Overview of Bone Fractures
1. Classification of Fractures
- Closed Fracture: A fracture that does not involve a break in the skin, and therefore poses no risk of infection.
- Open Fracture: A fracture that involves a break in the skin, which increases the risk of infection.
2. Types of Fractures Based on Severity
a. Incomplete Fractures
- Greenstick Fracture: The bone bends but does not break completely. This type of fracture is common in children due to their flexible bones.
- Fissure Fracture: A partial break in the bone, affecting only a portion of the bone’s outer layer (cortex). This is also more common in children due to their weaker bones.
- Torus Fracture: The bone bulges outward at the fracture site due to pressure. This is also prevalent in children due to their growing bones.
b. Complete Fractures
- Comminuted Fracture: The bone breaks into multiple fragments.
- Spiral Fracture: The bone breaks due to a twisting force, resulting in a spiral-shaped fracture line.
- Transverse Fracture: The fracture line runs perpendicular to the bone’s long axis.
- Oblique Fracture: The fracture line runs diagonally across the bone.
- Avulsion Fracture: A small fragment of bone is pulled away from the main bone by a tendon or ligament.
3. Mechanism of Greenstick Fractures
- Bending Mechanism: The bone is bent beyond its capacity, leading to a fracture on the concave side (compressed side) of the bone.
- Tensile Fracture: The side of the bone that is stretched (tension side) breaks, resulting in a greenstick fracture.
4. Definition of Displacement
- Displacement: Refers to the movement of the fractured bone fragment away from its original position.
- Vertical Displacement: The fractured bone fragment moves along the length of the bone.
- Horizontal Displacement: The fractured bone fragment moves across the width of the bone.
- Rotational Displacement: The fractured bone fragment twists around its axis.
5. Definitive Signs of a Fracture
- Deformity: The fractured area appears abnormal compared to the opposite side.
- Abnormal Movement: Movement at the fracture site causes pain or is impossible.
- Crepitus: A grating sound heard when moving the fractured area.
6. Important Note
- Fractures are serious injuries and require timely and appropriate management.
- If you suspect a fracture, seek immediate medical attention at the nearest healthcare facility.
- Do not attempt to reposition or bandage a fracture yourself, as this can cause further damage.
7. Treatment Methods for Fractures
- Reduction and Immobilization (Casting): Applied to fractures without displacement or with minimal displacement.
- Surgery: Used for complex fractures, open fractures, or those with significant displacement. Surgical procedures may involve internal fixation (plates, screws) or external fixation (pins, rods).
8. Complications of Fractures
- Infection: A major risk with open fractures.
- Avascular Necrosis: The bone dies due to insufficient blood supply.
- Thromboembolism: Blood clots form in the blood vessels near the fracture site, blocking blood flow.
- Joint Stiffness: Improper healing of the fracture can lead to limited joint movement.
9. Fracture Rehabilitation
- Physical Therapy: Exercises to restore joint and muscle function.
- Avoidance of Strenuous Activities: Limiting heavy activity during the initial healing phase.
10. Prevention of Fractures
- Avoiding Hazardous Activities: Reducing participation in activities with high risk of fractures.
- Strengthening Bones: Consuming a diet rich in calcium and vitamin D.
- Protective Equipment: Wearing appropriate protective gear during sports or other activities.
