Bone Fractures: Causes and Symptoms

'Fracture' is a medical term for a broken bone. According to an estimate, an average person has two fractures within their lifetime. When a force exerted is stronger than the bone itself, it can lead to a fracture. The risk and chance of fracture depend on your age. With age, bones tend to become brittle and, hence, a fall that would have been potentially harmless years ago can lead to a broken bone at a later age.

There are many types of bone fractures, but the main types are:

Closed fracture: A fracture in which the bone breaks but does not tear through the skin

Open fracture: Where the broken bone punctures through the skin and protrudes out. There's a greater chance of bone infection in an open fracture

Displaced fracture: In this type of fracture the bone snaps into more than two parts

Nondisplaced fracture: The bone cracks partly or wholly but it does continue to move

Some of the common signs and symptoms of a fracture are:

- Bruising and swelling of the bones
- Open fractures marked by protruding bones from the skin
- Loss of locomotive and functional ability of the injured area
- Deformity of the injured area
- Pain in the event of movement of the injured area

A fracture can be caused by a number of reasons, and they are:

- Injuries and accidents
- Falls and slips
- Wear and tear through overuse
- Sport injuries
- Fist fights and brawls
- Osteoporosis (a disease which causes bones to weaken in adults)
- Osteomalacia ( a disease caused due to softening of your bones, which is caused by a vitamin D deficiency.) Soft bones are more likely to bow and fracture than are harder, healthy bones.

Note:

Osteomalacia is not the same as osteoporosis. Osteomalacia occurs due to a defect in the bone-building process while osteoporosis develops due to a weakening of existing bones.



Bone Fractures: Causes and Symptoms

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


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

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?

The human body allows for movement through the complex system of bones, muscles and joints. A break in the bone is medically known as a fracture and can be caused by constant stress, pressure or impact. It is common knowledge that with age, the bone strength decreases and incidence of fractures (osteoporotic fracture) increases. Based on the affected bone and impact, different types of fractures are commonly identified as:

Complete: When the breakage of the bone is complete, producing two or more pieces, it is referred to as a complete fracture.
Incomplete: When the breakage is incomplete, where the bone has cracked, but does not break into pieces, it is known as an incomplete fracture.
Another type would be the open or closed fracture:
Open fracture: When the skin is exposed and the bone breaks through this exposed skin, it is known as compound or open fracture.
Simple or closed fracture: The bone breaks, but the skin continuity is maintained. Again, here are different types including hairline, greenstick, oblique, etc.
What is the reason behind a fracture?
A bone will fracture when force is applied to it that is stronger than the bone itself. A key factor in a bone s susceptibility to fracturing is age. Both children and older people are prone to bone fractures. Children s bones are constantly growing and have not reached their full strength. Elderly people have brittle bones with old age and are prone to develop bone diseases, making them susceptible to fractures.

How they are treated?
Splint and pain medications are commonly used. Closed reduction where the fracture is reduced without opening up the tissues and open reduction, where the tissues are opened up are common approaches to managing fractures.

Can they be prevented?
Especially with children and in the elderly, extra precaution should be taken to avoid any kind of injury and fracture.

Develop an exercise routine to strengthen the muscles
Manage weight
Use the right footwear and exercise gear
Watch your medications (avoid sleep inducing ones)
Increase lighting in the room/home to improve clarity of vision for elderly
Make the home/living area fall-proof by reducing clutter, using railing in the bathroom and bedroom, using rubber mat, etc.
While a fall may seem inevitable, taking the above steps can help reduce the incidence and severity of a fall, thereby minimizing damage.

Bone Fracture - Common Types and How They Can be Prevented?

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.
