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.

Injuries in rock climbing may occur due to falls, or due to overuse (see Sports injury). Injuries due to falls are relatively uncommon; the vast majority of injuries result from overuse, most often occurring in the fingers, elbows, and shoulders. Such injuries are often no worse than torn calluses, cuts, burns and bruises. However, overuse symptoms, if ignored, may lead to permanent damage (esp. to tendons, tendon sheaths, ligaments, and joint capsules).

The climbers most prone to injuries are intermediate to expert within lead climbing or bouldering.

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.

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.

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.

People usually present with a history of an injury and localized pain. There is often a deformity in the wrist with associated swelling. Numbness of the hand can occur because of compression on the median nerve across the wrist (carpal tunnel syndrome). The wrist deformity often limits motion of the fingers.

Swelling, deformity, tenderness and loss of wrist motion are normal features on examination of a person with a distal radius fracture. Examination should rule out a skin wound which might suggest an open fracture. It is imperative to check for loss of sensation, loss of circulation to the hand, and more proximal injuries to the forearm, elbow and shoulder. The most common associated neurological finding is decreased sensation over the thenar eminence due to associated median nerve injury.

A classic "dinner fork" deformity may be seen in dorsally angulated fractures due to dorsal displacement of the carpus. The reverse deformity may be seen in volarly angulated fractures.

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.

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.

Symptoms include:

- The child stops using the arm, which is held in extension (or slightly bent) and palm down.

- Minimal swelling.

- All movements are permitted except supination.

- Caused by longitudinal traction with the wrist in pronation, although in a series only 51% of people were reported to have this mechanism, with 22% reporting falls, and patients less than 6 months of age noted to have the injury after rolling over in bed.

Pain and soft-tissue swelling are present at the distal-third radial fracture site and at the wrist joint. This injury is confirmed on radiographic evaluation. Forearm trauma may be associated with compartment syndrome. Anterior interosseous nerve (AIN) palsy may also be present, but it is easily missed because there is no sensory component to this finding. A purely motor nerve, the AIN is a division of the median nerve. Injury to the AIN can cause paralysis of the flexor pollicis longus and flexor digitorum profundus muscles to the index finger, resulting in loss of the pinch mechanism between the thumb and index finger. Galeazzi fractures are sometimes associated with wrist drop due to injury to radial nerve, extensor tendons or muscles.

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.

The injury can be difficult to diagnose initially as the attention is focused on the injury to the radial head, leading to the distal radio-ulnar injury being overlooked. The examination finding of tenderness of the distal radio-ulnar joint suggests an Essex-Lopresti injury in patients who have sustained high energy forearm trauma. Plain radiography shows the radial head fracture, with dorsal subluxation of the ulna often seen on lateral view of the pronated wrist.

Tennis elbow or lateral epicondylitis is a condition in which the outer part of the elbow becomes sore and tender at the lateral epicondyle. The forearm muscles and tendons become damaged from repetitive overuse. This leads to pain and tenderness on the outside of the elbow.

Any activity, including playing tennis, that involves repetitive use of the extensor muscles of the forearm can cause acute or chronic tendonitis of the tendinous insertion of these muscles at the lateral epicondyle of the elbow. The condition is common in carpenters and laborers who swing a hammer or other tool with the forearm, and is similar to golfer's elbow, which affects the medial epicondyle on the inside of the elbow. Continuing activity after onset of the condition and avoiding mandatory rest may lead to permanent onset of pain and only treatable via surgery.

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.

The Hume fracture is an injury of the elbow comprising a fracture of the olecranon with an associated anterior dislocation of the radial head which occurs in children. It was originally described as an undisplaced olecranon fracture, but more recently includes displaced fractures and can be considered a variant of the Monteggia fracture.

The injury was described in 1957 by A.C. Hume of the orthopaedic surgery department of St. Bartholomew's Hospital, Rochester.

The term "Colles fracture" is classically used to describe a fracture at the distal end of the radius, at its cortico-cancellous junction. However, now the term tends to be used loosely to describe any fracture of the distal radius, with or without involvement of the ulna, that has dorsal displacement of the fracture fragments. Colles himself described it as a fracture that “takes place at about an inch and a half (38mm) above the carpal extremity of the radius” and “the carpus and the base of metacarpus appears to be thrown backward”. The fracture is sometimes referred to as a "dinner fork" or "bayonet" deformity due to the shape of the resultant forearm.

Colles' fractures can be categorized according to several systems including Frykman, Gartland & Werley, Lidström, Nissen-Lie and the Older's classifications.

Supracondylar humerus fractures typically result from a fall on to an outstretched arm, usually leading to a forced hyperextension of the elbow. Typically, this is an isolated injury to the elbow (no injuries elsewhere). Children with this injury present with pain and swelling about the elbow. Motion at the elbow and at the wrist make the pain worse. With mild or moderate fracture displacement, there may be deformity at the elbow.

Golfer's elbow, or medial epicondylitis, is tendinosis of the medial epicondyle on the inside of the elbow. It is in some ways similar to tennis elbow, which affects the outside at the lateral epicondyle.

The anterior forearm contains several muscles that are involved with flexing the digits of the hand, and flexing and pronating the wrist. The tendons of these muscles come together in a common tendinous sheath, which originates from the medial epicondyle of the humerus at the elbow joint. In response to minor injury, or sometimes for no obvious reason at all, this point of insertion becomes inflamed.

Symptoms associated with tennis elbow include, but are not limited to: radiating pain from the outside of the elbow to the forearm and wrist, pain during extension of wrist, weakness of the forearm, a painful grip while shaking hands or torquing a doorknob, and not being able to hold relatively heavy items in the hand. The pain is similar to the condition known as "golfer's elbow", but the latter occurs at the medial side of the elbow.

The Essex-Lopresti fracture is a fracture of the radial head with concomitant dislocation of the distal radio-ulnar joint and disruption of the interosseous membrane. The injury is named after Peter Essex-Lopresti who described it in 1951.

The Jersey Finger is a finger-related tendon injury that is common in athletics and can result in permanent loss of flexion of the end of the finger if not surgically repaired.

This injury often occurs in American football when a player grabs another player's jersey with the tips of one or more fingers while that player is pulling or running away.

A "Jersey finger" is an injury to an FDP tendon at its point of attachment to the distal phalanx. This injury often occurs in American football when a player grabs another player's jersey with the tips of one or more fingers while that player is pulling or running away. The force of this action hyperextends the tip of the finger at the DIP joint while the proximal portion of the finger is flexed. This action can partially or completely rupture the FDP tendon at or near its attachment point on the distal phalanx. Sometimes, the force is great enough to pull off or avulse a piece of phalangeal bone to which the tendon can remain attached. Although it is a common football injury, this injury can occur during other sports or activities as well.

After the injury occurs, the torn FDP tendon may retract slightly, remaining in the finger near the PIP joint, or can retract more fully into the palm of the hand. A person who suffers a jersey finger injury in which the FDP tendon is completely ruptured cannot flex the affected digit at the DIP joint without assistance.

Signs and Symptoms include:

- A pop or rip felt in the finger at the time of the injury

- Pain when moving the injured finger and the inability to bend the DIPjoint

- Tenderness, swelling. and warmth of the injured finger

- Bruising after 48 hours

- Occasionally a lump felt in the palm of the finger

- Mallet finger deformity

A pulled elbow, also known as a radial head subluxation, is when the ligament that wraps around the radial head slips off. Often a child will hold their arm against their body with the elbow slightly bent. They will not move the arm as this results in pain. Touching the arm, without moving the elbow, is usually not painful.

A pulled elbow typically results from a sudden pull on an extended arm. This may occur when lifting or swinging a child by the arms. The underlying mechanism involves slippage of the annular ligament off of the head of the radius followed by the ligament getting stuck between the radius and humerus. Diagnosis is often based on symptoms. Xrays may be done to rule out other problems.

Prevention is by avoiding potential causes. Treatment is by reduction. Moving the forearm into a palms down position with straitening at the elbow appears to be more effect than moving it into a palms up position followed by bending at the elbow. Following a successful reduction the child should return to normal within a few minutes. A pulled elbow is common. It generally occurs in children between the ages of 1 and 4 years old, though it can happen up to 7 years old.
