A fracture, commonly known as a broken bone, occurs when a bone is subjected to more force than it can withstand. There are numerous types of fractures, each classified based on the nature and extent of the break. Understanding the different fracture types, their causes, risk factors, and healing times can aid in better management and recovery.
Read on to discover the most common fracture classifications and what to expect during the healing process.
What Exactly Does a Fracture Mean?
A fracture means that a bone has been broken, either partially or completely, due to excessive force or stress.
This break can occur in various ways, resulting in different types of fractures such as hairline fractures, open fractures, or bones shattered into multiple pieces. Fractures can be caused by accidents, falls, or medical conditions that weaken the bones. Proper diagnosis and treatment are crucial for effective healing and recovery.

Types of Fracture Listed by Severity
Fractures vary in severity, from minor hairline cracks to severe breaks that go through the skin, each requiring different levels of treatment and care. Here are some of the different types of fractures:
Hairline Fracture
A hairline fracture, or stress fracture, is a small crack in the bone that often results from repetitive stress or overuse. It typically heals with rest and may take several weeks to a few months to fully recover.
Greenstick Fracture
Common in children, a greenstick fracture occurs when the bone bends and cracks on one side but does not break completely. Treatment usually involves immobilization, and healing can take a few months.
Closed Fracture
A closed fracture, also known as a simple fracture, is a break in the bone that does not penetrate the skin. These fractures can vary in severity but generally heal within a few months with proper immobilization and care.
Open Fracture
An open fracture, also known as a compound fracture, occurs when the broken bone penetrates the skin, creating an external wound. This type of fracture poses a higher risk of infection due to exposure to external contaminants and often requires surgical intervention for proper cleaning, alignment, and stabilization of the bone.
Displaced/Unstable Fracture
A displaced or unstable fracture happens when the broken bone ends are out of alignment, requiring more complex treatment, often including surgery. The healing time can extend to several months, depending on the severity and the need for surgical intervention.
Nondisplaced/Stable Fracture
A nondisplaced fracture is when the bone cracks or breaks but maintains its proper alignment and the ends remain aligned. The surrounding soft tissues are typically minimally disrupted. Treatment typically involves casting or splinting, with a healing period of a few months.
Comminuted Fracture
A comminuted fracture is a severe type of break in which the bone shatters into two or more places. This type often necessitates surgery and more extensive rehabilitation.
Spiral Fracture
A spiral fracture occurs when one end of a bone remains in place while the other end is in motion. The force results in a twisting or spiral break in the bone. This type of fracture can be complicated to heal and require several months for a full recovery.
How Do You Know You Have a Fracture?
Diagnostic tests to determine if you have a fracture include:
- X-rays: This imaging technique provides detailed images of bones, helping identify fractures and assess their severity.
- Computed tomography(CT) scan: CT scans offer more detailed images than X-rays, especially for complex fractures or those in areas difficult to visualize.
- Magnetic resonance imaging (MRI): MRI scans are useful for detecting subtle fractures, especially in soft tissues around bones.
- Clinical examination: A thorough physical examination by a healthcare provider may reveal signs such as tenderness, deformity, or reduced range of motion, aiding in the diagnosis of fractures.
If you suspect a fracture, seeking medical attention promptly for an accurate diagnosis and appropriate treatment is crucial. The most common signs and symptoms of a fracture are:
- Immediate pain: A sharp, intense pain at the site of the injury, which may worsen with movement or pressure.
- Swelling and bruising: The area around the injury may swell and become bruised.
- Deformity: The affected limb or joint may appear deformed or out of place.
- Tenderness: The injured area may be extremely tender to touch.
- Reduced mobility: Limited movement in the affected area due to pain or mechanical obstruction.
Accident-Related Causes
Accident-related causes of fractures typically involve sudden, forceful impacts or traumatic events. Here are some common scenarios:
- Falling from a height, slipping, or tripping
- Car, motorcycle, or bicycle crashes
- Contact sports like football, basketball, or activities with a high risk of falls, such as skiing or skateboarding can cause fractures
- Receiving a direct hit to the body, such as in a physical altercation or being struck by an object
Prompt medical evaluation is essential following any of these incidents to assess for potential fractures and ensure proper treatment.
Condition-Related Causes
Condition-related causes of fractures are typically associated with underlying health issues that weaken the bones or make them more susceptible to breaking. Some common condition-related causes are:
- Osteoporosis: This condition weakens bones, making them more fragile and prone to fractures, often with minimal trauma or even spontaneous breaks.
- Untreated hyperthyroidism: Sufficient thyroid hormone levels are important for maintaining healthy bones, as they facilitate proper calcium absorption and regulate bone turnover. However, excessive thyroid hormone levels can disrupt this balance, leading to decreased calcium absorption and increased bone turnover, ultimately contributing to bone loss over time.
- Diabetes: Research indicates that people with type 1 diabetes face a heightened risk of low bone density and osteoporotic fractures. Poorly managed type 1 and type 2 diabetes often lead to hypoglycemic episodes (low blood sugar) and/or neuropathy (reduced sensation) in the feet, both of which can elevate the likelihood of falls and fractures.
- Chronic kidney disease: This condition can affect bone health, leading to bone weakness and an increased risk of fractures.
- Bowel diseases: Conditions like Crohn's disease, ulcerative colitis, and celiac disease can lead to malabsorption. This means the body has difficulty absorbing nutrients like calcium and vitamin D from food, resulting in lower levels of these essential nutrients. Consequently, bone loss can occur, increasing the risk of falls and fractures.
- Hyperparathyroidism: Overactivity of the parathyroid glands can lead to excessive calcium loss from bones, increasing fracture risk.
Managing these underlying conditions through appropriate medical treatment and lifestyle adjustments can help reduce the risk of fractures.
Can Obesity Increase Your Risk of Fractures?
Other Risk Factors
Several additional risk factors can increase the likelihood of fractures, including:
- Age: Advanced age leads to more fractures.
- Previous fractures: Having a history of fractures increases the likelihood of future fractures.
- Medications: Long-term corticosteroids and other medications that affect bone density can increase fracture risk.
- Smoking: Tobacco use can negatively affect bone health and slow down the healing process of fractures.
- Physical inactivity: Lack of regular exercise can lead to weaker bones and muscles, increasing fracture risk.
- Poor nutrition: Insufficient intake of calcium and vitamin D can weaken bones, making them more susceptible to fractures.
Addressing these risk factors through lifestyle changes, medical treatment, and preventive measures can help reduce the likelihood of fractures.
Describing Fracture Pain
Fracture pain is typically characterized by intense discomfort at the site of the injury. This pain can be accompanied by deformity, such as a limb appearing misaligned or out of place. Additionally, swelling, bruising, or tenderness around the injured area are common symptoms. Difficulty moving the affected part of the body is also often experienced.
If you suspect a fracture, seeking immediate medical attention is crucial for proper diagnosis and treatment.
Healing From a Fracture
Healing from a fracture is a gradual process that involves various stages of recovery and rehabilitation. The form of treatment will depend on the type of fracture you have.
Nonsurgical Treatment
The primary treatment for a fracture typically involves wearing a cast or splint, which immobilizes the bone during the healing process. The duration of wearing the cast or splint varies based on the fracture type and the affected bone, often spanning several weeks. Your healthcare provider will determine when it's appropriate to remove the cast or splint.
Surgical Treatment
In certain situations, surgery may be necessary to stabilize the bone using plates, pins, or screws.
Treatments may include:
- Traction: Gentle pulling to align or stretch bones
- External fixation: Inserting pins or screws from outside body to align the bones
- Open reduction: Surgical bone realignment with special screws, metal plates, or rods through the center of the bone
Healing Time
The healing time for a fracture can vary widely depending on factors such as the type and location of the fracture, the individual's overall health, and the treatment received. In general, most fractures take several weeks to several months to heal completely. Simple fractures may heal in about six to eight weeks, while more complex or severe fractures may require longer healing times, sometimes up to several months.
It's important to follow your healthcare provider's recommendations for recovery and rehabilitation to promote optimal healing and prevent complications.
Fracture Healing Complications
While the majority of bone injuries follow a normal healing trajectory, a subset of patients may encounter complications throughout the recovery period. These complications can be categorized into two groups: early and delayed.
Early complications include:
- Shock (a sudden drop in blood pressure)
- Infection
- Compartment syndrome (muscle swelling due to blood blockage)
- Deep vein thrombosis
Delayed complications include:
- Delayed union of bone
- Nonunion of bone
- Avascular necrosis (death of bone tissue because of lack of blood)
- Reactions to internal fixation devices such as screws or pins
Physical Therapy After Fracture
A physical therapist (PT) focuses on restoring physical function and mobility through exercises and therapies after an injury or condition like a fracture. PTs help treat fracture pain and discomfort in several ways, including:
- Exercises to keep joints moving
- Application of ice and heat
- Exercises to relieve muscle spasms
A PT can create a supervised program of exercises to help strengthen the body during healing. The goal of physical therapy is to help patients regain independence in daily activities and prevent future complications related to the fracture.
Physical therapists also help by performing range of motion and soft tissue release exercises for scars from surgery and/or to muscles that have become tightened after prolonged periods of immobility.
Movement and Daily Activity With a Fracture
After a fracture, it's crucial to follow your healthcare provider's guidance and any recommendations from your physical therapist regarding movement and daily activities. They can provide tailored advice on exercises, limitations, and gradual progression to help you regain mobility safely and prevent further injury during the healing process.
Summary
Fractures are common injuries that require proper diagnosis and treatment for optimal recovery. Understanding the types, causes, and healing process of fractures empowers individuals to take proactive steps toward their recovery and prevent potential complications. Remember to follow your healthcare provider's guidance to regain mobility safely after a fracture.
