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.

Distal phalanx injuries

Tuft: Simple or comminuted fracture
Soft tissue distortion may suggest nailbed injury shift: Longitudinal or transverse fracture
Intraarticular (DIP) injury
Jersey finger: Distal FDP injury; ± volar avulsion fragment; unable to flex the DIP
Mallet finger: DIP flexion due to terminal extensor tendon injury; ± dorsal avulsion fragment
DIP joint dislocation: Typically dorsal or lateral
Often associated with significant soft tissue injury due to tight soft tissue sleeve in distal digits

Epiphyseal injuries

Child: Salter-Harris type I or II
Adolescent: Salter-Harris type II or III
Displacement of fracture fragment may mimic dislocation

Middle/proximal phalanx injuries

Intraarticular (PIP) injury

Condylar: Unicondylar, bicondylar, or comminuted fracture may be missed clinically because the finger still flexes. Associated with significant soft tissue injury
Base: Avulsion or impaction fracture
Boutonnière injury: PIP flexion with DIP extension due to extensor tendon central slip injury; ± dorsal avulsion middle phalanx base solar plate injury: Typically distal volar plate injured; ± volar avulsion of the base of middle phalanx
Collateral ligament injury: Asymmetric joint widening; radial collateral ligament (RCL) > UCL; ± lateral avulsion fracture
Comminuted impaction (pilon) fracture: Central depression with splaying of articular margin lateral plateau fracture: Typically involves middle phalanx base
Dislocation: Dorsal PIP is the most common
Coach’s finger: Dorsal dislocation of middle phalanx base on proximal phalanx head; ± volar plate injury
Physeal fractures: 85-90% are Salter-Harris type II Typically small finger with medial angulation

Extraarticular fractures

Sub capital: Common in children; frequently overlooked
Head fragment may displace and rotate 90° dorsally
Spiral/oblique fracture: Proximal phalanx is the most common
Transverse fracture: Middle phalanx is the most common

MCP injury of fingers

Proximal phalanx dorsal dislocation/subluxation; ± avulsion or osteochondral shear fracture joint space widening; medial or lateral angulation. Look for sesamoid interposed in MCP, which Indicates volar plate injury

Thumb MCP injury

Joint subluxation or widening suggests collateral ligament injury
Asymmetric widening of medial or lateral joint > 30° with flexion/extension difference between injured and uninjured joint > 15° suggests ligament injury
UCL injuries 10x more frequent than RCL injuries
Look for associated fracture fragment, typically from the ulnar base of proximal phalanx
Mallet thumb: Rare; extensor pollicis longus tear; ± dorsal avulsion

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.

CBC, ESR test
Random blood sugar, glucose, and routine diabetes test if the patient has diabetes mellitus.
Microscopic urine examination test, and stool test.
ECG, EKG test for heart abnormality is present
Ultrasonography test in some cases.
Normalized hemoglobin, hematocrit test
Coagulation profile with bleeding time and coagulation time test, prothrombin time (PT) test for surgery if needed,
Partial thromboplastin time (PTT), and platelet counts will be needed for operative intervention.
Serum creatinine test,
Serum lipid profile
Serum uric acid test

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

Antibiotic – Cefuroxime or Azithromycin, Flucloxacillin or any other cephalosporin/quinolone, meropenem antibiotic must be used to prevent infection or clotted blood removal to prevent further swelling, inflammation, and edema.
NSAIDs – Prescription-strength drugs that reduce both pain and inflammation. Pain medicines and anti-inflammatory drugs help to relieve pain and stiffness, allowing for increased mobility and exercise. There are many common over-the-counter medicines called non-steroidal anti-inflammatory drugs (NSAIDs). They include first-choice NSAIDs is Ketorolac, then Etoricoxib, then Aceclofenac, and naproxen. As you are taking pain medication or NSAIDs, your doctor must prescribe a standard anti-ulcer drug, such as omeprazole, pantoprazole, esomeprazole, dexlansoprazole, etc.
Muscle Relaxants – These medications provide relief from spinal muscle spasms and spasticity. Muscle relaxants, such as baclofen, tolperisone, eperisone, methocarbamol, carisoprodol, and cyclobenzaprine, may be prescribed to control postoperative muscle spasms, spasticity, stiffness, and contracture.
Calcium & vitamin D3 – To improve bone health, blood clotting, helping muscles to contract, regulating heart rhythms, nerve functions, and healing fractures. As a general rule, too absorbed more minerals for men and women aged 50 and older should consume 1,200 milligrams of calcium a day, and 600 international units of vitamin D a day to heal back pain, fractures, and osteoarthritis.
Neuropathic Agents – Drugs(pregabalin & gabapentin) that address neuropathic—or nerve-related—pain. This includes burning, numbness, tingling sensation, and paresthesia .
Glucosamine & Diacerein, Chondroitin sulfate – can be used to tighten the loose tendon, cartilage, ligament, and cartilage, ligament regenerates cartilage or inhabits the further degeneration of cartilage, ligament. The dosage of glucosamine is 15oo mg per day in divided dosage and chondroitin sulfate is approximately 500mg per day in different dosages, and diacerein minimum of 50 mg per day may be taken if the patient suffers from osteoarthritis, rheumatoid arthritis, and any degenerative joint disease.[rx]
Topical Medications and essential oil – These prescription-strength creams, gels, ointments, patches, and sprays help relieve pain and inflammation in acute trauma, pain, swelling, and tenderness through the skin. If the fracture is closed and not open fracture then you can use this item.
Antidepressants – A drug that blocks pain messages from your brain and boosts the effects of endorphins in your body’s natural painkillers. It also helps in neuropathic pain, anxiety, tension, and proper sleep.
Corticosteroids – Also known as oral steroids, these medications reduce inflammation. To heal the nerve inflammation and clotted blood in the joints.
Dietary supplement – To eradicate the healing process from fracture your body needs a huge amount of vitamin C, and vitamin E. From your dietary supplement, you can get it, and also need to remove general weaknesses & improve your health.
Cough Syrup – If your doctor finds any chest congestion or fracture-related injury in your chest, dyspnoea, or post-surgical breathing problem, then advise you to take bronchodilator cough syrup.

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.

Immediate complications	Early complications	Late complications
Systemic Hypovolaemic shock	Systemic Hypovolaemic shock ARDS – Adult respiratory distress syndrome Fat embolism syndrome Deep vein thrombosis Pulmonary syndrome Aseptic traumatic fever Septicemia (in open fracture ) Crush syndrome	Imperfect union of the fracture Delayed union Nonunion Malunion Cross union
Local Injury to major vessels Injury to muscles and tendons Injury to joints Injury to viscera	Local Infection Compartment syndrome	Others Avascular necrosis Shortening Joint stiffness Sudeck’s dystrophy Osteomyelitis Ischaemic contracture Myositis ossificans Osteoarthritis

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:
