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

A small piece of bone is known as a fragment and it is very common that an avulsion fracture also tends to damage the protrusions of bone to which the tendons attach. This basically means that the tendon or ligament will come away from the bone and it will take a small piece of bone with it. It is sometimes very hard to find out what type of injury you have and this is why knowing the causes and symptoms of an avulsion fracture are very helpful in determining exactly how severe the injury is. 
Here are the causes of an avulsion fracture.
Causes:
Explosive Landing: Athletes who tend to jump or land with great impact tend to get these most commonly. Therefore, it is crucial for your health that if you participate in such sports, you do follow the correct method of jumping.
Explosive Extension: Similar to how an athlete landing ferociously can get an avulsion fracture, someone who is extending the legs very violently and explosively during an exercise can also get an avulsion fracture. This is because the bone getting extended could very well damage the protrusions to which the tendons are attached. 
Symptoms:
These are the two main causes of an avulsion fracture. There are not many symptoms of an avulsion fracture. This is because an avulsion fracture can only be determined by an MRI or by an X-ray scan. Therefore it is nearly impossible to diagnose that you have an avulsion fracture without looking at the results of the tests performed on the part of your body. However, the way you got the fracture and especially the details of it are very good indications of whether you have an avulsion fracture or not.


Causes and Symptoms of Avulsion Fracture

Spinal fractures occur as a result of an injury or dislocation of the bony vertebra. This causes the bone fragments to pinch and damage the spinal cord. Fractures can occur anywhere along the spine but the most common site of fracture is the lower back.

What causes spinal fractures?

Spinal fractures are often a result of the following-

  A sudden traumatic injury
  A high-velocity accident
  Falling from a height
  Sports injuries
  Spinal instability
  A whiplash

Types of spinal fractures:

Spinal fractures are classified into three categories, such as the following-

  Compression fracture - If you exert excessive pressure on the vertebra, it will break. This type of fracture occurs when the bones in the spine become fragile or weak to the extent that they easily crumble. People living with osteoporosis, certain types of cancer or tumours are prone to a compression fracture.

  Dislocation - When the discs and/or ligaments linking the vertebrae is torn or stretched, the bones may dislocate or come out of alignment.

  Fracture-dislocation - Torn ligament and broken bone lead to this condition. A fracture-dislocation is a debilitating condition and often requires surgical intervention.

Symptoms of spine fractures:

Following an accident or an injury, you can tell if you have ended up fracturing your spinal column by identifying these symptoms-

  Excruciating pain
  Tingling sensation
  Numbness
  Muscle spasm
  Swelling of the muscle
  Sudden onset of back pain
  Restricted spinal mobility
  The pain worsens if you walk or stand for long
  Deformity or disability of the spine

How are spinal fractures treated?

Spinal fracture treatment begins with administering pain-management drugs and medications to ease the symptoms, and stabilization methods to prevent injury. Depending on the nature of the fracture, your doctor may follow these lines of treatment-

  Fusion and instrumentation - These are surgical procedures to cure unstable fractures. Fusion refers to the joining of the vertebrae using a bone graft along with hardware such as hooks, rods, plates, or pedicle screws. The bone graft joins the vertebrae below and above to form a solid piece of bone.

  Kyphoplasty and vertebroplasty - These are minimally invasive procedures, wherein the surgeon injects bone cement into the fractured body through a needle. During kyphoplasty, the surgeon first inserts and inflates a balloon to expand the compressed vertebrae and then fills it with bone cement.

Spinal fractures are an extremely uncomfortable and painful condition to live with. It can hinder your day-to-day activities and affect your quality of life. It is imperative that you seek immediate treatment if you end up with fractures or dislocation of the spine.

Spine Fracture - How Can You Get It Fixed?

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.

Fractures - How To Diagnose Them?

A bone fracture occurs when a strong external force is applied on the bones causing it to break. It is an extremely painful condition that results in days of immobility and rest. There are several reasons which can result in bone fracture, some of them being:

1. Injuries caused in sports
Any sport requires and demands extreme physical exertion and participation. Being involved in any sport therefore automatically increases your risk of incurring injuries. Bone fractures therefore are mostly reported during sports.

2. Osteoporosis
Due to the deficiency of calcium, the bones of both men and women tend to get weak and more susceptible to fracture and breakage. It is one of the primary causes that lead to bone fracture.

3. Osteomalacia
This also refers to a condition wherein the bones become weak and brittle. Much like osteoporosis, osteomalacia too significantly contributes to instances of bone fractures.

4. Osteosarcoma
This is a rare form of bone cancer that most often develops either near the femur or near the shinbone. An instance of this form of bone cancer is most often found in children and weakens the bone, consequently leading to fractures.

Though there may be different causes of broken fractures, its symptoms remain similar. Some of them are-

1. Swelling
One of the most common symptoms of bone fracture is perceptible swelling. If any of your bone is fractured, that particular part will be visibly swollen.

2. Deformity
Bones give your body the shape it has, thereby, any fracture anywhere would inevitably manifest itself as a clear deformity of that particular part.

3. Extreme pain
It goes without saying that a bone fracture would entail excruciating and extreme pain. This pain sharply increases with mobility thereby necessitating complete rest.

4. Temporary loss of function
The part of the body where the bone is broken temporarily becomes dysfunctional. For instance, if the bone in your hand is broken, you will find it extremely difficult to move and do any work with it.

Causes and Symptoms of Bone Fracture

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.
