A Morphometric Study of Incisura Fibularis in South Indian Population with its Clinical Implications

Backgroud: The distal tibiofibular joint is formed by the medial convex surface of the distal end of the fibula and the lateral concave surface of the fibular incisura of the tibia. The bond between the tibia and the fibula at the level of the ankle is of utmost significance for the appropriate functioning of the distal tibiofibular joint. So, this study was done to measure various dimensions of fibular incisura of tibia and width of distal end of fibula. Materials and Method: 47 adult fully ossified dry tibias and 37 fibulae were taken for the study. Various measurements of fibular incisura of tibiae and width of distal end of fibulae were measured using vernier caliper. Results: The total (right + left) mean values of the width and depth of the incisura fibularis of tibia was 2.33 and 1.08cm. The total mean values of the length of anterior and posterior facet of incisura fibularis of tibia was 1.34 and 1.28cm. The total mean width of distal end of fibula was 2.44cm. Conclusion: The results of this study will be useful for biomedical peoples who make implants of lower end of tibia and fibula for orthopaedic surgeons during ankle reconstruction surgeries.
