiny crimp, one- or two-finger pocket). Small partial tears, or inflammation can occur over the course of several sessions.

- Grade I – Sprain of the finger ligaments (collateral ligaments), pain locally at the pulley, pain when squeezing or climbing.

- Grade II – Partial rupture of the pulley tendon. Pain locally at the pulley, pain when squeezing or climbing, possible pain while extending your finger.

- Grade III – Complete rupture of the pulley, causing bowstringing of the tendon. Symptoms can include: Pain locally at the pulley (usually sharp), may feel/hear a 'pop' or 'crack', swelling and possible bruising, pain when squeezing or climbing, pain when extending your finger, pain with resisted flexion of the finger.

Shoulder related injuries include rotator cuff tear, strain or tendinitis, biceps tendinitis and SLAP lesion.

The symptoms are pain and tenderness in the specific location of the hand, which corresponds to the metacarpal bone around the knuckle. When a fracture occurs, there may be a snapping or popping sensation. There will be swelling of the hand along with discoloration or bruising in the affected area. Abrasions or lacerations of the hand are also likely to occur. The respective finger may be misaligned, and movement of that finger may be limited and painful.

Patients often complain of pain and instability at the joint. With concurrent nerve injuries, patients may experience numbness, tingling and weakness of the ankle dorsiflexors and great toe extensors, or a footdrop.

As these are colloquial terms, texts and medical dictionaries do not universally agree on precise meanings. Various authorities state that a "boxer's fracture" means a break in specifically the second metacarpal bone or third metacarpal bone, with "bar room fracture" being specific to the fourth metacarpal bone or fifth metacarpal bone. Though some writers assert that boxer's fracture and bar room fracture are distinct terms representing injuries to different bones, this distinction seems to have been lost and most medical professionals now describe any metacarpal fracture as a "boxer's fracture" .

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.

Finger injuries are usually diagnosed with x-ray and can get to be considerably painful. The majority of finger injuries can be dealt with conservative care and splints. However, if the bone presents an abnormal angularity or if it is displaced, one may need surgery and pins to hold the bones in place.

Patellofemoral pain syndrome is associated with pain in the knee and around the patella. It is sometimes referred to as runner's knee, but this term is used for other overuse injuries that involve knee pain as well. It can be caused by a single incident, but is often the result of overuse or a sudden icrease in physical activity.

As with other types of fractures, scapular fracture may be associated with pain localized to the area of the fracture, tenderness, swelling, and crepitus (the crunching sound of bone ends grinding together). Since scapular fractures impair the motion of the shoulder, a person with a scapular fracture has a reduced ability to move the shoulder joint. Signs and symptoms may be masked by other injuries that accompany the scapular fracture.

Patients often complain of pain and swelling over the medial aspect of the knee joint. They may also report instability with side-to-side movement and during athletic performance that involves cutting or pivoting.

Ulnar collateral ligament injuries can occur during certain activities such as overhead baseball pitching. Acute or chronic disruption and/or attenuation of the ulnar collateral ligament often result in medial elbow pain, valgus instability, neurologic deficiency, and impaired throwing performance. There are both non-surgical and surgical treatment options.

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.

Follow-up studies by Levy et al. and Stannard at al. both examined failure rates for posterolateral corner repairs and reconstructions. Failure rates repairs were approximately 37 – 41% while reconstructions had a failure rate of 9%.

Other less common surgical complications include deep vein thrombosis (DVTs), infection, blood loss, and nerve/artery damage. The best way to avoid these complications is to preemptively treat them. DVTs are typically treated prophylactically with either aspirin or sequential compression devices (SCDs). In high risk patients there may be a need for prophylactic administration of low molecular weight heparin (LMWH). In addition, having a patient get out of bed and ambulate soon after surgery is a time honored way to prevent DVTs. Infection is typically controlled by administering 1 gram of the antibiotic cefazolin (Ancef) prior to surgery. Excessive blood loss and nerve/artery damage are rare occurrences in surgery and can usually be avoided with proper technique and diligence; however, the patient should be warned of these potential complications, especially in patients with severe injuries and scarring.

Pain along the inside of the elbow is the main symptom of this condition. Throwing athletes report it occurs most often during the acceleration phase of throwing. Closing the hand and clenching the fist has also been shown to reproduce the painful symptoms. The injury is often associated with an experience of a sharp “pop” in the elbow, followed by pain during a single throw. In addition, swelling and bruising of the elbow, loss of elbow range of motion, and a sudden decrease in throwing velocity are all common symptoms of a UCL injury. If the injury is less severe, pain can be minimal with complete rest.

Fractures of the fingers occur when the finger or hands hit a solid object. Fractures are most common at the base of the little finger (boxer's fracture).

Nerve injuries occur as a result of trauma, compression or over-stretching. Nerves send impulses to the brain about sensation and also play an important role in finger movement. When nerves are injured, one can lose ability to move fingers, lose sensation and develop a contracture. Any nerve injury of the hand can be disabling and results in loss of hand function. Thus it is vital to seek medical help as soon as possible after any hand injury.

Sprains result from forcing a joint to perform against its normal range of motion. Finger sprains occur when the ligaments which are attached to the bone are overstretched and this results in pain, swelling, and difficulty for moving the finger. Common examples of a sprain are jammed or twisted fingers. These injuries are common among ball players but can also occur in laborers and handy men. When finger sprains are not treated on time, prolonged disability can result.

An unhappy triad (or terrible triad, "horrible triangle", O'Donoghue's triad or a "blown knee") is an injury to the anterior cruciate ligament, medial collateral ligament, and medial meniscus. Analysis during the 1990s indicated that this 'classic' O'Donoghue triad is actually an unusual clinical entity among athletes with knee injuries. Some authors mistakenly believe that in this type of injury, acute tears of the medial meniscus always present with a concomitant lateral meniscus injury. However, the 1990 analysis showed that lateral meniscus tears are more common than medial meniscus tears in conjunction with sprains of the ACL.

Signs and symptoms include crepitus (a crunching sound made when broken bone ends rub together), pain, tenderness, bruising, and swelling over the fracture site. The fracture may visibly move when the person breathes, and it may be bent or deformed, potentially forming a "step" at the junction of the broken bone ends that is detectable by palpation. Associated injuries such as those to the heart may cause symptoms such as abnormalities seen on electrocardiograms.

The upper and middle parts of the sternum are those most likely to fracture, but most sternal fractures occur below the sternal angle.

Symptoms reported by sufferers include: pain and aching to the neck and back, referred pain to the shoulders, sensory disturbance (such as pins and needles) to the arms and legs, and headaches. Symptoms can appear directly after the injury, but often are not felt until days afterwards. Whiplash is usually confined to the spine. The most common areas of the spine affected by whiplash are the neck and middle of the spine. "Neck" pain is very common between the shoulder and the neck. The "missing link" of whiplash may be towards or inside the shoulder and this would explain why neck therapy alone frequently does not give lasting relief.

Cognitive symptoms following whiplash trauma, such as being easily distracted or irritated, seems to be common and possibly linked to a poorer prognosis.

Tibial plateau fractures typically presents with knee effusion, swelling of the knee soft tissues and inability to bear weight. The knee may be deformed due to displacement and/or fragmentation of the tibia which leads to loss of its normal structural appearance. Blood in the soft tissues and knee joint (hemarthrosis) may lead to bruising and a doughy feel of the knee joint. Due to the tibial plateau's proximity to important vascular (i.e. arteries, veins) and neurological (i.e. nerves such as peroneal and tibial) structures, injuries to these may occur upon fracture. A careful examination of the neurovascular systems is imperative. A serious complication of tibial plateau fractures is compartment syndrome in which swelling causes compression of the nerves and blood vessels inside the leg and may ultimately lead to necrosis or cell death of the leg tissues.

Medial knee injuries are those to the medial side – the inside of the knee – are the most common. The medial ligament complex of the knee is composed of the superficial medial collateral ligament (sMCL), deep medial collateral ligament (dMCL), and the posterior oblique ligament (POL). These ligaments have also been called the medial collateral ligament (MCL), tibial collateral ligament, mid-third capsular ligament, and oblique fibers of the sMCL, respectively. This complex is the major stabilizer of the medial knee. Injuries to the medial side of the knee are most commonly isolated to these ligaments. A thorough understanding of the anatomy and function of the medial knee structures, along with a detailed history and physical exam, are imperative to diagnosing and treating these injuries.

A scapular fracture is a fracture of the scapula, the shoulder blade. The scapula is sturdy and located in a protected place, so it rarely breaks. When it does, it is an indication that the individual was subjected to a considerable amount of force and that severe chest trauma may be present. High-speed vehicle accidents are the most common cause. This could be anywhere from a car accident, motorcycle crash, or high speed bicycle crash but falls and blows to the area can also be responsible for the injury. Signs and symptoms are similar to those of other fractures: they include pain, tenderness, and reduced motion of the affected area although symptoms can take a couple of days to appear. Imaging techniques such as X-ray are used to diagnose scapular fracture, but the injury may not be noticed in part because it is so frequently accompanied by other, severe injuries that demand attention. The injuries that usually accompany scapular fracture generally have the greatest impact on the patient's outcome. However, the injury can also occur by itself; when it does, it does not present a significant threat to life. Treatment involves pain control and immobilizing the affected area, and, later, physical therapy.

The function of the PCL is to prevent the femur from sliding off the anterior edge of the tibia and to prevent the tibia from displacing posterior to the femur. Common causes of PCL injuries are direct blows to the flexed knee, such as the knee hitting the dashboard in a car accident or falling hard on the knee, both instances displacing the tibia posterior to the femur.

The posterior drawer test is one of the tests used by doctors and physiotherapists to detect injury to the PCL.

Surgery to repair the posterior cruciate ligament is controversial due to its placement and technical difficulty.

An additional test of posterior cruciate ligament injury is the "posterior sag test", where, in contrast to the drawer test, no active force is applied. Rather, the person lies supine with the leg held by another person so that the hip is flexed to 90 degrees and the knee 90 degrees. The main parameter in this test is "step-off", which is the shortest distance from the femur to a hypothetical line that tangents the surface of the tibia from the tibial tuberosity and upwards. Normally, the "step-off" is approximately 1 cm, but is decreased (Grade I) or even absent (Grade II) or inverse (Grade III) in injuries to the posterior cruciate ligament.

Patients who are suspected to have a posterior cruciate ligament injury should always be evaluated for other knee injuries that often occur in combination with an PCL injuries. These include cartilage/meniscus injuries, bone bruises, ACL tears, fractures, posterolateral injuries and collateral ligament injuries.

Infrapatellar bursitis is the inflammation of one or both of the infrapatellar bursa, which are located just below the kneecap. Symptoms of bursitis commonly include swelling and knee pain. Bursitis often develops gradually over a period of days to even months but may develop more rapidly, especially in the event of trauma or infection.

Bursitis affecting the superficial infrapatellar bursa is an occupational hazard of persons whose work involves kneeling on hard surfaces. Depending on the occupation affected it is known by a variety of nicknames, most commonly floor layers' knee, but also plumbers' knee, clergyman's knee, or housewife's knee (prepatellar bursitis).

The deep infrapatellar bursa occasionally also become inflamed, swollen, and painful. Bursitis in the deep infrapatellar bursa usually develops from chronic overuse of the knee extensor tendon (patellar tendon) as can occur with repetitive flexing of the knee under pressure in work duties or exercise. Examples might include climbing stairs, jumping, or deep knee bends.

A sternal fracture is a fracture of the sternum (the breastbone), located in the center of the chest. The injury, which occurs in 5–8% of people who experience significant blunt chest trauma, may occur in vehicle accidents, when the still-moving chest strikes a steering wheel or dashboard or is injured by a seatbelt. Cardiopulmonary resuscitation, commonly known as CPR, has also been known to cause thoracic injury, including sternum and rib fractures. Sternal fractures may also occur as a pathological fracture, in people who have weakened bone in their sternum, due to another disease process. Sternal fracture can interfere with breathing by making it more painful; however, its primary significance is that it can indicate the presence of serious associated internal injuries, especially to the heart and lungs.

A tibial plateau fracture is a break of the upper part of the tibia (shinbone) that involves the knee joint. Symptoms include pain, swelling, and a decreased ability to move the knee. People are generally unable to walk. Complication may include injury to the artery or nerve, arthritis, and compartment syndrome.

The cause is typically trauma such as a fall or motor vehicle collision. Risk factors include osteoporosis and certain sports such as skiing. Diagnosis is typically suspected based on symptoms and confirmed with X-rays and a CT scan. Some fractures may not be seen on plain X-rays.

Pain may be managed with NSAIDs, opioids, and splinting. In those who are otherwise healthy, treatment is generally by surgery. Occasionally, if the bones are well aligned and the ligaments of the knee are intact, people may be treated without surgery.

They represent about 1% of broken bones. They occur most commonly in middle aged males and older females. In the 1920s they were called a "fender fracture" due to their association with people being hit by a motor vehicle while walking.
