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.

A diagnosis can be made using clinical examination, laryngoscope examination, and/or radiographic studies.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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:

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.

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.

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

Imaging diagnosis conventionally begins with plain film radiography. Generally, AP radiographs of the shoulder with the arm in internal rotation offer the best yield while axillary views and AP radiographs with external rotation tend to obscure the defect. However, pain and tenderness in the injured joint make appropriate positioning difficult and in a recent study of plain film x-ray for Hill–Sachs lesions, the sensitivity was only about 20%. i.e. the finding was not visible on plain film x-ray about 80% of the time.

By contrast, studies have shown the value of ultrasonography in diagnosing Hill–Sachs lesions. In a population with recurrent dislocation using findings at surgery as the gold standard, a sensitivity of 96% was demonstrated. In a second study of patients with continuing shoulder instability after trauma, and using double contrast CT as a gold standard, a sensitivity of over 95% was demonstrated for ultrasound. It should be borne in mind that in both those studies, patients were having continuing problems after initial injury, and therefore the presence of a Hill–Sachs lesion was more likely. Nevertheless, ultrasonography, which is noninvasive and free from radiation, offers important advantages.

MRI has also been shown to be highly reliable for the diagnosis of Hill-Sachs (and Bankart) lesions. One study used challenging methodology. First of all, it applied to those patients with a single, or first time, dislocation. Such lesions were likely to be smaller and therefore more difficult to detect. Second, two radiologists, who were blinded to the surgical outcome, reviewed the MRI findings, while two orthopedic surgeons, who were blinded to the MRI findings, reviewed videotapes of the arthroscopic procedures. Coefficiency of agreement was then calculated for the MRI and arthroscopic findings and there was total agreement ( kappa = 1.0) for Hill-Sachs and Bankart lesions.

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.

"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.

Treatment involves pain medication and immobilization at first; later, physical therapy is used. Ice over the affected area may increase comfort. Movement exercises are begun within at least a week of the injury; with these, fractures with little or no displacement heal without problems. Over 90% of scapular fractures are not significantly displaced; therefore, most of these fractures are best managed without surgery. Fractures of the scapular body with displacement may heal with malunion, but even this may not interfere with movement of the affected shoulder. However, displaced fractures in the scapular processes or in the glenoid do interfere with movement in the affected shoulder if they are not realigned properly. Therefore, while most scapular fractures are managed without surgery, surgical reduction is required for fractures in the neck or glenoid; otherwise motion of the shoulder may be impaired.

The decisions involved in the repair of the Hill–Sachs lesion are complex. First, it is not repaired simply because of its existence, but because of its association with continuing symptoms and instability. This may be of greatest importance in the under-25-year-old and in the athlete involved in throwing activities. The Hill-Sachs role in continuing symptoms, in turn, may be related to its size and large lesions, particularly if involving greater than 20% of the articular surface, may impinge on the glenoid fossa (engage), promoting further episodes of instability or even dislocation. Also, it is a fracture, and associated bony lesions or fractures may coexist in the glenoid, such as the so-called bony Bankart lesion. Consequently, its operative treatment may include some form of bony augmentation, such as the Latarjet or similar procedure. Finally, there is no guarantee that associated non-bony lesions, such as a Bankart lesion, SLAP tear, or biceps tendon injury, may not be present and require intervention.

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.

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