Summary
External fixator classification evolved from basic names to descriptive systems based on frame configuration. Current systems categorize fixators by type or configuration, aiding in veterinary orthopedic applications.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Veterinary medicine
Background:
- External fixators are crucial orthopedic devices.
- Classification has evolved from simple names to complex descriptions.
- Current systems include type I, II, III and descriptive unilateral/bilateral categories.
Purpose of the Study:
- To review and describe current classification systems for external fixators.
- To highlight the progression towards more descriptive categorization.
- To address challenges in classifying complex fixator configurations.
Main Methods:
- Review of existing classification systems for external fixators.
- Analysis of descriptive terminology used in veterinary orthopedics.
- Identification of limitations in current classification schemes.
Main Results:
- Two primary classification systems are in use: type I-III and descriptive (unilateral/bilateral, one-plane/two-plane).
- Veterinary orthopedics employs specific adjectives for common configurations.
- Complex fracture adaptations present challenges for easy classification.
Conclusions:
- External fixator classification is increasingly descriptive, focusing on frame configuration.
- Existing systems provide a framework but may not encompass all complex designs.
- Further refinement may be needed to classify highly adaptable fixator arrangements.
