Colles' Fracture

Causes

The fracture is most commonly caused by people falling backward onto a hard surface and breaking their fall with extended outstretched hands.

Displacements

1. Proximal impaction
2. Dorsal displacement
3. Dorsal tilt
4. Ulnar tilt

Treatment

Treatment of depends on the severity of the fracture. An undisplaced fracture may be treated with a cast alone.The cast is applied with the distal fragment in palmar flexion and ulnar deviation. A fracture with mild angulation and displacement may require closed reduction. Significant angulation and deformity may require an open reduction and internal fixation or external fixation.

Myositis Ossificans

Types:

• Nonhereditary Myositis Ossificans


• Myositis Ossificans Progressiva

Clinical Features:

Myositis ossificans usually presents with pain, tenderness, focal swelling, and joint muscle reduction, in the aftermath of a painful muscle contusion which resolved more slowly than expected, if at all.
The condition rarely is asymptomatic, and may sometimes be diagnosed from radiographs obtained for unrelated problems.
Most (i.e. 80%) ossifications arise in the thigh or arm, and are caused by a premature return to activity after an injury. Other sites include intercostal spaces, erector spinae, pectoralis muscles, glutei, and the chest. Hazy densities are sometimes noted ca. one month after injury, while the denser opacities eventually seen may not be apparent until two months have passed

Treatment:

Treatment is initially conservative, as some patients' calcifications will spontaneously be reabsorbed, and others will have minimal symptoms. In occasional cases, surgical debridement of the abnormal tissue is required, although success of such therapy is limited.

Paget's disease of Bone

Paget's disease, otherwise known as osteitis deformans, is a chronic disorder that typically results in enlarged and deformed bones. It is named after Sir James Paget, the British surgeon who first described this disease. The excessive breakdown and formation of bone tissue that occurs with Paget's disease can cause bone to weaken, resulting in bone pain, arthritis, deformities, and fractures. Paget's disease may be caused by a slow virus infection (i.e., paramyxoviruses such as measles and respiratory syncytial virus), present for many years before symptoms appear. There is also a hereditary factor since the disease may appear in more than one family member.
Paget's disease is rarely diagnosed in people less than 40 years of age. Men are more commonly affected than women. Prevalence of Paget's disease ranges from 1.5 to 8 percent depending on age and country of residence. Prevalence of familial Paget's disease ranges from 10 to 40 percent in different parts of the world. Because early diagnosis and treatment is important, after age 40, siblings and children of someone with Paget's disease may wish to have an alkaline phosphatase blood test every 2 or 3 years. If the alkaline phosphatase level is above normal, other tests such as a bone-specific alkaline phosphatase test, bone scan, or x-ray can be performed.

Acute Myocardial Infarction

Acute myocardial infarction (AMI or MI), more commonly known as a heart attack, is a medical condition that occurs when the blood supply to a part of the heart is interrupted, most commonly due to rupture of a vulnerable plaque. The resulting ischemia or oxygen shortage causes damage and potential death of heart tissue. It is a medical emergency, and the leading cause of death for both men and women all over the world.

Important risk factors are a previous history of vascular disease such as atherosclerotic coronary heart disease and/or angina, a previous heart attack or stroke, any previous episodes of abnormal heart rhythms or syncope, older age—especially men over 40 and women over 50, smoking, excessive alcohol consumption, the abuse of certain drugs, high triglyceride levels, high LDL ("Low-density lipoprotein") and low HDL ("High density lipoprotein"), diabetes, high blood pressure, obesity, and chronically high levels of stress in certain persons.

The term myocardial infarction is derived from myocardium (the heart muscle) and infarction (tissue death due to oxygen starvation). The phrase "heart attack" is sometimes used incorrectly to describe sudden cardiac death, which may or may not be the result of acute myocardial infarction.

Classical symptoms of acute myocardial infarction include chest pain (typically radiating to the left arm), shortness of breath, nausea, vomiting, palpitations, sweating, and anxiety. Patients frequently feel suddenly ill. Women often experience different symptoms from men. The most common symptoms of MI in women include shortness of breath, weakness, and fatigue. Approximately one third of all myocardial infarctions are silent, without chest pain or other symptoms.

Immediate treatment for suspected acute myocardial infarction includes oxygen, aspirin, glyceryl trinitrate and pain relief, usually morphine sulfate. The patient will receive a number of diagnostic tests, such as an electrocardiogram (ECG, EKG), a chest X-ray and blood tests to detect elevated creatine kinase or troponin levels (these are chemical markers released by damaged tissues, especially the myocardium). Further treatment may include either medications to break down blood clots that block the blood flow to the heart, or mechanically restoring the flow by dilatation or bypass surgery of the blocked coronary artery. Coronary care unit admission allows rapid and safe treatment of complications such as abnormal heart rhythms.
