Fibula Fracture Treatment | Fibula Bone Fracture Surgery

A fibula fracture can either be an incomplete of complete break in the two outside bones of the leg which are found between the ankles and the knees. Fibula injuries are common but cases of severe bone displacements are very rare. Most of the fractures on this body part are only characterized as ankle sprains. Fibula injuries can happen in any part of the fibula bone. However, since this bone receives only 17% of the body weight when a person is standing up, the injuries it develop is not as severe compared to other bones that bears a lot of weight.


Fibula Fracture Types

•    Type A- fibular fracture situated underneath the joints of the ankle

•    Type B- fibular fracture that occurs on the same level of the joint but with the  tibiofibular ligaments undamaged

•    Type C- fibular fracture that occurs above the level of the joint. This type causes tears and breaks on the neighboring syndesmotic ligaments.

Diagnosis

Diagnosis for fibula fractures requires physical examinations and a thorough record of health history of the patient. The health history of the patient is important because it will be the main source that can help the doctor to identify the extent of injury suffered. Regardless of the type and severity of the injury, the patient is required to have a neurovascular exam on his lower extremities and must have highly detailed ligamentous knee exam. In cases when the patient is suspected to have blunt trauma, an overall body checkup is required because blunt traumas usually never happen in isolated bodies only.

The doctor also usually asks for radiographic assessments with specific views of selected parts of the knee. The views usually requested from patients with fibular fractures are the AP, oblique, and lateral views of the knee and the AP, mortise, and lateral view angles of their ankles. Another requirement that the patient must undergo is the lateral and AP angle views of his fibula and tibia shaft. These are needed in order to properly evaluate the whole length of the injured leg. In some cases when instability of the knee is identified, the patient will also be asked for an MRI of his injured area.


Causes

The most common causes of fibula fractures are traumas from accidents like falling and repetitive stress. Elderly people are more prone into having this type of injury because of their fragile bones. Runners who constantly push their legs to the limit during training are also common candidates for fibula injuries. In cases when the fibula fracture is caused by repetitive application of stress, the injury is called as a ‘stress fracture’.


Fibula Fracture Symptoms

•    Moderate to extreme pain on the injured leg

•    Feeling of tenderness and noticeable swelling on the leg specifically on the calf part

•    Bruises and bleeding on the injured area

•    Extreme pain on the injured leg when weight is put on it

•    Noticeable deformity of the leg. This happens it if the fibular fracture is a complete type, with the bone fragments destroyed giving an appearance of a distortedly shaped leg.

•    Feeling of coldness or numbness from the leg beyond the site injured. This is the cause of the disturbed blood supply caused by the blockage of fractured bones.


Fibula Fracture Treatment

The preliminary treatment for fibula fractures involve non operative measures like the use of ice packs or leg elevation techniques to temporarily relieve the pain and swelling of the injured area. For semi-serious injuries wherein certain ligaments have been destroyed, the patient is prescribed to use crutches, casts, stirrup-type braces or walking boots until they recover. These tools are used to make sure that the broken bones will mend on their right places.

Only the severe cases when the fibula bones are fragmented into small pieces require surgery. In surgeries, plates, rods, or screws are implanted in the body to keep the small pieces of fractured bones together. In treating fibula fractures, whether there was a surgery or not, immobilization therapies are required to improve the injured area. Immobilization techniques include stretching, and strengthening exercises to make sure that the injured joints are still tended despite being kept on slings or casts.


Prevention

Individuals who have developed fibula fractures out of repeated stressful activities should take it easy on performing straining activities again. Athletes who are constantly training should keep this in mind. If possible, taking a few weeks of rest should be done to make sure that the fibula stress fractures could mend.


When to Call a Doctor

An individual experiencing pain after receiving blows on the legs and ankles should immediately consult a doctor. Others who are constantly engaging in stressful leg activities and feel pain on their legs should also go for a check-up because the sores can be the early signs of stress fractures.

Nondisplaced Fracture Treatment | Nondisplaced Bone Surgery

A bone fracture happens when a bone sustains a crack or a break due to a strong, high impact force from the outside, but there are also some fractures that are caused by average but constant impact. These bones need to be taken cared of carefully because they lend support, mobility, and protection to the internal organs. This is why an injured person’s movements would become restricted when a certain bone is fractured. There are certain ways in which a fracture injury is classified. One of the criteria used in the classification of injuries is whether the broken bone has a nondisplaced or displaced fracture. What is a nondisplaced fracture? A nondisplaced fracture happens when the affected bone is not really broken, which means it remains intact. This is opposite the displaced fractures wherein the break in the bone results to a deformity in the bone. Yet, extreme cases of fracture would result to a severely broken bone with a part of it already seen from the open wound after the rugge...

Displaced Fracture Treatment | Displaced Bone Fracture Surgery

The human bones have a flexibility level that makes it capable of resisting forces applied to it. However, once a powerful force that exceeds the resistance level of the bone is applied, the bone absorbs the shock causing it to break or fragment. Bone fractures are classified into two main types namely, the non-displaced and the displaced fractures. Most of the times non-displaced fractures are considered mild cases because even bones are fractured, the fragmented pieces still remained on their proper alignments. Displaced fractures, on the other hand, are considered more serious and severe because the bone fragments could be in many pieces and probably moved out of their proper positions. In displaced fractures, the distortion of the injured area is usually very visible and causes extreme bouts of pain. Types of Displaced Fractures • Open fracture - the fragmented bone pierces the skin, creating a wound. • Closed fracture - the bone is displaced but the skin is kept intact. ...

Ulnar Styloid Fracture Treatment | Symptoms | Healing Time

There are many bones and other structures that can be found on the wrist region. At the same time, there are other structures that support the wrist for its proper function.  The wrist is the piece of our body that is exceptionally versatile. It enables us to support actions that involve complex movements and it can also stand heavy force that we expect through its help. Because of this, it is not surprising that one can suffer from displaced or undisplaced fracture wrist. Wrist fracture is one of the most common types of bone fracture.  In fact, it is believed to comprise around one-fourth of total incidents of fracture of the limbs. The usual parts of the wrist that suffer from fracture injury are the distal radius and ulnar styloid (more commonly known as the ulna). On the other hand, the carpal parts of the wrist do not suffer much from fracture. There are only rare cases of fracture on the carpal areas. Identifying the right fracture diagnosis and treatment would ensur...
