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.

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.

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

X-rays usually do not show evidence of new stress fractures, but can be used 3 weeks after onset of pain when the bone begins to remodel. A CT scan, MRI, or 3-phase bone scan may be more effective for early diagnosis.

MRI appears to be the most accurate test.

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.

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.

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.

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.

The diagnosis is a combination of clinical suspicion plus radiological investigation. Children with a SCFE experience a decrease in their range of motion, and are often unable to complete hip flexion or fully rotate the hip inward. 20-50% of SCFE are missed or misdiagnosed on their first presentation to a medical facility. SCFEs may be initially overlooked, because the first symptom is knee pain, referred from the hip. The knee is investigated and found to be normal.

The diagnosis requires x-rays of the pelvis, with anteriorposterior (AP) and frog-leg lateral views. The appearance of the head of the femur in relation to the shaft likens that of a "melting ice cream cone", visible with Klein's line. The severity of the disease can be measured using the Southwick angle.

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.

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.

Because of the high rate of associated ligamentous and meniscal injury, the presence of a Segond or reverse Segond fracture requires that these other pathologies must be specifically ruled out. Increasingly, reconstruction of the ACL is combined with reconstruction of the ALL when this associated pathology is present. It is often associated with an increased 'pivot shift' on physical exam.

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.

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.

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:

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.

"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 is aimed at achieving a stable, aligned, mobile and painless joint and to minimize the risk of post-traumatic osteoarthritis. To achieve this operative or non-operative treatment plans are considered by physicians based on criteria such as patient characteristics, severity, risk of complications, fracture depression and displacement, degree of injury to ligaments and menisci, vascular and neurological compromise.

For early management, traction should be performed early in ward. It can either be Skin Traction or Skeletal Traction. Depends on the body weight of patient and stability of the joint. Schantz pin insertion over the Calcaneum should be done from Medial to lateral side.

Later when condition is stable. Definitive plan would be Buttress Plating and Lag Screw fixation.

The first line treatment should be reduction of movements for 6 to 12 weeks. Wooden-soled shoes or a cast should be given for this purpose. In rare cases in which stress fracture occurs with a cavus foot, plantar fascia release may be appropriate.

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

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

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.

Shin splints can be diagnosed by a physician after taking a thorough history and performing a complete physical examination. The physical examination uses gentle pressure to determine whether there is tenderness over a 4–6 inch section on the lower, inside shin area. The pain has been described as a dull ache to an intense pain that increases during exercise, and some individuals experience swelling in the pain area. People who have previously had shin splints are more likely to have it again.

Vascular and neurological examinations produce normal results in patients with shin splints. Radiographies and three-phase bone scans are recommended to differentiate between shin splints and other causes of chronic leg pain. Bone scintigraphy and MRI scans can be used to differentiate between stress fractures and shin splints.

It is important to differentiate between different lower leg pain injuries, including shin splints, stress fractures, compartment syndrome, nerve entrapment, and popliteal artery entrapment syndrome. These conditions often have many overlapping symptoms which makes a final diagnosis difficult, and correct diagnosis is needed to determine the most appropriate treatment.

If shin splints are not treated properly, or if exercise is resumed too early or aggressively, shin splints can become permanent.
