External fixation is a key surgical technique for bone fractures, enabling damage control and deformity correction. Proper application of external fixators, following design principles, ensures successful patient outcomes.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
Background:
- External fixation is a primary method for surgical fracture treatment.
- It is crucial for managing complex fractures with extensive soft tissue damage and in polytraumatized patients.
Purpose of the Study:
- To highlight the versatility and applications of external fixation in orthopedic surgery.
- To outline the fundamental design and assembly principles of external fixators.
Main Methods:
- Review of the components and principles of external fixation.
- Discussion of its application in various surgical scenarios.
Main Results:
- External fixation is effective for damage control surgery, deformity correction, bone transport, arthrodesis, and septic surgery.
- A successful external fixation construct comprises bone fragment fixation, connecting rods/rings, and connectors.
Conclusions:
- Adherence to the principle of "form follows function" is essential for successful external fixation.
- External fixation offers a versatile and effective solution for a range of orthopedic challenges when applied correctly.
