Ankle and Feet | Fractures | Symptoms, Causes and Treatments

Fractures

Bones are rigid structures in the human body, but they can sometimes bend, crack, or break when a strong force is applied externally. In addition to causing pain, fractures may also cause dysfunction in the affected bones. Fractured bones may need treatment, depending on the severity of the fracture.

What is a fracture?

Fracture is the medical term for a cracked or broken bone. Any bone in the body is susceptible to it. When an external force is exerted that is greater than the bone itself, a fracture results.

The severity of the fracture depends on the force that resulted in the breakage. If the force is slightly above the breaking point of the bone, it can lead to a crack. On the other hand, an extremely high force that occurs during an automobile accident or a gunshot can led to the shattering of the bones.

There are numerous ways in which fractures can occur, including:

Closed fracture: a fracture that does break through the skin and is not exposed to the atmosphere

Open/compound fracture: a fracture that damages the nearby tissues, and penetrates the skin and is exposed to the atmosphere

Comminuted fracture: a fracture in which the bone shatters into pieces

What are the symptoms of a fracture?

Fractures can lead to severe pain and can make it almost impossible to move the associated joint or limb. The other common symptoms of a fracture are:

Swelling and tenderness
Bruising
Deformities
Puncture of the bone through the skin or an out-of-place limb

What are the causes and risk factors of fractures?

The common causes of fractures are:

Trauma such as a motor vehicle accident, a fall, or a sporting injury
Osteoporosis, a condition which leads to the decreased density and diminished interlinking, leads to fragility, making them more susceptible to fractures
Overuse or repetitve trauma, leading to stress fractures

The risk of fractures is high in the following groups of people:

Older people are at increased risk of falling due to the increased risk of falls and weakening of bones with age
Children who engage in physical activities
People with underlying conditions such as osteoporosis, a tumor, or certain infections
Sports professionals who are exposed to repeated stress and strains

How is plantar fracture diagnosed?

A physical examination may be performed to assess the condition and the extent of the injury. A medical history of the patient may help determine the cause of the injury.

Usually, an X-ray is good enough to diagnose a fracture. The X-rays can show the presence of a fracture, the type of fracture, and the exact location of the bone.

What are the treatment options?

In most cases, bones can heal without any intervention if they are not displaced or immobilized. However, treatment is necessary to provide the injured bone with the best conditions to heal properly.

The treatment aims at restoring the function of the bone to its fullest. Treatment options for a fracture include:

Cast immobilisation

A fibreglass cast or a plastic cast is applied upon repositioning the broken ends of the bones in place to allow for a successful healing. This is the most common treatment of a fracture.

Fracture reduction/ reposition

The ends of the bones are properly aligned to help in the natural healing process. This is known as fracture reduction and is performed under general anaesthesia. It may be performed by techniques such as manipulation, closed reduction, etc.

Functional cast or brace

A cast or a brace limits or controls the movement of the adjacent joints and is effective in treating certain fractures.

Traction

A gentle and steady pulling known as traction helps in aligning the bones that may be over-riding.

External fixation

This method involves inserting metal pins or screws above and below the fracture site of the bone. The pins or screws are attached to a metal bar externally (i.e. outside the skin) to hold the bone in proper position and allow healing.

Internal fixation

In this method, following fracture reduction, the screws or metal plates are attached to the outer surface of the bone. Rods are inserted down through the marrow space to hold the broken bone fragments together.

Physical therapy

Certain exercises, as suggested by the physiotherapist, can help to restore the muscle strength and improve the mobility of the affected joint.

Surgery

Plastic surgery may be necessary in the case of compound fractures.

Outlook

It takes several months for a fracture to heal completely, depending on the severity and the care taken by the patient. Also, the time of healing depends on the age and overall health of the individual.

Although the pain lasts for a short time, it is advisable to follow the doctor's instructions and limit normal activities until the bone is strong enough.
