Study Notes
Methods of Internal Fixation
- External fixation is gaining support as an alternative to internal fixation, particularly in the metaphyseal region of long bones.
- Tension band wiring technique is used in internal fixation.
External Fixation Devices
- External fixation device utilizing threaded half-pins anchored to an external bar by clamps.
Immobilization Methods
- Plaster cast is the standard method for most fractures.
- Synthetic (plastic) splinting materials have the key advantage of being lighter and more breathable than plaster bandages.
Functional Fixation
- Functional fixation involves the use of a supportive device that allows continued function of the part.
Fracture-Specific Fixation
- Internal fixation using a plate is most suitable for fractures near the middle of the shaft of long bones like the femur and tibia.
- Compression screw-plate, also known as dynamic hip screw (DHS), is commonly used in intertrochanteric fractures.
- Tension band wiring technique is most used in fractures of the patella and olecranon.
Explore the use of external fixation as an alternative to internal fixation in managing certain closed fractures of long bones, with a focus on the circular or Ilizarov frame configuration. Learn about different types of external fixation methods and their applications.
