Study Notes
General Principles
- Causes of fractures: Trauma, overuse, and underlying medical conditions
- Mechanisms of fractures: Direct impact, twisting, bending, or pulling forces
- Assessing injury: History, physical examination, and imaging
- Fracture emergencies: Open fracture, vascular injury, nerve injury, compartment syndrome
- Metaphyseal vs Diaphyseal Fractures:
- Metaphyseal fracture: Located in the end of a bone near a growth plate (epiphyseal plate)
- Healing: Occurs by bone ingrowth with little motion
- Movement: Limited as the metaphysis has lots of cancellous bone (spongy bone)
- Rapid Repair: Fracture consolidates in 3 weeks
Stability of Fractures
- Stable Fracture: Stays reduced with simple splintage, allowing good movement
- Unstable Fracture: Requires complex splinting to reduce and hold, as fragments translate/rotate
- Types of fractures:
- Oblique/spiral: Unstable due to translational/rotational displacement
- Avulsion: Unstable due to muscle pull keeping fragments separate
- Complete transverse translation: Unstable, may require operative or non-operative treatment
Treatment of Fractures
- Non-operative treatment: Analgesia, splints, protection, restoration of function
- Operative treatment: Reduction, fixation, arthroplasty, amputation
- Contraindications to operative treatment: Severe osteoporosis, active infection, severe comminution, severe soft tissue injury, poor general condition, undisplaced fracture
- Objectives of treatment: Restore function, prevent osteoarthritis
Reduction of Fractures
- Objective: Adequate apposition (touching) and normal alignment of fracture ends
- Imperfect apposition (touching) is sometimes acceptable, but imperfect alignment rarely is
- Methods: Manipulation, mechanical traction, open reduction
- Closed Reduction:
- Minimizes damage to soft tissue
- Relies on soft tissue attachments
- Rarely adequate for intra-articular fractures
- Difficult in infants whose bones are hard to visualize on X-ray
- Contraindications:
- Little or no displacement
- Displacement does not matter (e.g. clavicle, fibula)
- Reduction unlikely to succeed (e.g. compressed vertebral fracture)
Specific Fracture Examples
- Shoulder dislocation:
- Anterior: Conservative treatment
- Posterior: Operative ORIF
- Monteggia's: ORIF (Ulnar plating, reduce radial head), long arm cast at 90 degrees flexion
- Galeazzi's: ORIF (Radial plating, reduce ulnar head), long arm cast in supination
- Femur shaft fracture:
- Traction to overcome pull of quadriceps and hamstrings
- Intra-medullary nail
- Alternatives: External fixation (Ilizarov), plating
- Femur supracondylar, unicondylar, T and Y condylar fractures:
- Children: Plaster
- Other cases: Internal fixation for good reduction with early mobilization
Complications of Fractures
- Hypovolemic shock
- Fat embolism
- Delayed union, non-union
- Mal-union
- Limb shortening
- Knee stiffness
- Infection
