X-ray of the affected wrist is required if a fracture is suspected. Anteroposterior (AP), lateral, and oblique views can be used together to describe the fracture. X-ray of the uninjured wrist should also be taken to determine if there are any normal anatomic variations. Investigation of a potential distal radial fracture includes assessment of the angle of the joint surface on lateral X-ray (volar/dorsal tilt), the loss of length of the radius from the collapse of the fracture (radial length), and congruency of the distal radioulnar joint (DRUJ). Displacement of the articular surface is the most important factor affecting prognosis and treatment. CT scan is often performed to further investigate the articular anatomy of the fracture, especially if surgery is considered. MRI can be considered to evaluate for soft tissue injuries, including damage to the TFCC and the interosseous ligaments.

Diagnosis may be evident clinically when the distal radius is deformed but should be confirmed by X-ray.

The differential diagnosis includes scaphoid fractures and wrist dislocations, which can also co-exist with a distal radius fracture. Occasionally, fractures may not be seen on X-rays immediately after the injury. Delayed X-rays, X-ray computed tomography (CT scan), or Magnetic resonance imaging (MRI) will confirm the diagnosis.

To assess an olecranon fracture, a careful skin exam is performed to ensure there is no open fracture. Then a complete neurological exam of the upper limb should be documented. Frontal and lateral X-ray views of the elbow are typically done to investigate the possibility of an olecranon fracture. A true lateral x-ray is essential to determine the fracture pattern, degree of displacement, comminution, and the degree of articular involvement.

X-ray is seldom helpful, but a CT scan and an MRI study may help in diagnosis.

Bone scans are positive early on. Dual energy X-ray absorptiometry is also helpful to rule out comorbid osteoporosis.

Typically, radiographs are taken of the hip from the front (AP view), and side (lateral view). Frog leg views are to be avoided, as they may cause severe pain and further displace the fracture. In situations where a hip fracture is suspected but not obvious on x-ray, an MRI is the next test of choice. If an MRI is not available or the patient can not be placed into the scanner a CT may be used as a substitute. MRI sensitivity for radiographically occult fracture is greater than CT. Bone scan is another useful alternative however substantial drawbacks include decreased sensitivity, early false negative results, and decreased conspicuity of findings due to age related metabolic changes in the elderly.

As the patients most often require an operation, full pre-operative general investigation is required. This would normally include blood tests, ECG and chest x-ray.

Diagnosis is based on symptom and confirmed with X-rays. In children an MRI may be required.

Diagnosis by a doctor’s examination is the most common, often confirmed by x-rays. X-ray is used to display the fracture and the angulations of the fracture. A CT scan may be done in very rare cases to provide a more detailed picture.

X-rays of the affected hip usually make the diagnosis obvious; AP (anteroposterior) and lateral views should be obtained.

Trochanteric fractures are subdivided into either intertrochanteric (between the greater and lesser trochanter) or pertrochanteric (through the trochanters) by the Müller AO Classification of fractures. Practically, the difference between these types is minor. The terms are often used synonymously. An "isolated trochanteric fracture" involves one of the trochanters without going through the anatomical axis of the femur, and may occur in young individuals due to forceful muscle contraction. Yet, an "isolated trochanteric fracture" may not be regarded as a true hip fracture because it is not cross-sectional.

In all injuries to the tibial plateau radiographs (commonly called x-rays) are imperative. Computed tomography scans are not always necessary but are sometimes critical for evaluating degree of fracture and determining a treatment plan that would not be possible with plain radiographs. Magnetic Resonance images are the diagnositic modality of choice when meniscal, ligamentous and soft tissue injuries are suspected. CT angiography should be considered if there is alteration of the distal pulses or concern about arterial injury.

The indication to surgically stabilize a cervical fracture can be estimated from the "Subaxial Injury Classification" (SLIC). In this system, a score of 3 or less indicates that conservative management is appropriate, a score of 5 or more indicates that surgery is needed, and a score of 4 is equivocal. The score is the sum from 3 different categories: morphology, discs and ligaments, and neurology:

Conventional radiography is usually the initial assessment tool when a calcaneal fracture is suspected. Recommended x-ray views are (a) axial, (b) anteroposterior, (c) oblique and (d) views with dorsiflexion and internal rotation of the foot. However, conventional radiography is limited for visualization of calcaneal anatomy, especially at the subtalar joint. A CT scan is currently the imaging study of choice for evaluating calcaneal injury and has substituted conventional radiography in the classification of calcaneal fractures. Axial and coronal views are obtained for proper visualization of the calcaneus, subtalar, calcaneocuboid and talonavicular joints.

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.

Diagnosis is confirmed by x-ray imaging. Displaced fractures are readily apparent. A non-displaced fracture can be difficult to identify and a fracture line may not be visible on the X-rays. However, the presence of a joint effusion is highly suggestive of a non-displaced fracture. Bleeding from the fracture expands the joint capsule and is visualized on the lateral view as a darker area anteriorly and posteriorly, and is known as the sail sign. Depending on the child's age, parts of the bone will still be developing and if not yet calcified, will not show up on the X-rays. At times, X-rays of the opposite elbow may be obtained for comparison. There are landmarks on the X-rays that can be used to assess displacement, including the "anterior humeral line", which is a line drawn down along the front of the humerus on the lateral view and it should pass through the middle third of the capitulum of the humerus.

The basic method to check for a clavicle fracture is by an X-ray of the clavicle to determine the fracture type and extent of injury. In former times, X-rays were taken of both clavicle bones for comparison purposes. Due to the curved shape in a tilted plane X-rays are typically oriented with ~15° upwards facing tilt from the front. In more severe cases, a computerized tomography (CT) or magnetic resonance imaging (MRI) scan is taken.

However, the standard method of diagnosis through ultrasound imaging performed in the emergency room may be equally accurate in children.

Segond and reverse Segond fractures are characterized by a small avulsion, or "chip", fragment of characteristic size that is best seen on plain radiography in the anterior-posterior plane. The chip of bone may be very difficult to see on the plain x-ray exam, and may be better seen on computed tomography. MRI may be useful for visualization of the associated bone marrow edema of the underlying tibial plateau on fat- saturated T2W and STIR images, as well as the associated findings of ligamentous and/or meniscal injury.

Pelvic fractures can be dangerous to one’s physical health. As the human body ages, the bones become more weak and brittle and are therefore more susceptible to fractures. Certain precautions are crucial in order to lower the risk of getting pelvic fractures. The most damaging is one from a car accident, cycling accident, or falling from a high building which can result in a high energy injury. This can be very dangerous because the pelvis supports many internal organs and can damage these organs. Falling is one of the most common causes of a pelvic fracture. Therefore, proper precautions should be taken to prevent this from happening.

Severe pain will usually be present at the point of injury. Pressure on a nerve may also cause pain from the neck down the shoulders and/or arms. Bruising and swelling may be present at the back of the neck. A neurological exam will be performed to assess for spinal cord injury. X-rays will be ordered to determine the severity and location of the fracture. CT (computed tomography) scans may be ordered to assess for gross abnormalities not visible by regular X-ray. MRI (magnetic resonance imaging) tests may be ordered to provide high resolution images of soft tissue and determine whether there has been damage to the spinal cord, although such damage is usually obvious in the conscious patient because of the immediate functional consequences of numbness and paralysis in much of the body.

It is also common for imaging (either a plain film X-ray or CT scan) to be completed when assessing a cervical injury. This is the most common way to diagnose the location and severity of the fracture. To decrease the use C-spine scans yielding negative findings for fracture, thus unnecessarily exposing people to radiation and increase time in the hospital and cost of the visit, multiple clinical decision support rules have been developed to help clinicians weigh the option to scan a patient with a neck injury. Among these are the Canadian C-spine rule and the NEXUS criteria for C-Spine imaging, which both help make these decisions from easily obtained information. Both rules are widely used in emergency departments and by paramedics.

Definitive diagnosis of humerus fractures is typically made through radiographic imaging. For proximal fractures, X-rays can be taken from a scapular anteroposterior (AP) view, which takes an image of the front of the shoulder region from an angle, a scapular Y view, which takes an image of the back of the shoulder region from an angle, and an axillar lateral view, which has the patient lie on his or her back, lift the bottom half of the arm up to the side, and have an image taken of the axilla region underneath the shoulder. Fractures of the humerus shaft are usually correctly identified with radiographic images taken from the AP and lateral viewpoints. Damage to the radial nerve from a shaft fracture can be identified by an inability to bend the hand backwards or by decreased sensation in the back of the hand. Images of the distal region are often of poor quality due to the patient being unable to extend the elbow because of pain. If a severe distal fracture is supected, then a computed tomography (CT) scan can provide greater detail of the fracture. Nondisplaced distal fractures may not be directly visible; they may only be visible due to fat being displaced because of internal bleeding in the elbow.

"Baumann's angle", also known as the humeral-capitellar angle, is measured on an AP radiograph of the elbow between the long axis of the humerus and the growth plate of the lateral condyle.

Reported normal values for Baumann's angle range between 9 and 26° An angle of more than 10° is generally regarded as acceptable. When reducing paediatric supracondylar humerus fractures, a deviation of more than 5° from the contralateral side should not be accepted.

Alteration of Baumann angle: Baumann's angle is created by drawing a line parallel to the longitudinal axis of the humeral shaft and a line along the lateral condylar physis as viewed on the AP image normal is 70-75 degrees, but best judge is a comparison of the contralateral side deviation of more than 5 degrees indicates coronal plane deformity and should not be accepted.

There are several classification schemes for ankle fractures:

- The Lauge-Hansen classification categorises fractures based on the mechanism of the injury as it relates to the position of the foot and the deforming force (most common type is supination-external rotation)

- The Danis-Weber classification categorises ankle fractures by the level of the fracture of the distal fibula (type A = below the syndesmotic ligament, type B = at its level, type C = above the ligament), with use in assessing injury to the syndesmosis and the interosseous membrane

- The Herscovici classification categorises medial malleolus fractures of the distal tibia based on level.

- The Ruedi-Allgower classification categorizes pilon fractures of the distal tibia.

Most fractures of the scapula can be seen on a chest X-ray; however, they may be missed during examination of the film. Serious associated injuries may distract from the scapular injury, and diagnosis is often delayed. Computed tomography may also be used. Scapular fractures can be detected in the standard chest and shoulder radiographs that are given to patients who have suffered significant physical trauma, but much of the scapula is hidden by the ribs on standard chest X-rays. Therefore, if scapular injury is suspected, more specific images of the scapular area can be taken.

Evaluating soft-tissue involvement is the most important aspect of the clinical examination because of its association with patient outcome. Skin blisters may become infected if medical attention is delayed, which can lead to necrotizing fasciitis or osteomyelitis, causing permanent damage to muscle or bone. Ligament and tendon involvement should also be explored. Achilles tendon injury can be seen with posterior (Type C) fractures. Since calcaneal fractures are related to falls from height, other concomitant injuries should be evaluated. Vertebral compression fractures occur in approximately 10% of these patients. A trauma-focused clinical approach should be implemented; tibial, knee, femur, hip, and head injuries should be ruled out by means of history and physical exam.

Fractures of the humerus are classified based on the location of the fracture and then by the type of fracture. There are three locations that humerus fractures occur: at the proximal location, which is the top of the humerus near the shoulder, in the middle, which is at the shaft of the humerus, and the distal location, which is the bottom of the humerus near the elbow. Proximal fractures are classified into one of four types of fractures based on the displacement of the greater tubercle, the lesser tubercle, the surgical neck, and the anatomical neck, which are the four parts of the proximal humerus, with fracture displacement being defined as at least one centimeter of separation or an angulation greater than 45 degrees. One-part fractures involve no displacement of any parts of the humerus, two-part fractures have one part displaced relative to the other three; three-part fractures have two displaced fragments, and four-part fractures have all fragments displaced from each other. Fractures of the humerus shaft are subdivided into transverse fractures, spiral fractures, "butterfly" fractures, which are a combination of transverse and spiral fractures, and pathological fractures, which are fractures caused by medical conditions. Distal fractures are split between supracondylar fractures, which are transverse fractures above the two condyles at the bottom of the humerus, and intercondylar fractures, which involve a T- or Y-shaped fracture that splits the condyles.

Treatment may be with or without surgery, depending on the type of fracture.

Nasal fractures are usually identified visually and through physical examination. Medical imaging is generally not recommended. A priority is to distinguish simple fractures limited to the nasal bones (Type 1) from fractures that also involve other facial bones and/or the nasal septum (Types 2 and 3). In simple Type 1 fractures X-Rays supply surprisingly little information beyond clinical examination. However, diagnosis may be confirmed with X-rays or CT scans, and these are required if other facial injuries are suspected.

A fracture that runs horizontally across the septum is sometimes called a "Jarjavay fracture", and a vertical one, a "Chevallet fracture".

Although treatment of an uncomplicated fracture of nasal bones is not urgent—a referral for specific treatment in five to seven days usually suffices—an associated injury, nasal septal hematoma, occurs in about 5% of cases and does require urgent treatment and should be looked for during the assessment of nasal injuries.
