Avascular necrosis is localised death of the bone. Necrosis can occur due to traumatic injury, side effects of drugs or disease. The dead areas of the bone do not function normally, they weaken and they can collapse. Avascular necrosis eventually leads to the joints attached to the dead bone deteriorating. Avascular necrosis can occur in the knees, shoulder, waist and ankles, but the hip joint is the most commonly affected.

Aortic valve stenosis is a heart condition in which the valve to the biggest artery- the one which provides oxygen-rich blood to our body, called aorta, is narrowed. This prevents the valve from opening fully, obstructing the blood flow from your heart into your body.

When the aortic valve doesn t open, your heart needs to work harder to pump blood to your body making the heart muscle weak. If left undiagnosed aortic stenosis is fatal.

Sometimes children suffer from conditions where their feet may not be in proper shape or size, something that can affect their posture. Most of the times the disorders get corrected themselves as children grow up, but there can be situations where medical attention is required. These conditions can be normal variations in the anatomy as well which don't essentially require treatment. Some of the common orthopedic disorders found in children include:



Flatfeet: While most babies...more

Renal cancer is also known as hypernephroma, renal cell carcinoma (RCC), kidney cancer or renal adenocarcinoma. The kidneys are organs in your body that dispose off waste, while additionally regulating fluid balance. There are small tubes in the kidneys called tubules. These filter the blood, help in discharging waste, and make urine. RCC happens when cancer cells start to grow out of control in the lining of the tubules of the kidney. Renal cancer is a progressive disease that spreads to the lu...more

The hip joint is a ball and socket joint made up of the round head of thigh bone (femoral head) with the cup shaped socket (acetabulum) of the pelvis and Perthe s Disease is an affliction of the hip joints in growing children. It is much more common in boys than girls, and occurs most commonly in children aged between 4 to 10 years. The cause of this problem is still unidentified.

In Perthes disease, changes affect the femoral head which can be seen on X-ray. These changes occur in thre...more

Paget's Disease is a terrible affliction that affects millions of people around the world. It is basically a malformation of bone growth, leading to weakness, easily fractured bones, deformations, and lack of function in joints and bones. This can be caused by two things, either genetics or a slow-developing virus that may be present in the body for many years before actually demonstrating any symptoms.

Paget's disease of bone most commonly occurs in the pelvis, skull, spine and legs. T...more

Renal cell carcinoma is the most common type of kidney cancer and accounts for 90 percent of all kidney cancers. Young children can develop another kind of kidney cancer termed as Wilms tumour. According to a study conducted by the World Health Organization (WHO), 20qw revealed that renal cell carcinoma has increased manifold over the past decade. The primary reason is the improvement of imaging techniques and the lack of healthy lifestyle practices by most adults.

Complications in the heart valve occur when the functioning of the heart valve is impaired. Valves of the heart allow the blood to flow in one direction and prevent the blood from flowing back into the ventricles of the heart.

Heart valve diseases can be classified as follows:

Valvular stenosis: This condition occurs when the valves of the heart does not open completely due to stiffness. As the opening is narrow, the heart has to work hard to pump blood. This condition may lead...more

There are valves in the each of the four chambers of the heart. These valves make sure that blood flows in one direction only. The blood flows from the atria into the ventricles through the mitral and the tricuspid valves. The pulmonic and the aortic valves allow the blood to flow out of the ventricles. Valve problems occur when the normal functioning of the valve is impaired.

Impaired valve function leads to blood flow obstruction, which in turn can lead to stenosis of the valve. This...more

The heart is a wonderfully designed pump that takes care of proper functioning of the body. There are two separate channels, through which pure and impure blood flows through. Blood flow in these two designated networks is one-sided completely and controlled by valves. There are 2 sets of valves as below:

Aortic and pulmonary valves which controls blood flow from the ventricles to the aorta and to the lungs respectively
The mitral and tricuspid valves control blood flow from the atr...more
