A fracture separates a single solid object into two or more pieces due to pressure. In medical terms, a fracture refers to a broken bone due to some kind of external trauma. A crack in the bone, on the other hand, it does not cause a clean break in the bone, there is only a separation or discontinuity in the bone material.

A crack in the bone caused due to repeated stress is often called as 'hairline fracture'. Here are the basic differences between a crack and a fracture in the bone and how to treat them:

1. A crack or hairline fracture is rarely caused by a single injury. It is usually the result of bone fatigue, which may be caused due to repeated, concentrated stress over a long period of time and thus, it is also called as 'stress fracture'. Other bone fractures are almost always the result of sudden and severe force on the bones.

2. The skeletal system constantly remodels itself. The cells, known as 'osteoblasts' absorb calcium and secrete bone connective tissue. If a particular site is exposed to recurrent bouts of force (which are individually not impactful enough to cause a crack), over time the osteoblasts in that region malfunction and the crack appears.

Muscular exhaustion can also cause cracks in the bone. Fractures are caused due to sudden external single force trauma to the bone. Nutritional problems like deficiencies of Calcium, Phosphorus, vitamin D and excessive smoking decrease the bone mineral density and increase the chance of both cracks and fractures.

3. Symptoms of a crack are swelling, tenderness and sharp pain in the injured region and the symptoms worsen over time. A fracture has similar symptoms and might also exhibit an external physical distortion and makes it impossible to move that part of the body that where the bone is broken.

4. An MRI is often suggested for detecting the crack or crack-prone areas because an X-ray can only detect the crack after it widens somewhat or the bone starts paining because the rays cannot pass through the tiny gap in bone material. A fracture is easily detectable by an X-ray because the rays pass right through the break.

5. Complete rest for six to eight weeks is the most effective way of healing a crack. Using a walking boot in case of cracks in the leg bones in also helpful. Healing fractures require extensive medical intervention. Surgical techniques like bone grafting and the insertion of metal plates are used to reposition the broken bone.

Cracks VS Fractures

Stress fractures are small cracks that may appear in a bone. It occurs due to repetitive application of force in the same area. It is very common among various sports such as running, tennis and football. It may also occur due to osteoporosis as this disorder weakens the bones and allows stress fractures to occur easily.


The majority of stress fractures occur due to overuse of a specific muscle. The bones and the muscles used in a specific movement do not get time to recover, thus leading to stress fracture.


Causes
The major cause of stress fracture is change in physical activity, such as a sudden increase in exercise. The other factors that may lead to stress fracture are -


1. Poor conditioning: if you are starting an exercise regimen without proper preparation, then it may cause stress on the muscles. It is important that you condition your body before doing any intense activity to prevent injuries.


2. Bone insufficiency: various disorders such as osteoporosis reduces bone strength and increases the likelihood of a stress fracture. If you have low bone density then you are at a higher risk of having stress fractures.


3. Change in surface: change in surface like shifting from running on grass to road tends to cause more stress on the legs, thus increasing the likelihood of a fracture.


4. Improper form: performing any exercise with improper form may lead to a number of injuries. It is recommended to learn the correct technique before exercising, so you may use a spotter or a trainer to guide you.


Symptoms
The symptoms of a stress fracture are: 


1. Pain: you may experience dull to severe pain if you have stress fractures. The severity of pain will depend on the severity of the fracture.


2. Swelling: pain may be accompanied by swelling on the sides and the top of the foot.


3. Tenderness: stress fractures may cause tenderness in the muscles around the affected area.

Causes and Symptoms of Stress Fracture

Broken bone is commonly known as bone fracture a d it occurs when an exorbitant amount of force is applied causing the bone to split or shatter. While some minor fractures lead to cracks and crannies, others may lead to complete breakage of the bones. Despite being hard, bones are formed in such a way that they can absorb pressure to only a certain extent, beyond which they break. Statistically, the incidence of broken bones are most common in children and in old age people.

Causes of Bone Fracture
Bone fracture can be caused due to a number of reasons; both intentional and accidental. Some of them include:
1. Accidents and injuries: Sports injuries, being hit by a car and tripping and falling are some of the typical episodes.
2. Old age: Diseases such as osteoporosis and brittle bone disease are common in aged people. As bones tend to become more fragile among the aged, they are at a greater chance of bone fractures.

Type of bone fractures
Primarily bone fractures are of four types, based on the way the bone splits. They are:

Complete fracture: This type of fracture refers to a complete breakage of the bone wherein the fracture may occur at various parts of the bone.
Incomplete fracture: In this type of fracture, the bone partially breaks instead of splitting entirely.
Compound fractures: This is a type of a fracture wherein the bone breaks past the skin. It is also known as an open fracture.
Simple fracture: In this type of a fracture, the bone breaks without causing an open wound on the skin.
Treatment of bone fractures
In case of a broken bone, the immediate course of action would be to reach for the first aid box. This can be done to stabilize the bone prior to hospitalization. Icing the injury, elevating the injured area to prevent further swelling and covering the wound with bandages are common measures. In many cases, people also make household splints (made of newspapers) to keep the bone stabilized. Hospitalization and especially surgery, can be also opted for in case of severe fractures.

Bone Fracture - Understanding the Types + Causes

The medical term used to describe a broken wrist is wrist fracture. The fracture might be in the 10 bones, which make up the wrist or in the radius. Some fractures can be serious while others may be tiny. The serious fractures make the bone unstable and these might require surgeries to cure. Open fracture is when the bone breaks and it breaks through the skin. This might cause an infection to the wounded area.

Causes
The most basic cause of a wrist fracture is injury. Any fall on your outstretched hand and you might have to nurse a fractured wrist. This type of fracture is common among sportsmen. If you are suffering from osteoporosis, then you have a high risk of getting a wrist fracture. Traumatic accidents may also cause severe wrist fractures.

Symptoms
The symptoms of a wrist fracture can be extremely painful. The pain escalates whenever you try to move your wrist or flex it, even if you are just flexing your fingers. Sometimes your hand or arm may even become extremely numb when you fracture the wrist. The muscles in the area become tender and swell up. It is almost impossible to move the wrist after it gets fractured. The fracture causes the wrist or rather the hand to appear deformed. The area around the fracture might even get bruise and a fractured wrist also affects the blood flow in the area. You might even injure your ligaments, tendons, muscles or nerves.

Diagnosis
To confirm and check the level of severity, you are generally asked to get an X-ray done. In order to get a more detailed look at the fracture, you might have to undergo CT or MRI scans as well. Usually to treat a fracture, you will have to wear a splint and move your hand as least as possible. But keep moving you're your fingers otherwise they might get stiff. Your doctor will inform you from when you will be able to move your wrist. Until then try to keep your movements to the minimal.

Causes and Symptoms of Wrist Fracture

A fall or an injury is among the most common causes of a fracture. For a fracture to heal; the bones must be set in the correct position and a cast may need to be worn so as to hold them in place. This allows the bones to grow new tissue and bridge the break. The food you eat can help you speed up this process. Some of the best foods to build strong bones and help a fracture heal are:

Milk: Milk is one of the richest sources of calcium and vitamin D. It is also rich in proteins. These three elements are crucial to building strong bones. Proteins help the body release amino acids which in turn come together and create new tissue for the bones. Calcium is, of course, the building block of our bones. However, it is vitamin D that enables the body to absorb this calcium and utilize it. If you do not like the taste of milk, you could substitute it with yogurt. This dairy product is considered equally rich in proteins, calcium and vitamin D. In addition, it also contains amino acids such as glutamine and lysine that helps the bones absorb calcium.
Kale: Kale is known as a superfood. One of the reasons for this is the amount of calcium it contains. Kale is one of the few vegetables that are rich in this mineral. Thus, lactose intolerant people can get their required calcium from this vegetable. Kale can be eaten raw or cooked. Kale can also be juiced. However, to benefit fully from the vitamins and minerals in this vegetable, it is best to eat it raw.
Spinach: Spinach is another green leafy vegetable that is rich in calcium. It also contains zinc. Zinc helps stimulate the chemical reactions needed to bind calcium and other minerals together to create new bones. In addition, spinach is also a rich source of vitamin K. While this vitamin does not play a direct role in healing bones, it helps speed up the healing process.
Broccoli: Broccoli is a cruciferous vegetable that is rich in vitamin K1. This is very beneficial to your overall health and bone health. Vitamin K1 aids in the mineralization process of fusing broken bones together and building new bone tissue. Thus, it helps the bones set correctly.
Citrus Fruits: Fruits such as oranges are chock-full of vitamin C. This nutrient helps build a strong immune system and aids in the fracture healing process. Vitamin C also helps the body create collagen that surrounds the broken bones and allows it to heal faster.

Food Items That Help You Recover From Fractures!

Fractures are simply a break in a bone. They can be caused due to injury, (traumatic fractures) or a pre-existing condition like osteoporosis that causes weakening of bones (pathologic fractures). There are many ways to classify fractures. All fractures fall into the major categories of simple and compound fractures. Simple fractures are fractures where bones remain inside the skin and don t jut out. They are also called closed fractures.

Compound fractures, also called open fractures, are broken bones that penetrate through the skin. These types expose the bone and deep tissues to the environment. Compound fractures are more serious of the two. The healing here may be affected due to deep infections for which antibiotics need to be used. There are many different sub types of fractures and we re only going to skim through them here.

Comminuted fractures: Severe fractures in which a bone breaks into several smaller pieces.
Avulsion fractures: A small piece of bone is completely torn off from the main bone due to fierce pulling off a part of the body.
Other types of fractures are characterised by the many different angles the bone breaks into like transverse, oblique and spiral fractures.

Diagnosis
When a bone is broken there are symptoms like swelling that doesn t subside on its own and pain. In such a case it s imperative that one goes to a doctor for a diagnosis. Doctors can usually recognise most fractures by examining the injury and taking an X-ray. The X-ray also provides a clear idea about the type of fracture and the degree of displacement of the bone. And, it s important that the patient doesn t wait too long before approaching a doctor. This is because bones begin to heal very quickly after a fracture and the bone tissue will heal using any tissue available. This can lead to a misalignment of broken pieces of bone and cause disability and loss of function.

There are cases when X-ray may not show a fracture. This is especially common in fractures in the hip and wrist in older people. For diagnosing these, doctors will get some other tests done such as a computed tomography (CT) scan, magnetic resonance imaging (MRI), or a bone scan.

Treatments
Fractures have to be treated by doctors. The doctors set the fractured bones in their proper place and hold them there so that they can heal. Setting a bone is called "reduction." Reduction without surgery is called "closed reduction." But if the fracture is serious, it s going to require surgery with bone repositioning, called open reduction.

In extreme cases, pins, plates, screws, rods, or glue are used to hold the fractured bones in place, inside the body. Once the bone abutment has been treated, the bone is immobilised to allow the broken pieces to heal. In most cases, the fractured part is set in a rigid cast. The fractured ends of the bone can be fixed into place using metal pins connected to an external frame. This is removed after the bone has healed.
