Types of Bone Fractures

Fracture of Bones is a medical condition in which there is a partial or complete break in the continuity of the bone. In more severe cases, the bone may be broken into several pieces.[rx] A bone fracture may be the result of high force impact or stress, or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis, osteopenia, bone cancer, or osteogenesis imperfecta, where the fracture is then properly termed a pathologic fracture.[rx]

Types of Fracture of Bones

According to Mechanism

  • Traumatic fracture – This is a fracture due to sustained trauma. e.g., fractures caused by a fall, road traffic accident, fight, etc.
  • Pathologic fracture – A fracture through a bone that has been made weak by some underlying disease is called a pathological fracture. e.g., a fracture through a bone weakened by metastasis. Osteoporosis is the most common cause of pathological fracture.
  • Periprosthetic fracture – This is a fracture at the point of mechanical weakness at the end of an implant

According to Soft-tissue involvement

  • Closed fractures are those in which the overlying skin is intact
  • Open/compound fractures involve wounds that communicate with the fracture, or where fracture hematoma is exposed, and may thus expose the bone to contamination. Open injuries carry a higher risk of infection.
    • Clean fracture
    • Contaminated fracture

According to Displacement

  • Non-displaced
  • Displaced
    • Translated, or ad latus, with sideways displacement.[rx]
    • Angulated
    • Rotated
    • Shortened

According to Fracture Pattern

  • Linear fracture – A fracture that is parallel to the bone’s long axis
  • Transverse fracture – A fracture that is at a right angle to the bone’s long axis
  • Oblique fracture – A fracture that is diagonal to a bone’s long axis (more than 30°)
  • Spiral fracture – A fracture where at least one part of the bone has been twisted
  • Compression fracture/wedge fracture – usually occurs in the vertebrae, for example when the front portion of a vertebra in the spine collapses due to osteoporosis (a medical condition that causes bones to become brittle and susceptible to fracture, with or without trauma)
  • Impacted fracture – A fracture caused when bone fragments are driven into each other
  • Avulsion fracture – A fracture where a fragment of bone is separated from the main mass

According to Fragments Involvement

  • An incomplete fracture – This is a fracture in which the bone fragments are still partially joined, in such cases, there is a crack in the osseous tissue that does not completely traverse the width of the bone.
  • A complete fracture – This is a fracture in which bone fragments separately.
  • A comminuted fracture – This is a fracture in which the bone has broken into several pieces.

According to Shape Bone Fractures

To classify your bone fracture, your doctor will see where the bone has been broken and the shape or pattern of the break. A bone fracture can take several different forms, which will ultimately dictate your treatment. Here are some of the most common:

  • Open Fracture – In this injury, the bone breaks through the skin, causing a severe wound. Also called a compound fracture, an open fracture should be tended to immediately to prevent infection.
  • Stress Fracture – Stress fractures look like a hairline crack in the bone and can be hard to see on a regular X-ray. Runners are prone to stress fractures because of the repetitive motion of hitting the pavement.
  • Greenstick Fracture – In a greenstick fracture, the bone bends and breaks, but remains in one piece. This is often seen in children due to their softer, more flexible bones.
  • Transverse Fracture – A transverse fracture is characterized by a horizontal break across the bone. It is often the result of a traumatic event like a car accident.
  • Oblique Fracture – In an oblique fracture, the break has a curved or angled pattern within the bone.
  • Comminuted Fracture – When the bone shatters into three or more pieces it’s known as a comminuted fracture. Sometimes, bone fragments break away and embed in the site of the fracture. High-impact trauma such as a car accident typically causes a comminuted fracture.
  • Linear Fracture – Instead of a horizontal break across the bone, a linear fracture is vertical and parallel to the sides of the bone.
  • Compression Fracture – Compression fractures are the result of the crushing of the bone. This type of fracture typically occurs in the spine when the vertebrae collapse because of bone loss due to osteoporosis.
  • Displaced Fracture – In most fractures, the bone breaks but remains in alignment. With a displaced fracture, the bone breaks into two or more pieces and is shifted out of alignment due to the force of the trauma.
  • Spiral Fracture – The defining characteristic of a spiral fracture is a break that spirals around the bone. It’s frequently seen in the long bones of the body, such as the femur, tibia, or fibula in the legs. The most common causes of a spiral fracture are accidents or sports injuries.

Symptoms of Fracture of Bones

Although bone tissue itself contains no nociceptors, the bone fracture is painful for several reasons:[rx]

  • Breaking in the continuity of the periosteum, with or without similar discontinuity in endosteum, as both contain multiple pain receptors.
  • Edema of nearby soft tissues caused by bleeding of broken periosteal blood vessels evokes pressure pain.
  • Involuntary muscle spasms trying to hold bone fragments in place.
  • Hematoma on the fracture site.

Damage to adjacent structures such as nerves, muscles or blood vessels, spinal cord, and nerve roots (for spine fractures), or cranial contents (for skull fractures) may cause other specific signs and symptoms.

Diagnosis

History

Your doctor in the emergency department may ask the following questions

  • How – How was the fracture created, and, if chronic, why is it still open? (underlying etiology)
  • When – How long has this fracture been present? (e.g., chronic less than 1 month or acute, more than 6 months)
  • What – What anatomy and structure do it involve? (e.g., epidermis, dermis, subcutaneous tissue, fascia, muscle, tendon, bone, arteries, nerves). What comorbidities, economic or social factors do the patient have which might affect their ability to heal the fracture?
  • Where – Where on the body parts is it located? Is it in an area that is difficult to offload, complicated, or keep clean? Is it in an area of high skin tension? Is it near any vital organ and structures such as a major artery?
  • What is your Past – Has your previous medical history of fracture? Are you suffering from any chronic disease, such as hypertension, blood pressure, diabetes mellitus, or previous major surgery? What kind of medicine did you take? What is your food habits, geographic location, Alcohol, tea, coffee consumption habit,  anabolic steroid uses for athletes, etc?

Physical

Physical examination is done by your doctor, consisting of palpation of the fracture site, eliciting boney tenderness, edema, and swelling. If the fracture is in the dept of a joint, the joint motion, and normal movement will aggravate the pain.

  • Inspection – Your doctor also checks superficial tissue, and skin color, involving or not only the epidermal layer or Partial-thickness affects the epidermis and extend into the dermis, but full thickness also extends through the dermis and into the adipose tissues or full-thickness extends through the dermis, and adipose exposes muscle, bone, evaluate and measure the depth, length, and width of the fracture. Access surrounding skin tissue, fracture margins for tunneling, rolled, undermining fibrotic changes, and if unattached and evaluate for signs and symptoms of infection warm, pain, and delayed healing.
  • Palpation – Physical examination may reveal tenderness to palpation, swelling, edema, tenderness, worm, temperature, open fracture, closed fracture, microtrauma, and ecchymosis at the site of fracture. Condition of the surrounding skin and soft tissue, quality of vascular perfusion and pulses, and the integrity of nerve function.
  • Motor function – Your doctor may ask the patient to move the injured area to assist in assessing muscle, ligament, and tendon function. The ability to move the joint means only that the muscles and tendons work properly, and does not guarantee bone integrity or stability. The concept that “it can’t be fractured because you can move it” is not correct. The jerk test and manual test are also performed to investigate the motor function.
  • Sensory examination – assesses sensations such as light touch, worm, paresthesia, itching, numbness, and pinprick sensations, in its fracture side. Sensory 2-point discrimination
  • Range of motion – A range of motion examination of the fracture associate joint and it’s surrounding joint may help assess the muscle, tendon, ligament, and cartilage stability. Active assisted, actively resisted exercises are performed around the injured area joint.
  • Blood pressure and pulse check – Blood pressure is the term used to describe the strength of blood with which your blood pushes on the sides of your arteries as it’s pumped around your body. An examination of the circulatory system, feeling for pulses, and blood pressure, and assessing how quickly blood returns to the tip of a toe to the heart and it is pressed the toe turns white (capillary refill).

Lab Test

Laboratory tests should be done as an adjunct to the overall medical status for surgical treatment.

Treatment

First Aid

First aid steps include:

  • Check the person’s airway and breathing. If necessary, call 911 and begin rescue breathing, CPR, or bleeding control.
  • Keep the person still and calm.
  • Examine the person closely for other injuries.
  • In most cases, if medical help responds quickly, allow the medical personnel to take further action.
  • If the skin is broken, it should be treated right away to prevent infection. Call emergency help right away. DO NOT breathe on the wound or probe it. Try to cover the wound to avoid further contamination. Cover with sterile dressings if they are available. Don’t try to line up the fracture unless you are medically trained to do so.
  • If needed, immobilize the broken bone with a splint or sling. Possible splints include a rolled-up newspaper or strips of wood. Immobilize the area both above and below the injured bone.
  • Apply ice packs to reduce pain and swelling. Elevating the limb can also help to reduce swelling.
  • Take steps to prevent shock. Lay the person flat, elevate the feet about 12 inches (30 centimeters) above the head, and cover the person with a coat or blanket. However, DO NOT move the person if a head, neck, or back injury is suspected.
  • Check the person’s blood circulation. Press firmly over the skin beyond the fracture site. (For example, if the fracture is in the leg, press on the foot). It should first blanch white and then “pink up” in about 2 seconds. Signs that circulation is inadequate include pale or blue skin, numbness or tingling, and loss of pulse.

If circulation is poor and trained personnel are NOT quickly available, try to realign the limb into a normal resting position. This will reduce swelling, pain, and damage to the tissues from lack of blood.

Do no HARM for 72 hours after injury

  • Heat – Heat applied to fracture and injured side by hot baths, electric heat, saunas, heat packs, etc has the opposite effect on the blood flow. Heat may cause more fluid accumulation in the fracture joints by encouraging blood flow. Heat should be avoided when inflammation is developing in the acute stage. However, after about 72 hours, no further inflammation is likely to develop and heat can be soothing.
  • Alcohol –  stimulates the central nervous system which can increase bleeding and swelling and decrease healing.
  • Running and movement – Running and walking may cause further damage, and causes healing delay.
  • Massage A massage also may increase bleeding and swelling. However, after 72 hours of your fracture, you can take a simple message, and applying heat may be soothing the pain.

Medication

The following medications may be considered by your doctor to relieve acute and immediate pain, long-term treatment

What To Eat and What  to avoid

Eat Nutritiously During Your Recovery

All bones and tissues in the body need certain micronutrients to heal properly and promptly. Eating a nutritious and balanced diet that includes lots of minerals and vitamins is proven to help heal broken bones and all types of fractures. Therefore, focus on eating lots of fresh food produce (fruits and veggies), whole grains, cereal, beans, lean meats, seafood, and fish to give your body the building blocks needed to properly repair your fracture. In addition, drink plenty of purified mineral water, milk, and other dairy-based beverages to augment what you eat.

  • Broken bones or fractured bones need ample minerals (calcium, phosphorus, magnesium, boron, selenium, omega-3) and protein to become strong and healthy again.
  • Excellent sources of minerals/protein include dairy products, tofu, beans, broccoli, nuts and seeds, sardines, sea fish, and salmon.
  • Important vitamins that are needed for bone healing include vitamin C (needed to make collagen your body’s essential element), vitamin D (crucial for mineral absorption, or machine for mineral absorber from your food), and vitamin K (binds calcium to bones and triggers more quickly collagen formation).
  • Conversely, don’t consume food or drink that is known to impair bone/tissue healing, such as alcoholic beverages, sodas, fried fast food, most fast food items, and foods made with lots of refined sugars and preservatives.

Complications

An old fracture with nonunion of the fracture fragments

Some fractures may lead to serious complications including a condition known as compartment syndrome. If not treated, eventually, compartment syndrome may require amputation of the affected limb. Other complications may include non-union, where the fractured bone fails to heal, or mal-union, where the fractured bone heals in a deformed manner.

Complications of fractures may be classified into three broad groups, depending upon their time of occurrence. These are as follows –

  • Immediate complications – occur at the time of the fracture.
  • Early complications – occur in the initial few days after the fracture.
  • Late complications – occur a long time after the fracture.

Key points about fractures

  • A fracture is a partial or complete break in the bone. There are many different types of fractures.
  • Bone fractures are often caused by falls, trauma, or as a result of a direct blow or kick to the body. Overuse or repetitive motions can cause stress fractures. Fractures can also be caused by diseases that weaken the bone. These include osteoporosis or cancer in the bones.
  • The main goal of treatment is to put the pieces of bone back in place so the bone can heal. This can be done with a splint, cast, surgery, or traction.
  • You should see a healthcare provider any time you think you may have a broken bone.

Next steps

Tips to help you get the most from a visit to your healthcare provider:

  • Know the reason for your visit and what you want to happen.
  • Before your visit, write down questions you want to be answered.
  • Bring someone with you to help you ask questions and remember what your provider tells you.
  • At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also, write down any new instructions your provider gives you.
  • Know why a new medicine or treatment is prescribed, and how it will help you. Also, know what the side effects are.
  • Ask if your condition can be treated in other ways.
  • Know why a test or procedure is recommended and what the results could mean.
  • Know what to expect if you do not take the medicine or have the test or procedure.
  • If you have a follow-up appointment, write down the date, time, and purpose for that visit.
  • Know how you can contact your provider if you have questions.
