Anterior-posterior (AP) and lateral radiographs are typically obtained. In order to rule out other injuries, hip, pelvis, and knee radiographs are also obtained. The hip radiograph is of particular importance, because femoral neck fractures can lead to osteonecrosis of the femoral head.

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.

A bone fracture may be diagnosed based on the history given and the physical examination performed. Radiographic imaging often is performed to confirm the diagnosis. Under certain circumstances, radiographic examination of the nearby joints is indicated in order to exclude dislocations and fracture-dislocations. In situations where projectional radiography alone is insufficient, Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) may be indicated.

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.

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.

When a child experiences a fracture, he or she will have pain and will not be able to easily move the fractured area. A doctor or emergency care should be contacted immediately. In some cases even though the child will not have pain and will still be able to move, medical help must be sought out immediately. To decrease the pain, bleeding, and movement a physician will put a splint on the fractured area. Treatment for a fracture follows a simple rule: the bones have to be aligned correctly and prevented from moving out of place until the bones are healed. The specific treatment applied depends on how severe the fracture is, if it’s an open or closed fracture, and the specific bone involved in the fracture (a hip fracture is treated differently from a forearm fracture for example)

Different treatments for different fractures:

The general treatments for common fractures are as follows:

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.

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.

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.

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.

Anteroposterior (AP) and lateral radiographs the include the entire length of the lower leg (knee to ankle) are highly sensitive and specific for tibial shaft fractures.

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.

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.

Two systems of fracture classification are commonly used to aid diagnosis and management of tibia shaft fractures:

- Oestern and Tscherne Classification

- Gustilo-Anderson Classification

Management is dependent on the determination of whether the fracture is open or closed.

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.

Computed tomography is the most sensitive and specific of the imaging techniques. The facial bones can be visualized as slices through the skeletal in either the axial, coronal or sagittal planes. Images can be reconstructed into a 3-dimensional view, to give a better sense of the displacement of various fragments. 3D reconstruction, however, can mask smaller fractures owing to volume averaging, scatter artifact and surrounding structures simply blocking the view of underlying areas.

Research has shown that panoramic radiography is similar to computed tomography in its diagnostic accuracy for mandible fractures and both are more accurate than plain film radiograph. The indications to use CT for mandible fracture vary by region, but it does not seem to add to diagnosis or treatment planning except for comminuted or avulsive type fractures, although, there is better clinician agreement on the location and absence of fractures with CT compared to panoramic radiography.

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

Children in general are at greater risk because of their high activity levels. Children that have risk-prone behaviors are at even greater risk.

Healing time varies based on age, health, complexity, and location of the break, as well as the bone displacement. For adults, a minimum of 2–6 weeks of sling immobilization is normally employed to allow initial bone and soft tissue healing; teenagers require slightly less, while children can often achieve the same level in two weeks. During this period, patients may remove the sling to practice passive pendulum range of motion exercises to reduce atrophy in the elbow and shoulder, but they are minimized to 15–20° off vertical. Depending on the severity of fracture, a person can begin to use the arm if comfortable with movement and no pain results. The final goal is to be able to have full range of motion with no pain; therefore, if any pain occurs, allowing for more recovery time is best. Depending on severity of the fracture, athletes involved in contact sports may need a longer period of rest to heal to avoid refracturing bone. A person should be able to return unrestricted to any sports or work by 3 months after the injury.

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.

X-rays of the chest are taken in people with chest trauma and symptoms of sternal fractures, and these may be followed by CT scanning. Since X-rays taken from the front may miss the injury, they are taken from the side as well.

Management involves treating associated injuries; people with sternal fractures but no other injuries do not need to be hospitalized. However, because it is common for cardiac injuries to accompany sternal fracture, heart function is monitored with electrocardiogram. Fractures that are very painful or extremely out of place can be operated on to fix the bone fragments into place, but in most cases treatment consists mainly of reducing pain and limiting movement. The fracture may interfere with breathing, requiring tracheal intubation and mechanical ventilation.

Patients who have experienced a pathologic fracture will be investigated for the cause of the underlying disease, if it is unknown. Treatment of any underlying disease, such as chemotherapy if indicated for bone cancer, may help to improve the pain of a sternal fracture.

A 2015 Cochrane review found that available evidence for treatment options of distal femur fractures is insufficient to inform clinical practice and that there is a priority for a high-quality trial to be undertaken. Open fractures must undergo urgent surgery to clean and repair them, but closed fractures can be maintained until the patient is stable and ready for surgery.

A Cochrane review of low-intensity pulsed ultrasound to speed healing in newly broken bones found insufficient evidence to justify routine use. Other reviews have found tentative evidence of benefit. It may be an alternative to surgery for established nonunions.

Vitamin D supplements combined with additional calcium marginally reduces the risk of hip fractures and other types of fracture in older adults; however, vitamin D supplementation alone did not reduce the risk of fractures.

There are various classification systems of mandibular fractures in use.
