Variations in calcanean facets in Indian Tali
Anatomischer Anzeiger
|January 1, 1979
Summary
This study classified calcanean articular facets in 500 Indian tali, revealing Type II (78%) as the most common pattern. Understanding these talar facet variations is crucial for anatomical and clinical studies.
Area of Science:
- Orthopedics
- Anatomy
- Anthropology
Background:
- The talus bone is critical for ankle articulation.
- Variations in the talar articular facets can impact biomechanics and surgical outcomes.
- Previous classifications of talar facets have not specifically focused on Indian populations.
Purpose of the Study:
- To observe and classify the patterns of calcanean articular facets in Indian tali.
- To establish a detailed morphological classification for talar facets in this population.
Main Methods:
- Examination of 500 Indian tali specimens.
- Observation and classification of calcanean articular facet patterns.
- Categorization into five distinct types based on facet morphology and arrangement.
Main Results:
- Five types of calcanean articular facets were identified.
- Type II, with a divided facet, was most prevalent (78%).
- Type I (16%), Type IV (3%), Type V (2%), and Type III (1%) showed decreasing frequencies.
Conclusions:
- A distinct classification of talar facet morphology in the Indian population has been established.
- The high prevalence of Type II facets suggests a common anatomical variation.
- This classification provides a baseline for further research in talar biomechanics and pathology.
