Types causes symptoms and treatment of bone fracture and dislocation
Dislocations and fractures are the two most common bone and joint injuries. If the bone slips or moves from the joints, it is known as the dislocation of bones. This mainly occurs due to the sudden impact of a forceful blow or other trauma. The dislocation of bones is common in ankles, knees, hips, shoulders, jaws, fingers, toes, or elbows.
When extreme pressure is applied to the bone, it split or breaks into few pieces. This is known as a fracture. The main causes for fracture are trauma, accident, repetitive stress, the direct blow of pressure, and weakness of bones. Children have more possibility to face fracture.
Types of Fracture
The fractures are mainly classified into three types. They are open fracture, closed fracture, and displaced fracture.
Open Fracture
If the bone is broken with the opening of the skin, it is known as an open fracture. Open fracture gets infected soon. An open fracture requires immediate medication and surgery for better treatment. Surgeons suggest rods and screw for treating the open fracture.
Closed Fracture
Closed fracture has more risk than open fracture. The bone inside the skin gets injured but the skin on closed fracture remains the same. This can be identified using an x-ray. Immobilization of the injured areas is the best treatment for closed fractures.
Displaced Fracture
If the bones are broken into two or more pieces, they are known as displaced fractures. It causes swelling. Keeping the injured area undisturbed be the best treatment for the displaced fracture. Sometimes, experts suggest surgery.
Fractures are subclassified into 10 types. The fracture sub classification comes under open, closed, and displaced fractures. They are listed below.
Transverse Fracture - It looks like a straight line of a crack in a bone.
Spiral Fracture - It usually occurs in long bones, the fracture looks like a spiral in shape.
Greenstick Fracture - Occurs due to bent or broken bones. These fractures mainly occur in children. It is also known as a partial fracture.
Stress Fracture - Stress fractures occur mainly due to repetitive actions like running. It is difficult to diagnose through x-ray. These fractures are also known as hairline fractures
Compression Fracture - This fracture occurs in broken bones. Here, the broken bones will become wider or flatter.
Oblique Fracture - The bone across the diagonal structure is known as oblique fracture
Segmental Fracture - If the same bone broken in two places and left a piece of bone floating is known as a segmental fracture. This type of fracture usually occurs in long bones.
Impacted Fracture - The impacted fracture occurs in the bone if the two broken pieces are jammed together by an external force.
Avulsion Fracture - when a fragment is pulled off the bone causes a tendon or ligament. It is known as an avulsion fracture.
Comminuted Fracture - If the bones are broken into 3 or more pieces, then it is known as a comminuted fracture.

Difference Between Fracture and Dislocation
Fracture mainly occurs due to breaks or cracks in the bone. While dislocation occurs at the connecting joins of bone mainly due to the displacement of bones. The symptoms of fracture dislocation are common. Both look similar before the medical examination.
Symptoms of Fractures
Bleeding, Tenderness, Deformity, severe pain and discomforts, broken skin during open fracture, loss of motion, swelling...etc.
Symptoms of Dislocations
Dislocations cause swelling, immobility at the affected part, intense pain, burning, instability..etc. It is difficult to identify the dislocation of bones with a physical examination.
Only X-ray and scanning are important to diagnose and differentiate fracture and dislocation. Only after the proper diagnosis method, physicians can offer more for the treatment.
Dislocation and Fracture Risk Factors
Fracture dislocation is dangerous and it cannot leave as untreated. The person in the sports field or who is lifting heavy weight or who is working in heights have a high chance to face fractures and dislocation. Other risk factors are accidents, genetic disorders, traumatic events..etc.
List of Factors, Which Increases the Risk of Fracture are:
Smoking
Steroids
Drinking alcohol
Rheumatoid arthritis
Diabetes
Osteoporosis
Previous low-impact fractures
Crohn’s disease, Celiac disease, and ulcerative colitis
Fracture and Dislocation Treatment
Leaving the fractured or dislocated bone untreated is more dangerous, it can cause severe impacts. It is preferable to contact a trauma specialist for the best remedy. Physicians will start to treat fractures and dislocation only after researching the medical history of patients. They examine the age of patients, bone type, cause, defect rate, rehabilitation rate of the bones to treat the fracture and dislocation. The bone will start to reconstruct after a few weeks to a month of treatment.
The major fracture treatments are of two types. They are plaster and fibreglass cast methods. In extreme cases, splints, braces, and surgery are preferred to treat, it mainly depends on the type and severity of the fracture. Usually, bone has the capability to rebuild on its own, it remains undisturbed. Doctors can treat fracture dislocation through splint or orthopaedic cast or surgery or regular physiotherapist therapy or through medication to promote bone health
FAQs on Fracture and Dislocation of Bone Explained for Students
1. What is a fracture of a bone?
A fracture is a break or crack in the continuity of a bone. It occurs when a bone is subjected to force greater than it can withstand, such as during accidents, falls, or trauma. Fractures may vary in severity and can be:
- Simple (closed) fracture – bone breaks but does not pierce the skin.
- Compound (open) fracture – broken bone pierces through the skin.
- Greenstick fracture – partial break common in children.
2. What is dislocation of a bone?
A dislocation is the displacement of a bone from its normal position at a joint. It occurs when the bones forming a joint are forced out of alignment due to injury or excessive movement. Key features include:
- Severe joint pain and swelling
- Visible deformity
- Loss of joint movement
3. What is the difference between fracture and dislocation?
The main difference between a fracture and a dislocation is that a fracture involves a broken bone, while a dislocation involves displacement of a bone at a joint. Key distinctions include:
- Fracture – break in the bone structure.
- Dislocation – bone ends lose normal contact at a joint.
- Fractures affect bone continuity; dislocations affect joint alignment.
4. What are the common types of bone fractures?
Common types of bone fractures are classified based on the pattern and severity of the break. Major types include:
- Simple (closed) fracture
- Compound (open) fracture
- Comminuted fracture – bone breaks into multiple pieces.
- Greenstick fracture – incomplete break, common in children.
- Spiral fracture – caused by twisting force.
5. How does a bone heal after a fracture?
Bone healing after a fracture occurs through a natural repair process involving callus formation and remodeling. The stages include:
- Hematoma formation – blood clot forms at the fracture site.
- Soft callus formation – cartilage bridges the broken ends.
- Hard callus formation – bone replaces cartilage.
- Bone remodeling – bone regains original shape and strength.
6. What causes fractures and dislocations?
Fractures and dislocations are mainly caused by excessive force or trauma applied to bones and joints. Common causes include:
- Falls or accidents
- Sports injuries
- Road traffic collisions
- Weak bones due to osteoporosis
7. What are the symptoms of a fracture?
The main symptoms of a fracture include pain, swelling, and inability to move the affected part. Common signs are:
- Severe localized pain
- Swelling and bruising
- Deformity or abnormal angle
- Difficulty bearing weight
8. What are the symptoms of a dislocation?
A dislocation typically causes intense joint pain and visible deformity. Major symptoms include:
- Swelling around the joint
- Loss of normal movement
- Numbness or tingling (if nerves are compressed)
- Joint appearing out of place
9. Which joints are most commonly dislocated?
The shoulder joint is the most commonly dislocated joint in the human body. Other frequently affected joints include:
- Elbow joint
- Knee joint
- Finger joints
- Hip joint (especially in severe trauma)
10. Can a fracture and dislocation occur at the same time?
Yes, a fracture and dislocation can occur together in a severe injury, known as a fracture-dislocation. In this condition:
- The bone breaks near a joint.
- The broken bone segments are displaced from their normal position.
- Both bone structure and joint alignment are affected.
